Dosing Guidelines
- Higher doses of 2.5 × 10⁹ to 4 × 10¹¹ CFU per day are used in critically ill patients, as recommended by Critical Care and Praxis Medical Insights 3, 1, 4
- Preterm infants can be given a combination of Lactobacillus and Bifidobacterium species at doses appropriate for weight, typically 10⁷-10⁹ CFU/day, as stated in Gastroenterology 5
Duration of Treatment
- For antibiotic-associated diarrhea prevention, probiotics should be continued throughout the antibiotic course and for 5-7 days after completion, as recommended by Gut Microbes 6, 7

Important Clinical Caveats
- Probiotics are contraindicated in immunocompromised patients due to bacteremia risk, as stated in Praxis Medical Insights 4
- Multi-strain formulations may be more effective than single strains for certain conditions, as recommended by Gut Microbes and Praxis Medical Insights 7, 4
