SORIATANE is indicated for the treatment of severe psoriasis in adults. Because of significant adverse effects associated with its use, SORIATANE should be prescribed only by those knowledgeable in the systemic use of retinoids. In females of reproductive potential, SORIATANE should be reserved for non-pregnant patients who are unresponsive to other therapies or whose clinical condition contraindicates the use of other treatments (see boxed CONTRAINDICATIONS AND WARNINGS — SORIATANE can cause severe birth defects).
Most patients experience relapse of psoriasis after discontinuing therapy. Subsequent courses, when clinically indicated, have produced efficacy results similar to the initial course of therapy.
There is intersubject variation in the pharmacokinetics, clinical efficacy, and incidence of side effects with SORIATANE. A number of the more common side effects are dose-related. Individualization of dosage is required to achieve sufficient therapeutic response while minimizing side effects. Therapy with SORIATANE should be initiated at 25 to 50 mg per day, given as a single dose with the main meal. Maintenance doses of 25 to 50 mg per day may be given dependent upon an individual patient’s response to initial treatment. Relapses may be treated as outlined for initial therapy.
When SORIATANE is used with phototherapy, the prescriber should decrease the phototherapy dose, dependent on the patient’s individual response (see PRECAUTIONS: General).
Females who have taken TEGISON (etretinate) must continue to follow the contraceptive recommendations for TEGISON. TEGISON is no longer marketed in the US; for information, call Stiefel at 1-888-784-3335 (1-888-STIEFEL).
SORIATANE must only be dispensed in no more than a monthly supply. A SORIATANE Medication Guide must be given to the patient each time SORIATANE is dispensed, as required by law.
In the event of acute overdosage, SORIATANE must be withdrawn at once. Symptoms of overdose are identical to acute hypervitaminosis A (e.g., headache and vertigo). The acute oral toxicity (LD50) of acitretin in both mice and rats was greater than 4,000 mg per kg.
In one reported case of overdose, a 32-year-old male with Darier’s disease took 21 × 25-mg capsules (525-mg single dose). He vomited several hours later but experienced no other ill effects.
All female patients of childbearing potential who have taken an overdose of SORIATANE must:
1) Have a pregnancy test at the time of overdose; 2) Be counseled as per the boxed CONTRAINDICATIONS AND WARNINGS and PRECAUTIONS sections regarding birth defects and contraceptive use for at least 3 years' duration after the overdose.
Store between 15° and 25°C (59° and 77°F). Protect from light. Avoid exposure to high temperatures and humidity after the bottle is opened.
