Could a single ketamine shot curb suicidal urges in the ER?
NCT ID NCT06085937
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests whether a single low-dose injection of ketamine is safe and practical for adults who come to the emergency department with severe suicidal thoughts. Researchers will monitor side effects and ask staff about their experience. If successful, it could offer a quick way to ease suicidal thinking while patients wait for psychiatric help.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ketamine
- What this could lead to
- If it works, this could provide a fast-acting option to reduce suicidal thoughts in the emergency room, buying time for further psychiatric care.
- What could go wrong
- This is a very early Phase 1 trial with only 50 participants, so it may not prove effective or safe for broader use. Ketamine can cause side effects like dissociation or blood pressure changes.
