No: Probiotics will not make your antibiotic less effective, but they might protect your gut from having problems like diarrhea. Antibiotics can kill off your natural gut bacterial flora, allowing infectious bacteria to take over. Probiotics can re-establish normal bowel flora so that this is less likely to happen.
