"bactrim is absolutely amazing for acne.. i had seen 4 different dermatologists by the time i was 17. my face acne has been considered mild, but my acne on my back and chest is moderate to severe. they tried many oral and topical medications, creams/gels on me. nothing worked. then finally the last dermatologist i found, he prescribed me to bactrim 160/800. i can&#039;t remember how long i was on it the first time before it kicked in and started working, but i was on it for 2-3 years with absolutely perfect skin. i recently got pregnant and had to stop taking it. my acne slowly came back. now, i had my son a month ago. my acne is back and is awful. i was able to get prescribed bactrim again 2 weeks ago (apparently it&#039;s safe while nursing). i&#039;m still anxiously waiting for it to kick in.. but i have hope, and know it will. i highly recommend!!"
