Acne
"I was put on Bactrim DS twice a day for about 6 weeks. This was after being on doxycycline for about 4 months with disappointing results. My acne was cystic and mainly distributed across my back, neck, shoulders, and chest. This outbreak of acne started some time after I stopped hormonal oral BC and switched to Paragard. It also coincided with the start of treatment with lithium for bipolar disorder. The latter can exacerbate acne in those that are susceptible. Despite quitting it, the disaster continued. My derm put me on Bactrim DS twice a day for 6 weeks and to my amazement - this finally did the trick. My skin completely cleared! Highly recommended. No side effects but I took a probiotic with it. My skin has stayed mostly clear since."
