About Dipyridamole

Dipyridamole is an antiplatelet medicine. It prevents a type of blood cell (platelets) sticking together and forming a dangerous blood clot.

Dipyridamole helps to prevent blood clots if you have an increased risk of having them. Your risk is higher if you've had:

• a stroke or "mini-stroke" (transient ischaemic attack or TIA)
• an operation on your heart to replace your heart valve

Dipyridamole is only available on prescription.

It comes as tablets and slow-release capsules (also called modified release). It's also available as a liquid if you find it difficult to swallow tablets or capsules.

Your doctor may prescribe dipyridamole alone or with daily low-dose aspirin.
