FDA regulations refer to the rules and guidelines set by the Food and Drug Administration (FDA) in the United States to ensure the safety, efficacy, and quality of food, drugs, medical devices, cosmetics, and other products regulated by the agency. These regulations cover a wide range of topics, including product labeling, manufacturing practices, clinical trials, advertising, and product recalls. Compliance with FDA regulations is mandatory for companies and individuals involved in the production, distribution, and sale of FDA-regulated products to protect public health and promote consumer confidence. Violations of FDA regulations can result in penalties, fines, and legal action.
