Why is this medication prescribed?

Dipyridamole is commonly prescribed for several medical conditions, but its primary use is to prevent blood clots. It’s often prescribed alongside other medications to reduce the risk of stroke in people who have had transient ischemic attacks (TIAs) or have had previous strokes. Additionally, it’s used in combination with other drugs to prevent blood clots after heart valve replacement surgery. Dipyridamole works by preventing platelets in the blood from sticking together, thus reducing the likelihood of clot formation.

It’s important not to crush or chew extended-release tablets; they should be swallowed whole.

It’s crucial to take dipyridamole exactly as prescribed and not to stop taking it without consulting your healthcare provider, as doing so could increase the risk of blood clots and other complications. If you have any questions or concerns about how to use dipyridamole, it’s best to discuss them with your healthcare provider.
