SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety data reflect exposure to Fabior Foam in 744 patients with acne vulgaris. Patients were 12 years to 45 years of age and were treated once daily in the evening for 12 weeks. Adverse reactions reported in ≥ 1% of patients treated with Fabior Foam are presented in Table 1. Most adverse reactions were mild to moderate in severity. Severe adverse reactions represented 3.0% of the patients treated. Overall, 2.6% (20/744) of patients discontinued Fabior Foam because of local skin reactions.

Patients with any adverse reaction, n (%) 163 (22) 19 (3)
Application site irritation 107 (14) 9 (1)
Application site dryness 50 (7) 8 (1)
Application site erythema 48 (6) 3 ( < 1)

Application site pain 9 (1) 0
Application site photosensitivity (including sunburn) 8 (1) 3 ( < 1)
Application site pruritus 7 (1) 3 ( < 1)
Application site dermatitis 6 (1) 1 ( < 1)

Additional adverse reactions that were reported in < 1% of patients treated with Fabior Foam included application site reactions (including discoloration, discomfort, edema, rash and swelling), dermatitis, impetigo and pruritus.

Local skin reactions, dryness, erythema, and peeling actively assessed by the investigator and burning/stinging and itching reported by the patient were evaluated at baseline, during treatment, and end of treatment. During the 12 weeks of treatment, each local skin reaction peaked at week 2 and gradually reduced thereafter with the continued use of Fabior Foam.

DRUG INTERACTIONS

No formal drug-drug interaction studies were conducted with Fabior 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 Fabior 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 study 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 ethynyl estradiol, concomitant use of tazarotene did not affect the pharmacokinetics of norethindrone and ethynyl estradiol over a complete cycle.
