Acetylsalicylic acid Bluefish – Acetylsalicylic acid uses, dose and side effects


75 mg, 160 mg tablets of
acetylsalicylic acid

1. What Acetylsalicylic acid Bluefish is and what it is used for

Acetylsalicylic acid Bluefish contains the active substance acetylsalicylic acid.

Acetylsalicylic acid Bluefish is a so-called blood thinner, which reduces the risk of blood clots by preventing platelets from clotting.

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

Acetylsalicylic acid contained in Acetylsalicylic acid Bluefish may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

What you need to know before you take Acetylsalicylic acid Bluefish

Do not take Acetylsalicylic acid Bluefish:

  • if you are allergic to the active substance or any of the other ingredients of this medicine, see section 6.
  • if you are allergic to medicines with pain-relieving and anti-inflammatory effects, so-called non-steroidal anti-inflammatory drugs ( NSAIDs )
  • if you have allergic symptoms (eg difficulty breathing, nasal congestion, and runny nose, rash) when taking acetylsalicylic acid or similar anti-inflammatory drugs.
  • if you suffer from stomach ulcers
  • if you have problems with the blood not clotting properly
  • if you have cirrhosis of the liver
  • if you have severe heart failure.

The daily dose of Acetylsalicylic acid Bluefish should not exceed 100 mg during the last three months of pregnancy (see section Pregnancy and lactation).

Warnings and cautions

Talk to your doctor, pharmacist, or nurse before taking Acetylsalicylic acid Bluefish.

Tell your doctor before starting treatment with Acetylsalicylic acid Bluefish:

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

People with asthma, chronic lung disease, hay fever or nasal polyps have an increased risk of hypersensitivity reactions when treated with NSAIDs such as acetylsalicylic acid. Such a reaction may include asthma attacks, swelling of the face, mouth, or throat, difficulty swallowing or difficulty breathing ( angioedema ), and hives.

Other medicines and Acetylsalicylic acid Bluefish

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 Acetylsalicylic acid Bluefish is taken at the same time as certain other medicines for:

  • blood clots (eg warfarin )
  • organ rejection after transplantation (cyclosporine, tacrolimus)
  • high blood pressure (eg diuretics and ACE inhibitors )
  • pain and inflammation (eg corticosteroids and NSAIDs )
  • gout (probenecid)
  • cancer and rheumatoid arthritis (methotrexate)
  • arrhythmias in the heart ( digoxin )
  • manic depressive illness (lithium)
  • epilepsy ( phenytoin and valproic acid )
  • type 2 diabetes (sulphonylurea)
  • high blood fats ( nicotinic acid ).

Metamizole (a substance that reduces pain and fever) can reduce the effect of acetylsalicylic acid on platelet aggregation ( blood cells that attach 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 acetylsalicylic acid for cardiac protection.

Acetylsalicylic acid Bluefish with food, drink, and alcohol

Acetylsalicylic acid Bluefish in combination with alcohol may increase the risk of gastrointestinal bleeding.

Pregnancy and breastfeeding

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.

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

Acetylsalicylic acid passes into breast milk but is unlikely to affect breastfed infants. However, talk to your doctor if you use Acetylsalicylic acid Bluefish more than occasionally during breast-feeding.

Acetylsalicylic acid Bluefish, like many anti-inflammatory drugs (so-called NSAIDs ), can make it more difficult to get pregnant and is therefore not recommended for women trying to conceive.
