I have to agree with mod Moonlight, if your acne is not that bad and your young then I would try other options. It can have a severe effect on the bones and that has been known since the drug first came out and Roche has always stated that. Yes, It can cause epiphyseal closure which would stunt your growth, is this going to happen no one knows. If it is related to hormones well then Accutane may work temporarily and remember it is not a 100% guarantee to cure any acne permanently.
I have no family hx of type 1 diabetes or other autoimmune in my family and I took Accutane at 32 and well the side effect listed at the time was "may cause sugar alterations" recently it now states may cause diabetes. I am a type 1 diabetic now due to Accutane.
It's Russian Roulette and If your really wanting to take it then I would do a extremely low dose!
