Isotretinoin (Accutane) is a drug used to treat severe acne that hasn’t responded to other treatments. It may be prescribed for other uses. Some serious side effects have been reported from taking it.
Isotretinoin (Accutane) is a vitamin A derivative known as a retinoid. Your body reacts to it similar to how it reacts to vitamin A. Because vitamin A can build up in your tissues, it can quickly become a problem. You should not take vitamin A supplements while taking this drug.
Isotretinoin is available as a variety of brand names, including Absorica, Amnesteem, Claravis, Myorisan, and Sotret. The original brand, Accutane, is no longer on the market. However, the drug is sometimes still referred to by this name.
Since isotretinoin is designed to treat severe acne, it has a visible effect on the skin. The medication can be very effective in treating severe acne because it targets:
- clogged pores
- oil production
It’s important to know that when you first start using it, your acne may get worse before it gets better.
