Ketamine for Depression and Chronic Pain: What You Need to Know
Ketamine is used off-label for treatment-resistant depression and chronic pain. Learn how it works, what to expect, and where to find it.
What is Ketamine?
Ketamine is an anesthetic medication that has been used in medical settings since the 1960s. In recent years, it has gained attention for treating depression and chronic pain, particularly when other treatments have not worked.
How Ketamine Works
Unlike most antidepressants, ketamine works on different brain pathways. Instead of targeting serotonin, it affects glutamate, a neurotransmitter involved in mood regulation. This different mechanism means it can work for some people who have not responded to standard antidepressants.
What Ketamine is Used For
Ketamine is primarily used off-label for:
- Treatment-resistant depression (depression that has not responded to two or more antidepressants)
- Chronic pain conditions
- Bipolar depression
- Post-traumatic stress disorder (PTSD)
The FDA has approved esketamine (a form of ketamine) as a nasal spray for treatment-resistant depression.
How You Receive Ketamine
Ketamine can be administered as:
- Intravenous (IV) infusions at a clinic
- Intramuscular injections
- Nasal spray (esketamine)
- Oral tablets (off-label)
IV infusions typically happen weekly or several times per week for a set number of sessions.
What to Expect
Ketamine works faster than traditional antidepressants. Some people feel relief within hours or days, though results vary. The medication produces dissociative effects (feeling disconnected from your body or surroundings) during administration, which is temporary.
You will need medical supervision during ketamine treatment. Clinics should monitor your vital signs and psychological response.
Cost and Access
Ketamine clinics are available in many areas, though availability varies. IV ketamine is typically not covered by insurance. Costs range widely depending on location and clinic. Esketamine nasal spray may be covered by some insurance plans.
Finding Ketamine Treatment
You can find ketamine clinics through telehealth platforms and local mental health providers. Not all providers offer ketamine, so you may need to search specifically for clinics in your area or ask your current provider for a referral.
