Dipyridamole pour prévenir les caillots sanguins

About dipyridamole

In your blood there are 'sticky' cells called platelets. When you cut yourself, the platelets stick to each other (clot) to seal the wound. Sometimes platelets stick to each other inside a blood vessel - this is called a thrombus. A thrombus can block a blood vessel, and this is often the cause of a stroke or heart attack. This is more likely to happen if you have had surgery to replace a heart valve, or if you have blood vessel disease (for example, if you have had a stroke or a transient ischaemic attack).

Dipyridamole reduces the 'stickiness' of platelets. It will help to prevent a thrombus forming in an artery, which will reduce the risk of you having a heart attack or a stroke. It is often prescribed alongside other medicines to prevent blood clots. One such medicine is aspirin, which is another antiplatelet medicine.

Before taking dipyridamole

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking dipyridamole it is important that your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• If you have angina, or any other heart condition or circulation problem.

• Si vous souffrez d'hypotension.

• If you have any bleeding problems.

• If you have migraines, or if you have a muscle-weakening disease called myasthenia gravis. Dipyridamole can make these conditions worse.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

How to take dipyridamole

• Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about dipyridamole and a full list of side-effects which you may experience from taking it.

• Take dipyridamole exactly as your doctor tells you to. Your doctor or pharmacist will tell you how much to take and when to take it, and this information will also be printed on the label of the pack to remind you. As a guide, if you have been prescribed dipyridamole tablets, you will need to take three or four doses daily. If you have been prescribed dipyridamole capsules, you will need to take two doses daily, usually in the morning and the evening.

• There is an important difference in the way dipyridamole tablets and dipyridamole capsules are taken. If you have been supplied with tablets, take your doses 30-60 minutes before a meal. If you have been supplied with capsules, take your doses at the same time as a meal, or shortly afterwards.

• It can help to take your doses with a drink of water. Swallow the tablets/capsules whole - this means do not crush or chew the tablets, or open the capsules.

• Try to take your doses at the same times of day, each day. This will help you to remember to take them.

• If you do forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case leave out the forgotten dose. Do not take two doses together to make up for a missed dose.

Tirer le meilleur parti de votre traitement

• Essayez de vous rendre à vos rendez-vous réguliers avec votre médecin. Il pourra ainsi vérifier vos progrès.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take. For example, some indigestion remedies can interfere with the way your body absorbs dipyridamole, so they should not be taken at the same time of day. Also, it is recommended that you do not take any preparations containing aspirin without checking this first with your doctor. Several medicines for pain relief and cold relief that can be bought at retail outlets contain aspirin, so check the label carefully before you buy.

• If you are having an operation or any medical treatment, tell the person carrying out the treatment that you are taking dipyridamole.
