The endpoint is not a self-test
One U.S. isotretinoin capsule has a 15-to-20-week course. It also allows an earlier endpoint when the total nodule count has fallen by more than 70% before the course ends. Your health care provider should tell you how long treatment lasts.
Frequently asked questions
Is clear skin enough reason to stop Accutane?
No. Clear skin alone does not determine the endpoint; course length and a defined acne-response endpoint also matter.
Can I extend the course if I still have breakouts?
No—do not extend the course yourself. Your health care provider should tell you how long treatment lasts.
