Pet Medications: Prescriptions & Over the Counter: United States Report

Report Overview

This report discusses US pet medication retail sales (both prescription and over-the-counter) in nominal US dollars for 2025.
This report provides a general overview of the retail market for medications for domesticated dogs and cats, with a focus on products purchased directly by consumers. The primary focus of this report is on the core types of antiparasitics/parasiticides – heartworm preventatives, flea/tick preventatives, and heartworm/flea combo products, and other dewormers (some of which also target other external parasites such as mosquitoes, flies, ear mites, lice, and sarcoptic mange, and/or other types of internal parasites such as hookworms, roundworms, whipworms, and tapeworms). “Flea/tick” can refer to products that treat only fleas and ticks, but can also refer to combination products that additionally treat worms, mites, etc., except heartworms. Also covered are market-shaping developments in other areas, including anxiety, pain management, cancer, cognitive dysfunction, and obesity/diabetes.
Animal health products for production animals and horses are excluded from this market analysis, as are nutritional supplements for companion animals, which are covered in Packaged Facts’ March 2026 report Pet Supplements in the US.
