Ketamine Therapy for Rapid Suicide Risk Reduction

Quick fact

A single infusion of ketamine can reduce suicidal ideation within hours, an effect that lasts for days to weeks. The FDA has approved a form of ketamine—esketamine nasal spray—for treatment-resistant depression, which includes suicidality as a target symptom.

Why this is interesting

What if a single dose of a medication could lift suicidal thoughts within hours—not weeks? Ketamine does exactly that, and it's changing how we think about treating the most urgent psychiatric emergencies.
