If experiencing symptoms of biotin deficiency (hair loss, dermatitis, fatigue, or neurological symptoms), discuss biotin supplementation with your doctor. Routine supplementation may be considered in long-term users.
Why this interaction occurs
Valproate inhibits biotinidase, the enzyme responsible for recycling biotin from biocytin, and may also impair intestinal biotin absorption. This leads to functional biotin deficiency, which can cause neurological symptoms, alopecia, and skin changes, and may also reduce the activity of biotin-dependent carboxylase enzymes involved in energy metabolism.
Evidence
Evidence level: moderate.
