Doctors have several ways to treat a deep-vein thrombosis (DVT). The most common treatment is a drug called a blood thinner. Blood thinners are also called anticoagulants.
These drugs stop the clot from getting bigger. They also help prevent it from breaking off and moving to the lungs. And they prevent other clots from forming.
Blood thinners don’t break down the clot itself. The body does that over time.
