Dipyridamole

Dipyridamole is used with other drugs to reduce the risk of blood clots after heart valve replacement. It works by preventing excessive blood clotting.

Dipyridamole comes as a tablet to take by mouth. It is usually taken 4 times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dipyridamole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Continue to take dipyridamole even if you feel well. Do not stop taking dipyridamole without talking to your doctor.
