Can Bactrim Make The Birth Control Pill Less Effective?
I ve been taking birth control for about six months now. Last week, while on the sugar pills week, I started taking Bactrim because of a UTI. I finished the last sugar pill and the last antibiotic pill on the same day. Is my birth control now less effective? I always use other methods of birth control as well, but it is still something that concerns me. Thank you for your time.

hello dear.
understand your concern.
bactrim have some effects on pills like it increase chance of failure of pills which is 0.5%.
i think you don't worry because you take it with sugar pills,& you said ,you always use other method also,then not to worried at all.
so be relaxed,it cant affect your birth control.
hope this will help you.
best regards.
