Search for "Micromedex" and several apps will come up. Choose the one you need (for example, "Micromedex Drug Interactions") and install it.
Open up the Micromedex website through the All Databases List or at the link below.
Once you have Micromedex open, click on Mobile Application Access in the upper right corner. Expand the first section on that page, called Mircomedex Native Mobile Apps.
Scroll down to the access information for the app you downloaded and locate the app password (look for Step 4).
In the app, hit the blue Continue button at the bottom of your screen. Agree to the terms and conditions, and enter the password from the step above to access the app. Heads up: The password is case sensitive.
