Compounded medications are not reviewed or verified by the FDA for safety, effectiveness, or quality and are not FDA-approved. Instead, compounded drugs may be prepared for patients who cannot be treated with an FDA-approved medication. Licensed healthcare providers should evaluate whether compounded medication is appropriate for individual patients. 503A pharmacies are required to comply with FDA rules, regulations, and applicable laws.
