Sulfamethoxazole / trimethoprim
"I started taking this medicine for a UTI that was awful. This is my first UTI and I'm 18. I'm on day 3 now and it seems like the side effects from the pills are way worse than the actual UTI. I'm reading all the other reviews and the medicine has made me nauseous but it's also giving me really bad abdominal pain and sharp pain in my ribs along with feeling really dizzy and hot( especially at work) hoping It doesn't get worse as I take it"
