L'aspirine pour prévenir les caillots sanguins

How does low-dose aspirin work?

Aspirin works by making platelets in the blood less sticky. Platelets help stop bleeding, but sometimes they can clump together inside a blood vessel and form a clot. This can block blood flow and cause a heart attack or stroke.

Low-dose aspirin (75 mg) helps stop platelets from sticking together, which reduces the risk of blood clots. It is often used for people with heart or blood vessel disease, or those who have had a heart attack, stroke, or heart surgery.

Low-dose aspirin is available with or without a prescription, but you should only take it regularly if your doctor recommends it, as it isn’t suitable for everyone.

À des doses plus élevées, l'aspirine est utilisée pour soulager la douleur et la température élevée (fièvre). Vous trouverez plus d'informations sur cette utilisation de l'aspirine dans la brochure intitulée L'aspirine contre la douleur ou la fièvre.

Side effects of low-dose aspirin

Common side effects of aspirin are:

• Sensation de malaise (nausée).

• Indigestion.

• Douleur à l'estomac.

• Bleeding more easily (such as nosebleeds or bruising).

Vous trouverez une liste complète dans la notice d'information du fabricant fournie avec votre médicament.

How to manage low-dose aspirin side effects

Les effets indésirables s'atténuent souvent au fur et à mesure que votre corps s'adapte au nouveau médicament, mais parlez-en à votre médecin ou à votre pharmacien si l'un des effets suivants persiste ou devient gênant.

Si vous ressentez d'autres symptômes qui pourraient être dus aux comprimés, demandez conseil à votre médecin ou à votre pharmacien.

Who should not take low-dose aspirin?

Some medicines aren’t suitable for everyone. Before taking aspirin to prevent blood clots, it’s important your doctor knows:

• Si vous êtes enceinte ou si vous allaitez.

• Si vous avez déjà eu un ulcère d'estomac.

• Si vous souffrez d'asthme.

• Si vous avez moins de 16 ans.

• Si vous avez des problèmes de fonctionnement du foie ou des reins.

• Si vous souffrez d'une maladie du sang telle que l'hémophilie ou d'un déficit en glucose-6-phosphate déshydrogénase (G6PD).

• Si vous avez la goutte.

• If you have high blood pressure (hypertension).

• If you have ever had an unusual or allergic-type reaction after taking aspirin or a non-steroidal anti-inflammatory drug (NSAID).

  • NSAIDs include ibuprofen, diclofenac, indometacin and naproxen. You should also let your doctor know if you have ever had an allergic reaction to any other medicine.

• 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.

Comment prendre de l'aspirine à faible dose

• Before taking aspirin, read the leaflet inside the pack for important information and possible side effects.

• You will usually be advised to take one 75 mg tablet once a day, unless your doctor tells you differently. Take it exactly as prescribed.

• Take aspirin at the same time each day to help you remember. Many people take it in the morning with breakfast.

• Check what type of aspirin you have:

  • Dispersible tablets should be mixed with water and taken with food to protect your stomach.

  • Gastro-resistant (enteric-coated) tablets can be taken without food. Swallow them whole with water and do not chew them.

• If you are taking gastro-resistant tablets, do not take indigestion remedies in the 2 hours before or after your dose.

• If you miss a dose, take it when you remember unless it’s the next day. Do not take two doses at once.

Tirer le meilleur parti de votre traitement

• Keep all your regular appointments with your doctor. This is so your doctor can check on your progress.

• Before taking any over-the-counter medicines, ask your pharmacist if they are safe with aspirin.

• Do not take other medicines that contain aspirin or anti-inflammatory painkillers such as ibuprofen, including many cold and flu remedies.

• Aspirin should not be given to children under 16 unless prescribed, because it may be linked to Reye’s syndrome, a very rare but serious illness.

• Si vous devez subir une opération ou un traitement dentaire, informez la personne chargée du traitement que vous prenez de l'aspirine. En effet, les saignements peuvent mettre plus de temps que la normale à s'arrêter.

• If a child accidentally takes aspirin, go to A&E immediately. Take the medicine packaging with you, even if it is empty.

How to store low-dose aspirin

• Conservez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.
