Urinary Tract Infection
"Avoid this medication AT ALL COSTS! Although it may not cause side effects for some, I was one of the many unlucky ones who experienced terrible problems. I have never had a problem with any antibiotics except Sulfa drugs before, but this medication left me nauseated, vomiting, dealing with chills for hours, shaking so hard I couldn&#039;t move, and with a terrible headache. I haven&#039;t taken a dose in 12 hours (with my doctor&#039;s suggestion), and the headache is just now going away. It took about 8 hours for the shaking to stop. At one point it was so bad that I thought I was going to have to go to the ER. I was only two doses in, as well. This was worse than the Sulfa reaction I had!"
