Adverse reaction

The most common adverse reactions in patients treated with acetaminophen were nausea, vomiting, headache, and insomnia in adult patients and nausea,vomiting, constipation, pruritus, agitation, and atelectasis in pediatric patients.

Drug interactions

Substances that induce or regulate hepatic cytochrome enzyme CYP2E1 may alter the metabolism of acetaminophen and increase its hepatotoxic potential. Chronic oral acetaminophen use at a dose of 4,000 mg/day has been shown to cause an increase in international normalized ratio (INR) in some patients who have been stabilized on sodium warfarin as an anticoagulant.
