Side effects of Pradaxa include easy bruising or minor bleeding such as bleeding from cuts and nosebleeds, reports WebMD. Serious side effects of this medication include abdominal pain and acute heartburn, nausea or vomiting. Although serious allergic reactions to Pradaxa are uncommon, patients should seek immediate medical attention if they develop a rash, have difficulty breathing or feel severely dizzy.
Patients who are allergic to dabigatran (the generic form of this drug); those with an artificial heart valve; and patients who have an ongoing bleeding from an injury, surgery or another condition should not use Pradaxa, warns Drugs.com. Dabigatran may cause bleeding, especially in people who have a stomach ulcer or kidney disease or those who take medications that raise the risk of bleeding such as aspirin and heparin. Patients should not use this drug in smaller or larger doses, or for longer than the prescription period.
Pradaxa is used in the treatment of deep vein thrombosis and pulmonary embolism, as well as in reducing the possibility of their recurrence. This drug also decreases the risk of stroke and blood clots in patients with atrial fibrillation, notes Drugs.com. Pradaxa works by preventing platelets in the blood from fastening together and forming a blood clot.
