For a pharmacy to be eligible for exemptions under section 503A, which of the following must they do?

To be eligible for exemptions under section 503A of the Federal Food, Drug, and Cosmetic Act, a pharmacy must adhere to current good manufacturing practices (CGMP). These guidelines are crucial as they establish quality criteria for the preparation of compounded medications. Compliance with CGMP ensures that the compounded drugs are manufactured in a way that meets safety, quality, and efficacy standards, which is essential for the protection of public health.

While other practices like disclosing financial relationships with suppliers or charging delivery fees can be part of a pharmacy's operations, they do not specifically pertain to the eligibility criteria under section 503A. Additionally, selling only non-prescription medications does not align with the intent of section 503A, which focuses on compounding for designated medical purposes. Thus, following CGMP is the critical requirement for a pharmacy seeking to take advantage of the exemptions provided under this legislation.
