Aspirin zur Vorbeugung von Blutgerinnseln

About aspirin to prevent blood clots

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.

At higher doses, aspirin is used to relieve pain and high temperature (fever). There is more information about this use of aspirin in a leaflet called Aspirin gegen Schmerzen oder Fieber.

Häufige Nebenwirkungen von Aspirin sind:

• Übelkeit.

• Verdauungsstörungen.

• Magenschmerzen.

• Leichteres Bluten (wie Nasenbluten oder Blutergüsse).

You will find a full list in the manufacturer's information leaflet supplied with your medicine.

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

• Wenn Sie schwanger sind oder stillen.

• If you have ever had a stomach ulcer.

• Wenn Sie Asthma haben.

• If you are under 16 years of age.

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber oder Ihrer Nieren haben.

• Wenn Sie eine Blutkrankheit wie Hämophilie oder einen Glucose-6-Phosphat-Dehydrogenase (G6PD)-Mangel haben.

• If you have gout.

• Wenn Sie hoher Blutdruck (Hypertonie).

• 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 und Naproxen. Sie sollten Ihren Arzt auch informieren, wenn Sie jemals eine allergische Reaktion auf ein anderes Medikament hatten.

• Wenn Sie andere Medikamente einnehmen. Dazu gehören alle Medikamente, die Sie einnehmen und die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Medikamente.

• Bevor Sie Aspirin einnehmen, lesen Sie die Packungsbeilage für wichtige Informationen und mögliche Nebenwirkungen.

• 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. Nehmen Sie nicht zwei Dosen auf einmal.

• 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.

• If you are due to have an operation or dental treatment, tell the person carrying out the treatment that you are taking aspirin. This is because any bleeding may take longer than normal to stop.

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

• Bewahren Sie alle Medikamente außerhalb der Reichweite und Sicht von Kindern auf.

• An einem kühlen, trockenen Ort aufbewahren, fern von direkter Hitze und Licht.

How long does it take for aspirin to prevent blood clots?

Aspirin starts to reduce platelet stickiness within about 1 hour of taking a dose. However, its full protective effect against blood clots is usually reached after several days of taking it daily.

Is it safe to take aspirin as a blood thinner long-term?

Yes, low-dose aspirin can be taken long-term as a blood thinner, but only under a doctor’s supervision. Long-term use can increase the risk of stomach irritation, ulcers, or bleeding, so your doctor will weigh the benefits against the risks and may recommend stomach protection if needed.

Can anyone take aspirin to prevent blood clots?

No, not everyone should take aspirin to prevent blood clots. It is only recommended for people with heart or blood vessel problems, a history of heart attack or stroke, or high clot risk, and should never be taken by children under 16 or anyone without a doctor’s advice
