Buspirone

Anxiolytic

Sedating: No Driving: None QT risk: Low Akathisia: Low Metabolic: Low Prolactin: Low t½: 3 h Tmax: 1 h

Marketed as the “non-benzo benzo,” but it never really lived up to the hype. Buspirone is an anxiolytic that works on serotonin 5-HT1A receptors, not GABA. That means no buzz, no sedation, and no dependence — but also no quick relief. It takes weeks to work (if it works at all), and many people feel it’s basically a placebo with side effects. Still prescribed for generalised anxiety in the UK, but rarely anyone’s first choice.
