I just have 3 days taken bactrim (sulfamethoxazole and trimethoprim) 2 times a day and I still going to the bathroom like 6 times in those 3 days what can I do please?

Not getting better? You should call your doctor and let them know. Sometimes, the bacteria that cause bladder infections can be resistant to the antibiotics doctors give. We like to send what's called a "urine culture", to know for sure what medicines kill the bacteria. If your symptoms aren't improving, the bacteria might be resistent to Bactrim (sulfamethoxazole and trimethoprim) and you may need a different one. Good luck!
