bladder infection
"This medication was prescribed to me for a bladder infection. After I took the second dose I woke in the middle of the night with the worst headache I've ever had in my whole life! I literally thought I might have to go into see the doctor. After it subsided I read all the reviews I could about this medication and it side effects.  It seemed as though it was starting to work for my bladder infection but the terrible side effects were not worth it. I called my doctor and they prescribed Cipro instead. It took care of my infection with no side effects."
