1. What is Aspirin and what is it used for

Aspirin contains acetylsalicylic acid, which has analgesic, anti-inflammatory, and antipyretic effects.
Indications for use:

• mild or moderate pain,
• fever.

2. Important information before taking Aspirin

When not to take Aspirin:

• if the patient is allergic to the active substance - acetylsalicylic acid, other salicylates, or any of the other ingredients of this medicine (listed in section 6),
• if the patient has a bleeding disorder,
• if the patient has acute stomach or duodenal ulcer,
• if the patient has severe heart failure or severe liver or kidney failure,
• if the patient has ever had asthma attacks caused by taking salicylates or substances with similar effects, especially non-steroidal anti-inflammatory drugs,
• if the patient is taking methotrexate (used in cancer treatment) at doses of 15 mg per week or higher,
• if the patient is in the third trimester of pregnancy,
• in children under 12 years of age.

Warnings and precautions

Before starting Aspirin, you should discuss it with your doctor or pharmacist:

• if the patient is hypersensitive to non-steroidal anti-inflammatory and anti-rheumatic drugs or other allergenic substances,

and

• if the patient is taking anticoagulant medications,
• if the patient has impaired liver function,
• if the patient has kidney function disorders or circulatory disorders (e.g., kidney vessel disease, congestive heart failure, decreased blood volume, extensive surgery, sepsis, severe bleeding), as acetylsalicylic acid may further increase the risk of kidney function disorders and severe kidney failure,
• if the patient has had a history of (chronic or recurrent) stomach ulcers or gastrointestinal bleeding,
• if the patient has a genetic disorder involving a deficiency of the enzyme - glucose-6-phosphate dehydrogenase, as acetylsalicylic acid may cause hemolysis or hemolytic anemia,
• if the patient is breastfeeding.

Acetylsalicylic acid should not be used in women during the first and second trimester of pregnancy, unless it is absolutely necessary.
Acetylsalicylic acid may cause bronchospasm and trigger asthma attacks or other hypersensitivity reactions. Patients with asthma, chronic respiratory diseases, hay fever, nasal polyps, and those who experience allergic reactions to other substances (e.g., skin reactions, itching, hives) are particularly at risk.
Patients undergoing surgical procedures (including minor procedures, e.g., tooth extraction) should inform their doctor about taking Aspirin.
Acetylsalicylic acid, even in small doses, reduces the excretion of uric acid from the body. In patients with a tendency to reduced uric acid excretion, the medicine may cause a gout attack.
In the course of some viral diseases, especially in the case of influenza A or B virus infection or chickenpox, mainly in children and adolescents, there is a risk of developing Reye's syndrome - a rare but life-threatening disease. The occurrence of persistent vomiting during infection may indicate the development of Reye's syndrome, which requires immediate medical attention.
The risk of developing Reye's syndrome during viral infections may increase if acetylsalicylic acid is administered at the same time, although a causal relationship has not been proven.
For these reasons, in children under 12 years of age, medications containing acetylsalicylic acid should not be used, and in adolescents over 12 years of age, medications containing acetylsalicylic acid can only be used on a doctor's prescription.
Long-term use of medications containing acetylsalicylic acid may cause headaches that worsen during subsequent doses.
Long-term use of painkillers, especially those containing multiple active substances, may lead to severe kidney function disorders and kidney failure.

Aspirin and other medicines

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
You should exercise special caution when taking Aspirin with the following medicines, as acetylsalicylic acid enhances:

• the toxic effect of methotrexate on the bone marrow; acetylsalicylic acid should not be used at the same time as methotrexate at doses of 15 mg per week or higher; concurrent use of methotrexate at doses less than 15 mg per week requires special caution;
• the effect of anticoagulant medications, thrombolytic medications (dissolving blood clots), and medications that inhibit platelet aggregation, which may increase the risk of prolonged bleeding time and bleeding;

and

• the risk of stomach ulcers and gastrointestinal bleeding if used concurrently with corticosteroids, other non-steroidal anti-inflammatory drugs, including other salicylates, or if alcohol is consumed during treatment;
• the effect of digoxin (a medicine used to treat heart conditions), as it increases its concentration in the blood;
• the effect of anti-diabetic medications, e.g., insulin, sulfonylurea derivatives;
• the toxic effect of valproic acid (a medicine used in epilepsy), which in turn enhances the anti-aggregatory effect of acetylsalicylic acid;
• the effect of selective serotonin reuptake inhibitors (antidepressant medications). You should exercise special caution when taking Aspirin with the following medicines, as acetylsalicylic acid weakens:
• the effect of anti-gout medications used to treat gout, which increase uric acid excretion from the body (e.g., benzbromarone, probenecid), which may worsen gout symptoms;
• the effect of diuretic medications; certain anti-hypertensive medications (from the group of so-called angiotensin-converting enzyme inhibitors).

Aspirin can be used with the above-mentioned medicines (except for methotrexate at doses of 15 mg per week or higher) only after consulting a doctor.

Aspirin with food, drink, or alcohol

See section 3 of the leaflet.
Warning! Alcohol may increase the risk of adverse reactions from the gastrointestinal tract, i.e., mucosal ulceration or bleeding.

Pregnancy, breastfeeding, and fertility

In pregnancy, breastfeeding, or if you suspect you are pregnant, or if you plan to become pregnant, you should consult your doctor or pharmacist before taking the medicine.
Aspirin is contraindicated in the third trimester of pregnancy, as it may cause complications during the perinatal period, both in the mother and the newborn. Medications containing acetylsalicylic acid should not be used in women during the first and second trimester of pregnancy, unless it is absolutely necessary. If it is necessary to use acetylsalicylic acid in women trying to conceive or in the first and second trimester of pregnancy, the smallest possible dose of the medicine should be taken for the shortest possible time.
Aspirin belongs to a group of medicines that may adversely affect female fertility. This effect is temporary and disappears after the end of therapy.
Acetylsalicylic acid passes into breast milk in small amounts.

Driving and using machines

The medicine does not affect the ability to drive vehicles and operate machinery.

Tablets should be taken orally, after meals, with a large amount of water.

Taking a higher dose of Aspirin than recommended

Poisoning with the active substance of Aspirin can be caused by long-term use of the medicine (mild poisoning) or overdose (severe poisoning), which can be life-threatening, e.g., after accidental ingestion by children or the elderly.
Symptoms of mild poisoning are: dizziness (including vertigo), tinnitus, deafness, excessive sweating, nausea, and vomiting, headache, confusion (disorders of consciousness with disorientation, thinking, and speech disorders, delusions, hallucinations, anxiety, and psychomotor agitation), rapid breathing, too deep breathing, and symptoms of respiratory alkalosis (spots before the eyes, fainting).
In the case of severe poisoning, the following may also occur: high fever, respiratory disorders (up to respiratory arrest and suffocation), cardiac and vascular disorders (from irregular heartbeat, low blood pressure to cardiac arrest), fluid and electrolyte loss (from dehydration, oliguria [reduced urine output below 400-500 ml in adults] to kidney failure), increased or decreased blood glucose levels (especially in children), ketoacidosis, gastrointestinal bleeding, blood coagulation disorders, neurological disorders manifesting as lethargy, confusion, and up to coma and convulsions.
In the event of taking a higher dose of the medicine than recommended, you should immediately consult a doctor or pharmacist, and in the case of severe poisoning, the patient should be taken to the hospital immediately.
Treatment of poisoning involves gastric lavage, administration of activated charcoal, and alkaline diuresis. In severe cases, forced alkaline diuresis, peritoneal dialysis, or hemodialysis may be necessary.

Missing a dose of Aspirin

In the event of missing a dose and persistence of symptoms, you should take the next dose of Aspirin. You should not take a double dose to make up for the missed dose.

Stopping Aspirin treatment

In case of any further doubts related to the use of this medicine, you should consult your doctor or pharmacist.
