What is dabigatran?
Dabigatran is used to lower the risk of stroke caused by a blood clot in people with a heart rhythm disorder called atrial fibrillation. dabigatran is used when the atrial fibrillation is not caused by a heart valve problem.
Dabigatran is also used to treat DVT or pulmonary embolism (PE), and to lower your risk of having a repeat DVT or PE.
Dabigatran may also be used for purposes not listed in this medication guide.
Dabigatran can cause you to bleed more easily. Call your doctor at once if you have: bleeding gums, nosebleeds, heavy menstrual periods or abnormal vaginal bleeding, blood in your urine, bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds.
Many other drugs can increase your risk of bleeding when used with dabigatran. Tell your doctor about all medicines you have recently used.
Dabigatran can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural). Tell any doctor who treats you that you are taking dabigatran.
Do not stop taking dabigatran without first talking to your doctor. Stopping suddenly can increase your risk of blood clot or stroke.
Before taking this medicine
You should not take dabigatran if you are allergic to it, or if you have:
an artificial heart valve; or
active bleeding from a surgery, injury, or other cause.
Dabigatran can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural). This type of blood clot could cause long-term paralysis, and may be more likely to occur if:
you have a genetic spinal defect;
you have a spinal catheter in place;
you have a history of spinal surgery or repeated spinal taps;
you have recently had a spinal tap or epidural anesthesia;
you are using other medicines to treat or prevent blood clots.
Dabigatran may cause you to bleed more easily, especially if:
you have a stomach ulcer or bleeding in your stomach or intestines;
you are older than 75.
Tell your doctor if you have ever had:
a bleeding disorder that is inherited or caused by disease;
antiphospholipid syndrome (also called Hughes syndrome or "sticky blood syndrome"), an immune system disorder that increases the risk of blood clots;
a stomach ulcer; or
if you have been taking rifampin.
Tell your doctor if you are pregnant or if you become pregnant. Taking dabigatran during pregnancy may cause bleeding in the mother or the newborn baby. However, the risk of blood clots is higher during pregnancy. The benefit of preventing a blood clot may outweigh any risks to the baby.
You should not breast-feed while using dabigatran.
How should I take dabigatran?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take dabigatran with a full glass of water. You may take dabigatran with or without food.
Swallow the capsule whole and do not crush, chew, break, or open it.
Because dabigatran keeps your blood from coagulating (clotting) to prevent unwanted blood clots, this medicine can also make it easier for you to bleed, even from a minor injury such as a fall or a bump on the head. Contact your doctor or seek emergency medical attention if you fall or hit your head, or have any bleeding that will not stop.
If you need surgery, dental work, or any type of medical test or treatment, tell the doctor or dentist ahead of time if you have taken dabigatran within the past 12 hours.
Your kidney function may need to be checked before and during treatment with dabigatran.
