Anticoagulants inhibit the ability of blood to clot, or coagulate. They don't dissolve existing blood clots. They prevent new clots from forming or existing clots from getting larger.

Some of the major types of commonly prescribed cardiovascular medications are summarized in this section. For your information and reference, we have included generic names as well as major trade names to help you identify what you may be taking; however, the AHA is not recommending or endorsing any specific products.  If your prescription medication isn't on this list, remember that your healthcare provider and pharmacist are your best sources of information.  It's important to discuss all of the drugs you take with your doctor and understand their desired effects and possible side effects.  Never stop taking a medication and never change your dose or frequency without first consulting your doctor.

The most common use of anticoagulation is in people with a heart arrhythmia called atrial fibrillation. Most people with atrial fibrillation should take warfarin (Coumadin^®). Atrial fibrillation can cause a stroke. For those persons with atrial fibrillation, it is important that they take warfarin to prevent a stroke. Some people may not be able to take warfarin; in this case be sure to discuss all treatment options for preventing a stroke with your healthcare provider. 

Anticoagulants are also used to treat or prevent blood clots in the legs (known as deep venous thrombosis) or pulmonary embolus (blood clot in the lungs). 

Commonly prescribed anticoagulants include:  

Dalteparin (Fragmin^®)
Danaparoid (Orgaran^®)
Enoxaparin (Lovenox^®)
Heparin (Hep-Lock, Hep-Pak, Hep-Pak CVC, Heparin Lock Flush)
Tinzaparin (Innohep^®)
