What drug reference do you use?

Just curious as to what drug reference do you use and why you like it?
I use the Hospital Drug Formulary icon on my work computer. Unlike a book, the lists add new drugs and are kept up to date.I still have my 1998 Lipincott manual I bought when I started working, it is kept for sentimental reasons.

I am partial to paper drug books and usually picked up a Mosby Drug Reference each year for my unit.

Lexi-comp on iPhone and Micromedix on iPad.

This has been pretty helpful. They organize all the drugs into concise charts:Pharm Charts

I also like Lexicomp on my iphone.

Epocrates on my smartphone.

I still love my Skyscape

I have not re-upped my Skyscape for several years. I just use what's there. It's good for admin detail because it's of a nursing sort of understanding. Other than that I have Micromedex and Medscape and Epocrates (which, I almost never use).

M'eh, the $90 year for Skyscape is a bit, but I am so used to it, it has so much in the nursing constellation..

I use Up To Date when I'm on the computer, and I think we have a Davis in the med room.

I personally use the Davis Drug Guide for Nurses. Why? Simple... it's a school required reference. At least I can also get an online subscription for free if I get the book. I can access their drug guide on my smartphone, but we're not allowed to use the phone while on the floor so... I will also use Lexicomp, which the hospital uses. I have to wade through a lot of info when I use that, but it's a great reference! I'd use it at home if I could...

Clinical Pharmacology. It's free and very easy to use. It's the hospital-approved reference. I also have epocrates on my phone and use that from time to time.
