Length of Accutane treatment
 

My derm said I will be on it for 4 months? Is this long enough? Will it be more likely to come back than if I took it for 6 months? I'm taking 40 mg the first month, either 60 or 80 mg the next month, and 80 mg the last two months and I weight about 80 kg(175 lbs.). How does this sound?
