urinary tract infection
"First time prescribed Bactrim for mild UTI. Second day I had flu like symptoms. After day 4 I was feeling so poorly I went to ER where I was told just flu and to rest and to finish Bactrim so it will clear up UTI. Day 5 fever of 105, rushed to hospital where I passed out. Completely dehydrated and organs where showing signs of sepsis. I was in ICU unit for 3 days. The diagnosis was “allergy to sulfa”. However, that’s not really an allergic response. I think it causes the body to dehydrate faster than normal, and my actual problem was intense dehydration. Bactrim was banned in UK after a number people died. I’ll never take it again."
