Biotin Administration Guidelines

Introduction to Biotin Administration

The European Society for Clinical Nutrition and Metabolism (ESPEN) establishes a clear treatment algorithm based on intestinal function, recommending oral biotin for rapid replenishment in biotin deficiency, with IV biotin reserved for parenteral nutrition-dependent patients 1, 2, 3

The ESPEN guidelines recommend oral biotin as the first-line treatment for biotin deficiency, with malabsorption/short bowel cases requiring increased oral doses to 10 mg/day 1, 2
IV biotin is reserved exclusively for parenteral nutrition (PN)-dependent patients requiring up to 200 mg/day for 2-3 weeks 1, 2, 3
The American Society for Parenteral and Enteral Nutrition does not mention intramuscular biotin administration in its guidelines, in contrast to other micronutrients like vitamin D, where IM routes are explicitly discussed 6

The ESPEN guidelines recommend a standard maintenance dose of at least 30 mcg/day in 1500 kcal (Grade B recommendation) for enteral nutrition 1, 3
For parenteral nutrition, the recommended dose is 60 mcg/day (Grade B recommendation) 1, 2, 3
The treatment of deficiency recommends oral biotin at 10 mg/day for malabsorption/short bowel, and IV biotin up to 200 mg/day for 2-3 weeks for PN-dependent patients 1, 2, 7

Pregnancy may require up to 300 mcg/day based on metabolic markers, while breastfeeding requires at least 35 mcg/day orally 1, 2, 8
Renal replacement therapy may require additional amounts of biotin 4

No upper limit for biotin intake has been established, and no adverse effects have been reported with oral or IV doses up to 5 mg/day for prolonged periods 1, 7, 9
