Dipyridamole — Uses, Dosage, Side Effects & Safety

Drug class: Antiplatelet agent; Vasodilator

Overview

Dipyridamole is a medication used to help prevent blood clots, most commonly after heart valve replacement or to reduce the risk of stroke in certain patients. It is often prescribed alone or in combination with other antiplatelet drugs, such as aspirin. Dipyridamole works by preventing platelets in your blood from sticking together and forming clots. It also widens (dilates) blood vessels, which can improve blood flow. This dual action helps lower the risk of serious complications like stroke or heart attack. Key points: Take dipyridamole exactly as prescribed, and do not stop suddenly without your doctor's advice. Let your healthcare provider know about all other medicines you take, as dipyridamole can interact with several drugs. Common side effects include headache and dizziness.
