Citing Databases in AMA

Drug Information and Medical Resources General Information


General Database Format 

Author/page title Database Publisher Date/last update Accessed URL
Author AA. Database Title. Publisher Name; 2021. Accessed Month day, Year www.xx.xx
Page name Database title [database online]. Publisher Name; Updated April 30, 2021 Accessed Month day, year www.xx.xx


General Notes:

  • When a database has a common name, include “[database online]” after its title to help the reader understand what you are citing. AMA uses square brackets for explanatory notes.
  • When listing URLs, provide the database’s primary URL (listed below for each database). Do not use the long URL that you see when accessing the database.
  • Some databases do not list authors. If no author is listed, start your citation with the name of the drug or page you are citing.
  • As of the 11th edition, AMA no longer recommends a location of the publisher in a citation

Database Specific Notes

  • Use the drug name (or page title) for the information you are citing.
  • Indicate the section or book that you are citing (e.g., Quick Answers, In-Depth Answers, Martindale: The Complete Drug Reference, and RED BOOK Online in the above examples).
  • Make sure to cite the latest publication or copyright date (2020 in the above examples). Look at the bottom of the monograph or page for a publication/update date; if none is listed go to the very bottom of the page and use the Micromedex copyright date listed.
  • Change the access date to the date you read the information.


9. Solomon DH. Nonselective NSAIDs: Adverse Cardiovascular Effects. UpToDate. UpToDate; 2020. Accessed June 11, 2020.

Database Specific Notes

  • Use the “topic” that you are citing as the title.
  • UpToDate is both the database and the publisher name, which is why it’s listed twice.
  • Since UpToDate is updated every four months, use the current year as the publication date (2020 in the above example).
  • UpToDate recommends using a different method of citing its topics, but the above method is consistent with the AMA Manual of Style, 11th ed., approach to citing databases.
