"This works fine for me, I'm allergic to most of the antibiotics out there but not this one thankfully.  I get uti's frequently, because I always have to be cultured, sometimes that waiting period helps the  thing really get going.  Normally its a 10 day course... I do not get headaches or any of the side effects others have had.  Everybody's body is different, the only way you'll know how you will react is to take it yourself."
