Clinical monograph: boulardi
Boulardi, commonly referred to as Saccharomyces boulardii, is a probiotic yeast strain that is used to support gastrointestinal health. It is known for its ability to restore the natural flora of the gut and is often utilized in the management of various gastrointestinal disorders. Saccharomyces boulardii is particularly noted for its role in the prevention and treatment of antibiotic-associated diarrhea and for its potential benefits in managing inflammatory bowel diseases.
Indications
- Antibiotic-associated diarrhea
- Clostridium difficile infection
- Inflammatory bowel disease
- Irritable bowel syndrome
- Traveler's diarrhea
Dosage
Children: Refer to product-specific guidelines or consult a healthcare professional for appropriate dosing.
Adults: Refer to product-specific guidelines or consult a healthcare professional for appropriate dosing.
Mechanism of action
Saccharomyces boulardii exerts its beneficial effects through multiple mechanisms. It enhances the intestinal barrier function, promoting the integrity of the gut mucosa. It also modulates immune responses by stimulating the production of secretory immunoglobulin A (sIgA) and other immune mediators. Additionally, it produces short-chain fatty acids and other metabolites that can inhibit pathogenic bacteria and promote the growth of beneficial gut flora.
Pharmacodynamics
The pharmacodynamics of Saccharomyces boulardii involve its ability to adhere to the intestinal mucosa, thereby preventing the adhesion of pathogenic microorganisms. It also influences the gut microbiota composition and acts to reduce inflammation within the gastrointestinal tract. The probiotic properties contribute to the maintenance of intestinal health and the prevention of dysbiosis.
Pharmacokinetics
Saccharomyces boulardii is not absorbed systemically; instead, it acts locally within the gastrointestinal tract. Following oral administration, it survives the acidic environment of the stomach and reaches the intestines where it colonizes temporarily. The yeast is eventually excreted in the feces, and its effects can be observed shortly after administration, generally within 1 to 3 days.
Adverse effects
- Bloating
- Gas
- Constipation
- Allergic reactions
Precautions
- Use with caution in immunocompromised patients
- Patients with severe underlying health conditions should consult a healthcare provider before use
Pregnancy
Generally considered safe, but consult a healthcare provider before use.
Breast-feeding
Generally considered safe, but consult a healthcare provider before use.
Storage

Clinical monograph: saccharomyces
Saccharomyces, commonly known as brewer's or baker's yeast, is a genus of fungi used for its fermentative properties. It is primarily utilized in the production of alcoholic beverages, baking, and as a dietary supplement due to its probiotic effects. Saccharomyces boulardii, a specific strain, is recognized for its beneficial effects on gastrointestinal health.
Indications
- Antibiotic-associated diarrhea
- Acute infectious diarrhea
- Chronic diarrhea in conditions like irritable bowel syndrome
- Maintenance of gut flora during antibiotic therapy
- Prevention of traveler's diarrhea
Dosage
Children: Refer to specific product guidelines for paediatric dosages, as they may vary depending on the formulation and age of the child.
Adults: Refer to specific product guidelines for recommended adult dosages, as they may vary depending on the formulation.
Mechanism of action
Saccharomyces boulardii exerts its effects by promoting gut health through various mechanisms. It enhances the intestinal barrier function, modulates local immune responses, and inhibits the growth of pathogenic bacteria. It also produces short-chain fatty acids and aids in the maintenance of gut microbiota balance, which can help in reducing diarrhea and improving gut health.
Pharmacodynamics
The pharmacodynamics of Saccharomyces involve its ability to adhere to intestinal mucosa, which helps in restoring the normal flora of the gut. It has been shown to reduce the duration and severity of diarrhea, particularly in cases of antibiotic-associated diarrhea and infectious diarrhea. Additionally, it may enhance the absorption of nutrients and support the immune system.
Pharmacokinetics
Saccharomyces boulardii is generally not absorbed systemically; instead, it acts locally in the gastrointestinal tract. It survives passage through the stomach and colonizes the intestines, where it exerts its beneficial effects. The viability of Saccharomyces is influenced by factors such as pH, temperature, and the presence of other gastrointestinal microorganisms. Its effects are typically observed within a few days of administration.
Adverse effects
- Gastrointestinal upset
- Bloating
- Gas
- Diarrhea
Interactions
- May interact with antifungal medications
- Potential interactions with immunosuppressive drugs
Precautions
- Caution in patients with compromised immune systems
- Use with caution in patients with a history of yeast allergies
