Dabigatran etexilate mesylate, also known by its brand name, Pradaxa, is a type of anticoagulant blood thinner that treats and prevents certain types of blood clots in people ages 8 years and older. It's also used to lower the risk of stroke and blood clots in people with atrial fibrillation (AFib). The dosing can differ based on why you need the medication, but it's typically taken by mouth twice a day. Side effects include stomach upset and bleeding. For people who experience serious bleeding with this medication, there's an antidote medication called Praxbind (idarucizumab) that reverses its effects.
Adults:
Lowering the risk of stroke or blood clots in people with atrial fibrillation (AFib) that isn't caused by a heart valve problem
Treating blood clots in the legs (deep vein thrombosis (DVT)) or lungs (pulmonary embolism (PE)) - only after receiving an injectable blood thinner for 5-10 days
Lowering the risk of blood clots from happening again in the legs (DVT) or lungs (PE) in people with a history of blood clots
Preventing blood clots in the legs (DVT) or lungs (PE) after hip replacement surgery
Children 8 years and older:
Treating blood clots - only after receiving an injectable blood thinner
Lowering the risk of blood clots from happening again in children with a history of blood clots
Dabigatran (Pradaxa) is an anticoagulant known as a direct thrombin inhibitor. It works by blocking thrombin, a protein that's needed for blood clots to form. By stopping thrombin from working, it prevents blood clots from forming. This lowers the risk of stroke, and treats and prevents clots in your arms or legs.

If you get more than one bottle of dabigatran (Pradaxa) from the pharmacy, only open one bottle at a time. Keep the bottle tightly closed when you aren't using it to protect the medication from moisture. Once a bottle is opened, the medication is only good for 4 months. Throw away any unused capsules after 4 months.
You can take dabigatran (Pradaxa) with or without food. If it's hurting your stomach, taking it with food can help.
Take your dabigatran (Pradaxa) doses at about the same time every day. This helps to make sure the levels of the medication in your body are consistent.
If you accidentally miss a dose of dabigatran (Pradaxa), take it as soon as you can that same day. But if it’s less than 6 hours before your next dose, skip the missed dose. Don’t double up to make up for it.
Swallow dabigatran (Pradaxa) capsules whole with a full glass of water. Don't open, chew, break, or crush them. This can cause your body to absorb too much medication and raise your risk of bleeding.
Dabigatran (Pradaxa) can make you bleed and bruise more easily. Get medical help right away if you feel lightheaded, dizzy, are vomiting or coughing up blood, or have blood in your stool. These are signs of bleeding that might be happening inside your body.
If you're going to have a dental procedure or surgery, make sure your healthcare care team knows you're taking dabigatran (Pradaxa). Depending on the surgery, you might need to temporarily stop taking this medication for a couple days before to lower your risk for severe bleeding.
Get medical help if you fall and hit your head while taking dabigatran (Pradaxa). You should be urgently seen to make sure you don't have any brain bleeds.
Dabigatran (Pradaxa) can interact with many commonly-used supplements, over-the-counter (OTC) products, and prescription medications. Make sure to tell your care team about all of the medications you're taking or planning on taking with dabigatran (Pradaxa). They can make sure your medications are as safe for you as possible.
Dabigatran (Pradaxa) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Stopping dabigatran (Pradaxa) too early
Don't stop taking dabigatran (Pradaxa) unless a healthcare professional specifically tells you it's safe to do so. Stopping the medication too early can cause blood clots to form in your body.
Let your prescriber know if you experience symptoms of blood clots, such as:
Risk factors: Spinal puncture (spinal tap) | Getting anesthesia in the spine (epidural anesthesia) | History of spinal surgery | Taking other medications that raise the risk for bleeds
If you're having certain types of spinal procedures, taking dabigatran (Pradaxa) can raise your risk for getting a hematoma (pooling of blood) around the spinal cord. Sometimes, hematomas can lead to serious complications, such as paralysis. If you're getting a spinal procedure, a member of your care team might ask you to temporarily stop taking dabigatran (Pradaxa) to lower your risk of spinal hematomas. Let your care team know right away if you notice symptoms such as numbness or weakness of your legs, or bowel or bladder problems - these can be signs of problems with your spine.
Risk factors: Older than age 75 | Kidney problems | Stomach bleeding or ulcer | Taking other medications that raise the risk for bleeding (e.g., antiplatelets, anticoagulants, NSAIDs, corticosteroids)
Taking dabigatran (Pradaxa) can raise your risk for bleeding. Your risk is higher if you're also taking other medications that can cause bleeding. If you end up with a life-threatening bleed, your prescriber will consider giving you a medication called Praxbind (idarucizumab) to reverse the effects of dabigatran (Pradaxa). Let your prescriber know if you have a fall, head injury, or other kinds of physical injury - they might need to check you for bleeding inside your body. Get medical help right away if you have dark or tarry stool or bleeds that are difficult to stop.
There are certain medications that can change the amount of dabigatran (Pradaxa) in your body. Some interactions can cause more bleeding and side effects, while others can stop dabigatran (Pradaxa)) from working as well. Let your prescriber and pharmacist know about other prescriptions, over-the-counter medications, vitamins, and herbal supplements you're taking or have stopped recently.
People who have artificial heart valves should avoid taking dabigatran (Pradaxa) since it can raise their risk of experiencing stroke, heart attack, blood clots, and life-threatening bleeding. If you need to take a blood thinner but have an artificial heart valve, talk to your prescriber about other options.
Dabigatran (Pradaxa) shouldn't be used in people with antiphospholipid syndrome because it hasn't been shown to work well.
