Sulfamethoxazole / trimethoprim
acne
"I've had cystic acne on/off for four years. It would come and go where my skin would be horrible my acne and cysts all over then clear up for a few months. I had a bad breakout and took Doryx which made my acne worse. I switched to bactrim and within 1 month, my breakouts stopped and my larger cysts were going down.



About 3 months later, I'm off and my skin has remained clear (minus very small pimples here and there)."
