Administration of Paracetamol in Infants

Route Selection Guidelines

The route of paracetamol administration in infants should be based on clinical setting, with oral administration preferred whenever possible and intravenous administration reserved for postoperative settings or when oral route is not feasible, as recommended by the American Society of Anesthesiologists 1, 2
Aim for oral administration as soon as possible in postoperative settings to minimize invasive interventions, according to the American Academy of Pediatrics 1, 3
IV paracetamol is indicated in postoperative settings, particularly in the PACU and during the immediate postoperative period, as suggested by the Society of Pediatric Anesthesia 1, 4
IV paracetamol should be used when the oral route is not feasible due to NPO status, inability to tolerate oral medications, or need for rapid onset of analgesia, as recommended by the American College of Clinical Pharmacy 4, 5, 6, 7, 8

For basic level postoperative care, use rectal paracetamol in combination with local anesthetics, as recommended by the European Society of Paediatric Anaesthesiology 1, 2
For intermediate level care, use rectal or IV paracetamol, transitioning to oral as soon as possible, according to the American Society of Regional Anesthesia and Pain Medicine 4, 3
Combine paracetamol with NSAIDs when possible to reduce opioid requirements, as suggested by the World Health Organization 1, 3

Ensure adequate monitoring when using IV paracetamol in infants, particularly in postoperative settings, as recommended by the American Academy of Pediatrics 1, 2
For infants undergoing procedures like circumcision, consider paracetamol as part of a multimodal approach rather than as sole therapy, according to the American Academy of Pediatrics 9
