Sulfamethoxazole / trimethoprim
"Gave two stars because it did actually clear up my uti, I think. No more burning or cloudy urine. The side effects were awful. Not only did I have extreme nausea, headaches, chills, hot flashes, insomnia, constipation, shakiness, and racing heart but it also came with emotional/mental side effects which I've never experienced with a prescription before. I feel super anxious and a bit paranoid, to the point of keeping me up at night. I'm on my 4th day of 7 day dose, but today will be my last on this medicine. I've decided I'd rather risk getting the UTI again than deal with these side effects any longer, if it comes back I'll definitely be asking my doctor for a different antibiotic. And I took it exactly as directed, with plenty of water."
