Blood thinners, also called anticoagulants and anti-platelet drugs, are medicines used to prevent blood clots from forming. Despite being called blood thinners, they do not actually thin the blood, they just help make it less likely for blood clots to form.
Blood thinners may be prescribed for people who had a blood clot to prevent it from worsening, or to prevent a new blood clot from forming in people who have a high risk of developing a blood clot.
Blood thinners are commonly prescribed to people who have conditions such as:
- Atrial fibrillation (AFib)
- Blood vessel conditions, such as deep vein thrombosis (DVT) or pulmonary embolism (PE)
- Heart disease
- Heart valve replacement
- Congenital heart defects
- Post-surgery for those who have a risk of blood clots
There are two types of blood thinners — anticoagulants and antiplatelet drugs. Some of the most common blood thinners include:
- Anticoagulants
- Apixaban (Eliquis)
- Dabigatran (Pradaxa)
- Edoxaban (Savaysa, Lixiana)
- Enoxaparin (Lovenox)
- Heparin
- Rivaroxaban (Xarelto)
- Warfarin (Jantoven)
- Anti-platelet drugs
- Aspirin
- Clopidogrel (Plavix)
- Dipyridamole (Persantine)
- Prasugrel (Effient)
- Ticagrelor (Brilinta)
