How do i know if i need accutane?

Last resort : Accutane is a very powerful medication and should be used for stubborn acne (especially cystic) which has not responded to oral antibiotics or birth control pills. Possible side effects of Accutane include dry eyes, dry lips, headaches, bone pain, bone spurs, mood changes, liver problems, elevated cholesterol, hair loss, and possible increased risk of crohn's disease, an inflammatory bowel disease.
