Modified from Zeltzer LK and others: Report of the subcommittee on the management of pain associated with procedures in children with cancer. Pediatrics 86 (suppl): 826-831, 1990; and Coté CJ: Sedation for the pediatric patient, Pediatr Clin North Am 41 (1): 31-58, 1994.

* Provide analgesia and sedation.

Not recommended for children less than 15 kg. Lozenges should be sucked, not chewed and swallowed. If chewed, drug is less effective because part of it is metabolized by liver before entering bloodstream. Swallowing drug rapidly does not increase risk of respiratory depression during first 15 to 30 minutes, period of greatest risk for decreased respiration.

Provide sedation but no analgesia.
