What is compounding?

Compounding is a way for licensed pharmacists to create a customized medication that meets your pet’s specific needs. Compounding pharmacists mix or change one or more FDA-approved medications to prepare a special medication for your pet. For example, if a medication is only available in pill form, the pharmacist might create it in liquid, cream, soft chew, capsule, powder or paste form.

Why do some pets need compounded medications?

Your pet may have a specific health need that cannot be addressed by an FDA-approved drug. For example:

  • Your pet has trouble taking pills but will take medication in a flavored liquid or other form.
  • Your pet needs medication in a strength that is not commercially available.
  • Your pet is allergic to a specific ingredient in a medication.

Always talk with your veterinarian about any concerns you have about your pet’s health so they can prescribe a treatment for your pet’s unique needs.
