Isotretinoin
"I have been taking 30 mg once daily for the last month. It's definitely doing something. I've broken out everywhere and I mean everywhere. Huge, gross, cystic and nodular pimple. BUT my dermatologist said that it has to get better before it gets worse. Where my skin isn't being overran by grossness you can tell that it is clearing up and looking healthier. Tomorrow I will start my new dosage of 40 mg twice daily(the first month you start with 30 a day and then after that my dermo said they figure it out with your body weight) Side effects: pretty bad chapped lips, dry wrists and arms, also always in the bathroom cause I've been drink between a gallon and half to two gallons of water a day."
