Your medicine is called Aspirin 300mg Tablets (called Aspirin Tablets throughout the rest of this leaflet).

What this medicine does

Aspirin Tablets are used for the symptomatic relief of mild to moderate pain, including migraine, toothache, neuralgia, headache, sore throat, period pains, aches and pains (including muscle pains and backache). For the symptomatic relief of influenza, feverishness and feverish colds. For the symptomatic relief of sprains, strains, rheumatic pain, sciatica, lumbago, fibrositis, joint swelling and stiffness.

Aspirin belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). Aspirin works by preventing the release in the body of substances which cause pain, inflammation and fever.


There is a possible association between aspirin and Reye's Syndrome when given to children. Reye's syndrome is a very rare disease, which can be fatal. For this reason aspirin should not be given to children aged under 16 years, unless on the advice of a doctor.

Do not take Aspirin Tablets if you:

•    are allergic (hypersensitive) to aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs) e.g. ibuprofen, or any of the other ingredients of Aspirin Tablets (see Section 6 What Aspirin Tablets contain). Symptoms may include rhinitis (runny nose), swollen face, mouth or tongue, itchy rash or asthma attack;

•    have or have had a stomach ulcer;

•    have a condition where your blood does not clot properly (e.g. haemophilia);

•    are taking medicines to thin your blood such as warfarin;

•    have or have had gout;

•    are in the last 3 months of pregnancy or are breast-feeding.

Talk to your doctor or pharmacist if any of the following apply to you:

•    if you have asthma, or suffer from allergies;

If you suddenly stop taking corticosteroids you may develop aspirin poisoning.

•    Metoclopramide (used to treat nausea and vomiting): it may increase the effect of aspirin.

•    Adsorbents e.g. kaolin (for diarrhoea) and Antacids e.g. aluminium hydroxide and magnesium carbonate (used to treat indigestion): these medicines may reduce the effect of aspirin.

you take one of these medicines below with aspirin you may increase the likelihood of bleeding.

•    ACE Inhibitors or Angiotensin-II Receptor Antagonists

e.g. captopril, enalapril maleate, valsartan, losartan (used to lower high blood pressure): taken with aspirin these medicines may not be as effective and you may suffer from kidney problems.

•    Antidepressants (used to treat depression) e.g.

Selective Serotonin Re-uptake Inhibitors (SSRIs) (such as venlafaxine): if taken with aspirin you may increase the likelihood of bleeding.

•    Medicines to control epilepsy e.g. phenytoin and valproate: aspirin may increase the effect of these medicines. If you take sodium valproate with aspirin you may increase the likelihood of bleeding.

•    Zafirlukast (used to prevent or treat asthma).

•    Spironolactone (diuretic) water tablets, Probenicid or Sulfinpyrazone (used to treat gout): if taken with aspirin these medicines may not be as effective.

•    Methotrexate (used in the treatment of arthritis, Crohn's disease and cancer) or Carbonic anhydrase inhibitors e.g. acetazolamide (used in the treatment of glaucoma, epilepsy and excess water retention): if taken with aspirin the side effects of these medicines may become more severe.
