If accutane cured acne, I wouldn't still have Acne after 40 years and 4 courses of the stuff in apr. 7 years. After each course, the oil soon returned and also the acne. Sure it was great having dry, clear skin for the first time since adolescence, but it didn't last for long and the side effects are powerful. I wouldn't do it again if I knew then what I know now. But obviously I know the desperation and was a big advocate at the time...just be aware and watch for Depression which can be very insidious.
I'd consider a natural method for your fungus...as with accutane, many drugs only work for a short time while wreaking havoc on the body.
