What Are Blood Thinners and Why Are They Prescribed?

Blood thinners are medications commonly prescribed to reduce the risk of dangerous blood clots. Despite their name, these drugs do not actually thin the blood. Instead, they work by preventing clots from forming or by stopping existing clots from growing larger, helping to protect against serious and potentially life-threatening conditions.

There are two primary types of blood thinners used in medical treatment.
Anticoagulants slow down the body’s clot-forming process. Common examples include warfarin (Coumadin) and newer medications known as direct oral anticoagulants (DOACs), such as apixaban (Eliquis), rivaroxaban (Xarelto), and dabigatran (Pradaxa).
Antiplatelet medications prevent blood platelets from sticking together. Aspirin at low doses is the most widely known, along with clopidogrel (Plavix).

Doctors prescribe blood thinners for conditions such as atrial fibrillation, deep vein thrombosis, pulmonary embolism, after heart valve surgery, and following a heart attack to help prevent future cardiovascular events.

The Primary Long-Term Risk of Blood Thinners: Increased Bleeding

The most significant long-term risk associated with blood thinners is an increased tendency to bleed. Because these medications interfere with clot formation, the body may take longer to stop bleeding after an injury. While minor bleeding is common, major bleeding events are the primary concern with long-term use.

Many people experience mild bleeding symptoms such as easy bruising, minor nosebleeds, bleeding gums after brushing teeth, or small cuts that take longer to heal. These effects are usually manageable but should still be reported to a healthcare provider.

More serious bleeding events require immediate medical attention. Gastrointestinal bleeding can occur in the stomach or intestines and may present as vomiting blood, material that looks like coffee grounds, bright red blood in the stool, or black, tar-like stools.
Intracranial hemorrhage, or bleeding in the brain, is the most dangerous complication and can be life-threatening. Warning signs include a sudden severe headache, vision changes, weakness or numbness on one side of the body, confusion, or difficulty speaking.

Emergency medical help should be sought immediately if any of these symptoms occur.

Other Long-Term Health Considerations When Taking Blood Thinners

Long-term blood thinner use requires careful monitoring due to potential interactions and effects on overall health.

Many medications, supplements, and foods can interfere with blood thinners. Pain relievers such as ibuprofen or naproxen can significantly increase the risk of bleeding, especially in the stomach. Certain herbal supplements, including ginkgo biloba, garlic, ginseng, and St. John’s Wort, may also affect clotting.
For patients taking warfarin, maintaining a consistent intake of vitamin K is essential, as sudden dietary changes can reduce or increase the medication’s effectiveness.

Kidney function is another important consideration, particularly for newer anticoagulants like Eliquis and Xarelto, which are partially cleared through the kidneys. Patients with kidney disease may require dosage adjustments and regular blood tests to ensure safe use.

Some studies suggest a possible link between long-term warfarin use and reduced bone density. While this risk appears to be lower with newer anticoagulants, patients with osteoporosis risk factors should discuss bone health with their doctor.

Living Safely While Taking Blood Thinners

For most patients, the benefits of blood thinners far outweigh the risks when managed properly. Preventing strokes, pulmonary embolism, and other serious complications is the primary goal of long-term therapy.

Patients should maintain regular communication with their healthcare provider, attend all monitoring appointments, and report any falls, injuries, or unusual bleeding. It is important that all doctors, dentists, and pharmacists are aware of blood thinner use. Wearing a medical alert bracelet can be lifesaving in emergencies. Extra caution should be taken during daily activities to reduce the risk of injury, and using soft toothbrushes or electric razors can help prevent minor bleeding.

Frequently Asked Questions About Blood Thinners

Alcohol consumption should be discussed with a doctor, as heavy drinking can increase bleeding risk and interfere with certain medications, especially warfarin.
For minor cuts, applying firm pressure with a clean cloth for several minutes is usually sufficient. Medical attention is necessary if bleeding does not stop.
There are no proven natural alternatives that can safely replace prescription blood thinners for serious conditions such as atrial fibrillation or deep vein thrombosis. Patients should never stop or replace prescribed medication without medical guidance.
