Lactobacillus (Lactobacillus species (various strains)) — Uses, Dosage, Side Effects & Safety

Drug class: Digestive & Gastrointestinal

Overview

Lactobacillus is a type of probiotic, which means it is a live microorganism that can provide health benefits when taken in adequate amounts. It is commonly used to help restore the natural balance of bacteria in the gut, especially after antibiotic use or during episodes of diarrhea. Lactobacillus works by colonizing the intestines and producing substances that inhibit the growth of harmful bacteria. It may also help support the immune system and improve digestion. Key points for patients: Lactobacillus is generally considered safe for most people, but it should be used with caution in those with weakened immune systems. It is available in many over-the-counter forms and is often used for digestive health, prevention of antibiotic-associated diarrhea, and support of general gut health.
