  • you have asthma,
  • you have nasal polyps associated with asthma that are produced or increased by acetylsalicylic acid,
  • you have hemophilia or other blood coagulation problems,
  • you are being treated with oral anticoagulant medications,

  • you are under 16 years of age, as the use of acetylsalicylic acid has been linked to Reye's Syndrome, a rare but serious disease,
  • you are in your third trimester of pregnancy.

Be careful with Aspirin

You should consult your doctor if you need this medicine:

  • if you have high blood pressure, or have reduced kidney, heart, or liver function, or have blood coagulation disorders,
  • if you have had stomach or intestinal ulcers,
  • if you are being treated with anticoagulants, you should consult your doctor before taking this medicine,
  • if you are taking anti-inflammatory medications or other types of medications, as certain medications can interact with Aspirin 500 mg granules and produce undesirable effects (see "Use of other medications"),
  • if you are allergic to other anti-inflammatory or antirheumatic medications,
  • if you have a glucose-6-phosphate dehydrogenase deficiency,
  • if you have had rhinitis or urticaria,
  • if you have recently undergone or are to undergo surgery in the next 7 days, including dental surgery,
  • if you are in your first or second trimester of pregnancy,
  • do not systematically administer to prevent possible discomfort caused by vaccinations.

Other medications and Aspirin

Tell your doctor or pharmacist if you are using or have recently used other medications, including those obtained without a prescription, homeopathic, herbal, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.

This is especially important in the case of:

  • other analgesics or non-steroidal anti-inflammatory medications (medicines used to treat pain and/or muscle inflammation),
  • certain antidepressants, such as selective serotonin reuptake inhibitors, as they increase the risk of bleeding,
  • anticoagulants (medicines used to "thin" the blood and prevent the formation of clots), such as warfarin,
  • oral antidiabetics (medicines to lower blood sugar levels),
  • barbiturates (medicines used to treat convulsions),
  • beta-blockers (medicines for blood pressure control),
  • cimetidine and ranitidine (used for stomach acidity),
  • medicines used to prevent transplant rejection (cyclosporine and tacrolimus),
  • corticosteroids, as they can increase the risk of gastrointestinal bleeding,
  • digoxin (heart medication),
  • high blood pressure (diuretics and ACE inhibitors),
  • phenytoin and valproic acid (antiepileptics),
  • interferon alpha (used to treat certain viral and tumor infections),
  • lithium (used in certain psychiatric illnesses),
  • cancer or rheumatoid arthritis (methotrexate),
  • medicines used to treat gout (probenecid),
  • vancomycin (antibiotic used for infections),
  • zidovudine (used in the treatment of patients infected with the human immunodeficiency virus, the cause of AIDS).

Interference with diagnostic tests

If you are going to have any diagnostic tests (including blood or urine tests), tell your doctor that you are taking this medicine, as it may alter the results.

Taking Aspirin with food, drinks, and alcohol

Take this medicine after meals or with some food.

If you regularly consume alcohol (three or more alcoholic beverages - beer, wine, liquor, ... - per day), taking Aspirin may cause stomach bleeding.

Pregnancy

Consult your doctor or pharmacist before using any medication.

If you are pregnant or think you may be pregnant, consult your doctor before taking this medicine.

Pregnancy - last trimester

Do not take Aspirin if you are in the last 3 months of pregnancy, as it may harm the fetus or cause problems during delivery. This medicine can cause kidney and heart problems in the fetus. It may affect your tendency to bleed and that of your baby, causing a possible delay in delivery or prolonging it more than expected.

Pregnancy - first and second trimester

Do not take Aspirin during the first 6 months of pregnancy unless it is absolutely necessary and your doctor advises you to do so. If you need treatment during this period or while trying to become pregnant, the dose will be limited to the lowest possible during the shortest time possible.

If you take Aspirin for several days from the 20th week of pregnancy, it may cause kidney problems in the fetus that could lead to low levels of amniotic fluid (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for several days, your doctor may recommend additional monitoring.

Breastfeeding

Consult your doctor or pharmacist before using any medication.

Women who are breastfeeding should consult their doctor before using this medicine, as acetylsalicylic acid passes into breast milk.

Use in children

Do not administer to children under 16 years of age.

Use in adults over 65 years of age

Older adults should not take this medicine without consulting their doctor, as they are more likely to experience side effects.

Driving and using machines

No effects on the ability to drive or use machines have been described.

Aspirin contains phenylalanine and sodium

This medicine contains 5 mg of aspartame in each sachet. Aspartame is a source of phenylalanine that may be harmful in case of phenylketonuria (PKU), a rare genetic disease in which phenylalanine accumulates because the body is unable to eliminate it properly.

This medicine contains less than 1 mmol of sodium (23 mg) per sachet; it is essentially "sodium-free".

3. How to take Aspirin

Patient with reduced liver or kidney function: consult your doctor, as the dose should be reduced.

The granules should be placed directly on the tongue. They disperse in saliva before swallowing, so it is not necessary to take them with water.

Take the medicine with meals or with some food, especially if you experience digestive discomfort.

Do not take this medicine on an empty stomach.

Always use the lowest effective dose.

The administration of this preparation is subject to the appearance of painful or febrile symptoms. As they disappear, this medication should be discontinued.

If the pain persists for more than 5 days, or the fever for more than 3 days, or the symptoms worsen or other symptoms appear, you should interrupt treatment and consult your doctor.
