1. What Dipyridamole is and what it is used for

Dipyridamole belongs to a group of medicines called ‘anti-thrombotic agents’, which are used to help stop blood clots forming.

Dipyridamole helps stop blood clots which may occur if you have had your heart valves replaced.

2. What you need to know before you take Dipyridamole

Do not take Dipyridamole if:

  • You are allergic (hypersensitive) to dipyridamole or any of the other ingredients of this medicine (listed in section 6: Contents of the pack and other information).

Warnings and precautions

Talk to your doctor or pharmacist before taking Dipyridamole if:

  • you 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
  • you have been told by your doctor that you have an intolerance to some sugars.

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

Other medicines and Dipyridamole

Tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicine. This includes medicines obtained without a prescription and herbal medicines. Dipyridamole may affect or be affected by other medicines.

In particular tell your doctor or pharmacist if you are taking any of the following medicines:

  • Medicines for high blood pressure

  • Antacids - for indigestion
  • 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

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.

Pregnancy and Breast-feeding

  • If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
