If you are open to an app, Epocrates and Nursing Central are my recommendations.
They cost money, I think $180?
If you want a booklet, Tarascon is great. I have an older edition, but a new one will only run you ~15. My husband is a PA and has found that this gives him a great summary of what you "need" to know.
I personally use epocrates, or the drug info in the MAR. Chances are, your system you use in the hospital will have a drug information sheet available (usually via a right click over the drug) in the MAR. You could always wait and see if it suits your needs.
