Tretinoin capsules are indicated for the induction of remission in adults and pediatric patients 1 year of age and older with acute promyelocytic leukemia (APL) characterized by the presence of the t(15;17) translocation or PML/RARα gene expression, and who are refractory to or who have relapsed from anthracycline chemotherapy or for whom anthracycline-based chemotherapy is contraindicated. Tretinoin capsules are a retinoid indicated for induction of remission in adults and pediatric patients 1 year of age and older with acute promyelocytic leukemia (APL), characterized by presence of t(15;17) translocation or presence of PML/RARα gene expression, and who are refractory to or who have relapsed from anthracycline chemotherapy or for whom anthracycline-based chemotherapy is contraindicated.

Tretinoin capsules are contraindicated in patients with a known hypersensitivity to tretinoin capsules, any of its components, or other retinoids. Reactions have included rash, pruritus, face edema, and dyspnea [see Adverse Reactions ( 6.1 )]. Hypersensitivity to tretinoin capsules, any of its components, or other retinoids

• Patients Without t(15;17) Translocation or PML/RARα Fusion: Tretinoin capsules may be initiated based on morphological diagnosis of APL. Confirm diagnosis by detection of the t(15;17) translocation or PML/RARα fusion. ( 5.3 ) • Leukocytosis: Consider administering cytoreductive chemotherapy (including an anthracycline if not contraindicated or hydroxyurea) with tretinoin capsules in the setting of leukocytosis, as clinically indicated. ( 5.4 ) • Intracranial Hypertension: Tretinoin capsules have been associated with benign intracranial hypertension, especially in pediatric patients. Consider interruption, dose reduction, or discontinuation of tretinoin capsules as appropriate. ( 5.5 ) • Lipid Abnormalities: Patients experienced hypercholesterolemia and/or hypertriglyceridemia, which may be reversible upon completion of treatment. Monitor fasting triglycerides and cholesterol at baseline and periodically during treatment. ( 5.6 ) • Hepatotoxicity: Monitor liver function test results at baseline and during treatment as clinically indicated. ( 5.7 ) • Thromboembolic Events: Venous and arterial events have been reported; these events may occur during the first month of treatment with tretinoin capsules. ( 5.8 , 7.4 ) 5.1 Embryo-Fetal Toxicity Tretinoin capsules can cause embryo-fetal loss and malformations when administered to a pregnant woman. Tretinoin capsules are a retinoid and there is an increased risk of major congenital malformations, spontaneous abortions and …

8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action [see Clinical Pharmacology ( 12.1 )], tretinoin capsules can cause embryo-fetal loss and malformations when administered to a pregnant woman. Tretinoin capsules are a retinoid and there is an increased risk of major congenital malformations, spontaneous abortions and premature births following exposure to retinoids during pregnancy in humans. Tretinoin was teratogenic and embryotoxic in mice, rats, hamsters, rabbits and pigtail monkeys at doses less than the human dose on a mg/m 2 basis (see Data) . Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects …
