2 DOSAGE AND ADMINISTRATION For topical use only. EPIDUO FORTE is not for oral, ophthalmic, or intravaginal use. Apply a thin layer of EPIDUO FORTE to affected areas of the face and/or trunk once daily after washing. Use a pea-sized amount for each area of the face (e.g., forehead, chin, each cheek). Wash hands after application as EPIDUO FORTE may bleach hair or colored fabrics. Avoid the eyes, lips and mucous membranes.

4 CONTRAINDICATIONS EPIDUO FORTE is contraindicated in patients with a history of hypersensitivity reactions to benzoyl peroxide or any components of the formulation in EPIDUO FORTE. EPIDUO FORTE is contraindicated in patients with a history of hypersensitivity reactions to benzoyl peroxide or any components of the formulation in EPIDUO FORTE. ( 4 )

5 WARNINGS AND PRECAUTIONS Hypersensitivity: Severe hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with the use of benzoyl peroxide products. ( 5.1 ) Photosensitivity: Avoid exposure to sunlight and sunlamps. Wear broad spectrum sunscreen and protective clothing when sun exposure cannot be avoided. ( 5.2 ) Skin Irritation: Erythema, scaling, dryness, stinging/burning, irritant and allergic contact dermatitis may occur with use of EPIDUO FORTE and may necessitate discontinuation. ( 5.3 ) 5.1 Hypersensitivity Hypersensitivity reactions, including anaphylaxis, angioedema, and urticaria, have been reported with the use of benzoyl peroxide products. If a serious hypersensitivity reaction occurs, discontinue EPIDUO FORTE immediately and initiate appropriate therapy. 5.2 Photosensitivity Avoid exposure to sunlight, including sunlamps, during the use of EPIDUO FORTE. Patients with high levels of sun exposure and those with inherent sensitivity to sun should exercise particular caution. Use of broad spectrum sunscreen products and protective apparel (e.g., hat) are recommended when exposure cannot be avoided. Weather extremes, such as wind or cold, may be irritating to patients under treatment with EPIDUO FORTE. 5.3 Skin Irritation/Contact Dermatitis Erythema, scaling, dryness, and stinging/burning may be experienced with use of EPIDUO FORTE. These are most likely to occur during the first four weeks of treatment, are mostly mild to moderate in intensity, and usually lessen with continued use of the medication. Irritant and allergic contact dermatitis may occur. Depending upon the severity of these adverse reactions, patients should be instructed to use a moisturizer, reduce the frequency of the application of EPIDUO FORTE, or discontinue use. The product should not be applied to cuts, abrasions, eczematous or sunburned skin. As with other retinoids, use of “waxing” as a depilatory method should be avoided on skin treated with EPIDUO FORTE. Avoid concomitant use of other potentially irritating topical products (medicated or abrasive soaps and cleansers, soaps and cosmetics that have strong skin-drying effect and products with high concentrations of alcohol, astringents, spices or limes).

6 ADVERSE REACTIONS The most common adverse reactions (incidence ≥1%) are skin irritation, eczema, atopic dermatitis and skin burning sensation.

During the randomized, double-blind, vehicle- and active-controlled clinical trial, 217 subjects were exposed to EPIDUO FORTE. A total of 197 subjects with acne vulgaris, 12 years and older, were treated once daily for 12 weeks. Adverse reactions reported within 12 weeks of treatment in at least 1% of subjects treated with EPIDUO FORTE and for which the rate with EPIDUO FORTE exceeded the rate for the vehicle are presented in Table 1: Table 1. Adverse Reactions Occurring in ≥ 1% of Subjects with Acne Vulgaris in a 12-week Clinical Trial EPIDUO FORTE (N=217) Adapalene and Benzoyl Peroxide Gel, 0.1%/2.5% (N=217) Vehicle (N=69) Skin irritation 4% <1% 0% Eczema 1% 0% 0% Dermatitis atopic 1% 0% 0% Skin burning sensation 1% 0% 0% Local tolerability evaluations presented in Table 2, were conducted at each trial visit in the clinical trial by assessment of erythema, scaling, dryness, and stinging/burning, which peaked at Week 1 of therapy and decreased thereafter.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and subcutaneous tissue disorders : sunburn, blister (including vesicles and bullae), pruritus, hyperpigmentation and hypopigmentation..

8.1 Pregnancy Risk Summary Available pharmacovigilance data with EPIDUO FORTE use in pregnant women are insufficient to establish a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Animal reproduction studies have not been conducted with the combination gel. Adapalene gel, 0.3% Available data from clinical trials with adapalene gel 0.3% use in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of adapalene to pregnant rats and rabbits during organogenesis at dose exposures 41 and 81 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 2 g resulted in fetal skeletal and visceral malformations (see Data). Benzoyl peroxide gel, 2.5% The systemic exposure of benzoyl peroxide is unknown. Based on published literature, benzoyl peroxide is rapidly metabolized to benzoic acid (an endogenous substance), which is eliminated in the urine. Hence, maternal use is not expected to result in fetal exposure of the drug. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data No malformations were observed in rats treated with oral adapalene doses of 0.15 to 5.0 mg/kg/day, up to 8 times the MRHD of 2 grams of EPIDUO FORTE based on a mg/m2 comparison. However, malformations were observed in rats and rabbits when treated with oral doses of ≥ 25 mg/kg/day adapalene (41 and 81 times the MRHD, respectively, based on a mg/m2 comparison). Findings included cleft palate, microphthalmia, encephalocele, and skeletal abnormalities in rats and umbilical hernia, exophthalmos, and kidney and skeletal abnormalities in rabbits. Dermal adapalene embryofetal development studies in rats and rabbits at doses up to 6.0 mg/kg/day (9.7 and 19.5 times the MRHD, respectively, based on a mg/m2 comparison) exhibited no fetotoxicity and only minimal increases in skeletal variations (supernumerary ribs in both species and delayed ossification in rabbits).
