... taking antibiotics (generic bactrim) for acne. I have only taken 3 doses (it is meant to be taken 2 doses a day). I just realized that I want to tan to fix my farmer's tan in time for Vegas in a couple of weeks, but sulfamethoxazole makes you sensitive to sunlight. I would like to stop my medication, tan for a couple of days, and then begin my medication again (and finish it as prescribed). Would this be okay? I know you aren't supposed to stop antibiotics early, but I was wondering if it's much less of a problem if I've only taken 3 doses out of 60 (2/day for a month)
