 Abstract 
 Objective – To compare the content veracity and comprehensiveness of Lexicomp and Wikipedia with respect to drug information.
 Design – Comparative study.
 Subjects – Lexicomp and Wikipedia.
 Methods – Five of the six most commonly prescribed medications in Canada were selected for content comparison in both Lexicomp and Wikipedia (levothyroxine, atorvastatin, pantoprazole, acetylsalicylic acid, and metformin). Three categories compared included dose and instructions, uses, and adverse effects or warnings; sixteen subcategories were identified to provide further comparative detail. Five outcomes were assessed using a rating scale to identify the presence or absence of each subcategory for each drug entry: present in neither source, present in Wikipedia but not Lexicomp, present in Lexicomp but not in Wikipedia, present in both without discrepancies, and present in both with discrepancies. The only subcategory meeting the criteria for “present in both with discrepancies” for all five medications was adverse reactions, indicating that the information in each resource differed. A “fact-checking literature search” in MEDLINE and EMBASE as well as searches in the USFDA Prescribing Information (supplemental index) (FDA PIs) and the FDA Adverse Events Reporting Systems (FDAERS) were used to determine the veracity of the discrepancies. Quantitative assessment was used to determine how comprehensive the entries were in terms of the number of times in which each resource provided subcategory information. Adverse reaction information was expressed as a percentage based on the number of adverse reactions identified in the sources.
 Main Results – Overall, Lexicomp was shown to provide more comprehensive information than Wikipedia. In the subheading analysis, there was no instance in which Wikipedia contained information while Lexicomp did not, while in over half of instances Lexicomp only contained the information. 18% of subheading information was found in both with discrepancies and 20% was found in both without discrepancies. Only 10% of instances were not present in Lexicomp or Wikipedia. Detailed dosing information was consistently present in Lexicomp for all five medications while only general dosage information was present in just two instances in Wikipedia.
 Of all the subcategory comparisons, adverse reactions was the only one identified as “present with discrepancies” for all medications being compared; MEDLINE, EMBASE, FDA PIs and the FAERS dashboard searches were performed for a total of 309 discrepant adverse reactions. 63% (191/302) of the adverse reactions listed in Lexicomp were supported by the literature retrieved from MEDLINE and EMBASE compared to 100% (7/7) of those listed in Wikipedia. Of the Lexicomp adverse reactions unsupported by the peer-reviewed literature, 17% were supported from information found in FDA PIs and 90% supported from information found in the FAERS dashboard. A “substantial proportion” of adverse events listed in Lexicomp were not supported in any retrieved literature.
 Conclusion – Based on the comparative criteria, drug information in Lexicomp for the five medications was found to be more comprehensive than Wikipedia. Adverse effects listed in Lexicomp did not always have corresponding support in the published peer-reviewed literature.
