I am now on my 4th month and everything is going well. My acne is clearing out and my dermotology doctor guarantees it will not come back. Try it for the first month if nothing really happens then the second month they will double your dosage.
The only thing that has happen to me is my face gets very dry and lips. I can deal with this. You also have to watch when you go out in the hot sun, put lots of lotion on otherwise you will look like a lobster.
I have one more month to go. My insurance doesn't cover the prescription thats why its so expensive. If I didn't take accutane my acne would have scarred.
