Intentional pediatric nonprescription cold/cough and analgesic/antipyretic exposure trends amid the COVID-19 pandemic.

INTRODUCTION

The objective of this study is to examine US Poison Center intentional pediatric nonprescription analgesics/antipyretic and cold/cough exposure trends involving abuse/misuse and suspected suicide amid the COVID-19 pandemic.

METHODS

Using descriptive and interrupted time-series analyses, we assessed monthly pediatric (6-17 years) exposure case rates involving nonprescription analgesic/antipyretic drugs containing paracetamol (acetaminophen), ibuprofen, acetylsalicylic acid, and naproxen, and cold/cough drugs containing dextromethorphan, guaifenesin, pseudoephedrine, and phenylephrine, before (1/1/2015-2/29/2020) and during (4/1/2020-4/30/2023) the COVID-19 pandemic. Statins served as a control.

RESULTS

Nearly half of pediatric intentional cough/cold (40-56%) and analgesic/antipyretic (51-62%) cases involved a single substance, unlike the control (22%). Most cases entailed intentional-suspected suicide exposures (cold/cough 55-78%; analgesic/antipyretic 89-92%; control 96%) followed by intentional-abuse/misuse (cold/cough 17-40%; analgesic/antipyretic 6-8%; control 3%). Cases commonly involved adolescents, 13-17 years (cold/cough 88-93%; analgesic/antipyretic 90-92%; control 88%) and females (cold/cough 56-71%; analgesic/antipyretic 84-85%; control 82%). Paracetamol intentional-abuse/misuse and dextromethorphan suspected suicide case rates declined immediately following the pandemic's onset (March 2020), among adolescents. Case rates for guaifenesin, paracetamol, and ibuprofen intentional-suspected suicides exceeded pre-pandemic levels and exhibited statistically significant increased trend changes for adolescents (0.016, 0.246, and 0.116 cases per million population per month, respectively); and for guaifenesin for female (0.03 cases per million population). Male and female intentional-abuse/misuse case rates trends for some study drugs also increased; primarily for adolescents.

CONCLUSION

Some analgesic/antipyretic and cold/cough intentional-suspected suicide case rates notably increased during the pandemic for adolescents, particularly females. This surge aligns with periods of increased psychological stress, suicidal ideation/attempts, and certain nonprescription drug exposures potentially attributed to the COVID-19 pandemic.
