Who can and cannot take dipyridamole

Most adults aged 18 years or over can take dipyridamole to prevent strokes or to prevent blood clots after heart valve replacement surgery.

It's sometimes prescribed for children to treat a rare condition called Kawasaki disease or to prevent blood clots after heart surgery.

Dipyridamole is not suitable for some people. To make sure it's safe for you, tell your doctor if you:

• have ever had an allergic reaction to dipyridamole or any other medicine
• have angina or other heart problems, or have recently had a heart attack
• have myasthenia gravis, a rare condition that causes muscle weakness
• have any bleeding disorders, such as haemophilia or von Willebrand disease
• have low blood pressure (hypotension)
• have migraines
• are trying to get pregnant, already pregnant or breastfeeding
