Hypersensitivity to paracetamol or propacetamol hydrochloride (precursor of paracetamol) or to any of the excipients listed in section 6.1.

Side effects

Skin reactions of various types and severities have been reported with the use of paracetamol including cases of erythema multiforme, Stevens-Johnson syndrome and epidermal necrolysis. Hypersensitivity reactions such as angioedema, larynx edema, anaphylactic shock have been reported. In addition, the following undesirable effects have been reported: thrombocytopenia, leukopenia, anemia, agranulocytosis, liver function abnormalities and hepatitis, kidney disorders (acute renal failure, interstitial nephritis, haematuria, anuria), gastrointestinal reactions and dizziness. The table below lists the adverse reactions, some of which have already been mentioned above, associated with the administration of paracetamol, resulting from post-marketing surveillance. Adverse reactions are listed by System Organ Class, using MedDRA terminology (inserting PT). The frequency of adverse reactions listed below is not known.

Disorders of the blood and lymphatic system Thrombocytopenia, Neutropenia, Leukopenia.
Gastrointestinal disorders Diarrhea, Abdominal pain.
Hepatobiliary disorders Hepatic enzyme increased.
Disorders of the immune system Anaphylactic shock, Angioedema, Hypersensitivity.
Diagnostic tests International normalized ratio decreased, International normalized ratio increased.
Skin and subcutaneous tissue disorders Urticaria, Erythema, Rash.
Vascular pathologies Hypotension*.

* As a symptom of anaphylaxis. In case of overdose, paracetamol can cause hepatic cytolysis which can evolve towards massive and irreversible necrosis (see also section 4.9).Reporting of suspected adverse reactionsReporting of suspected adverse reactions that occur after authorization of the medicine is important, as it allows continuous monitoring of the benefit / risk ratio of the medicine. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system at “https://www.aifa.gov.it/content/segnalazioni-reazioni-avverse”.

Special warnings

Paracetamol should be administered with caution to patients with mild to moderate hepatic insufficiency (including Gilbert's syndrome), severe hepatic insufficiency (Child-Pugh> 9), acute hepatitis, concomitant treatment with drugs that impair liver function, deficiency of glucose-6-phosphate-dehydrogenase, haemolytic anemia. Do not administer during chronic treatment with drugs that can determine the induction of hepatic monooxygenases or in case of exposure to substances that can have this effect (see section 4.5). Paracetamol should be administered with caution in subjects with renal insufficiency (creatinine clearance ≤ 30 ml / min). Use with caution in case of chronic alcoholism, excessive alcohol intake (3 or more alcoholic drinks per day), anorexia, bulimia or cachexia, chronic malnutrition (low reserves of hepatic glutathione), dehydration, hypovolemia. During treatment with paracetamol, before taking any other drug, check that it does not contain the same active ingredient, as if paracetamol is taken in high doses, serious adverse reactions can occur. Instruct the patient to contact the physician before combining any other drugs (see also section 4.5). High or prolonged doses of the product can cause high-risk liver disease and alterations, even serious ones, in the kidney and blood. In case of prolonged use it is advisable to monitor liver and kidney function and blood count. In case of allergic reactions the administration should be suspended.Important warnings about some excipientsOne tablet contains: • 412.3 mg of sodium, equivalent to approximately 20% of the WHO recommended maximum daily intake, which corresponds to 2 g of sodium for an adult. This medicine is therefore considered to be high in sodium. To be taken into consideration in patients on a low sodium diet; • 300 mg of sorbitol (E420): patients with hereditary fructose intolerance should not be given this medicine; • 60.606 mg of sodium benzoate (E211).

Pregnancy and breastfeeding

Clinical experience with the use of paracetamol during pregnancy and lactation is limited.PregnancyEpidemiological data on the use of therapeutic doses of oral paracetamol indicate that no undesirable effects occur in pregnant women or on the health of the fetus or neonates. Reproductive studies with paracetamol did not reveal any malformation or foetotoxic effects. Epidemiological studies of neurodevelopmental in children exposed to paracetamol in utero show inconclusive results. However, paracetamol should only be used during pregnancy after careful consideration of the risk / benefit ratio. If clinically necessary, in pregnant patients, the recommended posology and duration of treatment should be strictly observed.Feeding timeParacetamol is excreted in small quantities in breast milk. Rash has been reported in breast-fed infants. However, administration of paracetamol is considered compatible with breastfeeding. However, caution should be exercised in administering paracetamol to breastfeeding women.

Expiration and retention

This medicine does not require any special storage conditions.

Interactions with other drugs

Paracetamol can increase the chance of side effects if given at the same time as other drugs. The administration of paracetamol can interfere with the determination of uricaemia (by the phosphotungstic acid method) and with that of blood glucose (by the glucose-oxidase-peroxidase method). During therapy with oral anticoagulants it is recommended to reduce the doses.Monooxygenase inducing drugsUse with extreme caution and under strict control during chronic treatment with drugs that can determine the induction of hepatic monooxygenases or in case of exposure to substances that can have this effect (for example rifampicin, cimetidine, antiepileptics such as glutethimide, phenobarbital, carbamazepine) .PhenytoinConcomitant administration of phenytoin may result in decreased efficacy of paracetamol and an increased risk of hepatotoxicity. Patients being treated with phenytoin should avoid taking high and / or chronic doses of paracetamol. Patients should be monitored for evidence of hepatotoxicity.ProbenecidProbenecid causes an at least two-fold reduction in paracetamol clearance through inhibition of its conjugation with glucuronic acid. A dose reduction of paracetamol should be considered when administered concomitantly with probenecid.SalicylamideSalicylamide can prolong the elimination half-life (t1/2) of paracetamol.


There is a risk of intoxication, especially in patients with liver disease, in cases of chronic alcoholism, in patients with chronic malnutrition, and in patients receiving enzyme inducers. In these cases, overdose can be fatal. Symptoms generally appear within the first 24 hours and include: nausea, vomiting, anorexia, paleness, malaise and diaphoresis. Overdose with acute ingestion of 7.5 g or more of paracetamol in adults and 140 mg / kg body weight in children causes hepatic cytolysis which can progress to complete and irreversible necrosis, resulting in hepatocellular failure, metabolic acidosis and encephalopathy, which can lead to coma and death. At the same time, increased levels of hepatic transaminases (AST, ALT), lactic dehydrogenase and bilirubin are observed, together with a decrease in the prothrombin value, which may occur 12 to 48 hours after administration. Clinical symptoms of liver damage usually manifest themselves after one or two days, and reach their maximum after 3 - 4 days.Emergency measures• Immediate hospitalization; • Before starting treatment, take a blood sample to determine plasma paracetamol levels as soon as possible, but not earlier than 4 hours after the overdose; • Rapid elimination of paracetamol by gastric lavage; • Treatment following an overdose includes administration of the antidote, N-acetylcysteine (NAC), intravenously or orally, if possible, within 8 hours of ingestion. The NAC can, however, give a certain degree of protection even after 16 hours; • Symptomatic treatment. Liver tests should be performed at the start of treatment and will be repeated every 24 hours. In most cases, liver transaminases return to normal within a week or two with full recovery of liver function. In very severe cases, however, liver transplantation may be necessary.
