"I took Bactrim 2x's a day for ten days (should have been 14 days). The first ten days, no problems at all. On the night of the tenth day I itched all night and woke up with a rash all over my body. Dr. said to stop taking the Bactrim. He gave me two doses of steriods (40mg a day for 2 days) and benedryl. I quit taking the Benedryl on day 3 because the rash had cleared up. The next day it began to spread again. I have been taking Benedrly for seven days now and when I dont take it my cheeks get very "rosy". I would love to know how long this stuff stays in your system. Even the mfg. says you can have a reaction up to 2 months later. Thats really scary!"
