Patient leaflet - Dipyridamole 200 mg prolonged-release capsules

1. What Dipyridamole capsules are and what they are used for

The name of your medicine is Dipyridamole capsules. It contains a medicine called Dipyridamole. This belongs to a group of medicines called ‘anti-thrombotic agents’, which are used to help stop blood clots forming.

Dipyridamole capsules are used:

  • To help stop blood clots which may occur if you have had your heart valves replaced.
  • In people who have had a stroke caused by a blood clot in the brain. This medicine reduces the risk of having another stroke.

2. What you need to know before you take Dipyridamole capsules

Do not take Dipyridamole capsules:

  • If you are allergic to dipyridamole or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before taking Dipyridamol capsules if:

  • have angina or other heart problems (including heart valve or circulation problems) or have had a recent heart attack
  • You have myasthenia gravis (a rare muscle problem)
  • You have any bleeding problems
  • You are pregnant or planning to become pregnant or are breast-feeding

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking this medicine.

Children and adolescents

Dipyridamole should not be given to children.

Other medicines and Dipyridamole capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription or herbal medicines.

  • Aspirin (or planning to take aspirin for any condition)
  • Adenosine injection - used for heart problems or tests on the heart
  • Warfarin or other medicines to stop blood clots forming. If so, tell them at your next visit to the anticoagulant clinic that you are now taking dipyridamole.

If you are having heart tests

This medicine contains dipyridamole. Dipyridamole is also sometimes given as an injection during tests to see if the heart is working properly (also called ‘myocardial imaging’). This means that the test and your medicine may contain the same substance. If you are going to have an injection of dipyridamole, tell the doctor that you are taking Dipyridamole capsules.
