Antibiotic treatment disturbs the balance of the intestinal microbiota and predisposes to
antibiotic associated diarrhea. Previous studies have shown that the risk of developing
diarrhea during a course of antibiotics may be reduced by simultaneous consumption of
probiotics. The aim of the present study is to assess the effect of a probiotic formula
containing four strains on reducing the risk of antibiotic associated diarrhea.
