Patient leaflet - Dispersible Aspirin tablets BP 75 mg

1. WHAT DISPERSIBLE ASPIRIN TABLETS ARE AND WHAT THEY ARE USED FOR

Dispersible Aspirin Tablets contain the active substance aspirin. Aspirin belongs to a group of medicines called anti-platelet agents. Platelets are cells in the blood which cause the blood to clot. If a clot occurs in the artery it can cause a heart attack, angina (chest pain) or a stroke.

Dispersible Aspirin Tablets are used to help prevent blood clots in people who have had a stroke, heart attack, by-pass surgery or have angina.

This medicine is not for pain relief.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE DISPERSIBLE ASPIRIN TABLETS

If you are taking this medicine for the first time or if you are going to take this medicine in order to prevent blood clots, you should seek advice from your doctor before you commence therapy to make sure it is suitable for you.

This medicine can be taken by adults. However, some people should not take this medicine or should seek advice from their doctor or pharmacist before taking it.

Do Not take Dispersible Aspirin Tablets if you:

  • Are allergic to aspirin, other non-steroidal

    antiinflammatory drugs (NSAIDs), or any of the other ingredients of this medicine (listed in section 6) · Are under 16 years of age. 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 under 16 years unless on the advice of a doctor

    thrombocytopenia) or are taking medicines to thin your blood

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Dispersible Aspirin Tablets if you:

  • Are elderly as you may be more likely to suffer from side

    effects.

  • Suffer from an allergy or allergic disease such as asthma

    or hayfever, have nasal polyps or other chronic respiratory diseases

    • Are diabetic as aspirin may alter your insulin requirements · Have high blood pressure (hypertension), your doctor will

      want to monitor you while taking this medicine · Are dehydrated

    • Have a condition called glucose-6-phosphate

      dehydrogenase deficiency

    • Suffer from liver or kidney disease

If you are going to take this medicine long-term to help prevent a further heart attack or stroke, you should make sure this has been discussed with your doctor who will advise you about the risks as well as the benefits of taking aspirin.

If you experience any unusual symptoms or side effects such as abnormal bleeding, passing blood in your faeces (stools/motions), passing black tarry stools, or vomit any blood or dark particles that look like coffee granules, seek immediate medical help as these may be signs of a bleed in the stomach or intestines.

When taking acetylsalicylic acid, serious allergic reactions which may include chest pain and even heart attack (Kounis syndrome) have been reported (see section 4). Seek medical care immediately when you notice chest pain with allergic reactions (such as skin rashes, shortness of breath).

Tell your doctor or dentist if you are planning to have an operation as aspirin may cause an increased risk of bleeding.

This medicine is not suitable to use for the treatment of inflammation, pain or fever.

    sodium and naproxen

  • Medicines called corticosteroids which are used to treat

    many conditions such as eczema, rheumatoid arthritis and inflammatory conditions e.g. hydrocortisone, prednisolone
