Prophylactic Dosing of Vitamin K to Prevent Bleeding

Abstract

A vitamin K prophylactic regimen of 1 mg of vitamin K orally at birth followed by a daily oral dosage of either 25 or 150 µg fails to prevent VKDB in breastfed infants with still unrecognized BA. The data support 2 mg vitamin K IM at birth as prophylaxis against VKDB.
