Warning and Cautions
Ultraviolet Light and Environmental Exposure: Avoid exposure to sunlight and sunlamps. Wear sunscreen when sun exposure cannot be avoided. (5.1) Erythema, scaling, dryness, stinging/burning, irritant and allergic contact dermatitis may occur with use of EPIDUO gel and may necessitate discontinuation. (5.2) 5.1 Ultraviolet Light and Environmental Exposure Exposure to sunlight, including sunlamps, should be minimized during the use of EPIDUO gel. Patients with high levels of sun exposure and those with inherent sensitivity to sun should exercise particular caution. Use of 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 gel. 5.2 Local Cutaneous Reactions Erythema, scaling, dryness, and stinging/burning may be experienced with use of EPIDUO gel. 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 gel, 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 gel. 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).
Most commonly reported adverse events (≥1%) in patients treated with EPIDUO gel were dry skin, contact dermatitis, application site burning, application site irritation and skin irritation.

During clinical trials, 1401 subjects were exposed to EPIDUO gel. A total of 1036 subjects with acne vulgaris, 12 years and older, were treated once daily for 12 weeks to 12 months. Related adverse events reported within 12 weeks of treatment and in at least 1% of subjects treated with EPIDUO gel and those reported in subjects treated with the vehicle gel are presented in Table 1: Table 1. Drug Related Adverse Events Reported in Clinical Trials by at Least 1% of Patients Treated For 12 Weeks System Organ Class/Preferred Term EPIDUO Gel N=564 Vehicle Gel N=489 Subjects with AE(s) 14% 4% Dry skin 7% 2% Contact dermatitis 3% <1% Application site burning 2% <1% Application site irritation 1% <1% Skin irritation 1% 0% Local tolerability evaluations, presented in Table 2, were conducted at each study visit in clinical trials by assessment of erythema, scaling, dryness, burning, and stinging. Table 2. Incidence of Local Cutaneous Irritation in Controlled Clinical Trials (N = 553) Treatment Emergent Signs and Symptoms Maximum Severity During Treatment End of Treatment Severity (12 weeks) Mild Moderate Severe Mild Moderate Severe Erythema 27% 13% 1% 8% 2% 1% Scaling 35% 11% 1% 9% 1% <1% Dryness 41% 13% 1% 10% 2% <1% Stinging/burning 41% 15% 3% 7% 2% 1% Analysis over the 12-week period showed that local tolerability scores for erythema, scaling, dryness, and stinging/burning peaked at Week 1 of therapy and decreased thereafter. During a pediatric clinical trial, 285 children with acne vulgaris, 9 to 11 years of age were treated with EPIDUO gel or with the vehicle gel once daily for 12 weeks. Overall, the safety profile of EPIDUO gel in these subjects is comparable to the safety profile observed in older subjects 12 years of age and above, both in the nature and frequency of the observed adverse events. Analysis of local tolerability evaluations shows similar incidence of treatment emergent signs and symptoms as in subjects 12 years of age and above, with local tolerability signs and symptoms peaking during the first week and decreasing over time. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of EPIDUO gel: eyelid edema, sunburn, blister, pain of skin, pruritus, swelling face, conjunctivitis, skin discoloration, rash, eczema, throat tightness and allergic contact dermatitis. 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.
Concomitant topical acne therapy should be used with caution because a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. No formal drug-drug interaction studies were conducted with EPIDUO gel.
Use In Specific Populations
8.1 Pregnancy Pregnancy Category C. There are no well-controlled trials in pregnant women treated with EPIDUO gel. Animal reproduction studies have not been conducted with the combination gel or benzoyl peroxide. Furthermore, such studies are not always predictive of human response; therefore, EPIDUO gel should be used during pregnancy only if the potential benefit justifies the risk to the fetus. No teratogenic effects were observed in rats treated with oral doses of 0.15 to 5.0 mg adapalene/kg/day, up to 25 times (mg/m2/day) the maximum recommended human dose (MRHD) of 2 grams of EPIDUO gel. However, teratogenic changes were observed in rats and rabbits when treated with oral doses of ≥ 25 mg adapalene/kg/day representing 123 and 246 times MRHD, respectively. Findings included cleft palate, microphthalmia, encephalocele and skeletal abnormalities in rats; and umbilical hernia, exophthalmos and kidney and skeletal abnormalities in rabbits. Dermal teratology studies conducted in rats and rabbits at doses of 0.6-6.0 mg adapalene/kg/day [25-59 times (mg/m2) the MRHD] exhibited no fetotoxicity and only minimal increases in supernumerary ribs in both species and delayed ossification in rabbits. 8.3 Nursing Mothers It is not known whether adapalene or benzoyl peroxide is excreted in human milk following use of EPIDUO gel. Because many drugs are excreted in human milk, caution should be exercised when EPIDUO gel is administered to a nursing woman. 8.4 Pediatric Use Safety and effectiveness of EPIDUO gel in pediatric patients under the age of 9 have not been established. 8.5 Geriatric Use Clinical studies of EPIDUO gel did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
