Sulfamethoxazole / trimethoprim
"I got my UTI early. When I first took the medicine I got a light headache but I didn't think nothing of it. After taking the second pill, my whole body started aching, hot flashes, fever, everything. It was so bad that I wasn't about to take care of my child. My husband tried to help but there was nothing he could do. I stayed up until 4 am because of the tossing and turning to get comfortable. This medicine needs to go."
