Dabigatran (dabigatran etexilate) — Uses, Dosage, Side Effects & Safety

Drug class: Direct Oral Anticoagulant (DOAC)

Overview

Dabigatran is a prescription medication used to prevent and treat blood clots. It is commonly prescribed for people with atrial fibrillation (an irregular heartbeat) to lower the risk of stroke, as well as for the prevention and treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE). Dabigatran works by blocking thrombin, an enzyme involved in blood clot formation, making it easier for blood to flow and reducing the risk of dangerous clots. Unlike older anticoagulants, dabigatran does not require frequent blood tests or dietary restrictions. However, it is important to take it exactly as prescribed and not to stop suddenly without medical advice, as this can increase the risk of stroke or blood clots. Patients should be aware of signs of bleeding and inform their healthcare provider about all medications and supplements they are taking.
