"i&#039;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&#039;m off and my skin has remained clear (minus very small pimples here and there)."
