  • Do not take more medication than recommended in section 3. How to take Paracetamol Alter 1 g tablets.
  • Avoid taking this medication simultaneously with other medications that contain paracetamol, such as flu and cold medications, as high doses can lead to liver damage. Do not use more than one medication that contains paracetamol without consulting your doctor.

  • Patient with kidney, liver, heart, or lung disease, and patients with anemia, should consult their doctor before taking this medication.

  • Asthmatic patients sensitive to acetylsalicylic acid should consult their doctor before taking this medication.
  • If you have severe diseases, such as severe renal failure or sepsis (when bacteria and their toxins circulate in the blood, causing damage to organs), or if you suffer from malnutrition, chronic alcoholism, or are also taking flucloxacillin (an antibiotic). A serious disease called metabolic acidosis (an anomaly in the blood and fluids) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken with flucloxacillin. Symptoms of metabolic acidosis may include: severe breathing difficulties with deep and rapid breathing, drowsiness, feeling of discomfort (nausea) and vomiting.

This medication is taken orally.

The tablets should be swallowed whole or broken in half, with the help of a glass of liquid, preferably water.

The tablets are scored, which allows them to be broken in half. The score serves only to break the tablet if it is difficult to swallow whole, not to administer 500 mg doses, as there are other presentations available with this amount of active ingredient.

Always use the lowest effective dose.

High daily doses of paracetamol should be avoided during prolonged periods, as the risk of side effects such as liver damage increases.

The administration of this medication is subject to the appearance of pain or fever. As they disappear, treatment should be discontinued.

If the pain persists for more than 5 days, the fever for more than 3 days, or the pain or fever worsen or other symptoms appear, treatment should be interrupted and your doctor consulted.

In case of overdose or accidental ingestion, go immediately to a medical center or call the Toxicology Information Service (telephone 91 562 04 20), indicating the medication and the amount ingested.

Symptoms of overdose may be: dizziness, vomiting, loss of appetite, yellowing of the skin and eyes (jaundice), and abdominal pain and pancreatitis (inflammation of the pancreas).

If you have ingested an overdose, you should go immediately to a medical center, even if you do not notice symptoms, as they often do not appear until 3 days after ingestion, even in cases of severe poisoning.

Treatment of overdose is more effective if started within 4 hours after ingestion of the medication.

Patient treated with barbiturates or chronic alcoholics may be more susceptible to the toxicity of a paracetamol overdose.

If you forget to take Paracetamol Alter

Do not take a double dose to make up for forgotten doses, simply take the forgotten dose when you remember, taking the following doses with the indicated interval between doses (at least 4 hours).
