Diazepam Brand Names in Australia
Diazepam is a well‑known benzodiazepine that has been used worldwide for anxiety, muscle spasms, and seizure disorders. In Australia, patients often encounter the drug under several brand names. This article outlines the most common Australian brand names, how they differ, and key points for safe use.
