Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the 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.
In human dermal safety trials, TAZORAC® Cream, 0.05% and 0.1% did not induce allergic contact sensitization, phototoxicity, or photoallergy.
The most frequent adverse reactions reported with TAZORAC® Cream, 0.05% and 0.1% occurring in 10 to 23% of subjects, in descending order, included pruritus, erythema, and burning. Reactions occurring in greater than 1 to less than 10% of subjects, in descending order, included irritation, desquamation, stinging, contact dermatitis, dermatitis, eczema, worsening of psoriasis, skin pain, rash, hypertriglyceridemia, dry skin, skin inflammation, and peripheral edema.
TAZORAC® Cream, 0.1% was associated with a greater degree of local irritation than the 0.05% cream. The rates of irritation adverse reactions reported during psoriasis trials with TAZORAC® Cream, 0.1% were 0.1 0.4% higher than those reported for TAZORAC® Cream, 0.05%.

No formal drug-drug interaction studies were conducted with TAZORAC® Cream.
In a trial of 27 healthy female subjects between the ages of 20 – 55 years receiving a combination oral contraceptive tablet containing 1 mg norethindrone and 35 μg ethinyl estradiol, concomitant use of tazarotene administered as 1.1 mg orally (mean ± SD Cmax and AUC0-24 of tazarotenic acid were 28.9 ± 9.4 ng/mL and 120.6 ± 28.5 ng*h/mL) did not affect the pharmacokinetics of norethindrone and ethinyl estradiol over a complete cycle.
The impact of tazarotene on the pharmacokinetics of progestin only oral contraceptives (i.e., minipills) has not been evaluated.
