Sulfamethoxazole / trimethoprim
"I just recently experienced my first urinary tract infection. I was on Cipro for 3 days and I thought it cleared up. But symptoms got worse within a couple days after I had stopped the Cipro. I was then prescribed sulfa... After 45 minutes within taking this pill I got terrible cramps, to the point where I couldn't even sit in a certain position or drive myself home. The second time, same thing. I have yet to take my third dose, but I'm honestly scared and annoyed that I'm probably going to have to go through the cramping again. Although, I must admit, after the first pill I feel my UTI is gone, but just to be safe I'm going to take it for one more day. I didn't throw up or anything, I did experience nausea but I made mint tea and that calmed my stomach."
