Contents of the pack and other information
1. What Dipyridamole Tablets are and what they are used for
Dipyridamole Tablets belong to a group of medicines called anti-coagulants, which are used to prevent the formation of
blood clots (deep vein thrombosis).
Dipyridamole Tablets are used to prevent blood clots
• when other anti-coagulants have not worked
• after grafting of arteries in heart operations such as heart by pass surgery
• occurring with the use of artificial heart valves.
2. What you need to know before you take Dipyridamole Tablets
Do not take Dipyridamole Tablets:
• 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 Dipyridamole Tablets:
• if you have angina (chest pains) or other heart problems (including circulation problems) or have had a recent heart
• if you have myasthenia gravis (a rare muscle problem)
• if you have any bleeding problems
• if you are pregnant or planning to become pregnant or are breast-feeding
• if you have been told by your doctor that you are intolerant to some sugars
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Dipyridamole Tablets.
Other medicines and Dipyridamole Tablets
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those
bought without a prescription. This is because Dipyridamole Tablets can affect the way some other medicines work. Also

• adenosine (for heart rhythm problems)
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 Tablets.
