Can Accutane make me gain weight?

No, Accutane specifically does not cause weight gain. Accutane should be taken with higher calorie, fattier foods, so if you aren't eating those and change your diet to compensate for that, it could cause weight gain I suppose. "This answer has been solicited without seeing this patient and
