Know the Difference
503A vs 503B — what it means for your practice.
Not all compounding pharmacies are the same. Understanding the distinction helps you source smarter, stay compliant, and serve your patients better.
Traditional compounding pharmacies.
503A pharmacies compound medications for individual patients based on avalid prescription. These are patient-specific, meaning each compound ismade to order for a named individual.
FDA-registered outsourcing facilities.
503B facilities can produce large batches of compounded drugs without patient-specific prescriptions. They are federally regulated by the FDA and subject to cGMP standards — the same rigor as commercial manufacturers.
