GENERIC NAME: Dabigatran



What is Dabigatran for?

Dabigatran belongs to a class of medications called direct thrombin inhibitors. It works by blocking the clotting factors and hence slows down the process of blood clot formation. It can be used to prevent or treat blood clots from different causes. You may be prescribed Dabigatran after hip or knee replacement or for the prevention of stroke in people with atrial fibrillation (a type of irregular heart rhythm). It can also be used to treat venous thrombosis (blood clot formed within a vein).

How to use it?

Dabigatran is taken by mouth as tablets. The usual adult dose used for atrial fibrillation is 75-150 mg twice daily. If you are taking Dabigatran for preventing a blood clot after hip or knee replacement, the usual doses are 75-220 mg once daily. When treating a blood clot, the usual dose is 150 mg twice daily. The lower doses of Dabigatran are frequently used in the elderly and in people with reduced kidney function.

What are the side effects of Dabigatran? 

Like other antiplatelet (Aspirin) or anticoagulant drugs (Warfarin), the most common side effect of Dabigatran is bleeding. You must tell your doctor if you notice any signs of bleeding like unexplained bruises and nose or gum bleeds, as well as signs of internal bleeding like blood in your urine or stool. Other common side effects are stomach upset and pain.
