Accutane, also known by its generic name isotretinoin or brand name Roaccutane in some regions, is a potent medication primarily used in the treatment of severe acne. It is a form of vitamin A that works by reducing the amount of oil released by oil glands in your skin, helping your skin renew itself more quickly. Accutane is typically prescribed after other acne medicines or antibiotics have been tried without successful treatment of symptoms. Due to its strength and potential side effects, including birth defects if taken during pregnancy, it is usually considered a last-resort medication and is prescribed under strict medical supervision. Patients undergoing treatment with Accutane are closely monitored for side effects, and women of childbearing age are required to use effective birth control to prevent pregnancy during and for a period after treatment.
