Accutane.........yup, been there, done that! Accutane is definitely a miracle drug, in that is does cure your acne. However, the side effects to accutane are nothing less than miserable! The worst side effect is the dry skin. My lips and nostrils were the worst......oh and my hands because I wash them so much at work (I'm a nurse). Everytime I would blow my nose, it would be bloody (gross I know). I never experienced joint pain though. I am really surprised you physician didn't require a pregnancy test. Accutane is EXTREMELY harmful to a fetus. It is an absolute must that you take extra precaution with birth control (minimum of two forms). Accutane is also controled by the U.S. government now because it is such a dangerous drug. I had blood tests every month for pregnancy, anemia, liver functions, and cholesterol. My doctor monitored the results very closely. Like I said, this drug is nothing to mess around with. So, just out of concern for your safety, I would reccomend following up with a doctor who will monitor your blood tests every month.
Sorry for splurging all this on you. But just wanted to give you honest advice. Good luck! I know your skin will be beautiful when your 5 month course is done!
