Saccharomyces boulardii — Uses, Dosage, Side Effects & Safety

Drug class: Probiotic (Yeast-based)

Overview

Saccharomyces boulardii is a probiotic, which means it is a beneficial microorganism that helps maintain the natural balance of bacteria and yeast in the digestive system. It is a unique, non-pathogenic yeast that is used to prevent and treat various types of diarrhea, including those caused by antibiotics, infections, and travel. It may also be used to help manage symptoms of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) in some cases. Saccharomyces boulardii works by restoring the natural flora in the gut, inhibiting the growth of harmful bacteria, and supporting the immune system. It is not absorbed into the bloodstream and acts locally in the intestines. Most people tolerate it well, but it should be used with caution in people with weakened immune systems. Key points: Always follow your healthcare provider's instructions. Do not use Saccharomyces boulardii if you have a yeast allergy or are severely immunocompromised. If you develop symptoms such as high fever, persistent vomiting, or blood in your stool, seek medical attention immediately.
