bacterial infection
"Started taking Flagyl for bacterial vaginitis on Friday. Didn't start feeling side effects until late Saturday, where I experienced flu like symptoms. It is now Tuesday, and I can't wait until my last dose. I am taking 500mg every 12 hours for 7 days. I also have interstitial cystitis, which I think the medicine is irritating my bladder. Fatigue is the worst symptom so far, doesn't help when I work midnights and am already tired. No diarrhea though, and no yeast infection yet. When they prescribed it too me, I was not happy! I just tell myself the benefits outweigh the risks. I just hope my Interstitial Cystitis symptoms subside when this is done."
