Ketamine Therapy for Depression
Ketamine therapy uses low dose ketamine (originally an anesthetic) to treat major depressive disorder, especially when other antidepressants have failed. It is administered via:
- IV infusions (most common and studied)
- Intramuscular injections
- Nasal spray (Esketamine / Spravato, FDA approved)
- Oral lozenges or at home options (emerging)
It is particularly popular for rapid relief many patients feel improvement within hours to days, unlike traditional antidepressants that take 4–6 weeks.
How Does Ketamine Work for Depression?
Ketamine works differently from SSRIs/SNRIs:
- It blocks NMDA receptors (part of the glutamate system).
- This triggers a surge in glutamate, which stimulates AMPA receptors.
- The result is increased brain derived neurotrophic factor (BDNF), leading to synaptogenesis, the rapid growth of new neural connections.
- It also reduces inflammation and may affect opioid receptors and astrocytes.
Key advantage: It promotes neuroplasticity (the brain’s ability to rewire itself), helping break negative thought patterns quickly.

Ketamine vs Esketamine (Spravato)
| Aspect | IV Ketamine | Esketamine (Spravato) |
|---|---|---|
| Form | Intravenous infusion | Nasal spray |
| FDA Approval | Off-label for depression | Approved for treatment resistant depression (2019) |
| Effectiveness | Often slightly higher response rates | Very effective, but sometimes lower |
| Speed | Faster onset (hours) | Slightly slower |
| Administration | Clinic setting, monitored | Clinic setting (self-administered under supervision) |
| Cost | Usually cash-pay (~$400–$800/session) | Often insurance covered |
| Side Effects | More dissociation possible | Generally milder |
Bottom line: IV ketamine is frequently reported as slightly more effective and faster, while Spravato is easier to access via insurance.5. Treatment-Resistant Depression (TRD) & KetamineKetamine shines here. Studies show:
- 50–70% response rate (significant symptom reduction)
- 30–50% remission rate after a full course
- Particularly helpful for patients who failed 2+ antidepressants
- Can rapidly reduce suicidal ideation
Effects typically last 1–2 weeks per treatment, so maintenance is often needed.Important Notes (2026):
- Ketamine is not a cure; best combined with therapy, lifestyle changes, and ongoing care.
- Side effects can include dissociation, elevated blood pressure, nausea, and (with long-term recreational use) bladder issues.
- It should only be done under medical supervision in licensed clinics.
