Paracetamol is effective for reducing pain and fever.

If you are allergic to paracetamol or any of the other components of this medicine (listed in section 6).
Warnings and precautions
Consult your doctor or pharmacist before starting to take Difenatil.
During treatment with Difenatil, inform your doctor immediately:
If the pain persists for more than 5 days, the fever for more than 3 days, or if the pain or fever worsen or other symptoms appear, the clinical situation should be evaluated by your doctor. This medicine should not be used for self-medication of high fever (over 39°C), fever that lasts more than 3 days, or recurrent fever, unless indicated by your doctor, as these situations may require medical evaluation and treatment.
If you have severe diseases, such as severe kidney failure or sepsis (when bacteria and their toxins circulate in the blood, causing damage to organs), 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 respiratory distress with deep and rapid breathing, drowsiness, feeling of discomfort (nausea) and vomiting.
Administration of paracetamol doses higher than recommended implies a very serious risk of liver injury. Medicines that contain 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 medicine.
Children and adolescents
This medicine should not be used in children under 15 years or weighing less than 50 kg.

High daily doses of paracetamol should be avoided during prolonged periods of time, as the risk of adverse effects such as liver damage increases.
The administration of this medicine 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 if the pain or fever worsen or other symptoms appear, you should interrupt treatment and consult your doctor.

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