Generic Name: dabigatran (da BIG a tran)
Brand Names: Pradaxa
What is Pradaxa?
Pradaxa (dabigatran) helps to prevent platelets in your blood from sticking together and forming a blood clot.
Pradaxa is used to reduce the risk of stroke and blood clots in people who have a medical condition called atrial fibrillation.
Pradaxa is also used to treat blood clots in the veins of your legs (deep vein thrombosis) or lungs (pulmonary embolism) and reduce the risk of them occurring again.
You should not take Pradaxa if you have an artificial heart valve, or if you have any active bleeding from a surgery, injury, or other cause.
Because Pradaxa 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. Avoid activities that may increase your risk of bleeding or injury. Contact your doctor or seek emergency medical attention if you have bleeding that will not stop.
Pradaxa can cause a very serious blood clot around your spinal cord if you undergo a spinal tap or receive spinal anesthesia (epidural), especially if you have a genetic spinal defect, if you have a spinal catheter in place, if you have a history of spinal surgery or repeated spinal taps, or if you are also using other drugs that can affect blood clotting. This type of blood clot can lead to long-term or permanent paralysis.
Get emergency medical help if you have symptoms of a spinal cord blood clot such as back pain, numbness or muscle weakness in your lower body, or loss of bladder or bowel control.
Do not stop taking Pradaxa without your doctor's advice. Stopping the medication can increase your risk of stroke.
