Drug interactions
Concomitant treatment with aminophenazone may lead to an increase of the effects
of both medicines. Paracetamol potentiates effects of the anticoagulant medicines.
Phenobarbital increases the harming effect of Paracetamol on the liver. Contraceptive
preparations and rifampicin reduce the effectivity of Paracetamol. Cimetidin reduces
toxicity and potentiates the analgesic effect of the preparation. Paracetamol potentiates
the action of the Chloramphenicol. Concomitant usage of alcohol and medicines harming
the liver, enhances the risk of severe liver disorders.
Adverse reactions
In rare cases hypersensitivity reactions, predominantly skin allergy (itching
and rash), may appear. Long-term treatment with high doses may cause a toxic hepatitis
with following initial symptoms: nausea, vomiting, sweating, and discomfort. Occasionally
a gastrointestinal discomfort may be seen.
Pharmacological mechanisms
Paracetamol possesses prominent antipyretic and analgesic effects. Its anti-inflammatory
activity is weak and has no clinical significance. The mechanism of action is related
to depression of the prostaglandin synthesis by inhibition of the specific cell
cyclooxygenase, and depression of the thermoregulatory center in the medulla oblongata.
