Cephalexin
bacterial infection
"I was prescribed Keflex (Cephalexin) after having surgery to prevent infection, and wanted to add to the list of side effects.  They do not mention acid reflux, which I had every time I took the capsule (4 times a day, for 10 days). Also women need to take a probiotic while on this medication as it decreases natural flora and you can get yeast infection. I learned this the hard way by not eating enough yogurt while on this medication and not taking any probiotics. Just wanted to give a heads up and hopefully spare many women this highly uncomfortable experience."
