1. What Aspirin C is and what it is used for

Aspirin C contains acetylsalicylic acid, which has analgesic, anti-inflammatory, and antipyretic effects, as well as vitamin C, which is beneficial in the course of colds, during which there is an increased need for vitamin C.

Indications for use:

Symptomatic treatment of mild to moderate pain (e.g., headaches, toothaches, muscle aches).
Symptomatic treatment of pain and fever in the course of colds and flu.

2. Important information before taking Aspirin C

When not to take Aspirin C:

• if the patient is allergic to the active substances, 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 triggered by 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,
• if the patient has a history of kidney stones,
• if the patient has increased oxalate excretion in the urine,
• if the patient has hemochromatosis.

Warnings and precautions

Before starting treatment with Aspirin C, 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,
• if the patient is taking anticoagulant medications,
• if the patient has impaired liver function,
• if the patient has impaired kidney function or circulatory disorders (e.g., kidney vessel disease, congestive heart failure, reduced 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 a history of (chronic or recurrent) stomach ulcers or gastrointestinal bleeding,
• if the patient has a genetic disorder characterized by a deficiency of the enzyme - glucose-6-phosphate dehydrogenase, as acetylsalicylic acid may cause hemolysis or hemolytic anemia,
• if the patient is breastfeeding.

Aspirin C should not be taken by women in 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 C.
Acetylsalicylic acid, even in small doses, reduces uric acid excretion from the body. In patients with a tendency to reduced uric acid excretion, the medicine may cause a gout attack.
In the course of certain 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. 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, medicines containing acetylsalicylic acid should not be used, and in adolescents over 12 years of age, medicines containing acetylsalicylic acid can only be used on a doctor's prescription.
In patients with calcium oxalate kidney stones or recurrent kidney stones, special caution is recommended when consuming ascorbic acid.
Long-term use of medicines containing acetylsalicylic acid may cause headaches that worsen with each subsequent dose.
Long-term use of painkillers, especially those containing multiple active substances, may lead to severe kidney function disorders and kidney failure.

Aspirin C and other medicines

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

• the toxic effect of methotrexate on the bone marrow; acetylsalicylic acid should not be taken 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, thrombolytic (dissolving blood clots), and antiplatelet medications, which may increase the risk of prolonged bleeding time and bleeding;
• the risk of stomach ulcers and gastrointestinal bleeding if taken concurrently with corticosteroids, other non-steroidal anti-inflammatory drugs, including other salicylates, or if alcohol is consumed during treatment; after stopping systemic glucocorticoids (except for hydrocortisone used as replacement therapy in Addison's disease), the risk of salicylate overdose increases;
• the effect of digoxin (a medicine used in heart diseases), as it increases its concentration in the blood;
• the effect of antidiabetic medicines, such as insulin, sulfonylurea derivatives;
• the toxic effect of valproic acid (a medicine used in epilepsy), which in turn enhances the antiplatelet effect of acetylsalicylic acid;
• the effect of selective serotonin reuptake inhibitors (antidepressants). Special caution should be exercised when taking Aspirin C with the following medicines, as acetylsalicylic acid weakens:
• the effect of uricosuric medicines used to treat gout (e.g., benzbromarone, probenecid), which may worsen gout symptoms;
• the effect of diuretics;
• the effect of certain antihypertensive medicines (from the group of so-called angiotensin-converting enzyme inhibitors).

Aspirin C can be taken with the above-mentioned medicines (except for methotrexate at doses of 15 mg per week or higher) only after consulting a doctor.
Concurrent use of deferiprone with ascorbic acid may increase tissue iron toxicity, especially in the heart, leading to its failure.

Aspirin C with food, drinks, and alcohol:

See section 3 of the leaflet.
Warning! Alcohol may increase the risk of gastrointestinal side effects, such as stomach ulcers or bleeding.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult a doctor or pharmacist before taking this medicine.
Pregnancy
Aspirin C should not be taken during the last 3 months of pregnancy, as it may harm the unborn child or cause complications during delivery. The medicine may cause kidney and heart function disorders in the unborn child. It may also affect the patient's and child's tendency to bleed and cause delayed or prolonged delivery. Aspirin C should not be taken during the first 6 months of pregnancy, unless it is absolutely necessary and prescribed by a doctor. If the patient requires treatment during this period or is trying to conceive, they should use the smallest possible dose for the shortest possible time. If Aspirin C is taken for more than a few days from the 20th week of pregnancy, it may cause kidney function disorders in the unborn child, leading to reduced amniotic fluid (oligohydramnios) or narrowing of the arterial duct in the child's heart. If treatment is necessary for more than a few days, the doctor may recommend additional monitoring.
Breastfeeding
Acetylsalicylic acid and vitamin C pass into breast milk in small amounts.
Fertility
Aspirin C belongs to a group of medicines that may adversely affect female fertility.
This effect is temporary and disappears after the end of therapy.

Driving and using machines

The medicine does not affect the ability to drive vehicles or operate machines.

Aspirin C contains sodium

One effervescent tablet contains 467 mg of sodium (the main component of table salt). This corresponds to 23% of the maximum recommended daily sodium intake in the diet for adults. The maximum daily dose of this product is equivalent to 187% of the WHO-recommended maximum daily sodium intake.
This should be taken into account in patients with reduced kidney function and in patients controlling their sodium intake.

Laboratory tests

Vitamin C may interact chemically during laboratory tests, including affecting glucose measurements in urine and blood, leading to false results, although it does not affect blood glucose levels.

3. How to take Aspirin C

This medicine should always be used exactly as described in the patient leaflet or as directed by a doctor or pharmacist. In case of doubt, you should consult a doctor or pharmacist.
The recommended dose of Aspirin C is:

• adults: 1-2 effervescent tablets (i.e., 400-800 mg of acetylsalicylic acid and 240-480 mg of ascorbic acid) at a time. If necessary, the single dose may be repeated at intervals of no less than 4 to 8 hours. Do not take more than 8 tablets per day (i.e., 3200 mg of acetylsalicylic acid and 1920 mg of ascorbic acid).
• adolescents over 12 years of age, only on a doctor's prescription: 1 tablet (i.e., 400 mg of acetylsalicylic acid and 240 mg of ascorbic acid) at a time. If necessary, the single dose may be repeated at intervals of no less than 4 to 8 hours. Do not take more than 3 tablets per day (i.e., 1200 mg of acetylsalicylic acid and 720 mg of ascorbic acid). The medicine should not be taken for more than 3-5 days without consulting a doctor.

The effervescent tablets should be dissolved in a glass of water and the effervescent liquid should be drunk. Take after meals.

Taking a higher dose of Aspirin C than recommended

Aspirin C poisoning can be caused by prolonged 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, deep breathing, and symptoms of respiratory alkalosis (darkness 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), heart and blood vessel disorders (from irregular heartbeat, low blood pressure to cardiac arrest), fluid and electrolyte loss (from dehydration, oliguria [reduced urine output below 400-500 ml per day in adults] to kidney failure), increased or decreased blood glucose levels (especially in children), ketoacidosis, gastrointestinal bleeding, blood coagulation disorders, and neurological disorders manifesting as lethargy, confusion, and coma or convulsions.
In the event of an overdose, 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.
Generally, symptoms of vitamin C overdose may include gastrointestinal disorders, such as diarrhea, nausea, and vomiting. If symptoms of overdose occur, the product should be discontinued, and a doctor or pharmacist should be consulted.
Acute or chronic overdose of vitamin C (>2 g/day in adults) may cause a significant increase in oxalate levels in the urine. In some cases, this leads to hyperoxaluria, calcium oxalate crystallization, kidney stone formation, calcium oxalate deposition, and acute kidney failure.
Vitamin C overdose in people with glucose-6-phosphate dehydrogenase deficiency (>3 g/day in children and >15 g/day in adults) may lead to hemolysis of red blood cells.

Missing a dose of Aspirin C

In the event of a missed dose and persistence of symptoms, the next dose of Aspirin C should be taken. A double dose should not be taken to make up for the missed dose.

Stopping treatment with Aspirin C

In case of any further doubts about the use of this medicine, you should consult a doctor or pharmacist.
