Summary

Ketorolac inhibits platelet function and increases bleeding risk, which may work against the aim of phytonadione in bleeding or coagulopathy. Systemic exposure from the nasal form is lower than oral or injected ketorolac but still present.

What this interaction means in plain words

Ketorolac intranasal and Vitamin k1 can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Moderate

Why it happens

Ketorolac's reversible COX-1 inhibition impairs platelet aggregation, a pharmacodynamic effect not corrected by vitamin K.

What to do

Avoid ketorolac in patients with active bleeding or vitamin K-responsive coagulopathy; choose a non-NSAID analgesic.
