When given to children aspirin may cause Reye’s syndrome. 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.

If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take Nu-Seals 300.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. The effect of treatment may be influenced if aspirin is taken at the same time as some other medicines for:

• thinning of the blood/prevention of clots (e.g. warfarin)
• organ rejection after transplantation (e.g. ciclosporin, tacrolimus)
• high blood pressure (e.g. diuretics and ACE-inhibitors)
• pain and inflammation (e.g. anti-inflammatory medicines such as ibuprofen, or steroids)
• gout (e.g. probenecid)
• cancer or rheumatoid arthritis (e.g. methotrexate).
• 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.

• insulin or any other drug to treat diabetes
• corticosteroids (used 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)
• phenytoin or sodium valproate (used to control epilepsy)
• sulphonamides (a type of antibiotic) such as sulfamethoxazole
• medicines such as acetazolamide used to treat glaucoma
• an anaesthetic called thiopental
• gold, which is sometimes used in rheumatic conditions
• antiplatelet drugs (such as clopidogrel and dipyridamole)
• selective serotonin re-uptake inhibitors (SSRIs) for depression such as sertraline or paroxetine
• antacids (indigestion medicine). Do not take antacids just before or after taking Nu-Seals 300 as they may cause the aspirin to be released too soon.

If you consume excessive amounts of alcohol whilst taking Nu-Seals 300, you may increase the risk of causing bleeding in your stomach or intestines.

Tell your doctor that you are taking Nu-Seals 300 if you are to have a urine test, as it can sometimes interfere with the results.

Before using 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 other medicines you may have bought).

Do not take Nu-Seals 300 if you are breast-feeding because some of the aspirin may be in your breast milk and could harm your baby.
