Xifaxan - can you eat yogurt with probiotics in it while on this Rx?

No, yogurt will not counteract the purpose of the antibiotic. The problem with antibiotics, which I am sure you already know, is that they destroy bacteria. They destroy all bacteria even the good ones that you need in your stomach that assist with digestion and immune responses. The yogurt is a good idea, but I would actually purchase a probiotic that breaks down in the stomach and the lower intestine. If you eat the yogurt right after or before taking the antibiotic the antibiotic will cancel out the benefits of the yogurt or other probiotic. You should take either 2 hours before or 2 hours after. I usually don't take the probiotic until after I finish the antibiotic because it is too frustrating to figure out when to actually take it. If you are prone to digestive problems or yeast infections after taking an antibiotic you can also ask the prescribing physician to prescribe Diflucan, which kills off yeast infections that flare up due to the intestinal imbalance caused by the antibiotic. I hope this helps. Good Luck!
