1. What Aspirin tablets is and what it is used for
  • Aspirin belongs to a group of medicines called antiplatelet agents that help prevent your blood cells sticking together and forming a blood clot.
  • Aspirin tablets are principally used to prevent blood clots forming following a heart attack or stroke or to help prevent heart attacks and strokes in patients who have previously suffered from these conditions. They may have been prescribed for you if you have recently had by-pass surgery.

2. What you need to know before you take Aspirin tablets
Do not take Aspirin tablets:
  • if you are allergic to aspirin or any of the other ingredients of this medicine (listed in section 6)
  • are allergic to other salicylates or nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs are often used for arthritis or rheumatism and pain
  • have had an asthma attack or swelling of some parts of the body e.g. face, lips, throat or tongue (angioedema) after taking salicylates or NSAIDs
  • if you have, or ever had, an ulcer in your stomach or intestine
  • if you have, or ever had, a bleed in your stomach or intestines (you may have been sick and it contained blood or dark particles that looked like coffee grounds and/or passed blood in your stools or passed black tarry stools)
  • if you have had other types of bleeding like a stroke
  • if you have a blood clotting disorder (e.g. haemophilia or thrombocytopenia) or are taking medicines to thin your blood
  • if you have gout
  • if you have severe kidney or liver problems
  • if you are in your last 3 months of pregnancy; you must not use higher doses than 100mg per day (see section “Pregnancy and breast-feeding”)
  • if you are taking a medicine called methotrexate (e.g. for cancer or rheumatoid arthritis) in doses higher than 15mg per week

Warnings and precautions

Talk to your doctor or pharmacist before taking Aspirin tablets:

  • if you are asthmatic, have hay fever, nasal polyps or other chronic respiratory diseases; aspirin may induce asthma attack
  • if you have other kidney, liver or heart problems
  • if you have high blood pressure (your doctor may want to monitor you closely)
  • if you are dehydrated
  • if you have a condition called glucose-6-phosphate dehydrogenase deficiency
  • if you are elderly (your doctor may want to monitor you closely)
  • if you have or have ever had problems with your stomach or small intestine
  • if you have heavy menstrual periods
  • if you have ever had gout

You must immediately seek medical advice, if your symptoms get worse or if you experience severe or unexpected side effects e.g. unusual bleeding symptoms, serious skin reactions or any other sign of serious allergy (see section “Possible side effects”).

Inform your doctor if you are planning to have an operation (even a minor one, such as tooth extraction) since Aspirin is blood-thinning there may be an increased risk of bleeding.

Aspirin may cause Reye’s syndrome when given to children. Reye’s syndrome is a very rare disease which affects the brain and liver and can be life threatening. For this reason, Aspirin tablets should not be given to children aged under 16 years, unless on the advice of a doctor.

You should take care not to become dehydrated (you may feel thirsty with a dry mouth) since the use of Aspirin at the same time may result in deterioration of kidney function.

This medicinal product is not suitable as a pain killer or fever reducer.

If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist.

Other medicines and Aspirin tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, particularly the following:

The effects of treatment may be influenced if aspirin is taken at the same time as other medicines for:

  • Thinning of the blood/prevention of clots (e.g. warfarin, heparin, phenindione and clopidogrel)
  • Medicines for depression (selective serotonin re-uptake inhibitors (SSRIs) such as sertraline or paroxetine)
  • Methotrexate (for cancer, skin problems, rheumatic problems, Crohn’s disease)
  • Ciclosporin or tacrolimus (given after transplant surgery, or psoriasis or rheumatism)
  • Other non-steroidal anti-inflammatory medicines, like ibuprofen (to relieve pain, reduce swollen joints, muscles and ligaments)
  • Use as hormone replacement therapy when the adrenal glands or pituitary gland have been destroyed or removed, or to treat inflammation, including rheumatic diseases and inflammation of the intestines (corticosteroids)
  • Phenytoin and sodium valproate (for epilepsy)
  • Medicines for diabetes, such as glibenclamide, glipizide (sulphonylureas) or insulin
  • Medicines used to treat high blood pressure like ACE inhibitors (e.g. ramipril, captopril)
  • Water tablets (diuretics e.g. spironolactone and acetazolamide)
  • Probenecid and sulfinpyrazone (for gout)
  • Lithium (for severe mental problems)
  • Medicines for heart problems (e.g. digoxin)
  • Acetazolamide (for glaucoma)
  • Metamizole (substance to decrease pain and fever) may reduce the effect of acetylsalicylic acid on platelet aggregation (blood cells sticking together and forming a blood clot), when taken concomitantly. Therefore, this combination should be used with caution in patients taking low dose aspirin for cardioprotection

Before taking aspirin you should inform a healthcare professional about the medicines you are taking. If you are using aspirin regularly you should seek advice before taking any other medicine (including medicine you may have bought).

Aspirin tablets with alcohol

Do NOT drink alcohol whilst taking this medicine. Drinking alcohol may possibly increase the risk of gastrointestinal bleeding and prolong bleeding time.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

If you continue or start treatment with acetylsalicylic acid during pregnancy per instruction of the physician, then use acetylsalicylic acid as advised by your doctor and do not use a higher dose than is recommended.

Pregnancy – last trimester

Do not take acetylsalicylic acid higher than 100 mg per day if you are in the last 3 months of pregnancy as it could harm your unborn child or cause problems at delivery.

It can cause kidney and heart problems in your unborn baby. It may affect your and your baby’s tendency to bleed and cause labour to be later or longer than expected.

If you take acetylsalicylic acid at low doses (up to and including 100 mg per day), you need strict obstetric monitoring as advised by your doctor.

Pregnancy – first and second trimester

You should not take acetylsalicylic acid during the first 6 months of pregnancy unless absolutely necessary and advised by your doctor. If you need treatment during this period or while you are trying to get pregnant, the lowest dose for the shortest time possible should be used. If taken for more than a few days from 20 weeks of pregnancy onward, acetylsalicylic acid can cause kidney problems in your unborn baby that may lead to low levels of amniotic fluid that surrounds the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the heart of the baby. If you need treatment for longer than a few days, your doctor may recommend additional monitoring.

Breast-feeding

Breast-feeding women should not take Aspirin tablets unless advised by their doctor.

Driving and using machines

These tablets do not usually affect the ability to drive or operate machinery.

Aspirin tablets contains lactose

Lactose is a type of sugar. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

In some circumstances a higher dose may be appropriate, especially in the short term, and up to 4 tablets daily may be used on the advice of a doctor.

Caution is required in elderly patients who are more prone to adverse events. Treatment should be reviewed at regular intervals.

Do not give to children aged under 16 years unless on the advice of doctor. 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.
