prevention of bladder infection
"I took this med once before and had the same symptoms so I don't think the first time was a fluke.  After taking just one pill, within a few hours, I was nauseous to the point I could not lay down.  My head started to hurt and then within in six hours I had body aches all over.  I also developed a cough, and it was hard to breathe.  It has been over 14 hours, I am just now starting to feel a little better.  This medicine is awful.  Don't take it."
