Nonsteroidal anti-inflammatory drugs, non-narcotic analgesics and drugs that depress the central nervous system can increase the side effect of the drug.
The risk of developing a hepatotoxic effect increases with the simultaneous administration of barbiturates, phenytoin, carbamazepine, rifampicin, zidovudine, phenylbutazone, tricyclic antidepressants and other inducers of microsomal liver enzymes, while consuming alcohol. With simultaneous use with levomitsetinom (chloramphenicol) excretion of the latter slows down and toxicity increases. Speed suction of paracetamol increases with metoclopramide or domperidone, the slowing of absorption occurs when combined with colestyramine.
Long-term use of barbiturates reduces the effectiveness of paracetamol.
Ethanol promotes the development of acute pancreatitis.
Inhibitors of microsomal oxidation (incl. cimetidine) reduce the risk of hepatotoxic effects.
Diflunisal increases the plasma concentration of paracetamol by 50% - the risk of developing hepatotoxicity.
Myelotoxic drugs increase the manifestation of hematotoxicity of the drug. Long-term use Flukoldeks syrup withanticoagulants of indirect action should be under constant medical supervision, tk. increases the effect of the latter.
Inductors of microsomal oxidation in the liver (phenytoite, ethanol, barbiturates, rifampicin, phenylbutazone, triktsiklicheskie antidepressants), ethanol and hepatotoxic drugs increase the production of hydroxylated active metabolites, which makes it possible to develop severe intoxication even with a slight overdose.
Paracetamol reduces the effectiveness of uricosuric drugs and increases the effect of indirect anticoagulants.
