Sulfamethoxazole / trimethoprim
urinary tract infection
"This is the medicine of choice for urinary tract infections, so far as efficacy is concerned. I had rapid, steady improvement of my symptoms. However, please be aware that if you suffer from depression and anxiety it has the potential to exacerbate these conditions. I've also experienced increased headaches and mild-moderate nausea within hours of a dose (half-life= 1-4hrs). Stay well hydrated and maintain your urine output. The infection is bad enough by itself, without that potential complication!"
