This part applies to compounding of a product from approved animal or human drugs by a veterinarian or a pharmacist on the order of a veterinarian within the practice of veterinary medicine. Nothing in this part shall be construed as permitting compounding from bulk drugs.
Extralabel use from compounding of approved new animal or human drugs is permitted if:
All relevant portions of this part have been complied with;
There is no approved new animal or approved new human drug that, when used as labeled or in conformity with criteria established in this part, will, in the available dosage form and concentration, appropriately treat the condition diagnosed.

The compounding is performed by a licensed pharmacist or veterinarian within the scope of a professional practice;
Adequate procedures and processes are followed that ensure the safety and effectiveness of the compounded product;

Guidance on the subject of compounding may be found in guidance documents issued by FDA.
