Sulfamethoxazole / trimethoprim
"I've been on Bactrim and Aczone 7.5% for about a month now and my face is completely clear! I started noticing less breakouts the second week and by the end of the third week I had no new ones. I apply the Aczone in the morning before putting on makeup and then again at night after I wash my face. I'm not totally sure if it's the Bactrim or the Aczone that's clearing it up (maybe a combination?) but it's improved so much that even my bf mentioned that he noticed a difference this past week. I've also experienced no major side effects. My only concern is that once I slowly start to come off the medication, will the acne come back. Definitely give it a shot though if you've been struggling with acne and don't want to resort to Accutane!"
