bladder infection
"I took the 200 mg strength and was given 16 tablets. On the morning in which I took the very last dose I came out in the most horrendous rash I have EVER experienced and have told I must NEVER take that drug again.  The rash - over a period of about 3 hours - spread over my entire body, including my face.  I was hot and itchy beyond belief.  My doctor was absolutely shocked as she said that any reaction usually appears after taking just a few tablets. I'm in U.K. so some questions are not relevant to me."
