Pillboxr is a Ruby wrapper for the National Library of Medicine Pillbox API Service located at http://pillbox.nlm.nih.gov](http://pillbox.nlm.nih.gov). The pillbox API provides information from the FDA about various prescription medications. The current version of this library has two forms. The first (preferred) version does not depend on any gems except for `httparty`. The second version depends upon `active_resource`. This version of Pillboxr inherits from ActiveResource to perform its XML wrapping so ActiveResource 3.2.6 is a requirement for using the wrapper. This deprecated version is not included in the distributed gem but the library code can be found at [https://github.com/kgautreaux/pillboxr](https://github.com/kgautreaux/pillboxr). *Note:* This library is designed for use with Ruby 1.9.3 and above, and will not work with earlier versions of Ruby.
