Pradaxa is a prescription blood thinner. People use Pradaxa to lower the chance of stroke and blood clots. The U.S. Food and Drug Administration warns that suddenly stopping Pradaxa or missing doses may increase the risk of blood clots or stroke. This can cause permanent disability and death. Pradaxa can also cause drug interactions if taken at the same time as certain medications. Side effects of Pradaxa include serious and sometimes fatal bleeding. The FDA gave full approval to a Pradaxa bleeding antidote in April 2018. Boehringer Ingelheim makes Pradaxa. The company recalled a batch of Pradaxa in 2012, citing a potential packaging defect.
Pradaxa (dabigatran) is an anticoagulant. People know it better as a blood thinner.
Boehringer Ingelheim makes Pradaxa. The U.S. Food and Drug Administration first approved Pradaxa in 2010.
Pradaxa can treat and prevent blood clots. This can reduce the risk of stroke.
Pradaxa is used in patients with atrial fibrillation (irregular heartbeat) not caused by a heart valve problem. It lowers the risk of stroke in these patients. It does this by cutting the risk that a blood clot will form in the heart and go to the brain.
The FDA also approved Pradaxa to treat deep vein thrombosis (DTV) and pulmonary embolism (PE) in patients who have been treated with injectable blood thinner for five to 10 days.
DTV is a serious condition that occurs when a blood clot forms in the deep veins in the body. This is usually in the legs and thighs. PE occurs when a blood clot becomes lodged in a blood vessel in the lung.
Doctors also prescribe Pradaxa to prevent DVT and PE in patients who have had hip replacement surgery.
Pradaxa is known as a direct thrombin inhibitor. It blocks the blood’s central clotting agent, thrombin. This lowers the chance of blood clots forming.
Pradaxa comes in 75 mg, 110 mg and 150 mg capsules. Most people take 150 mg capsules twice a day.
People with kidney problems may take lower doses of Pradaxa because the drug is eliminated through the kidneys. The FDA advises doctors to check a patient’s kidney function before prescribing Pradaxa and to reassess kidney function throughout treatment with the drug.
A patient’s doctor will explain the best way to take Pradaxa. But the drug’s manufacturer instructs patients to swallow Pradaxa whole with a full glass of water.
It advises patients not to break, chew or empty the capsules. Patients can take Pradaxa with or without food.
It is possible to overdose on Pradaxa. Overdosing on Pradaxa increases a patient’s risk of bleeding.
If a person suspects a Pradaxa overdose, he or she should immediately contact a poison control center or seek emergency treatment.
In November 2012, Boehringer Ingelheim announced a nationwide voluntary recall of a single manufacturing lot of Pradaxa 75 mg capsules. The company cited a potential packaging defect.
It warned that a damaged bottle could allow moisture to get into the bottle. This could harm the quality of the drug.
The most serious Pradaxa side effect is uncontrolled bleeding. For five years after the FDA approved Pradaxa, there was no way to reverse these bleeding events, and people sometimes died. There is now an antidote for Pradaxa bleeding.
Some people have filed Pradaxa lawsuits against Boehringer Ingelheim over bleeding injuries and deaths.
Researchers also have reported incidents of acute kidney failure, stroke and suspected liver failure with Pradaxa use. Other side effects of Pradaxa include gastrointestinal issues like indigestion, upset stomach, burning and stomach pain.
According to the drug’s prescribing information, you should not take Pradaxa if you have a mechanical prosthetic heart valve.
Pradaxa is also not appropriate for patients with active pathological bleeding or a history of hypersensitivity reaction to Pradaxa.
The FDA requires a black box warning — the agency’s strongest warning — to alert the public of the risk of spinal and epidural hematomas in patients treated with Pradaxa who are receiving neuraxial anesthesia or undergoing spinal puncture.
Pradaxa patients who have medicine injected into their spinal and epidural area, or have a spinal puncture, have a risk of forming a blood clot that can cause long-term or permanent paralysis.
Patients should not stop taking Pradaxa without first talking with their doctor. The FDA warns that missing doses may increase the risk of blood clots or stroke. Suddenly stopping Pradaxa also increases the risk of thrombotic events such as strokes.
