– chronic viral hepatitis and HIV, cystic fibrosis, Gilbert’s disease.

Consumption of alcoholic beverages during treatment is not recommended.
In case of recent withdrawal from chronic alcoholism, the risk of liver damage is increased.
If acute viral hepatitis is discovered, treatment should be stopped.

Rare cases of sometimes severe allergic reaction have been reported. In this case paracetamol is to be avoided.
Reactions such as erythema, skin rash, urticaria are possible but exceptional. Treatment should be stopped and avoided.
Mild to severe liver damage is possible.

Symptoms :

Nausea, vomiting, anorexia, pallor, abdominal pain usually appear within the first 24 hours.

Paracetamol overdose may cause hepatic cytolysis which may lead to hepatocellular insufficiency, metabolic acidosis, encephalopathy, coma and death.

In the event of an acute overdose, an increase in hepatic transaminases, lactate dehydrogenase, bilirubin and a decrease in prothrombin level can be observed within 12 to 48 hours.

Overdose can also lead to pancreatitis, hyperamylasemia and acute renal failure.

Emergency driving:

Immediate transfer to hospital.

Collect a tube of blood for the initial plasma paracetamol assay. This dosage will be interpreted according to the delay between the supposed time of intake and the time of sampling.

Rapid evacuation of the ingested product by gastric lavage, in the event of oral intake.

The treatment of overdose typically includes the administration, as early as possible, of the antidote N-acetylcysteine by IV or oral route, if possible before the tenth hour.
