IMPORTANT SAFETY INFORMATION (CONT’D)
WARNINGS |
| • |
Pseudotumor Cerebri: Accutane 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 Accutane immediately and be referred to a neurologist for further diagnosis and care. |
|
| • |
Serious Skin Reactions: 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 Accutane should be considered if warranted. |
|
| • |
Pancreatitis: Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has been reported. Accutane should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if
symptoms of pancreatitis occur. |
|
| • |
Lipids: Elevations of serum triglycerides in excess of 800 mg/dL have been reported in patients treated with Accutane. Marked elevations of serum triglycerides and cholesterol levels and a decrease in high-density lipoproteins were reported in clinical trials. Blood lipid determinations should be
performed before Accutane is given and then at intervals until the lipid response to Accutane 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 Accutane therapy (patients with diabetes, obesity, increased alcohol intake, lipid metabolism disorder or familial history of lipid metabolism disorder). If Accutane therapy is instituted, more frequent checks of serum values for lipids and/or
blood sugar are recommended. The cardiovascular consequences of hypertriglyceridemia associated with Accutane are unknown. |
|
| • |
Hearing Impairment: Impaired hearing has been reported in patients taking Accutane; in some cases, the hearing impairment has been reported to persist after therapy has been discontinued. Patients who experience tinnitus or hearing impairment should discontinue Accutane treatment and be referred
for specialized care for further evaluation. |
|
| • |
Hepatotoxicity: Clinical hepatitis considered to be possibly or probably related to Accutane therapy has been reported. Elevations of liver enzymes have been observed in 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 Accutane, the drug should be discontinued and the etiology further investigated. |
|
| • |
Inflammatory Bowel Disease: Accutane 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 Accutane treatment has been stopped. Patients
experiencing abdominal pain, rectal bleeding or severe diarrhea should discontinue Accutane immediately. |
|
| • |
Bone Mineral Density Changes: Although effects of multiple courses of Accutane on the developing musculoskeletal system are unknown, there is some evidence that Accutane may affect bone mineral density in some patients. Other skeletal conditions such as spontaneous reports of osteoporosis,
osteopenia, bone fractures, delayed healing of bone fractures, and premature epiphyseal closure have been seen in the Accutane population. A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization. |
|
| • |
Visual Impairment: Visual problems should be carefully monitored. All Accutane patients experiencing visual difficulties should discontinue Accutane treatment and have an ophthalmological examination. Corneal opacities have been reported in some patients. Decreased night vision has been reported
during Accutane therapy and in some instances the event has persisted after therapy was discontinued. Patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night. |
|
| ADVERSE REACTIONS |
| • |
Most of the adverse reactions seen in Accutane patients are similar to those described in patients taking very high doses of vitamin A. The common, less serious side effects of Accutane include dry skin, chapped lips, dry eyes, and dry nose that may lead to nosebleeds. |
|
| • |

|
| • |
Hematologic: allergic reactions, anemia, thrombocytopenia, neutropenia, rare reports of agranulocytosis. See Laboratory Tests for other hematological parameters. |
|
| • |
Musculoskeletal: skeletal hyperostosis, calcification of tendons and ligaments, premature epiphyseal closure, decreases in bone mineral density, musculoskeletal symptoms (sometimes severe) including back pain, myalgia, and arthralgia, transient pain in the chest, arthritis, tendonitis, other
types of bone abnormalities, elevations of CPK/rare reports of rhabdomyolysis. |

|
| • |
Urinary System: glomerulonephritis, nonspecific urogenital findings |
|
| DRUG INTERACTIONS |
| • |
Vitamin A: Because of the relationship of Accutane to vitamin A, patients should be advised against taking vitamin supplements containing vitamin A to avoid additive toxic effects. |
|
| • |
Tetracyclines: Concomitant treatment with Accutane should be avoided because Accutane use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines. |
|
| • |
Micro-dosed Progesterone Preparations: Micro-dosed progesterone preparations (“minipills” that do not contain an estrogen) may be an inadequate method of contraception during Accutane therapy. It is not known if hormonal contraceptives differ in their effectiveness when used with
Accutane. Therefore, it is critically important for patients who can become pregnant to select and commit to use two forms of effective contraception simultaneously, at least one of which must be a primary form. |
|
| • |
Norethindrone/ethinyl estradiol: In a study, patients receiving Ortho-Novum® 7/7/7 Tablets as an oral contraceptive agent, Accutane at the recommended dose of 1 mg/kg/day, did not induce clinically
relevant changes in the pharmacokinetics of ethinyl estradiol and norethindrone and in the serum levels of progesterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Prescribers are advised to consult the package insert of medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products. |
|
| • |
St. John’s Wort: Accutane use is associated with depression in some patients. Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John’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. John’s Wort. Pregnancies have been reported by users of combined hormonal contraceptives who also used some form of St. John’s Wort. |
|
| • |
Phenytoin: Phenytoin is known to cause osteomalacia. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between phenytoin and Accutane. Therefore, caution should be exercised when using these drugs together. |
|
| • |
Systemic Corticosteroids: Systemic corticosteroids are known to cause osteoporosis. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between systemic corticosteroids and Accutane. Therefore, caution should be exercised when using these
drugs together. |
|
| USE IN SPECIFIC POPULATIONS |
| • |
Nursing Mother: It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Accutane. |
|
| • |
Pediatric Use: Accutane in pediatric patients less than 12 years of age has not been studied. The use of Accutane 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. |
|
| • |
Geriatric Use: Studies did not include sufficient patients aged 65 years and over to determine if they respond differently from younger patients, although effects of aging might be expected to increase some risks associated with isotretinoin therapy. |
