prevention of bladder infection
"I started taking Bactrim on a Tuesday. By Wednesday I was depressed and had terrible knots in my stomach. I was going to bathroom almost every hours and had hives all day and night. Thursday, I felt a lot better and my symptoms were mostly relieved as well. I thought it worth the hives and frequent bathroom breaks. On Friday my lips, gums, tongue and face were all swollen. I didn't think it was the medication at all. Doc's nurse called to tell me that my culture came back and that they are switching my medicine.

When I changed the medicine on Saturday I had sores in my mouth along with the swollen gums. I made a dental appointment thinking that it is due to an immunization problem, by Sunday I called my doctor and learnt that I developed allergies."
