What is Ketamine Therapy?

Originally developed and approved by the FDA as an anesthetic, ketamine is becoming a groundbreaking option for those who struggle with treatment-resistant mental health conditions. But what exactly is ketamine therapy? 

Ketamine therapy involves the administration of controlled doses of ketamine under the supervision of a doctor, usually through intravenous (IV) infusions, intramuscular injections, nasal sprays, or lozenges. It’s typically not a first-line treatment; however, it may be considered after failed attempts at other traditional treatments. Keep reading to learn more about ketamine therapy, what you can expect during treatment, as well as the benefits and risks of this innovative treatment.

What Does Ketamine Therapy Treat?

Ketamine therapy shows promise for many mental health conditions that haven’t responded to standard treatments, like: 

  • Treatment-resistant depression
  • Suicidal ideation
  • Post-traumatic stress disorder (PTSD)
  • Anxiety disorders
  • Obsessive-compulsive disorder (OCD)
  • Chronic pain conditions

In 2019, the FDA approved intranasal esketamine (Spravato), a derivative of ketamine, specifically for treatment-resistant depression. Treatment-resistant means a person has tried at least two different traditional antidepressants at adequate doses for sufficient time periods without seeing any significant improvements. 

How Does Ketamine Therapy Work in the Brain?

Conventional antidepressants target serotonin, norepinephrine, or dopamine systems, while ketamine works a little differently. Here’s how: 

  1. Ketamine blocks N-methyl-D-aspartate (NMDA) receptors in the brain’s cortex. This modulates the release of the excitatory neurotransmitter glutamate. 
  2. Ketamine increases synaptic connections. Research from Massachusetts General Hospital traced ketamine’s effects to three brain regions
    • The prefrontal cortex (responsible for planning and executive functions)
    • The hippocampus (influences memory formation)
    • The posteromedial cortex (likely responsible for the dissociative effects)
  3. Ketamine promotes neural plasticity by stimulating BDNF, a protein in the brain that supports the survival and growth of neurons. 

 

These mechanisms help explain why ketamine can work quickly when other treatments fail. By temporarily disrupting established neural patterns and promoting new connections, ketamine may essentially reboot certain brain circuits involved in mood regulation. 

Is Ketamine Addictive? 

Ketamine does have the potential for misuse; however, because it doesn’t activate the same reward pathways as highly addictive substances like opioids, compulsive use is less likely. Additionally, when used for mental health treatment, doses are lower than those used recreationally, and treatment programs include monitoring and screening for safety. 

That said, individuals with a history of substance use disorders may have increased vulnerability to developing a problematic relationship with ketamine.

The Ketamine Treatment Process

Before starting ketamine therapy, you’ll need a consultation with a qualified healthcare provider to review your medical and psychiatric history, current medications, and treatment goals. Based on the information gathered during this appointment, your doctor will then create a customized treatment plan. 

Ketamine treatment usually involves several sessions spread out over a few weeks, but this can vary depending on your provider. Your doctor may also recommend including psychotherapy to your treatment so you can get the most benefit. 

How to Prepare for Ketamine Therapy

Since ketamine therapy can alter your state of consciousness, it’s important to mentally and physically prepare yourself before each session. Here’s how: 

  1. Step 1: Detox Your Mind and Body. Avoid stimulants and depressants when possible (e.g., coffee and alcohol) while continuing any prescribed medications unless otherwise directed by your doctor. Avoid toxic social media or news as well for a clear mind. 
  2. Step 2: Practice Healthy Habits. Write down any goals and intentions you have for treatment and practice relaxation techniques like meditation or deep breathing. Consider attending a therapy session before treatment–research suggests combining ketamine with psychotherapy may maximize and extend benefits of treatment. 
  3. Step 3: Set Yourself Up For Success. Wear comfortable clothing the day of your procedure and arrange for someone to accompany you home after treatment. You’ll also want to make sure your schedule is clear for the remainder of the day after your session.

Not only will being prepared make the experience more pleasant, but it will also set you up to reap the benefits from treatment. In a recent study, researchers exposed patients receiving ketamine therapy to positive conditioning (e.g., pairing positive words with photos of the patient or smiling strangers) and found that they continued to report a decrease in the severity of their depression symptoms up to one month after treatment. This confirms the promotion of neural plasticity. 

What to Expect During Ketamine Therapy

During a ketamine treatment session, patients will relax in a reclining chair in a calm environment with eye shades and gentle music. These sessions usually last from 40 minutes up to an hour and may result in: 

  • Feelings of dissociation
  • Changes in perception of time, space, or body
  • Emotional releases or insights
  • Relaxation or dreamlike states 

While these effects are normal, medical staff are on standby monitoring vital signs and psychological responses. Interestingly, research suggests that dissociative effects experienced during treatment may actually predict better antidepressant responses. This means the altered consciousness state that ketamine produces might be connected to its therapeutic benefits.

The Benefits of Ketamine Therapy

Even though it’s still being researched, ketamine therapy has already shown to have several benefits: 

  • Often works within hours or days, compared to weeks or months for traditional antidepressants
  • Helps many patients who haven’t responded to multiple medication trials
  • Significantly decreases suicidal ideation compared to other common antidepressants
  • At least as effective as electroconvulsive therapy (ECT) for treatment-resistant depression without psychosis, with fewer side effects
  • May encourage the formation of new thought patterns and behaviors when combined with therapy

Risks and Side Effects of Ketamine Therapy 

While promising, ketamine therapy isn’t without risks. Potential side effects include: 

  • Dissociation
  • Dizziness or nausea
  • Mild increases in blood pressure and heart rate
  • Drowsiness and fatigue
  • Visual or perceptual disturbances
  • Headache

Less common but more serious risks include: 

It’s important to note that ketamine is not FDA-approved for psychiatric disorders (except for Spravato/esketamine for treatment-resistant depression), and many insurers consider it experimental, which may affect coverage.
