CONTRAINDICATIONS AND WARNINGS
ZenataneÂ™ must not be used by patients who are or may become pregnant. There is an extremely high risk that severe birth defects will result if pregnancy occurs while taking Zenatane in any amount, even for short periods of time. Potentially any fetus exposed during pregnancy can be affected. There are no accurate means of determining whether an exposed fetus has been affected.
Birth defects which have been documented following Zenatane exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. Cases of IQ scores less than 85 with or without other abnormalities have been reported. There is an increased risk of spontaneous abortion, and premature births have been reported.
Documented external abnormalities include: skull abnormality; ear abnormalities (including anotia, micropinna, small or absent external auditory canals); eye abnormalities (including microphthalmia); facial dysmorphia; cleft palate. Documented internal abnormalities include: CNS abnormalities (including cerebral abnormalities, cerebellar malformation, hydrocephalus, microcephaly, cranial nerve deficit); cardiovascular abnormalities; thymus gland abnormality; parathyroid hormone deficiency. In some cases death has occurred with certain of the abnormalities previously noted.
If pregnancy does occur during treatment of a patient who is taking Zenatane, Zenatane must be discontinued immediately and the patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling.
Special Prescribing Requirements
Because of Zenatane's teratogenicity and to minimize fetal exposure, Zenatane is approved for marketing only under a special restricted distribution program approved by the Food and Drug Administration. This program is called iPLEDGE ®. Zenatane must only be prescribed by prescribers who are registered and activated with the iPLEDGE Program. Zenatane must only be dispensed by a pharmacy registered and activated with iPLEDGE, and must only be dispensed to patients who are registered and meet all the requirements of iPLEDGE (see PRECAUTIONS).

Isotretinoin USP, a retinoid, is available as Zenatane (isotretinoin capsules, USP) in 10 mg, 20 mg, 30 mg and 40 mg soft gelatin capsules for oral administration. Each capsule contains butylatedhydroxyanisole, edetate disodium, hydrogenated vegetable oil (Type-I and Type-II), medium chain triglyceride, refined soybean oil and white wax. Gelatin capsules contain ferric oxide red, ferricoxide yellow (for 30 mg), gelatin, glycerin, methyl paraben, propyl paraben, lake blend blue(LB-332) containing D&C Yellow No.10, FD&C Blue No.1 (for 10 mg), lake blend red (LB-1574) containingD&C Red No.27, D&C Red No.30 (for 20 mg), lake blend green (LB-333) containing D&C Yellow No.10, FD&C Blue No.1 (for 40 mg), lake blend white (TLB-1774) containing FD&C Blue No.2, titaniumdioxide, and opacode black S-1-17823 containing iron oxide black, N-butyl alcohol, propylene glycol, ammonium hydroxide and shellac.
Chemically, isotretinoin is 13-cis-retinoic acid and is related to both retinoic acid and retinol (vitamin A). It is a yellow to slightly orange crystalline powder with a molecular weight of 300.44. Thestructural formula is:
Meets USP Dissolution Test 5.
Isotretinoin is a retinoid, which when administered in pharmacologic dosages of 0.5 to 1 mg/kg/day (see DOSAGE AND ADMINISTRATION), inhibits sebaceous gland function and keratinization. The exact mechanism of action of isotretinoin is unknown.
Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with Zenatane, and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.1
Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal. In a crossover study, 74 healthy adult subjects received a single 80 mg oral dose (2 x 40 mg capsules) of Zenatane under fasted and fed conditions. Both peak plasma concentration (Cmax) and the total exposure (AUC) of isotretinoin were more than doubled following a standardized high-fat meal when compared with Zenatane given under fasted conditions (see Table 2). The observed elimination half-life was unchanged. This lack of change in half-life suggests that food increases the bioavailability of isotretinoin without altering its disposition. The time to peak concentration (Tmax) was also increased with food and may be related to a longer absorption phase. Therefore, Zenatane should always be taken with food (see DOSAGE AND ADMINISTRATION). Clinical studies have shown that there is no difference in the pharmacokinetics of isotretinoin between patients with nodular acne and healthy subjects with normal skin.

*Eating a standardized high-fat meal
Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4-oxo-isotretinoin, retinoic acid (tretinoin), and 4-oxo-retinoic acid (4-oxotretinoin). Retinoic acid and 13-cis-retinoic acid are geometric isomers and show reversible interconversion. The administration of one isomer will give rise to the other. Isotretinoin is also irreversibly oxidized to 4-oxo-isotretinoin, which forms its geometric isomer 4-oxo-tretinoin.
After a single 80 mg oral dose of Zenatane to 74 healthy adult subjects, concurrent administration of food increased the extent of formation of all metabolites in plasma when compared to the extent of formation under fasted conditions.
All of these metabolites possess retinoid activity that is in some in vitro models more than that of the parent isotretinoin. However, the clinical significance of these models is unknown. After multiple oral dose administration of isotretinoin to adult cystic acne patients (â‰¥18 years), the exposure of patients to 4-oxo-isotretinoin at steady-state under fasted and fed conditions was approximately 3.4 times higher than that of isotretinoin.
In vitro studies indicate that the primary P450 isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6. Isotretinoin and its metabolites are further metabolized into conjugates, which are then excreted in urine and feces.
Following oral administration of an 80 mg dose of 14C-isotretinoin as a liquid suspension, 14C-activity in blood declined with a half-life of 90 hours. The metabolites of isotretinoin and any conjugates are ultimately excreted in the feces and urine in relatively equal amounts (total of 65% to 83%). After a single 80 mg oral dose of Zenatane to 74 healthy adult subjects under fed conditions, the mean ± SD elimination half-lives (t1/2) of isotretinoin and 4-oxo-isotretinoin were 21 ± 8.2 hours and 24 ± 5.3 hours, respectively. After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0.9 to 5.43 in patients with cystic acne.
The pharmacokinetics of isotretinoin were evaluated after single and multiple doses in 38 pediatric patients (12 to 15 years) and 19 adult patients (â‰¥18 years) who received Zenatane for the treatment of severe recalcitrant nodular acne. In both age groups, 4-oxo-isotretinoin was the major metabolite; tretinoin and 4-oxo-tretinoin were also observed. The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatric patients. There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients.

In pediatric patients (12 to 15 years), the mean ± SD elimination half-lives (t1/2) of isotretinoin and 4-oxo-isotretinoin were 15.7 ± 5.1 hours and 23.1 ± 5.7 hours, respectively. The accumulation ratios of isotretinoin ranged from 0.46 to 3.65 for pediatric patients.
Severe Recalcitrant Nodular Acne
Zenatane is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. â€œSevere,â€ by definition,2 means â€œmanyâ€ as opposed to â€œfew or severalâ€ nodules. Because of significant adverse effects associated with its use, Zenatane should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. In addition, Zenatane is indicated only for those patients who are not pregnant, because Zenatane can cause severe birth defects (see Boxed CONTRAINDICATIONS AND WARNINGS).
A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients.1,3,4 If a second course of therapy is needed, it should not be initiated until at least 8 weeks after completion of the first course, because experience has shown that patients may continue to improve while off Zenatane. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, Premature Epiphyseal Closure).
Pregnancy: Category X. See Boxed CONTRAINDICATIONS AND WARNINGS.
Zenatane is contraindicated in patients who are hypersensitive to this medication or to any of its components (see PRECAUTIONS: Hypersensitivity). Zenatane should not be given to patients who are sensitive to parabens, which are used as preservatives in the gelatin capsule.
Zenatane may cause depression, psychosis and, rarely, suicidal ideation, suicide attempts, suicide, and aggressive and/or violent behaviors. No mechanism of action has been established for these events (see ADVERSE REACTIONS: Psychiatric). Prescribers should read the brochure, Recognizing Psychiatric Disorders in Adolescents and Young Adults: A Guide for Prescribers of Isotretinoin. Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Zenatane therapy, patients and family members should be asked about any history of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary. Signs and symptoms of depression, as described in the brochure (â€œRecognizing Psychiatric Disorders in Adolescents and Young Adultsâ€), include sad mood, hopelessness, feelings of guilt, worthlessness or helplessness, loss of pleasure or interest in activities, fatigue, difficulty concentrating, change in sleep pattern, change in weight or appetite, suicidal thoughts or attempts, restlessness, irritability, acting on dangerous impulses, and persistent physical symptoms unresponsive to treatment. Patients should stop Zenatane and the patient or a family member should promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Zenatane therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk. Patients may report mental health problems or family history of psychiatric disorders. These reports should be discussed with the patient and/or the patientâ€™s family. A referral to a mental health professional may be necessary. The physician should consider whether Zenatane therapy is appropriate in this setting; for some patients the risks may outweigh the benefits of Zenatane therapy.
Zenatane use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines. Concomitant treatment with tetracyclines should therefore be avoided. Early signs and symptoms of pseudotumor cerebri include papilledema, headache, nausea and vomiting, and visual disturbances. Patients with these symptoms should be screened for papilledema and, if present, they should be told to discontinue Zenatane immediately and be referred to a neurologist for further diagnosis and care (see ADVERSE REACTIONS: Neurological).
There have been post-marketing reports of erythema multiforme and severe skin reactions [e.g., Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN)] associated with isotretinoin use. These events may be serious and result in death, life-threatening events, hospitalization, or disability. Patients should be monitored closely for severe skin reactions, and discontinuation of Zenatane should be considered if warranted.
Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has been reported. Zenatane should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur.
Elevations of serum triglycerides in excess of 800 mg/dL have been reported in patients treated with Zenatane. Marked elevations of serum triglycerides were reported in approximately 25% of patients receiving Zenatane in clinical trials. In addition, approximately 15% developed a decrease in high-density lipoproteins and about 7% showed an increase in cholesterol levels. In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Zenatane therapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose while continuing Zenatane 5.
Blood lipid determinations should be performed before Zenatane is given and then at intervals until the lipid response to Zenatane is established, which usually occurs within 4 weeks. Especially careful consideration must be given to risk/benefit for patients who may be at high risk during Zenatane therapy (patients with diabetes, obesity, increased alcohol intake, lipid metabolism disorder or familial history of lipid metabolism disorder). If Zenatane therapy is instituted, more frequent checks of serum values for lipids and/or blood sugar are recommended (see PRECAUTIONS: Laboratory Tests).
The cardiovascular consequences of hypertriglyceridemia associated with Zenatane are unknown.
Animal Studies: In rats given 8 or 32 mg/kg/day of isotretinoin (1.3 to 5.3 times the recommended clinical dose of 1 mg/kg/day after normalization for total body surface area) for 18 months or longer, the incidences of focal calcification, fibrosis and inflammation of the myocardium, calcification of coronary, pulmonary and mesenteric arteries, and metastatic calcification of the gastric mucosa were greater than in control rats of similar age. Focal endocardial and myocardial calcifications associated with calcification of the coronary arteries were observed in two dogs after approximately 6 to 7 months of treatment with isotretinoin at a dosage of 60 to 120 mg/kg/day (30 to 60 times the recommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area).
Impaired hearing has been reported in patients taking Zenatane; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Mechanism(s) and causality for this event have not been established. Patients who experience tinnitus or hearing impairment should discontinue Zenatane treatment and be referred for specialized care for further evaluation (see ADVERSE REACTIONS: Special Senses).
Clinical hepatitis considered to be possibly or probably related to Zenatane therapy has been reported. Additionally, mild to moderate elevations of liver enzymes have been observed in approximately 15% of individuals treated during clinical trials, some of which normalized with dosage reduction or continued administration of the drug. If normalization does not readily occur or if hepatitis is suspected during treatment with Zenatane, the drug should be discontinued and the etiology further investigated.
Zenatane has been associated with inflammatory bowel disease (including regional ileitis) in patients without a prior history of intestinal disorders. In some instances, symptoms have been reported to persist after Zenatane treatment has been stopped. Patients experiencing abdominal pain, rectal bleeding or severe diarrhea should discontinue Zenatane immediately (see ADVERSEREACTIONS: Gastrointestinal).
Bone Mineral Density
Effects of multiple courses of Zenatane on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiple courses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system. In an open-label clinical trial (N=217) of a single course of therapy with Zenatane for severe recalcitrant nodular acne, bone density measurements at several skeletal sites were not significantly decreased (lumbar spine change >-4% and total hip change >-5%) or were increased in the majority of patients. One patient had a decrease in lumbar spine bone mineral density >4% based on unadjusted data. Sixteen (7.9%) patients had decreases in lumbar spine bone mineral density >4%, and all the other patients (92%) did not have significant decreases or had increases (adjusted for body mass index). Nine patients (4.5%) had a decrease in total hip bone mineral density >5% based on unadjusted data. Twenty-one (10.6%) patients had decreases in total hip bone mineral density >5%, and all the other patients (89%) did not have significant decreases or had increases (adjusted for body mass index). Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baseline values. Total hip bone mineral densities remained below baseline (range â€“1.6% to â€“7.6%) in five of eight patients (62.5%).
In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Zenatane 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3.25% (see PRECAUTIONS: Pediatric Use).
Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the Zenatane population. While causality to Zenatane has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Zenatane be given at the recommended doses for no longer than the recommended duration.
A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2.24 mg/kg/day. Additionally, skeletal hyperostosis was noted in six of eight patients in a prospective study of disorders of keratinization.6 Minimal skeletal hyperostosis and calcification of ligaments and tendons have also been observed by x-ray in prospective studies of nodular acne patients treated with a single course of therapy at recommended doses. The skeletal effects of multiple Zenatane treatment courses for acne are unknown.
In a clinical study of 217 pediatric patients (12 to 17 years) with severe recalcitrant nodular acne, hyperostosis was not observed after 16 to 20 weeks of treatment with approximately 1 mg/kg/day of Zenatane given in two divided doses. Hyperostosis may require a longer time frame to appear. The clinical course and significance remain unknown.
Premature Epiphyseal Closure
There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Zenatane. The effect of multiple courses of Zenatane on epiphyseal closure is unknown.
Visual problems should be carefully monitored. All Zenatane patients experiencing visual difficulties should discontinue Zenatane treatment and have an ophthalmological examination (see ADVAERSE REACTIONS: Special Senses).
Corneal opacities have occurred in patients receiving Zenatane for acne and more frequently when higher drug dosages were used in patients with disorders of keratinization. The corneal opacities that have been observed in clinical trial patients treated with Zenatane have either completely resolved or were resolving at follow-up 6 to 7 weeks after discontinuation of the drug (see ADVERSE REACTIONS: Special Senses).
Decreased Night Vision
Decreased night vision has been reported during Zenatane therapy and in some instances the event has persisted after therapy was discontinued. Because the onset in some patients was sudden, patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night.
Zenatane must only be prescribed by prescribers who are registered and activated with the iPLEDGE Program. Zenatane must only be dispensed by a pharmacy registered and activated with iPLEDGE, and must only be dispensed to patients who are registered and meet all the requirements of iPLEDGE. Registered and activated pharmacies must receive Zenatane only from wholesalers registered with iPLEDGE.
iPLEDGE Program requirements for wholesalers, prescribers, and pharmacists are described below:
For the purpose of the iPLEDGE Program, the term wholesaler refers to wholesaler, distributor, and/or chain pharmacy distributor. To distribute Zenatane, wholesalers must be registered with iPLEDGE, and agree to meet all iPLEDGE requirements for wholesale distribution of isotretinoin products. Wholesalers must register with iPLEDGE by signing and returning the iPLEDGE wholesaler agreement that affirms they will comply with all iPLEDGE requirements for distribution of isotretinoin. These include:
- wholesalers registered in the iPLEDGE Program with prior written consent from the manufacturer or
- pharmacies licensed in the US and registered and activated in the iPLEDGE Program
To prescribe isotretinoin, the prescriber must be registered and activated with the pregnancy risk management program iPLEDGE. Prescribers can register by signing and returning the completed registration form. Prescribers can only activate their registration by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:
To prescribe isotretinoin, the prescriber must access the iPLEDGE system via the internet (www.ipledgeprogram.com) or telephone (1-866-495-0654) to:
1) Register each patient in the iPLEDGE Program.
2) Confirm monthly that each patient has received counseling and education.
3) For patients who can become pregnant::
Isotretinoin must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test.
Isotretinoin must only be dispensed by a pharmacy registered and activated with the pregnancy risk management program iPLEDGE and only when the registered patient meets all the requirements of the iPLEDGE Program. Meeting the requirements for a patient who can become pregnant signifies that the patient:
- For patients with regular menstrual cycles, the second pregnancy test should be done during the first 5 days of the menstrual period immediately preceding the beginning of isotretinoin therapy and after the patient has used two forms of contraception for one month.
- For patients with amenorrhea, irregular cycles, or using a contraceptive form that precludes withdrawal bleeding, the second pregnancy test must be done immediately preceding the beginning of isotretinoin therapy and after the patient has used two forms of contraception for one month.
If the patient has unprotected sexual contact with a partner that could result in pregnancy at any time one month before, during, or one month after therapy, the patient must:
1. Stop taking Zenatane immediately, if on therapy
2. Have a pregnancy test at least 19 days after the last act of unprotected sexual contact with a partner that could result in pregnancy.
3. Start using two forms of effective contraception simultaneously again for one month before resuming Zenatane therapy
4. Have a second pregnancy test after using two forms of effective contraception for one month as described above depending on whether the patient has regular menses or not.
Effective forms of contraception include both primary and secondary forms of contraception:
|Primary forms||Seconday forms|
|male vasectomy||male latex condom with or without spermicide|
|intrauterine device||diaphragm with spermicide|
|hormonal (combination oral contraceptives,transdermal patch,injectables, implantables, or vaginal ring)||cervical cap with spermicide|
vaginal sponge (contains spermicide)
Any birth control method can fail. There have been reports of pregnancy from patients who can become pregnant who have used oral contraceptives, as well as transdermal patch/injectable/ implantable/vaginal ring hormonal birth control products; these pregnancies occurred while these patients were taking Zenatane. These reports are more frequent for patients who use only a single form of contraception. Therefore, it is critically important that patients who can become pregnant use two effective forms of contraception simultaneously. Patients must receive written warnings about the rates of possible contraception failure (included in patient education kits).
Using two forms of contraception simultaneously substantially reduces the chances that a patient will become pregnant over the risk of pregnancy with either form alone. A drug interaction that decreases effectiveness of hormonal contraceptives has not been entirely ruled out for Zenatane (see PRECAUTIONS: Drug Interactions). Although hormonal contraceptives are highly effective, prescribers are advised to consult the package insert of any medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.
Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. Johnâ€™s Wort because a possible interaction has been suggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. Johnâ€™s Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. Johnâ€™s Wort.
If a pregnancy does occur during isotretinoin treatment, isotretinoin must be discontinued immediately. The patient should be referred to an Obstetrician-Gynecologist experienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure during or one month after isotretinoin therapy must be reported immediately to the FDA via the MedWatch number 1-800-FDA-1088 and also to the iPLEDGE Pregnancy Registry at 1-866-495-0654 or via the internet (www.ipledgeprogram.com).
Isotretinoin is contraindicated in patients who are pregnant. To receive isotretinoin all patients must meet all of the following conditions:
Patients Who Can Become Pregnant
Isotretinoin is contraindicated in patients who are pregnant. In addition to the requirements for all patients described above, patients who can become pregnant must meet the following conditions:
To dispense isotretinoin, pharmacies must be registered and activated with the pregnancy risk management program iPLEDGE.
The Responsible Site Pharmacist must register the pharmacy by signing and returning the completed registration form. After registration, the Responsible Site Pharmacist can only activate the pharmacy registration by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to the following points:
To dispense isotretinoin, the pharmacist must:
1) be trained by the Responsible Site Pharmacist concerning the iPLEDGE Program requirements.
2) obtain authorization from the iPLEDGE Program via the internet (www.ipledgeprogram.com), or telephone (1-866-495-0654) or through electronic telecommunication verification (via submission of an isotretinoin prescription claim) for every isotretinoin prescription. Authorization signifies that the patient has met all program requirements and is qualified to receive isotretinoin.
3) write the Risk Management Authorization (RMA) number on the prescription.
Zenatane must only be dispensed:
A Zenatane Medication Guide must be given to the patient each time Zenatane is dispensed, as required by law. This Zenatane Medication Guide is an important part of the risk management program for the patients.
Zenatane must not be prescribed, dispensed or otherwise obtained through the internet or any other means outside of the iPLEDGE Program. Only FDA-approved Zenatane products must be distributed, prescribed, dispensed, and used. Patients must obtain Zenatane prescriptions only at US licensed pharmacies.
A description of the iPLEDGE Program educational materials available with iPLEDGE is provided below. The main goal of these educational materials is to explain the iPLEDGE Program requirements and to reinforce the educational messages.
1) Guide to Best Practices for the iPLEDGE Program includes: isotretinoin teratogenic potential, information on pregnancy testing, and the method to complete a qualified isotretinoin prescription.
2) Prescriber Contraception Counseling Guide includes: specific information about effective contraception, the limitations of contraceptive forms, behaviors associated with an increased risk of contraceptive failure and pregnancy and the methods to evaluate pregnancy risk.
3) Pharmacist Guide includes: isotretinoin teratogenic potential and the method to obtain authorization to dispense an isotretinoin prescription.
4) The iPLEDGE Program is a systematic approach to comprehensive patient education about their responsibilities and includes education for contraception compliance and reinforcement of educational messages. The iPLEDGE Program includes information on the risks and benefits of Zenatane which is linked to the Medication Guide dispensed by pharmacists with each isotretinoin prescription.
5) Patients who cannot become pregnant and patients who can become pregnant are provided with separate booklets. Each booklet contains information on isotretinoin therapy including precautions and warnings, a Patient Information/Informed Consent (for all patients) form, and a toll-free line which provides isotretinoin information in two languages.
6) The booklet for patients who cannot become pregnant, Guide to Isotretinoin for Patients Who Cannot Get Pregnant, also includes information about male reproduction and a warning not to share isotretinoin with others or to donate blood during isotretinoin therapy and for one month following discontinuation of isotretinoin.
7) The booklet for patients who can become pregnant, Guide to Isotretinoin for Patients Who Can Get Pregnant, includes a referral program that offers patients free contraception counseling, reimbursed by the manufacturer, by a reproductive specialist; and a second Patient Information/Informed Consent About Birth Defects (for patients who can get pregnant) form concerning birth defects.
8) The booklet, Birth Control Workbook includes information on the types of contraceptive forms, the selection and use of appropriate, effective contraception, the rates of possible contraceptive failure and a toll-free contraception counseling line.
9) In addition, to the booklets, patient educational materials also include the iPLEDGE Program Birth Control Information Sheet and the following videos â€” â€œBe Prepared, Be Protectedâ€ and â€œBe Aware: The Risk of Pregnancy While on Isotretinoinâ€ (see Information for Patients).
Although an effect of Zenatane on bone loss is not established, physicians should use caution when prescribing Zenatane to patients with a genetic predisposition for age-related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism. This would include patients diagnosed with anorexia nervosa and those who are on chronic drug therapy that causes drug-induced osteoporosis/osteomalacia and/or affects vitamin D metabolism, such as systemic corticosteroids and any anticonvulsant.
Patients may be at increased risk when participating in sports with repetitive impact where the risks of spondylolisthesis with and without pars fractures and hip growth plate injuries in early and late adolescence are known. There are spontaneous reports of fractures and/or delayed healing in patients while on therapy with Zenatane or following cessation of therapy with Zenatane while involved in these activities. While causality to Zenatane has not been established, an effect must not be ruled out.
Information for Patients
Anaphylactic reactions and other allergic reactions have been reported. Cutaneous allergic reactions and serious cases of allergic vasculitis, often with purpura (bruises and red patches) of the extremities and extracutaneous involvement (including renal) have been reported. Severe allergic reaction necessitates discontinuation of therapy and appropriate medical management.
- Patients who can become pregnant must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initial Zenatane prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient for Zenatane. The second pregnancy test (a confirmation test) must be done in a CLIA-certified laboratory. The interval between the two tests must be at least 19 days.
- For patients with regular menstrual cycles, the second pregnancy test must be done during the first 5 days of the menstrual period immediately preceding the beginning of Zenatane therapy and after the patient has used 2 forms of contraception for 1 month.
- For patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding, the second pregnancy test must be done immediately preceding the beginning of Zenatane therapy and after the patient has used 2 forms of contraception for 1 month.
- Each month of therapy, patients must have a negative result from a urine or serum pregnancy test. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription.
In male and female Fischer 344 rats given oral isotretinoin at dosages of 8 or 32 mg/kg/day (1.3 to 5.3 times the recommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area) for greater than 18 months, there was a dose-related increased incidence of pheochromocytoma relative to controls. The incidence of adrenal medullary hyperplasia was also increased at the higher dosage in both sexes. The relatively high level of spontaneous pheochromocytomas occurring in the male Fischer 344 rat makes it an equivocal model for study of this tumor; therefore, the relevance of this tumor to the human population is uncertain.
The Ames test was conducted with isotretinoin in two laboratories. The results of the tests in one laboratory were negative while in the second laboratory a weakly positive response (less than 1.6 x background) was noted in S. typhimurium TA100 when the assay was conducted with metabolic activation. No dose response effect was seen and all other strains were negative. Additionally, other tests designed to assess genotoxicity (Chinese hamster cell assay, mouse micronucleus test, S.cerevisiae D7 assay, in vitro clastogenesis assay with human-derived lymphocytes, and unscheduled DNA synthesis assay) were all negative.
In rats, no adverse effects on gonadal function, fertility, conception rate, gestation or parturition were observed at oral dosages of isotretinoin of 2, 8, or 32 mg/kg/day (0.3, 1.3, or 5.3 times the recommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area).
In dogs, testicular atrophy was noted after treatment with oral isotretinoin for approximately 30 weeks at dosages of 20 or 60 mg/kg/day (10 or 30 times the recommended clinical dose of 1.0 mg/kg/day, respectively, after normalization for total body surface area). In general, there was microscopic evidence for appreciable depression of spermatogenesis but some sperm were observed in all testes examined and in no instance were completely atrophic tubules seen. In studies of 66 men, 30 of whom were patients with nodular acne under treatment with oral isotretinoin, no significant changes were noted in the count or motility of spermatozoa in the ejaculate. In a study of 50 men (ages 17 to 32 years) receiving Zenatane therapy for nodular acne, no significant effects were seen on ejaculate volume, sperm count, total sperm motility, morphology or seminal plasma fructose.
It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Zenatane.
The use of Zenatane in pediatric patients less than 12 years of age has not been studied. The use of Zenatane for the treatment of severe recalcitrant nodular acne in pediatric patients ages 12 to 17 years should be given careful consideration, especially for those patients where a known metabolic or structural bone disease exists (see PRECAUTIONS: General). Use of Zenatane in this age group for severe recalcitrant nodular acne is supported by evidence from a clinical study comparing 103 pediatric patients (13 to 17 years) to 197 adult patients (â‰¥18 years). Results from this study demonstrated that Zenatane, at a dose of 1 mg/kg/day given in two divided doses, was equally effective in treating severe recalcitrant nodular acne in both pediatric and adult patients.
In studies with Zenatane, adverse reactions reported in pediatric patients were similar to those described in adults except for the increased incidence of back pain and arthralgia (both of which were sometimes severe) and myalgia in pediatric patients (see ADVERSE REACTIONS).
In an open-label clinical trial (N=217) of a single course of therapy with Zenatane for severe recalcitrant nodular acne, bone density measurements at several skeletal sites were not significantly decreased (lumbar spine change >-4% and total hip change >-5%) or were increased in the majority of patients. One patient had a decrease in lumbar spine bone mineral density >4% based on unadjusted data. Sixteen (7.9%) patients had decreases in lumbar spine bone mineral density >4%, and all the other patients (92%) did not have significant decreases or had increases (adjusted for body mass index). Nine patients (4.5%) had a decrease in total hip bone mineral density >5% based on unadjusted data. Twenty-one (10.6%) patients had decreases in total hip bone mineral density >5%, and all the other patients (89%) did not have significant decreases or had increases (adjusted for body mass index). Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baseline values. Total hip bone mineral densities remained below baseline (range âˆ’1.6% to âˆ’7.6%) in five of eight patients (62.5%).
In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Zenatane 4 months after the first course, two patients showed a decrease in mean lumbar spine bone mineral density up to 3.25% (see WARNINGS: Skeletal: Bone Mineral Density).
Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. Although reported clinical experience has not identified differences in responses between elderly and younger patients, effects of aging might be expected to increase some risks associated with isotretinoin therapy (see WARNINGS and PRECAUTIONS).
The adverse reactions listed below reflect the experience from investigational studies of Zenatane, and the postmarketing experience. The relationship of some of these events to Zenatane therapy is unknown. Many of the side effects and adverse reactions seen in patients receiving Zenatane are similar to those described in patients taking very high doses of vitamin A (dryness of the skin and mucous membranes, e.g., of the lips, nasal passage, and eyes).
Cheilitis and hypertriglyceridemia are usually dose related. Most adverse reactions reported in clinical trials were reversible when therapy was discontinued; however, some persisted after cessation of therapy (see WARNINGS and ADVERSE REACTIONS).

White cells in the urine, proteinuria, microscopic or gross hematuria
The oral LD50 of isotretinoin is greater than 4000 mg/kg in rats and mice (>600 times the recommended clinical dose of 1 mg/kg/day after normalization of the rat dose for total body surface area and >300 times the recommended clinical dose of 1 mg/kg/day after normalization of the mouse dose for total body surface area) and is approximately 1960 mg/kg in rabbits (653 times the recommended clinical dose of 1 mg/kg/day after normalization for total body surface area). In humans, overdosage has been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolve without apparent residual effects.
Zenatane causes serious birth defects at any dosage (see Boxed CONTRAINDICATIONS AND WARNINGS). Patients who can become pregnant who present with isotretinoin overdose must be evaluated for pregnancy. Patients who are pregnant should receive counseling about the risks to the fetus, as described in the Boxed CONTRAINDICATIONS AND WARNINGS. Non-pregnant patients must be warned to avoid pregnancy for at least one month and receive contraceptive counseling as described in PRECAUTIONS. Educational materials for such patients can be obtained by calling the manufacturer. Because an overdose would be expected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients should use a condom, or avoid reproductive sexual activity with a patient who is or might become pregnant, for one month after the overdose. All patients with isotretinoin overdose should not donate blood for at least one month.
The recommended dosage range for Zenatane is 0.5 to 1 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1 mg/kg/day,8 it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, the dose may be adjusted according to response of the disease and/or the appearance of clinical side effects â€” some of which may be dose related. Adult patients whose disease is very severe with scarring or is primarily manifested on the trunk may require dose adjustments up to 2 mg/kg/day, as tolerated. Failure to take Zenatane with food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with food instructions.
The safety of once daily dosing with Zenatane has not been established. Once daily dosing is not recommended.
If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 months or more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth. Long-term use of Zenatane, even in low doses, has not been studied, and is not recommended. It is important that Zenatane be given at the recommended doses for no longer than the recommended duration. The effect of long-term use of Zenatane on bone loss is unknown (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, and Premature Epiphyseal closure).
Contraceptive measures must be followed for any subsequent course of therapy (see PRECAUTIONS).

Patient Information/Informed Consent About Birth Defects
(for patients who can get pregnant)
To be completed by the patient (and their parent or guardian* if patient is under age 18) and signed by their doctor.
Read each item below and initial in the space provided to show that you understand each item and agree to follow your doctor's instructions. Do not sign this consent and do not take isotretinoin if there is anything that you do not understand.
*A parent or guardian of a minor patient (under age 18) must also read and initial each item before signing the consent.
1. I understand that there is a very high chance that my unborn baby could have severe birth defects if I am pregnant or become pregnant while taking isotretinoin. This can happen with any amount and even if taken for short periods of time. This is why I must not be pregnant while taking isotretinoin.
2. I understand that I must not get pregnant one month before, during the entire time of my treatment, and for one month after the end of my treatment with isotretinoin.
3. I understand that I must avoid having any sexual contact (penis-vaginal) with a partner who could get me pregnant completely, or I must use two separate, effective forms of birth control (contraception) at the same time. The only exceptions are if I have had surgery to remove the uterus (a hysterectomy) or both of my ovaries (bilateral oophorectomy), or my doctor has medically confirmed that I am post-menopausal.
4. I understand that hormonal birth control products are among the most effective forms of birth control. Combination birth control pills and other hormonal products include skin patches, shots, under-the-skin implants, vaginal rings, and intrauterine devices (IUDs). Any method of birth control can fail. That is why I must use two different birth control forms at the same time, starting one month before, during, and for one month after stopping therapy every time I have any sexual contact (penis-vaginal) with a partner who could get me pregnant, even if one of the forms I choose is hormonal birth control.
5. I understand that the following are effective forms of birth control:
|Primary forms||Secondary forms|
|tying my tubes (tubal sterilization)||Barrier:|
|male vasectomy||male latex condom with or without spermicide|
|intrauterine device||diaphragm with spermicide|
|hormonal (combination birth control pills, skin patches, shots, under- the-skin implants, or vaginal ring)||cervical cap with spermicide|
|vaginal sponge (contains spermicide)|
A diaphragm and cervical cap must each be used with spermicide, a special cream that kills sperm
I understand that at least one of my two forms of birth control must be a primary form.
6. I will talk with my doctor about any medicines including herbal products I plan to take during my isotretinoin treatment because hormonal birth control forms may not work if I am taking certain medicines or herbal products.
7. I may receive a free birth control counseling session from a doctor or other family planning expert. My isotretinoin doctor can give me an Isotretinoin Contraception Referral Form for this free consultation.
8. I must begin using the birth control forms I have chosen as described above at least one month before I start taking isotretinoin.
9.I cannot get my first prescription for isotretinoin unless my doctor has told me that I have two negative pregnancy test results. The first pregnancy test should be done when my doctor decides to prescribe isotretinoin. The second pregnancy test must be done in a lab during the first 5 days of my menstrual period right before starting isotretinoin therapy treatment, or as instructed by my doctor. I will then have one pregnancy test; in a lab.
I must not start taking isotretinoin until I am sure that I am not pregnant, have negative results from two pregnancy tests, and the second test has been done in a lab.
10. I have read and understand the materials my doctor has provided to me, including the Guide to Isotretinoin for Patients Who Can Get Pregnant, Birth Control Workbook and Patient Introductory Brochure.
I have received information on emergency birth control.
My doctor provided me and asked me to watch a video about birth control and a video about birth defects and isotretinoin.
11. I must stop taking isotretinoin right away and call my doctor if I get pregnant, miss my expected menstrual period, stop using birth control, or have any sexual contact (penis-vaginal) with a partner who could get me pregnant without using my two birth control forms at any time.
12. My doctor provided me information about the purpose and importance of providing information to the iPLEDGE Program should I become pregnant while taking isotretinoin or within one month of the last dose. I understand that if I become pregnant, information about my pregnancy, my health, and my babyâ€™s health may be shared with the makers of isotretinoin, authorized parties who maintain the iPLEDGE Program for the makers of isotretinoin and government health regulatory authorities.
13. I understand that being qualified to receive isotretinoin in the iPLEDGE Program means that
My doctor has answered all my questions about isotretinoin and I understand that it is my responsibility not to get pregnant one month before, during isotretinoin treatment, or for one month after I stop taking isotretinoin.
I now authorize my doctor ________________ to begin my treatment with isotretinoin.

Patient Information/Informed Consent (for all patients):
To be completed by patient (and parent or guardian if patient is under age 18) and signed by the doctor.
Read each item below and initial in the space provided if you understand each item and agree to follow your doctorâ€™s instructions. A parent or guardian of a patient under age 18 must also read and understand each item before signing the agreement.
Do not sign this agreement and do not take isotretinoin if there is anything that you do not understand about all the information you have received about using isotretinoin.
1. I, ______________________________________________________,
understand that isotretinoin is a medicine used to treat severe nodular acne that cannot be cleared up by any other acne treatments, including antibiotics. In severe nodular acne, many red, swollen, tender lumps form in the skin. If untreated, severe nodular acne can lead to permanent scars.
2. My doctor has told me about my choices for treating my acne.
3. I understand that there are serious side effects that may happen while I am taking isotretinoin. These have been explained to me. These side effects include serious birth defects in babies of pregnant patients. [Note: There is a second Patient Information/Informed Consent About Birth Defects (for patients who can get pregnant)].
4. I understand that some patients, while taking isotretinoin or soon after stopping isotretinoin, have become depressed or developed other serious mental problems. Symptoms of depression include sad, â€œanxiousâ€ or empty mood, irritability, acting on dangerous impulses, anger, loss of pleasure or interest in social or sports activities, sleeping too much or too little, changes in weight or appetite, school or work performance going down, or trouble concentrating. Some patients taking isotretinoin have had thoughts about hurting themselves or putting an end to their own lives (suicidal thoughts). Some people tried to end their own lives. And some people have ended their own lives. There were reports that some of these people did not appear depressed. There have been reports of patients on isotretinoin becoming aggressive or violent. No one knows if isotretinoin caused these behaviors or if they would have happened even if the person did not take isotretinoin. Some people have had other signs of depression while taking isotretinoin (see #7 below).
5. Before I start taking isotretinoin, I agree to tell my doctor if I have ever had symptoms of depression (see #7 below), been psychotic, attempted suicide, had any other mental problems, or take medicine for any of these problems. Being psychotic means having a loss of contact with reality, such as hearing voices or seeing things that are not there.
6. Before I start taking isotretinoin, I agree to tell my doctor if, to the best of my knowledge, anyone in my family has ever had symptoms of depression, been psychotic, attempted suicide, or had any other serious mental problems.
7. Once I start taking isotretinoin, I agree to stop using isotretinoin and tell my doctor right away if any of the following signs and symptoms of depression or psychosis happen. I:
8. I agree to return to see my doctor every month I take isotretinoin to get a new prescription for isotretinoin, to check my progress, and to check for signs of side effects.
9. Isotretinoin will be prescribed just for me â€” I will not share isotretinoin with other people because it may cause serious side effects, including birth defects.
10. I will not give blood while taking isotretinoin or for 1 month after I stop taking isotretinoin. I understand that if someone who is pregnant gets my donated blood, their baby may be exposed to isotretinoin and may be born with serious birth defects.
11. I have read the Patient Introductory Brochure, and other materials my provider provided me containing important safety information about isotretinoin. I understand all the information I received.
12. My doctor and I have decided I should take isotretinoin. I understand that I must be qualified in the iPLEDGE Program to have my prescription filled each month. I understand that I can stop taking isotretinoin at any time. I agree to tell my doctor if I stop taking isotretinoin.
I now allow my doctor ___________________________ to begin my treatment with isotretinoin.
