Who should not take aspirin?

Some medicines aren’t suitable for everyone. Before taking aspirin, your doctor or pharmacist needs to know:

• Om du är gravid, försöker bli gravid eller ammar.

• If you have ever had a stomach ulcer or gout.

• Om du har astma eller någon annan allergisk sjukdom.

• If you have any problems with the way your liver works or with the way your kidneys work.

• If you have heart failure or a problem with your thyroid gland.

• If you have a blood disorder such as haemophilia, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.

• 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 och naproxen. You should also let your doctor know if you have ever had an allergic reaction to any other medicine.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

How to take aspirin

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

• Take aspirin exactly as directed on the label or by your healthcare professional.

  • The usual dose is 1-3 tablets (300 mg each) every 4-6 hours as needed.

  • Do not take more than 13 tablets (4 g) in 24 hours.

• If you have been given soluble (dispersible) tablets, take each of your doses stirred into a small glass of water.

• Take regular aspirin with or just after food to help reduce stomach irritation.

• Gastro-resistant (enteric-coated) aspirin can be taken before food, as the coating helps protect your stomach.

  • Swallow these tablets whole with water - do not crush or chew them.

• Do not take indigestion remedies in the 2 hours before or after taking gastro-resistant aspirin, as they can stop the coating from working properly.

• Melt-in-the-mouth (orodispersible) tablets should be placed on the tongue and allowed to dissolve. Take care not to handle the tablets too much before placing on the tongue.

• If you forget to take a dose, do not worry. Ta inte två doser samtidigt to make up for a forgotten dose.

Få ut det mesta av din behandling

• Aspirin must not be given to children under 16 unless prescribed by a doctor, as it is linked to a rare but serious condition called Reye’s syndrome.

• Before taking any over-the-counter medicines, check with a pharmacist.

• Do not take aspirin with other medicines that contain aspirin or with anti-inflammatory painkillers like ibuprofen. Many painkillers and cold and flu remedies contain these, so always read the label.

• If you think too much aspirin has been taken, or a child may have taken it by accident, go to A&E immediately. Take the medicine packaging with you, even if it’s empty.

How to store aspirin

• Förvara alla läkemedel utom räckhåll och synhåll för barn.
