Prevention of Bladder infection
"I was given this drug to prevent an infection because I passed a kidney stone.  After taking 2 doses, I ended up in the ER and was admitted to the hospital for 3 days!  I went to the ER because of 103.1 fever along with severe shakes and disorientation, I passed out twice in the ER. I began feeling better the next day, butI had to stay the 3 days because of a rapid heartbeat.  I am a very healthy 40 year old female, but this drug really did a number on me.  Will never take it again!"
