Warfarin Therapy Patient Guide

🩸 Warfarin Therapy – A Practical Patient Guide (UK Primary Care Focus) Warfarin remains an important anticoagulant in UK practice, particularly for patients with atrial fibrillation, mechanical heart valves, and certain thromboembolic conditions. In this video, we explain warfarin therapy clearly and safely — covering what patients need to understand to reduce risk and stay within therapeutic range. 🔎 In this guide, we cover: • What warfarin is and how it works • Why INR monitoring is essential • Understanding target INR ranges • What affects INR (diet, alcohol, illness, medications) • Foods high in vitamin K and consistency advice • Common drug interactions (antibiotics, NSAIDs, amiodarone, herbal products) • Signs of bleeding and when to seek urgent help • Missed dose advice • Peri-operative considerations • Travel and anticoagulation cards ⚠️ Warfarin is highly effective but requires careful monitoring. Small changes in diet, illness, or medicines can significantly affect INR levels. This video is designed for: • Patients on warfarin • Family members and carers • GP practice teams • Pharmacists and prescribers 📌 Always follow advice from your anticoagulation clinic or GP.
