Most common adverse reactions reported at an incidence ≥6% are application site irritation, application site dryness, application site erythema, and application site exfoliation.

The safety data reflect exposure to Tazarotene Foam in 744 subjects with acne vulgaris. Subjects were aged 12 to 45 years and were treated once daily in the evening for 12 weeks. Adverse reactions reported in ≥ 1% of subjects treated with Tazarotene Foam are presented in Table 1. Most adverse reactions were mild to moderate in severity. Severe adverse reactions represented 3.0% of the subjects treated. Overall, 2.7% (20/744) of subjects discontinued Tazarotene Foam because of local skin reactions. Table 1.

Tazarotene Foam is contraindicated in pregnancy. Tazarotene Foam may cause fetal harm when administered to a pregnant woman. Tazarotene elicits teratogenic and developmental effects associated with retinoids after topical or systemic administration in rats and rabbits [see Use in Specific Populations (8.1 , 8.3) ]. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, treatment should be discontinued and the patient apprised of the potential hazard to the fetus [see Warnings and Precautions (5.1) , Use in Specific Populations (8.1 , 8.3) ]. Pregnancy. ( 4 , 8.1 )

No formal drug-drug interaction studies were conducted with Tazarotene Foam. Concomitant dermatologic medications and cosmetics that have a strong drying effect should be avoided. It is recommended to postpone treatment until the effects of these products subside before use of Tazarotene Foam is started. Concomitant use with oxidizing agents, such as benzoyl peroxide, may cause degradation of tazarotene and may reduce the clinical efficacy of tazarotene. If combination therapy is required, they should be applied at different times of the day (e.g., one in the morning and the other in the evening). The impact of tazarotene on the pharmacokinetics of progestin-only oral contraceptives (i.e., minipills) has not been evaluated. In a trial of 27 healthy female subjects between the ages of 20 to 55 years receiving a combination oral contraceptive tablet containing 1 mg norethindrone and 35 mcg ethinyl estradiol, concomitant use of tazarotene did not affect the pharmacokinetics of norethindrone and ethinyl estradiol over a complete cycle. Avoid concomitant dermatologic medications and cosmetics that have a strong drying effect. ( 7 )
