Sulfamethoxazole / trimethoprim
urinary tract infection
"The medicine helped me greatly. It took a few days to kick in, though. I didn't experience any nausea/vomiting that seems to be the most commonly-experienced side effects, but I did experience some constipation and headache. I also felt what I'd describe as being "out of it" and "spacey". I said and did the most air-headed things. Make sure you take Acidophilus when taking this medicine."
