Adapalene Topical Solution, 0.1% is indicated for the topical treatment of acne vulgaris.

Remove swab from foil just before using. Adapalene solution should be applied once a day to affected areas. Before retiring in the evening, wash and dry areas to be treated. Apply a thin film of medication to the affected areas. Avoid the eyes, lips, and mucous membranes. Discard swab after single use. Do not use if seal is broken. During the early weeks of therapy, an apparent exacerbation of acne may occur. This is due to the action of the medication on previously unseen lesions and should not be considered a reason to discontinue therapy. Therapeutic results should be noticed after eight to twelve weeks of treatment.

Adapalene Topical Solution, 0.1% should not be administered to individuals who are hypersensitive to adapalene or any of the components in the vehicle solution.

Some adverse effects such as erythema, scaling, dryness, pruritus, and burning will occur in 30-60% of patients. Pruritus or burning immediately after application also occurs in approximately 30% of patients. The following additional adverse experiences were reported in approximately 1% or less of patients: skin irritation, burning/stinging, erythema, sunburn, and acne flares. These are most commonly seen during the first month of therapy and decrease in frequency and severity thereafter. All adverse effects with the use of adapalene solution during clinical trials were reversible upon discontinuation of therapy.

As Adapalene Topical Solution, 0.1% has the potential to produce local irritation in some patients, concomitant use of other potentially irritating topical products (medicated or abrasive soaps and cleansers, soaps and cosmetics that have a strong drying effect, and products with high concentrations of alcohols, astringents, spices or lime) should be approached with caution. Particular caution should be exercised in using preparations containing sulfur, resorcinol, or salicylic acid in combination with Adapalene Topical Solution, 0.1%. If these preparations have been used, it is advisable not to start therapy with Adapalene Topical Solution, 0.1% until the effects of such preparations in the skin have subsided.
