Veterinary Compounding Pharmacy

What is a Veterinary Compounding Pharmacy?

A veterinary compounding pharmacy combines high quality, active pharmaceutical ingredients to create species-specific formulations, delivery systems and dosages of veterinary medications. Our registered pharmacists and your family veterinarian will work together to determine the dose and the most effective delivery system for your pet; e.g. capsule, flavored chew, suspension, solution, cream, suppository. The compounded drug will be created from the highest quality ingredients to meet your pet’s unique needs.

Among the benefits of compounding medications is the ability to tailor the delivery method to the pet: If a pet is unwilling to take bitter tasting liquid, the process becomes a struggle for the owner and the pet. If the same drug can be compounded into a capsule or a tasty flavored treat, neither the owner nor the patient is traumatized, and necessary medications can be administered without anxiety.

Our pharmacy is currently licensed in Massachusetts and New Hampshire, with more states to come! For your convenience, ask about shipping within each of these states and have your pet’s medications delivered to your door.

Pet Owners with a valid prescription may order medications from other states, but they must pick up in person at an Ethos hospital in either Massachusetts or New Hampshire (we cannot ship outside either state). If you are close enough that this is an option for you, please work with our compounding team to arrange a pick up location and date.
