Probiotics that are lactobacillus rhamnosus-based and saccharomyces boulardii-based are usually the most effective for treating diarrhea. You can also get probiotics through fermented foods and drinks like yogurt, kefir, kombucha, kimchi, and sauerkraut.

Always ask your doctor first before you start taking another medication or supplement with antibiotics.

The most common antibiotics that cause diarrhea are cephalosporins, penicillins, and fluoroquinolones. Also talk to a doctor if your diarrhea doesn’t go away after you stop taking antibiotics.

In general, taking antibiotics with a meal usually helps to prevent an upset stomach.

Fatty and spicy foods are common triggers for an upset stomach.

Try sports drinks with electrolytes in addition to water.

Yogurt with live cultures can be an exception. The live cultures can help some people, but not all, digest better. Wheat flour may also upset your stomach while you are taking antibiotics.

It can be dangerous as well as uncomfortable to take alcohol with antibiotics.
