★★★★★ This app does not work unless you pay for it.
★★★★★ My app won't allow me to log on since getting my new phone. I do have an older version but it worked great for me. When I try to log on it tells me I purchased from the App Store and need to “restore” from there. There…

★★★★★ The app is stuck on a loading screen and will not advance.
★★★★★ I have relied on this drug guide frequently as a reference. I am a flight paramedic and this app has been helpful because it does not require the internet to function. There have been 3 recent occasions that I needed…
★★★★★ I was able to continue to use the content I purchased until my device (iPhone 6) recently crashed, which required going back to default settings.

★★★★★ Davis drug guide is fast and easy to use.
★★★★★ Its fast and has medication pronunciation for medications that aren't as common.

Everything at my fingertips. So easy to use and has so much content. Highly recommended!
I bought the book and I had the code to download the app on my phone. I think it’s really unfair how I have to pay more money to get full access of the list of medications!
I remember when these guides were in a ginormous textbook. This guide is convenient and has colorful pix. The best part is the Pronunciation Guide! With the glut of medications, it great to hear the precise pronunciation. The Calculator section is very handy too.
I have Davis’s Drug Guide for years, student, Paramedic and Hospital as well as family. The updates are good!
Good resource. However not enough depth on pharmacology
This is a must have clinical guide. Easy to use and very navigable. Explicit and concise way of understanding pharmacology.
