Vitamin K deficiency bleeding is a haemorrhagic condition that puts newborn infants at increased risk of bleeding during the first six months of life. The consequences can be disastrous, including lifelong disabling neurological sequelae or death, and can be prevented by a single intramuscular injection of vitamin K at birth. This is regularly cited as the prophylaxis gold standard for its simplicity of administration and efficacy when patients have cholestasis, although repeated oral vitamin K doses have comparable efficacy. ^1,2 .
