- To prevent the blood clot from becoming larger.
- To prevent the blood clot from traveling to the lungs (pulmonary embolism).
- To prevent post-thrombotic syndrome, a condition that can cause pain, sores, and swelling of the affected leg.
- To prevent blood clots from returning.
DVT is usually treated with anticoagulant medicines. These medicines are often called blood thinners, but they do not actually thin the blood. They prevent blood clots by increasing the time it takes a blood clot to form. Also, anticoagulants help prevent existing blood clots from becoming larger.
Other treatments may be used in the hospital for some people. These treatments include thrombolytic medicine or vena cava filters. These treatments are not common. They might be used for people who are at risk for serious problems from DVT.
Your doctor may also recommend self-care to relieve symptoms and prevent complications. This care includes:
- Elevating your leg.
- Wearing compression stockings.
