Head-to-head comparisons of medication uses, side effects, warnings, and more.
Isotretinoin (brands: Claravis, Absorica, Amnesteem, Myorisan, Zenatane) and Epiduo (adapalene/benzoyl peroxide) are both used to treat acne, but they have some key differences. Isotretinoin is an oral medication typically taken twice daily for 4 to 5 months at a time, while Epiduo is a topical gel applied once daily. Isotretinoin is a retinoic acid derivative that reduces oil production in the skin, whereas Epiduo combines a retinoid (adapalene) and a topical antibiotic (benzoyl peroxide) to stop pimples from forming and kill acne-causing bacteria. Isotretinoin can cause serious birth defects, so people who can get pregnant must follow strict birth control measures and register with the iPLEDGE program. Epiduo, on the other hand, can cause skin irritation but does not have the same severe birth defect risks. Isotretinoin is typically used for severe acne that hasn't responded to other treatments, while Epiduo is used for mild-to-moderate acne.
Isotretinoin is used to treat nodular acne that can't be cleared up by other acne treatments, including antibiotics. It's taken by mouth twice daily, typically for 4 to 5 months at a time. Because of the risk of serious birth defects, people who can get pregnant need to take pregnancy tests and use birth control before, during, and after treatment. Some common side effects include dry lips, dry skin, back pain, and dry eye. While isotretinoin is no longer available as brand name Accutane, you can still find it under other brands (e.g., Claravis and Amnesteem) and also as lower-cost generics.
Epiduo (adapalene / benzoyl peroxide) is a topical gel that contains two active ingredients: adapalene (a retinoid) and benzoyl peroxide (an antiseptic). It's FDA approved to treat acne (pimples) in adults and children. The gel is typically applied to the skin once a day. Side effects aren't common, but can include dry skin, skin irritation, and skin burning. The medication is available as a generic and under two brand names: Epiduo and Epiduo Forte.
