Bleeding Risks with New Blood Thinners: What You Need to Know
Published: Aug 24, 2024
Blood thinners are lifesavers, preventing dangerous clots. But they come with a trade-off: an increased risk of bleeding. Understanding this risk is crucial for anyone taking these medications.
The Bleeding Basics
All blood thinners, including newer direct oral anticoagulants (DOACs), increase the risk of bleeding. This can range from minor bruising to more serious internal bleeding. The good news? DOACs generally have a lower risk of the most dangerous type of bleeding - in the brain - compared to older drugs like warfarin.
Who's at Higher Risk?
Certain factors can increase your bleeding risk on blood thinners. These include being over 75, having kidney problems, a history of stomach ulcers, or taking other medications that affect blood clotting (like aspirin). It's crucial to discuss all your medical conditions and medications with your doctor when considering blood thinners.
Signs to Watch For
While on blood thinners, it's important to be aware of bleeding signs. These can include unusual bruising, nosebleeds that won't stop, blood in urine or stools, or severe headaches. If you experience these symptoms, contact your healthcare provider immediately. Remember, prompt attention to bleeding can prevent more serious complications.
Minimizing the Risk
There are steps you can take to reduce your bleeding risk. Take your medication exactly as prescribed. Avoid activities with a high risk of injury. Be cautious with over-the-counter pain relievers, as some can increase bleeding risk. Regular check-ups with your doctor are important to monitor your health and adjust your treatment if needed.
