1. What Dipyridamole Oral Suspension is and what it is used for

The name of your medicine is Dipyridamole Oral Suspension (called dipyridamole in this leaflet). It contains dipyridamole. This belongs to a group of medicines called anti-platelet agents.

Dipyridamole helps to stop blood clots forming, particularly when you have artificial heart valves.

2. What do you need to know before you take Dipyridamole Oral Suspension
Do not take Dipyridamole and tell your doctor if:
  • You are allergic to dipyridamole or any of the other ingredients of this medicine (listed in section 6). The signs of an allergic reaction include a rash, itching or shortness of breath.

If this applies to you, do not take this medicine and talk to your doctor.

Warnings and precautions

Before you take Dipyridamole, tell your doctor if:

  • You have angina, have recently had a heart attack or you have heart or circulation problems
  • You have a bleeding problem
  • You have myasthenia gravis. This is a disorder that causes severe tiredness and muscle weakness particularly in the face and throat.

If you are not sure if any of the above apply 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 any other medicines.

This includes medicines you buy without a prescription, including herbal medicines. This is because dipyridamole can affect the way some other medicines work. Also, some medicines can affect the way dipyridamole works.

In particular, tell your doctor if you are taking any of the following:

  • Aspirin, a medicine to thin your blood
  • Medicines that stop clots from forming, such as warfarin
  • Medicines that lower blood pressure
  • Medicines that help muscle control, such as neostigmine
  • Antacids, used to treat indigestion.

If you are to have an injection of adenosine that is used to treat unusual heart rhythms, tell the doctor that you are taking Dipyridamole Oral Suspension.

Having a heart test using an injection of dipyridamole

Dipyridamole is sometimes given as an injection to see if the heart is working properly (myocardial imaging). If you are going to have an injection of dipyridamole, tell the doctor that you are taking Dipyridamole Oral Suspension.

Pregnancy and breast-feeding

You should not be given Dipyridamole if you are pregnant, likely to get pregnant, or are breast-feeding.
