Dabigatran - What is it for

What are direct-acting oral anticoagulants (DOACs)?

  • Dabigatran is a direct-acting oral anticoagulants (DOACs) which are medicines used to prevent and treat blood clots.

  • This medicine interferes with normal blood clotting (coagulation). It is commonly known as a “blood thinner” although it does not actually cause the blood to become less thick, only less likely to clot. It helps to reduce the risk of blood clot formation or to treat blood clots that have already formed. Dabigatran does not dissolve clots that have already been formed but may prevent the clots from growing larger, while letting the body’s natural processes dissolve the clots.

  • People who are taking this medicine do not require frequent blood tests to check the effectiveness of the medicine. Your doctor may however order blood tests to check how well your kidneys and liver are working. If you have a severe kidney or liver problem, Dabigatran may not be the right medicine for you.
