1. What is Acetylsalicylic Acid Stada and what is it used for

Acetylsalicylic acid, at the dose present in this medicine, belongs to the group of medicines called platelet aggregation inhibitors. Platelets are components of the blood, smaller than red and white blood cells, that aggregate when the blood clots. By preventing this aggregation, platelet aggregation inhibitors reduce the possibility of blood clots (thrombi) forming. Your doctor has prescribed acetylsalicylic acid to prevent the formation of thrombi and reduce the risk of obstruction of your arteries, as:

• You have previously suffered a myocardial infarction or angina pectoris.
• You have suffered a non-hemorrhagic transient or permanent stroke.
• You have undergone surgical intervention, such as coronary angioplasty or coronary bypass.

2. What you need to know before taking Acetylsalicylic Acid Stada

Do not take Acetylsalicylic Acid Stada

• if you are allergic to acetylsalicylic acid or any of the other components of this medicine (listed in section 6).
• if you have or have had asthma, with or without nasal polyps, after taking acetylsalicylic acid.
• if you have presented allergic reactions of an asthmatic type (difficulty breathing, shortness of breath, bronchospasm, and in some cases cough or wheezing) when taking anti-inflammatory drugs, acetylsalicylic acid, or other analgesics, as well as the dye tartrazine.
• if you have or have had acute gastroduodenal ulcer or recurring gastric discomfort.
• if you have a history of bleeding or gastric perforation after treatment with acetylsalicylic acid or other non-steroidal anti-inflammatory drugs.
• if you have hemophilia or other blood coagulation problems that predispose you to internal bleeding.
• if you have severe kidney and/or liver disease (severe renal and/or hepatic insufficiency).
• if you are being treated with blood coagulation drugs (oral anticoagulants).
• if you have severe heart disease.
• if you are being treated with methotrexate.
• if you are under 16 years old, unless explicitly indicated by your doctor, as the use of acetylsalicylic acid is related to the onset of Reye's syndrome, a rare but serious disease.
• if you are in your third trimester of pregnancy.

Warnings and precautions

Tell your doctor before taking acetylsalicylic acid if you are in any of the following situations:

• you have recently undergone surgery, including dental surgery.
• you are going to undergo surgery, including dental surgery, in the next seven days.
• you are taking non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen, or other types of medications, as certain medications can interact with acetylsalicylic acid and produce unwanted effects (see "Taking Acetylsalicylic Acid Stada with other medicines").
• you are being treated with corticosteroids.
• you are being treated with antidepressants.
• you are being treated with platelet aggregation inhibitors.
• you have high blood pressure or serious kidney, heart, or liver problems, have blood coagulation disorders, or are being treated with anticoagulants.
• you are allergic to other anti-inflammatory or anti-rheumatic drugs.
• you have a deficiency of glucose-6-phosphate dehydrogenase.
• you have rhinitis and/or urticaria.
• you have suffered or suffer from gout attacks.

Acetylsalicylic acid may cause bronchospasm, asthmatic attacks, or other hypersensitivity reactions. Risk factors are: pre-existing asthma, hay fever, nasal polyps, or chronic respiratory insufficiency, and also in patients with other allergic manifestations, such as skin reactions, itching, or urticaria.

Taking Acetylsalicylic Acid Stada with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.

Certain medicines may interact with acetylsalicylic acid, so they should not be used without consulting your doctor. This is especially important in the case of:

• Analgesics and non-steroidal anti-inflammatory drugs, such as ibuprofen or naproxen, used to treat muscle pain and/or inflammation.
• Glucocorticoids, except for hydrocortisone used in Addison's disease, as they may increase the risk of gastrointestinal bleeding and ulcers.
• Diuretics.
• Some antidepressants, such as selective serotonin reuptake inhibitors, as they increase the risk of bleeding.
• Blood coagulation drugs (oral anticoagulants), as they increase the risk of bleeding.
• Some medications for controlling high blood pressure.
• Medications to lower blood sugar levels.
• Cyclosporin, used in transplants.
• Vancomycin, an antibiotic used in some infections.
• Interferon alpha.
• Lithium, used in some psychiatric illnesses.
• Methotrexate, used to treat cancer and rheumatoid arthritis: increases the hepatotoxicity of methotrexate.
• Medications used to treat gout.
• 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, metamizol (a substance to reduce pain and fever) may reduce the effect of acetylsalicylic acid on platelet aggregation (blood cells that come 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.

Taking Acetylsalicylic Acid Stada with food and drinks

Take this medicine with a glass of water, preferably on an empty stomach and at least 1 hour before meals.

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

Pregnancy, breastfeeding, and fertility

Pregnancy

Consult your doctor or pharmacist before using any medicine.

Pregnancy - last trimester

Do not take acetylsalicylic acid 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 your fetus. It may affect your and your baby's tendency to bleed and delay or prolong labor more than expected.

Pregnancy - first and second trimester

Do not take acetylsalicylic acid during the first six months of pregnancy unless absolutely necessary and as indicated by your doctor. If you need treatment during this period or while trying to become pregnant, you should take the minimum dose for the shortest possible time. From the 20th week of pregnancy, if taken for more than a few days, acetylsalicylic acid may cause kidney problems in your fetus, which may 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 during a period of more than a few days, your doctor may recommend additional checks.

Breastfeeding

Consult your doctor or pharmacist before using any medicine.

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

Fertility

Based on the limited published data available, human studies have not shown a consistent effect of acetylsalicylic acid on fertility, and there is no conclusive evidence in animal studies.

Driving and using machines

No effects have been described in this regard.

Acetylsalicylic Acid Stada contains sodium

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

3. How to take Acetylsalicylic Acid Stada

Follow your doctor's instructions for taking this medicine exactly. Take this medicine with a glass of water, preferably on an empty stomach and at least 1 hour before meals. The tablets should not be crushed, broken, or chewed.

Consult your doctor or pharmacist if you have any doubts. The normal dose is one acetylsalicylic acid tablet per day.

Try to take the medicine regularly, every day at the same time.

Your doctor will indicate the duration of treatment with acetylsalicylic acid. Do not stop treatment before.

If you think the effect of acetylsalicylic acid is too strong or too weak, tell your doctor or pharmacist.

Due to its delayed-release formulation, this medicine is not indicated for acute myocardial infarction. However, if it is necessary to use it in an emergency, it is recommended to crush the first tablet or chew it and swallow it to accelerate the absorption of acetylsalicylic acid.
