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.
