My daughter took it for 1 1/2 years and never had one problem. It helped tremendously. It's not good to take any antibiotic long term. Some people have serious reactions to bactrim but they happen right away. I agree it would be great if your bcp controlled you and you didn't need the Bactrim any more.

I'm on my 3rd month on Bactrim as well and I haven't had any side effects at all, and it's helped my face clear up alot, good stuff!

I took Bactrim for about 1 and 1/2 years. I then went through a period where my skin broke out very badly for about two months and went back to Bactrim for about another 8 months. I never had any bad side effects; atleast not visible, or so much physically. However something to remember is that your body becomes dependant whenever you take an antibiotic for such a long time. Basically the bactrim will not only kill the bacteria but also your white blood cells and other friendly bacteria. However it definetly helped clear up my skin almost amazingly while I was taking it.
