Question:
When is the best time to take probiotics to prevent diarrhea from antibiotics - before, during, or after the course of antibiotic treatment?

Answer:
As discussed in more detail in the Probiotic Supplements Review, probiotics can be taken starting the first day of oral antibiotic treatment and continued for 2 weeks after the completion of antibiotic therapy. It may be advisable to take probiotics and antibiotics at least 2 hours apart to reduce the possibility of the antibiotic killing the probiotic organisms. For more details about the types and amounts of organisms which have been shown helpful in reducing the risk of antibiotic-related diarrhea see the Probiotic Supplements Review >>

Note: If diarrhea occurs when taking an antibiotic and persists for several days, see a physician. Severe cases of C. difficile-associated diarrhea, for example, can be life-threatening.

Karen, can you tell us what brand and strength you took?

I took "Vitacost Probiotic 15-35" which I had been taking for months before the incident, and I still take it. I have no financial interest in giving out the name of this product.

I was hospitalized for 5 days on IV vancomycin for cellulitis that went into sepsis. I took probiotics with me to the hospital and swallowed 2 capsules every 2-4 hours the entire time I was there. Contrary to the severe diarrhea that one could get from this heavy-duty IV antibiotic, I actually got constipated. I never got diarrhea from the antibiotic. So I think the probiotics definitely worked.
