Usually doctors recommend working up to around 1mg per kg of bodyweight. This doesn't mean that 40mg won't do anything though. Accutane comes in 20mg and 40mg form (10mg in countries outside North America as well). Usually you work your way up, though in many cases where the acne is not very severe, 40mg will do the job just fine.
i started at 40mg day for the last month. got blood work last week and going back to see my derm tomorrow. you have to get a new script every month, they are very strict about prescribing that stuff.. i dont know if he will up my dose or not.
My doc immediately prescribed 80mg, saying that at my weight I needed that much (only weight about 225). Today was my first day on it ... and yes, you have to get bloodwork every month, otherwise your derm won't renew your perscription
Damn, sometimes I wish my acne got bad enough to warrant accutane lol, I KNOW it would do a great job on me. Mine gets annoying sometimes but really it's never that bad, just to me it looks bad. I'll just take minocycline and that'll clear it up in a few weeks.
