1. What is Difenatil and what is it used for
Paracetamol is effective for reducing pain and fever.
It is indicated for the symptomatic relief of occasional mild to moderate pain and in febrile states in adults and adolescents over 15 years (body weight over 50 kg).
2. What you need to know before you take Difenatil

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.
- Do not take more medicine than recommended in section 3. How to take Difenatil.
- If you have liver problems, including liver problems due to excessive alcohol consumption (3 or more alcoholic drinks per day).
- 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 medicine to treat epilepsy, you should consult your doctor before taking this medicine, 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 Other medicines and Difenatil).
- If you have Gilbert's disease (also known as Meulengracht's disease).
- If you have heart failure, respiratory failure, or anemia; 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 medicine 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 grams per day.
- The simultaneous use of this medicine with other medicines that contain paracetamol should be avoided; for example, medicines for flu and colds, as high doses can lead to liver damage. Do not use more than one medicine that contains paracetamol without consulting your doctor.
- If an overdose occurs, seek medical attention immediately (see "If you take more Difenatil than you should").
- Chronic alcoholics should be cautious not to take more than 2 grams of paracetamol in 24 hours.
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.
Other medicines and Difenatil

In particular, if you are using any of the following medicines, it may be necessary to modify the dose of some of them or interrupt treatment:
- Medicines to prevent blood clots: Oral anticoagulants (acenocoumarol, warfarin).

Inform your doctor or pharmacist if you are taking:
- Flucloxacillin (antibiotic), due to a serious risk of blood and fluid anomaly (called metabolic acidosis) that requires urgent treatment (see section 2).
Interference with laboratory tests:
If you are going to have any laboratory tests (including blood tests, urine tests, etc.), inform your doctor that you are taking this medicine, as it may alter the results. Paracetamol may alter the values of analytical determinations of uric acid and glucose.
Taking Difenatil with food, drinks, and alcohol
The use of paracetamol in patients who habitually consume alcohol (3 or more alcoholic drinks: beer, wine, liquor, ... per day) may cause liver damage.
Taking this medicine with food does not affect its efficacy.
Pregnancy, breastfeeding, and fertility
Consult your doctor or pharmacist before using any medicine.
Pregnancy
If necessary, Difenatil can be used during pregnancy. You should use the lowest possible dose that reduces pain or fever and use it for the shortest possible time. Contact your doctor if the pain or fever does not decrease or if you need to take the medicine more frequently.
Breastfeeding
Consult your doctor or pharmacist before taking this medicine.
Paracetamol passes into breast milk, so breastfeeding women should consult their doctor or pharmacist before taking this medicine.

The symptoms of overdose may be: dizziness, vomiting, loss of appetite, yellowing of the skin and eyes (jaundice), abdominal pain, and pancreatitis (inflammation of the pancreas).
Treatment of overdose is more effective if started within 4 hours after ingestion of the medicine.
Patients treated with barbiturates or chronic alcoholics may be more susceptible to the toxicity of a paracetamol overdose.
