Why this is significant: There is no currently known treatment to stop suicidal thoughts when they happen. Antidepressants take 4-6 weeks to start working, and they don’t work for everyone. Therapy also takes time. Our best option for acutely suicidal people is to lock them up in a psychiatric facility until they are no longer a threat to themselves.

Intravenous ketamine offers a glimpse of hope. A single dose appears able to alleviate suicidal ideation immediately after administration and for up to a week afterwards.
