Resources for Mobile Users

WebMD Mobile Apps

WebMD offers a range of free health-related apps. The general WebMD Mobile App contains medication information and is available for iOS and Android devices. The Medscape Mobile App is clinician-oriented and is available for iOS, Android, and Kindle Fire devices.



Epocrates Rx is a free, clinician-oriented mobile app specifically for medication information. It is available for iOS and Android devices. However, as this New York Times article details, it is heavily laden with paid pharmaceutical advertising.


Regulation of Mobile Medical Apps

As with any medical information source, practice caution when consuming information from mobile medical apps and do not act on any information without the advice of a physician. The FDA's page on Mobile Medical Applications provides specific information on how mobile medical apps are (and are not) subject to regulation.



These sites are versions of resources listed elsewhere in this guide, optimized for display on mobile devices.

Both resources are provided by the U.S. National Library of Medicine.
