Trombyl – Acetylsalicylic Acid Uses, Dose And Side Effects


Trombyl 75 mg or 160 mg tablets of Acetylsalicylic Acid

What Trombyl Is And What It Is Used For?

Thrombyl is a so-called blood thinner, which reduces the risk of blood clot formation by preventing platelets from clumping together.

Trombyl medication is used by patients who have severe angina pectoris ( unstable angina pectoris) or who have previously suffered a heart or brain infarction ( stroke ). Thrombyl helps to reduce the risk of recurrence of a new heart attack by preventing clots from forming in the blood vessels of the heart and brain.

What You Need To Know Before Using Trombyl

Do Not Use Trombyl

  • If you are allergic to acetylsalicylic acid, other medicines with pain-relieving and anti-inflammatory effects (so-called non-steroidal anti-inflammatory agents), or any other ingredient in this medicine (listed in section 6).
  • If you have had allergic symptoms (e.g. breathing difficulties, nasal congestion and runny nose, skin rash) when you have taken acetylsalicylic acid or similar anti-inflammatory agents.
  • If you suffer from stomach ulcers.
  • If you have hemophilia.
  • If you have a deficiency of the platelets that help to clot the blood.
  • If you have cirrhosis
  • If you have severe heart failure.

The daily dose of Trombyl must not exceed 100 mg during the last three months of pregnancy (see section Pregnancy and breastfeeding).

Warnings And Precautions

Talk to your doctor or pharmacist before taking Trombyl.

Inform the doctor before starting treatment with Trombyl:

  • If you are treated with medicines that prevent the formation of blood clots or are diuretics
  • If you have gastrointestinal disease
  • If you have heart failure
  • If you have kidney or liver disease.

People with bronchial asthma, chronic lung disease, hay fever or nasal polyps have an increased risk of hypersensitivity reaction.

You must seek medical attention immediately if your symptoms worsen or if you experience severe or unexpected side effects, e.g. unusual bleeding, severe skin rash, or other signs of severe allergy (see section “Possible side effects”).

Other Medicines And Trombyl

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

The effect of the treatment can be affected if Trombyl medication is taken at the same time as certain other medicines against:

  • Blood clots (eg warfarin)
  • Rejection of organs after transplantation
    • Ciclosporin
    • Tacrolimus
  • High blood pressure e.g. 
    • Diuretics
    • ACE inhibitors 
  • Pain and inflammation e.g. 
    • Corticosteroids
    • NSAIDs 
  • Gout 
    • Probenecid
  • Cancer and rheumatoid arthritis 
    • Methotrexate
  • Heart rhythm disturbances
    • Digoxin 
  • Manic depressive disorder
    • Lithium
  • Epilepsy 
    • Phenytoin
    • Valproic acid 
  • Diabetes type II
    • Sulphonylureas
  • High blood fats
    • Nicotinic acid 
  • Pain and fever (metamizole). Metamizole can reduce the effect of aspirin on platelet aggregation ( blood cells that stick together and form a blood clot) when taken at the same time. Therefore, this combination should be used with caution in patients taking a low dose of aspirin for cardioprotection.

Trombyl With Food, Drink, And Alcohol

Thrombyl in combination with alcohol can increase the risk of bleeding in the gastrointestinal tract.

Pregnancy, Breastfeeding, And Fertility

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

Pregnant women should not take acetylsalicylic acid during pregnancy unless prescribed by a doctor. The daily dose must not exceed 100 mg during the last three months of pregnancy (see section Do not take Trombyl). Regular or high doses of this drug during late pregnancy can cause serious complications for the mother and baby.

Acetylsalicylic acid passes into breast milk but probably does not affect children who are breastfed. However, talk to your doctor if you use Trombyl more than occasionally during breastfeeding.

Trombyl, like many anti-inflammatory drugs (so-called NSAIDs ), can make it difficult to get pregnant and is therefore not recommended for women who are trying to get pregnant.

Driving Ability And Use Of Machinery

Trombyl has no known effects on the ability to drive and use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.
