Drug Monographs

Review current details on 720+ drugs

Each Plumb’s drug monograph covers current dosages, adverse effects, mechanisms of action, administration/storage, pharmacology for animals, and more. Search by drug or trade name from any page. Browse the full library—including helpful appendices—from the Drug Monographs page.

Jump to the details you need

At the top of each drug monograph, quick links to Dosages and Dosage Forms will take you to these frequently accessed sections. Or use the table of contents on the left side of each drug monograph to navigate directly to the section you need.

Stay current

Each Plumb’s drug monograph is continually updated by our expert team of veterinarians and veterinary pharmacists. Watch for the New and Updated tags.


Explore helpful appendices

Don’t miss practical information on drug store toxins in small animal species, abbreviations used in prescription writing, and more.

Drug Interaction Checker

Check for potential drug interactions

Our veterinary‑specific drug interaction checker allows you to add as many drugs as needed to get animal‑specific guidance on potential drug‑to‑drug interactions. All information is based on current evidence and continually reviewed by our expert team of veterinarians and veterinary pharmacists. Type in the drug names and select matches from the dropdown list to get results.

Evaluate risk based on five classification levels

This tool currently covers 37,000+ interactions between frequently used drugs, with new interactions being continually added. To learn more about a classification, click on the blue information icon .

Avoid a dangerous information gap

Human‑specific drug interaction tools don’t list veterinary drugs or species‑specific data. The Plumb’s drug interaction checker contains animal‑specific information and helps ensure safer dispensing for your veterinary patients.

This tool is undergoing continual medical review and content updates. Results generated by the interaction checker represent one‑to‑one drug interactions only, and they are intended to supplement the knowledge and clinical judgment of medical professionals using this tool. Please consult the prescribing veterinarian before making any adjustments to an animal’s prescription.
Conversion Calculator

Click on the blue calculator icon  from any page to convert between common units (like lb/kg, oz/g) and easily calculate doses.

Add special instructions

Whether you’re printing or emailing, you can include special instructions for the pet owner. For example, you might note any additional instructions their veterinarian provided with the prescription, pass along administration information, or document any discussion with the pet owner during the dispensing process.
