bladder infection
"I have a double whammy: I have interstitial cystitis (which feels like a constant bladder infection), and on top of that I'm prone to actual bladder infections. I've learned to be able to tell the difference between a bladder infection and a cystitis flare up. I have A LOT of drug allergies and can not take sulfa drugs or Cipro, which are commonly prescribed for bladder infections. Keflex has been the ONLY antibiotic that I can take that doesn't give me any side effects AND gets rid of the infection. It's saved my bacon on numerous occasions. I also prophylactically take Acidophilus orally and douche with plain yogurt to avoid yeast infections. It all works like a charm. I have NEVER had a bad side effect from Keflex."
