Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin K is scientifically justified for use in certain cases of nosebleeds (epistaxis), though its effectiveness is specific to underlying causes related to coagulation. Vitamin K is essential for the synthesis of several clotting factors in the liver, including factors II, VII, IX, and X. Deficiency of vitamin K impairs blood clotting and increases the risk of spontaneous bleeding, including from the nasal mucosa. Medical literature and clinical guidelines note that vitamin K supplementation is indicated in patients with bleeding tendencies due to vitamin K deficiency, which may be caused by malabsorption, certain medications (like warfarin), liver disease, or dietary insufficiency.

However, most nosebleeds are not caused by vitamin K deficiency but by local trauma, dry air, or underlying vascular fragility. In these typical cases, vitamin K supplementation does not provide benefit. Scientific evidence supporting routine use of vitamin K for nosebleeds is therefore limited; it is reserved for cases where laboratory evidence demonstrates a deficiency or coagulopathy. Topical vitamin K preparations have very limited and inconsistent data for local application in epistaxis, and systemic supplementation is only indicated in documented deficiency states.

In summary, while there is clear scientific rationale for vitamin K use in specific cases of bleeding due to deficiency, there is little evidence to support its routine use for general nosebleeds. The overall evidence rating for this indication is 2 out of 5, reflecting its effectiveness in a defined subset of patients, but not for the broader population with nosebleeds.
