Antipyretic Effectiveness of Oral Acetaminophen Versus Rectal Acetaminophen in Pediatric Patients With Fever
Abstract
BACKGROUND AND OBJECTIVE: Acetaminophen, one of the routine medicines used for temperature reduction in febrile children, is available in multiple routes of administration, including oral and rectal routes. Our objective is to compare the antipyretic effectiveness of oral acetaminophen versus rectal acetaminophen in pediatric patients with fever in terms of temperature reduction.
METHODS: Medline and Embase databases were searched from inception to August 2021. Cohort studies, case-control studies, experimental studies, and randomized controlled trial studies comparing oral and rectal administered acetaminophen in pediatric patients were included. Two reviewers independently extracted data.
RESULTS: A total of 5 randomized studies (n = 362) were included in the meta-analysis. No significant difference was found between oral and rectal acetaminophen in temperature reduction at 1 hour (weighted mean difference [WMD], 0.04°C; 95% confidence interval [CI], -0.10°C to 0.19°C; P = .501) or 3 hours (WMD, -0.14°C; 95% CI, -0.37°C to 0.10°C; P = .212) after administration (WMD, -0.14°C; 95% CI, -0.37°C to 0.10°C; P = .212).
CONCLUSION: Oral and rectal acetaminophen have no significant difference in antipyretic effectiveness at 1 and 3 hours after administration. If both options are available, oral acetaminophen would be preferred because of a more predictable drug level after administration. However, for febrile children with specific circumstances for whom oral acetaminophen could…
