urinary tract infection
"After I got home and had taken about 4 of these I had loss of appetite, and had a headache. I looked at the papers from the pharmacy and I seen it said sulphamethazole! I called my doctor in a panic since it is listed in my allergies. I haven't had an allergic reaction, but my dad and moms side have. I finished out the antibiotic and have been fine. I did notice on Monday, which was my last dose, that I was feeling really queezy and had a headache. But no hives. Also This did some weird things while on it. I felt sick, and wasn't hungry, plus gave me a little anxiety. I will go back in a few days to make sure it is all cleared up. I took it for five days twice a day. I do however feel tons better."
