Ketamine Infusion Therapy
Ketamine infusion therapy is a rapid-acting, off-label medical treatment for severe, treatment-resistant depression, anxiety, PTSD, and chronic pain, often providing relief within hours. It works by using low-dose intravenous infusions to increase neural connectivity. It is administered in clinics, typically in a series of six sessions over several weeks. [1, 2, 3, 4, 5]
Key Aspects of Ketamine Infusion Therapy
- Conditions Treated: Primarily used for treatment-resistant depression (TRD), suicidal ideation, PTSD, addiction, and complex regional pain syndrome (CRPS).
- How it Works: Ketamine, a noncompetitive NMDA receptor antagonist, boosts glutamate, which aids in repairing synaptic connections between neurons, essentially "rewiring" pain or depression pathways.
- The Procedure: Administered intravenously (IV) in a controlled, comfortable clinical environment, usually over 40–60 minutes. Patients remain conscious but often feel a dissociative, dream-like state, sometimes accompanied by dizziness or nausea.
- Effectiveness & Timing: Unlike traditional antidepressants that take weeks, ketamine can show results within hours or days. Many patients feel significant relief, lasting for weeks to months.
- Side Effects: Generally mild and temporary, including dissociation ("out-of-body" feeling), increased blood pressure, nausea, dizziness, and blurred vision.
- Costs: Often not covered by insurance, requiring significant out-of-pocket payment. [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
