Isotretinoin is used to treat severe, disfiguring nodular acne. It should be used only after other acne medicines or antibiotics have been tried and have failed to help the acne. Isotretinoin may also be used to treat other skin diseases as determined by your doctor.
Isotretinoin must not be used to treat women who are able to bear children unless other forms of treatment have been tried first and have failed. Isotretinoin must not be taken during pregnancy because it causes birth defects in humans. If you are able to bear children, it is very important that you read, understand, and follow the pregnancy warnings for isotretinoin.
