The purpose of this legislation, known as the Safeguarding Americans from Fraudulent and Experimental Drugs Act of 2025, is to enhance the regulation of compounding pharmacies and outsourcing facilities. This aims to ensure the safety and effectiveness of compounded drugs, which are custom-made medications that are not commercially available. Key provisions of the law include stricter definitions and limits on how many times a pharmacy can compound a drug that is similar to an existing commercially available product.
