The more you know about compounding, the better equipped you are to decide when compounding is the best choice for your patients. The following resources will help explain the what, why, and how of compounding. If you have more questions, check out the Frequently Asked Questions (FAQ) section. And, of course, our representatives are always happy to help!
United Sates Pharmacopeial Convention (USP)
The USP helps protect and improve the health of people around the world. Establishing standards where everyone can be confident in the quality in health and healthcare. The USP established standards for compounding quality nonsterile preparations.

The AVMA professional policies provide guidance on the practice of veterinary medicine of which includes compounding. These policies are developed by peers on behalf of the profession.
Compounding is the customized preparation of a medicine that is not commercially available otherwise. The American Veterinary Medical Association (AVMA) states that compounding consistent with FDA Extra-Label Drug Use regulations is “the customized manipulation of an approved drug(s) by a veterinarian, or by a pharmacist upon the prescription of a veterinarian, to meet the needs of a particular patient.”
Common forms of drug manipulation in veterinary compounding include
The decision to use compounding is based on medical necessity. These reasons are the most common:

The assurances that you have with an FDA-approved drug do not apply to compounded drugs. Compounded medications are similar to “off-label” use of FDA-approved drugs. When the FDA approves a drug as safe and effective, the approval only applies to the specific disease or condition for which the drug was tested, but physicians often prescribe these medications to treat other conditions when doing so is deemed to be in the best interest of the patient. If you believe that compounding will best treat a patient, ask yourself these questions:
If you notice unexpected in drug precipitation, visible flocculant material, color change, or separation of liquid phases with a compounded preparation, the cause may be improper storage, transport, or an unexpected chemical/physical drug interaction. If you have questions about the efficacy or safety of the preparation, please contact the compounding pharmacist.
Veterinary compounding is regulated by both the federal government (Food and Drug Administration/FDA) and state governments. The FDA regulates compounding for animal patients as a subpart of its Extra-Label Drug Use (ELDU) rules, and publishes a Compliance Policy Guide (CPG) which describes how it regulates compounding for animals and which activities it defers to the state. The FDA generally defers day-to-day regulation of compounding by veterinarians and pharmacists to state authorities. The state boards of pharmacy oversee pharmacy practices within the states, while the state veterinary medical boards oversee the practice of veterinary medicine, including prescribing.
Before using a pharmacy, veterinarians should also consider whether the pharmacy is compliant with the United States Pharmacopeial Convention (USP) for nonsterile and sterile compounding.
The U.S. Food and Drug Administration (FDA) requires that compounded medications be modified versions that use only FDA-approved medications. If they use ingredients not approved by the FDA for humans or animals, the FDA considers them new drugs that require approval to be sold legally. For example, your pet may have a condition that needs to be treated with eardrops, yet the medication is only available as a tablet. Your veterinarian can request that the compounding pharmacy create an eardrop version of that tablet, so your animal can get the treatment it needs.
Compounded medications may be created outside these guidelines to relieve suffering in certain situations. Veterinarians and pharmacists consult carefully in such cases to asses compliance with state and federal law and FDA guidelines. The U.S. government continues to assess compounding to improve regulation clarity. We’re happy to answer any questions or concerns.
No, they are very different. Compounded preparations are not equivalent to FDA-approved generic drug products, which requires a demonstration of bioequivalence of safety and efficacy with the pioneer FDA-approved drug product. In contrast to generic drugs, compounded preparations lack FDA approval.
Note: Avoid any pharmacy that claims to sell compounded preparations that are identical to commercially available FDA-approved products. Legitimate compounding is prescription-driven and based on the need to customize a preparation for an individual patient’s needs.
A bulk drug substance is an active pharmaceutical ingredient (API) or pure chemical used to produce a drug. The FDA-approved version is the actual finished form containing the ingredient.
Compounding is a long-established pharmacy practice than enables veterinarians to prescribe medicines prepared by pharmacists specifically to meet a patient’s needs. Many animals have unique needs that cannot be met by off-the-shelf prescriptions, and compounding allows the safe, accurate preparation of drugs to effectively treat those needs. Usually, a compounded drug will provide a dosage, flavoring, combination, or administration form that is not available commercially. For example, a cat that refuses to allow pilling at home may be prescribed a flavored liquid that it will take. Your veterinarian can explain in detail the reasons a compound preparation may be necessary for your pet.
Understand that even though compounds may be necessary in certain medical situations, their use has both benefits and risks. Since compounded preparations do not receive FDA approval, their stability, safety, potency, and effectiveness cannot be assured. An approved drug is always preferable, but compounding plays an important role in animal health when such medications are unavailable.
No, not unless your veterinarian has specifically directed you to do so. Prescriptions for compounded medications are specifically written for individual animals; using one pet's compounded medication for another pet could harm your pet.
No. Only a veterinarian can prescribe a compounded medication for an animal.
