Objective: To evaluate tertiary drug information databases in terms of scope, consistency of content, and completeness of COVID-19 drug information.

Methods: Five electronic drug information databases: Clinical Pharmacology, Lexi-Drugs, AHFS DI (American Hospital Formulary Service Drug Information), eFacts and Comparisons, and Micromedex In-Depth Answers, were evaluated in this cross-sectional evaluation study, with data gathered from October 2021 through February 2022. Two study investigators independently extracted data (parallel extraction) from each resource.
