Thanks to everyone who posted links to free programs. I loaded
Mobile MerckMedicus onto my smartphone & absolutely LOVE it. I had already purchased Davis's Drug Guide for my phone and use it all the time. It's so convenient to have the information at my fingertips -- much easier than searching for a book or an open computer.
Registering on the Merck website also gave me free access to pt education sheets -- a bonus for me because I work part-time in the community & can always use handouts.
