Chronic mineral oil use can reduce absorption of phytonadione and other fat-soluble vitamins, which may lead to hypoprothrombinemia and bleeding in susceptible patients, such as those on anticoagulants or with poor intake.
What this interaction means in plain words
Mineral oil 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.
Mineral oil belongs to Gastrointestinal Tract; Vitamin k1 belongs to Cardiovascular.
Why it happens
