From the digestive system: nausea, epigastric pain, increased activity of liver enzymes, hepatonecrosis. From the endocrine system: hypoglycemia. If unusual symptoms occur, consult a doctor.

Drug Interaction

When used in conjunction with inducers of microsomal liver enzymes, agents with hepatotoxic activity, there is a risk of increased hepatotoxic action of paracetamol.

When administered with anticoagulants, a slight or moderate increase in prothrombin time is possible.

In combination with anticholinergic agents, paracetamol absorption may be reduced.

With simultaneous use with oral contraceptives, the excretion of paracetamol from the body is accelerated and its analgesic action may be reduced.

When used with uricosuric agents, their effectiveness decreases.

Simultaneous use of activated carbon reduces the bioavailability of paracetamol.

Diazepam excretion may be decreased when co-administered with diazepam.

There are reports of the possibility of enhancing the myelodepressive effect of zidovudine when co-administered with paracetamol. A case of severe toxic liver damage is described.

Cases of toxic effects of paracetamol when co-administered with isoniazid have been described.

When used with carbamazepine, phenytoin, phenobarbital, primidone reduces the effectiveness of paracetamol, which is due to an increase in its metabolism (processes of glucuronidation and oxidation) and excretion. Cases of hepatotoxicity with the simultaneous use of paracetamol and phenobarbital have been described.

When using cholestyramine for less than 1 h after the administration of paracetamol, the absorption of the latter may be reduced.

With simultaneous use with lamotrigine, the excretion of lamotrigine is moderately increased from the body.

When used with metoclopramide, it is possible to increase the absorption of paracetamol and increase its concentration in blood plasma.

When co-administered with probenecid, paracetamol clearance may be reduced with rifampicin, sulfinpyrazone may increase paracetamol clearance due to increased hepatic metabolism.

When co-administered with ethinyl estradiol, the absorption of paracetamol from the intestine increases.

Overdose

Signs of an overdose of paracetamol - nausea, vomiting, stomach pain, paleness of the skin, anorexia. After a day or two, signs of liver damage are determined. In severe cases, liver failure and coma develops. A specific antidote for paracetamol poisoning is N-acetylcysteine.

Symptoms: pallor of the skin, anorexia, nausea, vomiting, hepatonecrosis (the severity of necrosis directly depends on the degree of overdose). If overdose is suspected, seek medical attention immediately. The toxic effect of the drug in adults is possible after taking more than 10-15 g of paracetamol: increased activity of hepatic transaminases, an increase in prothrombin time (12-48 h after administration) a detailed clinical picture of liver damage manifests itself in 1-6 days. Rarely, impaired liver function develops rapidly and may be complicated by renal failure (tubular necrosis).

Treatment: the patient should do gastric lavage during the first 4 hours of poisoning, take adsorbents (activated charcoal) and see a doctor, the introduction of donors of SH-groups and precursors of synthesis of glutathione - methionine in 8-9 h after overdose and N-acetylcysteine ​​- after 12 h. The need for additional therapeutic measures (further administration of methionine, in / in the introduction of N-acetylcysteine) is determined depending on the concentration of paracetamol in the blood, as well as the time elapsed after its administration.
