Warnings and Precautions
Consult your doctor or pharmacist before starting to take paracetamol:

- if you have kidney problems;
- if you have a deficiency of glucose-6-phosphate dehydrogenase;
- if you have anorexia, bulimia, cachexia, or chronic malnutrition;
- if you suffer from dehydration or hypovolemia;
- if you are taking a medication to treat epilepsy, you should consult your doctor before taking this medication, because when used at the same time, it decreases the effectiveness and increases the hepatotoxicity of paracetamol, especially in treatments with high doses of paracetamol (see below in this section)
- if you have Gilbert's disease (also known as Meulengracht's disease);
- if you have heart, respiratory, or anemia failure; in these situations, administration should be carried out under surveillance and only for short periods;
- - if you have asthma and are sensitive to acetylsalicylic acid;
- - Paracetamol can cause severe skin reactions, such as acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Patients should be informed about the signs of severe skin reactions and the use of the medication should be discontinued at the first sign of skin rash or any other sign of hypersensitivity.
- The total dose of paracetamol should not exceed 3 g per day.
- Concomitant use of this medication with other medications containing paracetamol, such as flu and cold medications, should be avoided, as high doses can cause liver damage. Do not use more than one medication containing paracetamol without consulting your doctor. If an overdose occurs, seek medical attention immediately (see "If you take more than you should").
- Chronic alcoholics should be careful not to take more than 2 grams of paracetamol in 24 hours.
If the pain persists for more than 5 days, the fever for more than 3 days, or the pain or fever worsens or other symptoms appear, the clinical situation should be evaluated by your doctor. This medication should not be used for self-medication of high fever (over 39°C), fever lasting more than 3 days, or recurrent fever, unless indicated by your doctor, as these situations may require medical evaluation and treatment.
The administration of paracetamol doses higher than recommended implies a very serious risk of liver injury. Medications containing paracetamol should not be taken for more than a few days or in high doses unless indicated by your doctor.
Prolonged use of analgesics or inadequate use of high doses can cause headaches, which should not be treated with higher doses of the medication.

- If you have severe diseases, such as severe renal insufficiency or sepsis (when bacteria and their toxins circulate in the blood, causing organ damage), or if you have malnutrition, chronic alcoholism, or are also taking flucloxacillin (an antibiotic). A severe disease called metabolic acidosis (an anomaly in 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. The symptoms of metabolic acidosis may include: severe breathing difficulties with deep and rapid breathing, drowsiness, feeling unwell (nausea) and vomiting.

Inform your doctor or pharmacist if you are taking:
