Ibrahem Mohamed El-Ameen: How Vitamin K Foods Affect Warfarin Therapy

Ibrahem Mohamed El-Ameen, 4-th year Pharmacy Student at Sphinx University, shared a post on LinkedIn:

Hidden Drug–Food Interactions – Part 3

Warfarin and Vitamin K Foods

‘Healthy eating’ can sometimes affect treatment

Today, a patient on Warfarin came with unstable INR results.

After reviewing his routine:

He recently started eating large amounts of spinach & broccoli daily as part of a ‘healthier lifestyle’.

What’s happening?

Foods rich in Vitamin K can reduce the effect of Warfarin

  • Decreased anticoagulation
  • INR becomes unstable

Possible Risks:

  • Thrombosis
  • Treatment failure
  • Increased risk of clot formation

Important Clinical Point:

  • The goal is not to completely avoid Vitamin K foods
  • The key is consistency in dietary habits

Because sudden increases or decreases can significantly affect INR.

Clinical Pearl:

Sometimes the issue isn’t the dose…

it’s a sudden lifestyle or diet change.”
