The Therapeutic Goods Administration (TGA) is a unit of the Australian Government Department of Health and Ageing. The TGA approves and monitors prescription and non-prescription drugs (including herbal products), medical supplies and devices, and blood and biological products. Risks to users are assessed prior to product introduction, and manufacturers are regularly audited for efficacy, quality and safety. Manufacturers are required to report adverse drug effects to the Adverse Drug Reactions Advisory Committee (ADRAC) of the TGA; reporting by medical professionals and consumers is voluntary. ADRAC notifies medical professionals and the public by recalls and alerts on its website and publications.
