Background/Aims: Many senior adult patients often face the use of multiple medications with challenges in adhering to the agreed upon regimens. This study focused on addressing health literacy, an underlying medication non-adherence factor. A smartphone application to deliver medication regimen instructions in an easy-to-understand format was developed and tested for its usability by seniors. Methods: Niaspan 500 mg, a drug with a relatively complex regimen, was presented to seniors with minimal text information, images, and verbal instructions from a Palm Pre 2Â® smartphone.
