## TL;DR

California's poison control system saw ivermectin exposures rise steadily through 2021 as people tried it against COVID-19, from about 14 a month to a rising monthly count.

## Summary

Interrupted time-series analysis of California Poison Control System reports from 2015 through 2021 found that reported ivermectin exposures were stable at 14.5 a month before December 2020 and then increased by 2.05 a month through December 2021 (Ghai poison centre trends 2024). Exposures to household cleaning products also rose sharply in March 2020, while antimalarial exposures did not change significantly (Ghai poison centre trends 2024).

- Findings: Ivermectin exposure reports rose by about two a month from December 2020 through December 2021, from a baseline of 14.5 a month.
- What it means: Population-level evidence that when a drug is promoted online for an unproven use, poison centres see the result.
- Caveats: Reports to a poison centre undercount exposures and do not record severity in this analysis.
