Sulfamethoxazole / trimethoprim
"I went to the ER for pain in my lower back & my stomach. The Dr said I had an UTI which I didn't think that was the case cause I didn't have the symptoms of a UTI. Anyways, I started using the pills (Antibiotics) & about an hour of using it I felt nauseas, dizzy & started vomiting,itch all over my body & also I lost my appetite. I throw the pills away, I don't recommend them at all. I never have been allergic to any medication in my life."
