This products yields very useful info - but I experience multiple difficulties using the mobile app. Every time it upgrades (quarterly at least, when. They provide new data), I need to re-enter a new password. As I have a subscription to this through my hospital, I need to be at a workstation in the hospital network to find. The new password for this quarter. In other words, I cannot use this mobile app without first sitting down at a workstation. Even worse, sometimes the password does not even work. I just updated and entered the password from our library, and its not accepted. Our librarians contacted Thompson-Reuters (Micromedex) tech support. They shared "they are aware of the problem, but they dont have access to the new password. No time estimate on when the web page will be updated with the new password. Their advice is to use the web interface until this problem is corrected." My advice is if youre going to spend money for a mobile drug interaction program, do it with a company that understands and is committed to supporting a mobile platform. Based on my experience, Micromedex (Thompson Reuters) does not fit my needs.
