  • if you have or have had asthma, with or without nasal polyps, after taking acetylsalicylic acid.
  • if you are being treated with blood coagulation medications (oral anticoagulants)

  • if you are going to undergo surgery, including dental surgery, in the next seven days.
  • if you are taking anti-inflammatory drugs or other types of medications, as certain medications can interact with Tromalyt 300 mg and produce unwanted effects (see "Use of other medications")

Renal and hepatic insufficiency

This medicine should not be used in patients with renal or hepatic insufficiency.

Children

This medicine should not be administered to children under 16 years old, unless explicitly indicated by a doctor. The use of acetylsalicylic acid in children under 16 years old is related to the appearance of Reye's syndrome, a rare but serious disease.

Elderly

No dose reduction is necessary in elderly patients.

Use of Tromalyt 300 mg with other medications:

Inform your doctor or pharmacist if you are using or have recently used or may need to use another medication, including medications purchased without a prescription, homeopathic products, herbal remedies, 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:

  • Medications used to prevent transplant rejection (cyclosporine and tacrolimus).
  • High blood pressure (diuretics and ACE inhibitors).
  • Cancer, rheumatoid arthritis (methotrexate).
  • Other analgesics or non-steroidal anti-inflammatory drugs (medications used to treat pain and/or muscle inflammation).
  • Anticoagulants (medications used to "thin" the blood and prevent the formation of clots) such as warfarin.
  • Medications used to treat gout (probenecid).
  • Corticosteroids, as they may increase the risk of gastric bleeding
  • Diuretics.
  • Certain antidepressants, such as selective serotonin reuptake inhibitors, as they increase the risk of bleeding.
  • Certain medications for controlling high blood pressure.
  • Medications to lower blood sugar levels
  • Vancomycin, an antibiotic used in some infections).
  • Interferon alpha.
  • Lithium, used in some psychiatric diseases.
  • Antacids.
  • Digoxin, used in heart problems.
  • Barbiturates, medications used as sedatives for sleep problems and to treat convulsions.
  • Zidovudine, used in the treatment of HIV infections.
  • Phenytoin and valproic acid, medications for epilepsy.

If administered together, metamizole (a substance to reduce pain and fever) may reduce the effect of acetylsalicylic acid on platelet aggregation (blood cells stick together and form a blood clot). Therefore, this combination should be used with caution in patients taking low doses of acetylsalicylic acid as a cardioprotector.

Interference with diagnostic tests:

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

Taking Tromalyt 300 mg with food, drinks, and alcohol:

Take this medicine after meals or with some food and with sufficient liquid.

If you habitually consume large amounts of alcohol (three or more alcoholic beverages - beer, wine, liquor, etc. per day), taking this medicine may cause gastric bleeding.

Pregnancy, breastfeeding, and fertility

Consult your doctor or pharmacist before using any medication.

Tromalyt 300 mg should only be used during the first and second trimester of pregnancy unless it is strictly necessary and at the lowest possible doses, and the treatment time should be reduced to the minimum possible.

During the third trimester of pregnancy, it is contraindicated

If you continue or start treatment with Tromalyt 300 mg during pregnancy on the advice of your doctor, then use Tromalyt 300 mg according to your doctor's instructions and do not use a dose higher than recommended.

Pregnancy - last trimester

Do not take more than 100 mg per day if you are in the last three months of pregnancy, as it may harm the fetus or cause problems during delivery. It may cause kidney and heart problems in the fetus. It may affect your tendency to bleed and that of your baby and cause the delivery to be delayed or prolonged more than expected.

If you take Tromalyt 300 mg at low doses (up to 100 mg per day inclusive), you will need strict obstetric control as indicated by your doctor.

Pregnancy - first and second trimester

Do not take Tromalyt 300 mg during the first six months of pregnancy unless it is absolutely necessary and advised by your doctor. If you need treatment during this period or while trying to become pregnant, the lowest dose should be used for the shortest possible time. If taken for more than a few days from the 20th week of pregnancy, Tromalyt 300 mg may cause kidney problems in the fetus, which can lead to low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart.

If you need treatment for more than a few days, your doctor may recommend additional checks.

It is excreted in breast milk, so its use is not recommended during the breastfeeding period due to the risk of adverse effects in the child.
