What is ketamine therapy?
Ketamine is a medication that has been used safely in hospitals for decades. In recent years, it has found a new role in helping people with difficult-to-treat mental health conditions.

How does it work?
Ketamine affects the brain in ways that are different from traditional medications. It acts on the NMDA receptor system, increasing glutamate activity and promoting neuroplasticity — the brain’s ability to form new connections.
For many patients, this creates a window of time where old mental patterns soften, new perspectives arise, and emotional healing can begin.

What types of treatment exist?
Ketamine can be used in different ways:
- IV infusion (intravenous)
- IM injection (intramuscular)
- Nasal spray (Spravato® — FDA-approved for depression)
- Lozenges or troches (dissolve in the mouth)
- Ketamine-assisted psychotherapy (KAP) — where ketamine sessions are combined with therapy
Each method has its own uses, benefits, and drawbacks. A trained provider can help choose the right one for each person.
