A common side effect of antibiotics is diarrhea , which may be caused by the elimination of beneficial bacteria normally found in the colon. A nonpathogenic yeast known as Saccharomyces boulardii has been shown in two double-blind studies to decrease frequency of diarrhea in people taking amoxicillin as well as other penicillin-type drugs compared to placebo.^{26 , 27} There were overall few people in these studies using amoxicillin specifically, so there is no definitive proof that Saccharomyces boulardii will be beneficial for everyone when it is combined with amoxicillin. The studies used 1 gram of Saccharomyces boulardii per day.

A separate double-blind study found that taking a combination of Lactobacillus acidophilus and Lactobacillus bulgaricus, two normal gut bacteria, with amoxicillin did not protect children from developing diarrhea.²⁸ The authors of the study point out some problems such as the parents’ inability to consistently define diarrhea. However, at this time, it is unknown if lactobacillus products will reduce diarrhea due to amoxicillin.

Controlled studies have shown that taking other probiotic microorganisms—such as Lactobacillus casei or Bifidobacterium longum—also helps prevent antibiotic-induced diarrhea.²⁹

The diarrhea experienced by some people who take antibiotics also might be due to an overgrowth of the bacterium Clostridium difficile, which causes a disease known as pseudomembranous colitis. Controlled studies have shown that supplementation with harmless yeast—such as Saccharomyces boulardii ³⁰ or Saccharomyces cerevisiae (baker’s or brewer’s yeast)³¹—helps prevent recurrence of this infection. In one study, taking 500 mg of Saccharomyces boulardii twice daily enhanced the effectiveness of the antibiotic vancomycin in preventing recurrent clostridium infection.³² Therefore, people taking antibiotics who later develop diarrhea might benefit from supplementing with saccharomyces organisms.

Treatment with antibiotics also commonly leads to an overgrowth of yeast (Candida albicans) in the vagina ( candida vaginitis ) and the intestines (sometimes referred to as “dysbiosis”). Controlled studies have shown that Lactobacillus acidophilus might prevent candida vaginitis.³³

Controlled studies have shown that supplementation with harmless yeast—such as Saccharomyces boulardii ³³⁴ or Saccharomyces cerevisiae (baker’s or brewer’s yeast)³³⁵—helps prevent recurrence of this infection. In one study, taking 500 mg of Saccharomyces boulardii twice daily enhanced the effectiveness of the antibiotic vancomycin in preventing recurrent clostridium infection.³³⁶ Therefore, people taking antibiotics who later develop diarrhea might benefit from supplementing with saccharomyces organisms.

Treatment with antibiotics also commonly leads to an overgrowth of yeast (Candida albicans) in the vagina ( candida vaginitis ) and the intestines (sometimes referred to as “dysbiosis”). Controlled studies have shown that Lactobacillus acidophilus might prevent candida vaginitis.³³⁷

A common side effect of antibiotics is diarrhea , which may be caused by the elimination of beneficial bacteria normally found in the colon. Controlled studies have shown that taking probiotic microorganisms—such as Lactobacillus casei, Lactobacillus acidophilus, Bifidobacterium longum, or Saccharomyces boulardii—helps prevent antibiotic-induced diarrhea.³³⁸

The diarrhea experienced by some people who take antibiotics also might be due to an overgrowth of the bacterium Clostridium difficile, which causes a disease known as pseudomembranous colitis. Controlled studies have shown that supplementation with harmless yeast—such as Saccharomyces boulardii ³³⁹ or Saccharomyces cerevisiae (baker’s or brewer’s yeast)³⁴⁰—helps prevent recurrence of this infection. In one study, taking 500 mg of Saccharomyces boulardii twice daily enhanced the effectiveness of the antibiotic vancomycin in preventing recurrent clostridium infection.³⁴¹ Therefore, people taking antibiotics who later develop diarrhea might benefit from supplementing with saccharomyces organisms.
