Isotretinoin — Uses, Dosage, Side Effects & Safety

Drug class: Retinoid (oral anti-acne agent)

Overview

Isotretinoin is a powerful oral medication primarily used to treat severe, nodular, or cystic acne that has not responded to other treatments, such as antibiotics or topical therapies. It is also sometimes prescribed for other skin conditions as determined by your healthcare provider. Isotretinoin works by reducing the size and activity of the sebaceous (oil) glands in the skin, which decreases oil production, inflammation, and the formation of acne lesions. It also helps prevent clogged pores and reduces bacteria on the skin. Key points for patients: Isotretinoin is highly effective but can cause significant side effects, including serious birth defects if taken during pregnancy. Regular monitoring and strict adherence to your healthcare provider's instructions are essential. Women of childbearing age must use effective contraception before, during, and after treatment.
