The Food and Drug Administration (FDA) is a U.S. government agency responsible for protecting public health. It ensures that food is safe to eat, drugs are effective and safe for use, and medical devices work as intended. The FDA also regulates cosmetics and tobacco products, making sure they meet safety standards. To achieve its goals, the FDA conducts research, inspects facilities, and reviews product applications. It plays a crucial role in monitoring the safety of products like vaccines, prescription medications, and food additives. By overseeing these areas, the FDA helps maintain the health and well-being of the American public.
