What Is Accutane? A Complete Guide to Isotretinoin

8 min readUpdated March 20, 2026

What Is Accutane?

Accutane is the original brand name for isotretinoin, a powerful oral medication derived from vitamin A. It's primarily prescribed for severe nodular acne that hasn't responded to other treatments, including antibiotics. While the Accutane brand was discontinued in 2009, isotretinoin is still widely available under generic names like Absorica, Claravis, Amnesteem, and Myorisan. Most people still refer to isotretinoin as "Accutane" regardless of the specific brand they take.

How Does Isotretinoin Work?

Isotretinoin works by dramatically reducing the size and output of your sebaceous (oil) glands — by up to 80%. This addresses acne at its root cause: excess oil production. The medication also reduces the amount of acne-causing bacteria on your skin, decreases inflammation, and helps normalize skin cell turnover so pores are less likely to clog. Unlike antibiotics or topical treatments that manage symptoms, isotretinoin can produce long-lasting or permanent remission of severe acne for many patients.

Who Is Accutane For?

Dermatologists typically prescribe isotretinoin for patients with severe cystic or nodular acne, acne that causes scarring, acne that hasn't improved with other treatments (antibiotics, retinoids, benzoyl peroxide), or moderate acne that is significantly impacting quality of life. It's considered a last-resort treatment because of its potency and the monitoring it requires, but for the right patients, it can be transformative.

What to Expect During Treatment

A typical Accutane course lasts 4 to 6 months, though some patients may need longer. You'll take a daily capsule with a fatty meal (fat helps your body absorb the medication). Most dermatologists start with a lower dose and increase gradually. You'll need monthly blood tests to monitor your liver function and cholesterol levels, and monthly check-ins with your dermatologist. Many patients experience a "purge" period in the first few weeks where acne temporarily worsens before improving.

The iPLEDGE Program

In the United States, isotretinoin is regulated through the iPLEDGE program, a risk management system designed to prevent birth defects (isotretinoin can cause severe fetal harm). All patients, pharmacies, and prescribers must be registered with iPLEDGE. Patients who can become pregnant must use two forms of contraception and take regular pregnancy tests. All patients must complete monthly check-ins through the iPLEDGE system to receive their prescription.
