Warfarin, often referred to by its brand name Coumadin or Jantoven, is a commonly prescribed anticoagulant medication. It helps prevent dangerous blood clots that can lead to serious conditions like strokes or deep vein thrombosis (DVT). While it’s a lifesaving drug for many, patients on warfarin must take special precautions, especially when it comes to foot health. Here’s a guide to understanding warfarin and how it relates to at-risk foot care.
What Is Warfarin and Why Is It Prescribed?
Warfarin reduces your blood’s ability to form clots by blocking the action of vitamin K, which is essential for clotting. It is often prescribed to individuals with:
- Atrial fibrillation (irregular heart rhythm).
- History of blood clots in the legs (DVT) or lungs (pulmonary embolism).
- Artificial heart valves.
- Risk of stroke due to clotting disorders.
Why Does Warfarin Require Monitoring?
Patients taking warfarin must have regular blood tests to check their International Normalized Ratio (INR). This test measures how long it takes your blood to clot. The target INR range is usually between 2.0 and 3.0, but it may vary based on your condition. If your INR is too high, you’re at risk for serious bleeding; if it’s too low, you could develop dangerous clots.
Foot Health and Warfarin: Why It Matters
For people on warfarin, foot care becomes especially critical. Here’s why:
- Risk of Bleeding: Warfarin increases the risk of bleeding even with minor cuts, scrapes, or blisters. For individuals with diabetes or circulation issues, this risk is compounded because wounds on the feet may heal more slowly.
- At-Risk Skin: The skin on the feet is often subject to pressure, especially for those with bunions, calluses, or corns. Any break in the skin can lead to prolonged bleeding and a higher chance of infection.
- Nail Care Challenges: Trimming toenails can be tricky. If the skin around the nail is accidentally cut, it may bleed excessively. Patients with fungal nail infections or ingrown toenails are particularly vulnerable.

Tips for Foot Care While on Warfarin
- Protect Your Feet: Wear well-fitting shoes to prevent blisters and calluses.
- Inspect Daily: Check for cuts, sores, or redness. Use a mirror for hard-to-see areas.
- Moisturize: Keep your skin soft and prevent cracks, but avoid applying lotion between the toes.
- Avoid DIY Surgery: Never try to remove corns or calluses on your own.
- Seek Professional Help: Visit a podiatrist for nail trimming or if you notice signs of infection.
Diet and Warfarin
What you eat can affect how warfarin works. Foods high in vitamin K—like leafy greens—can interfere with the medication’s effectiveness. Maintain a consistent diet and consult your healthcare provider before making major dietary changes.
When to Call a Doctor
If you notice the following, seek medical help immediately:
- Unexplained swelling, redness, or pain in the foot.
- Persistent bleeding from a minor wound.
- Signs of infection, such as warmth, redness, or pus.
