AHFS is a great source of in-depth information regarding medications. It is referenced & easy to locate needed information. In retail I used Facts & Comparisons, but AHFS is more useful for my current job.

It is a great reference and has just about everything that you need to know. It is great for dosing guidelines. You can also find things that you can't find readily everywhere else, like some compounding information.
