Uses
Dabigatran is used to treat deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in people who have been treated with an injectable anticoagulant (‘blood thinner’). It is also used to reduce the risk of a DVT and PE from happening again after initial treatment is completed. Dabigatran is used to help prevent DVT and PE in people who have had hip replacement surgery. Dabigatran is also used to help prevent strokes or serious blood clots in people who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body, and possibly causing strokes) without heart valve disease. Dabigatran is in a class of anticoagulant medications called direct thrombin inhibitors. It works by preventing blood clots from forming in the body.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

Dosage Of Dabigatran
Dabigatran comes as a capsule to take by mouth. When dabigatran is used to treat or prevent DVT or PE or to prevent strokes or serious blood clots in people who have atrial fibrillation, it is usually taken twice a day. When dabigatran is used to prevent a DVT or PE after hip replacement surgery it is usually taken 1 to 4 hours after surgery, and then once a day for another 28 to 35 days. Dabigatran may be taken with or without food. Take dabigatran at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dabigatran exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the capsules whole with a whole glass of water; do not split, chew, or crush them. Do not open the capsules and sprinkle the contents on food or into drinks.
Dabigatran will help prevent strokes and blood clots only as long as you continue to take it. Continue to take dabigatran even if you feel well. Make sure to refill your prescription before you run out of medication so that you will not miss doses of dabigatran. Do not stop taking dabigatran without talking to your doctor. If you suddenly stop taking dabigatran, the risk that you will have a clot or a stroke may increase.
Other
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
