What Is Florastor?

Florastor (Saccharomyces boulardii) is a prescription-strength probiotic used to manage diarrhea and support gut health during and after antibiotic use or gastrointestinal illness. It works by replenishing beneficial microorganisms in the intestinal tract, inhibiting pathogen growth, and supporting the integrity of the intestinal mucosa. With the right dosing and ongoing support, many people experience meaningful relief from diarrhea and improved digestive balance.

Is Online Florastor Treatment Right for You?

Florastor may be appropriate for adults experiencing diarrhea related to antibiotic use, traveler's diarrhea, or acute gastrointestinal illness. A licensed Doctronic physician will review your symptoms, medical history, and current medications to determine whether Florastor is the right choice for you.

Because gut health is closely tied to your overall gastrointestinal and immune history, your provider will also consider any history of inflammatory bowel conditions, recent antibiotic courses, immune status, or other factors that may affect how your digestive system responds to probiotic therapy.

Frequently asked questions

Florastor contains Saccharomyces boulardii, a beneficial yeast that helps restore normal intestinal flora. It is commonly used to prevent and treat diarrhea associated with antibiotic use, traveler's diarrhea, and acute gastrointestinal illness.

Saccharomyces boulardii works by repopulating the gut with beneficial microorganisms, inhibiting the growth of harmful pathogens, reducing intestinal inflammation, and supporting the protective mucous lining of the intestinal tract.

Many people notice improvement in stool consistency and frequency within 2 to 3 days of starting Florastor, though results can vary depending on the underlying cause of diarrhea and individual factors.

Yes. Florastor is frequently used alongside antibiotics specifically because it helps prevent antibiotic-associated diarrhea. It is best to separate the doses by at least 2 hours when possible, and your physician can advise on the appropriate timing.

Florastor is generally not recommended for people with severely compromised immune systems, those with central venous catheters, or individuals with a known allergy to yeast or any component of the formulation. Your Doctronic physician will review your health history before recommending it.

Florastor is generally well tolerated. The most commonly reported side effects are mild gastrointestinal symptoms such as gas or bloating. Serious adverse effects are rare but can occur in immunocompromised individuals.
