Metronidazole
crohn's disease, acute
"Taking for possible c diff complicated by Crohn's disease.
For me the key to tolerating this drug is
Probiotics taken in morning at least one hour before first flagyl dose and secondly,  drink at least 8 oz of water with each dose.  The addition of probiotics has made a huge difference  in side affects particularly  nausea.   Water also important. I still feel some fatigue and occasional headache, but tolerable."
