Epiduo

Epiduo is Galderma's brand name for a prescription topical ointment for the treatment of acne. It consists of a combination of adapalene (0.1%) and benzoyl peroxide (2.5%).

Patients are advised to exercise caution in using Epiduo together with other skin products containing sulfur, resorcinol, or salicylic acid, or with medicated or abrasive soaps and cleansers.

Skin products with high levels of alcohol or astringents should also be avoided. Using topical products with a strong drying effect in combination with Epiduo can increase irritation.
