When you are diagnosed with a urinary tract infection and are givin antibiotics it is important that you take them everyday as directed until you finish them.
Lets say for example that you are given 7 pills for 7 days. And by the third day you feel completely fine as if you are healed. Well thats not always the case because it is very likely that your infection is still there. Lets say its just hiding lol. If you do not finish your medicine, and you still have the infection and not know it, your symptoms can come back. So the best thing for you to do is to just finish it as directed.
I have had hundreds of uti's and I know have a chronic painful bladder disease called Interstitial Cystitis. I have been givin a variety of different medications for my uti's etc. So I usually recognize the names of the medications givin to patients suffering with uti's etc. but i did not recognize this one so i looked it up on wikipedia here is the link:

It said it was discontinued in the first paragraph but i did not read on. If that medication did not help, you might consider asking your doctor about Bactrim or Levaquin. They are also antibiotics used for uti's and they had helped me in the past. But remember you have to FINISH your meds!!!!
Goodluck to you!
