I ordered my formuarly online, from Amazon.com, a couple of years ago. They should really be purchased every year or so because the information does change. I primarily bought it for drug dosage information for drugs not normally given to rats like Diazepam (Valium) and information on OTC drugs like aspirin. It has heart meds listed, it covers LRS amounts, gas levels for anethesia, probiotic information, the works!
For the rodents, the sections are broken down into:
Antimicrobial and antifungal agents - Baytril etc.
Antiparasitic agents - Ivermectin, Selemectin etc.
Chemical restraint/anesthetic agents - Diazepam, Isoflurane etc.
Analgesics - Acetaminophen (Tylenol Syrup), Ibuprofen, Metacam etc.
Emergency drugs - Dexamethasone, Furosemide (Lasix) etc.
Miscellaneous agents - Aminophylline, Digoxin, Lactobacilli (probiotic), vitamins and minerals, etc.
Each section for each drugs has a 'comment' section that would include things like dangers and sometimes the side affects.
Plus, it contains all their physical information, weight, temperature, heart rate, breath rate, age.
It is awesome.
It is the following:
Third Edition - 2005
James W. Carpenter
Exotic Animal Formulary
0-7216-0180-4
It doesn't have the cost listed anywhere on the book itself. Here is the link to the newest edition on Amazon (which happens to be the third edition still, so I guess there isn't a more recent version after all):

It's not cheap, but over the last couple of years I have referred to it a number of times for myself, and even more for other people. If you have the spare cash, I would say it would be a good buy. If you buy it through their 'used' sections, all the better.
The section on rats is very small, and is grouped together under 'rodents'. The main portion of the book deals with birds. Other animals covered include...
Fish
Amphibians
Reptiles
Birds
Sugar Gliders
Hedgehogs
Rodents (rats, mice, gerbil, hamster, Guinea pig, chinchilla, prairie dog)
Rabbits
Ferrets
Miniature Pigs
Primates
Wildlife (various) - great information on rehab and orphaned baby animals.
It is really worth it.
Of course, if anyone wants any information that it might contain, before going into your vet or whatnot, please always feel free to ask me to check it.
