FDA Compounding Rules

Meaning

FDA Compounding Rules are the specific federal regulations and comprehensive guidelines established by the U.S. Food and Drug Administration that govern the highly specialized practice of pharmaceutical compounding. These rules are designed to delineate the differences between traditional compounding pharmacies (503A) and outsourcing facilities (503B), imposing rigorous requirements on quality control, facility standards, and the precise circumstances under which medications may be customized. Strict adherence to these rules is legally mandated to ensure both patient safety and the quality assurance of all customized medications.
