What is ketamine for depression?

(racemic ketamine, NMDA receptor antagonist)

Ketamine is an NMDA receptor antagonist originally used for anesthesia. At sub-anesthetic doses, it produces rapid antidepressant effects distinct from SSRIs or MAOIs. The mechanism is not fully understood but involves NMDA antagonism, increased BDNF, and rapid synaptogenesis. Ketamine works within hours to days in treatment-resistant depression, whereas SSRIs take weeks. A sublingual form (orally disintegrating tablet) allows at-home dosing under physician guidance. Dissociation (feeling detached from body or surroundings) is expected; your physician prepares you.

How ketamine works

  1. Day 1

    Your physician reviews your depression history, failed antidepressant trials, psychiatric status, blood pressure, substance use history, and suicide risk. Discusses ketamine's rapid action, expected dissociation, and risks.

    1
  2. Week 1

    First ketamine dose under physician supervision or in an office setting. Take as sublingual tablet. Expect dissociation (feeling detached, mild hallucinations) for 30-90 minutes. Rest and recover with a designated person.

    2
  3. Days 2-7

    Mood and depression symptoms often lift significantly within 24-72 hours. Some people report euphoria; this fades. Continue your other psychiatric medications unless your physician advises otherwise.

    3
  4. Weeks 2-4

    Your physician assesses your mood and response. Additional ketamine doses may be given on a schedule (e.g., weekly initially, then as-needed). Discuss maintenance and long-term plans.

    4
  5. Beyond

    Ketamine is continued only if response is sustained and risk is acceptable. Your physician monitors your mental state, substance use risk, and continued need at every visit.

The science of ketamine and rapid antidepressant action

Ketamine produces rapid antidepressant effects in treatment-resistant depression in multiple randomized controlled trials. Dissociation is short-lived and dose-dependent; it is managed by physician dosing.

Long-term ketamine safety is emerging. The controlled setting and sublingual (not IV) dosing reduces risks. Abuse potential and cognitive effects with chronic dosing require careful monitoring and clear protocols.

Important safety information and common side effects

Ketamine is a controlled substance (Schedule III in the US). It is prescribed only for treatment-resistant depression under careful physician oversight. Dissociation (feeling detached or hallucinating) is expected; your physician prepares you and controls the dose. Do not drive or operate machinery for 6-8 hours after dosing. Do not use ketamine if you have active or recent psychosis, uncontrolled high blood pressure, or hyperthyroidism. Tell your physician about any history of substance use, suicidal ideation, or psychosis. Ketamine carries abuse potential; use only as prescribed in a monitored setting. Stop and seek emergency care for severe dissociation, chest pain, very high blood pressure, or confusion lasting beyond expected time.

Frequently asked questions

How do I take Ketamine ODT?

Dissolved under the tongue, once a day. The starting prescription is 1 tablet (50 mg) each time. Your physician sets your own dose and it is printed on your label.

What strengths does Ketamine ODT come in?

The pharmacy carries 2: 50 mg, 100 mg. Your physician chooses which one you get.

How much arrives in each shipment?

30 tablets at the starting strength, shipped to your door from a licensed US pharmacy.

Is it a controlled substance?

Yes. The law requires a live video visit with the physician before it can be prescribed.

Is ketamine safe for depression?

Ketamine has strong evidence for treatment-resistant depression when prescribed and monitored by an experienced physician. The rapid antidepressant effect can be life-saving in severe cases. Dissociation, abuse risk, and cognitive effects require close oversight. Ketamine is not a first-line treatment; it is reserved for people who have not responded to standard therapy.

How fast does ketamine work?

Many people feel relief within hours to a day. Some feel changes within minutes of the first dose. Unlike SSRIs, which take 4-6 weeks, ketamine acts rapidly. The effect may plateau or fade over days; your physician decides on repeat dosing.

What is dissociation?

Dissociation is a temporary detachment from your body or surroundings. You may feel floating, see mild visuals, or lose track of time for 30-90 minutes. It is expected, reversible, and managed by dose. Your physician prepares you and stays present during dosing.

Can I become addicted to ketamine?

Ketamine has abuse potential. Use only as prescribed, in a monitored setting, by your physician. Avoid driving or operating machinery for 6-8 hours after a dose. Report any urge to use ketamine outside of medical supervision immediately.
