Trick-of-the-Trade: IV Compatibility Information at Your Fingertips

Bryan D. Hayes, PharmD, DABAT, FAACT, FASHP |

MicromedexWe often have less than optimal IV access to administer fluids, blood products, and medications in sick ED patients. If more than one medication needs to be infused in the same line, how do we know if they are compatible? The gold standard for checking IV compatibility is Trissel’s Stability of Compounded Formulations. 1 But a textbook doesn’t help us in critical situations. Is there a better way?


Use the free Micromedex IV Compatibility app

Many institutions and schools subscribe to Micromedex products, which translates into free access for you.

Step 1

Download the free Micromedex IV Compatibility app from iTunes or Google Play. Micromedex also has free drug information and drug interaction apps.

Step 2

Navigate to the Micromedex page from your hospital or school library.

Step 3

Click on ‘Download Mobile Apps.’

Step 4

Scroll down to the information for the IV Compatibility app. The password will be available for you to enter into the app. This password changes every 3 months (usually you realize it when you’re in the middle of a resuscitation), so make sure to check back and update it periodically.
