Curious about different types of ketamine therapy? This guide explains IV, IM, oral, intranasal, and psychotherapy-assisted options so you know what to expect.
Ketamine therapy has gained recognition as a breakthrough treatment for depression, anxiety, PTSD, and chronic pain. While research confirms its rapid effectiveness, many patients have the same question: What are the types of ketamine therapy, and which one is right for me?
This article explores the main types of ketamine therapy, their unique benefits, and what patients can expect from each option.
IV Ketamine Infusion Therapy
IV infusion therapy is the most common and well-studied type of ketamine treatment.
How It Works
Ketamine is delivered directly into the bloodstream through an IV line. This allows precise control over dosage and steady absorption during the session.
Session Structure
IV sessions usually last 40–60 minutes. Patients remain seated or reclined in a calm environment while medical staff monitor blood pressure, heart rate, and comfort.
Effectiveness
Among the types of ketamine therapy, IV infusion has some of the strongest evidence for treating treatment-resistant depression. Many patients report relief within hours or days, even after multiple failed antidepressant trials.
Considerations
While highly effective, IV therapy can be costly, averaging $400–$800 per session. Insurance rarely covers this option, making affordability an important consideration.
Intramuscular (IM) Ketamine Injections
IM injections are another method of delivering ketamine under medical supervision.
How It Works
Ketamine is injected directly into a muscle, usually in the arm or thigh. Unlike IV infusions, IM injections deliver the full dose at once rather than gradually.
Session Structure
Sessions are typically shorter than IV infusions. Effects begin within minutes and last about 30–45 minutes.
Effectiveness
IM ketamine can be effective for patients who cannot tolerate IV lines or prefer a simpler procedure. However, the dose cannot be adjusted mid-session, making it less customizable than IV therapy.
Considerations
Because IM injections are delivered as a single dose, side effects like dizziness or dissociation may be more intense initially.
Oral and Sublingual Ketamine
Oral and sublingual options are increasingly offered, especially in at-home therapy models.
How It Works
Patients take ketamine as tablets or dissolvable lozenges. Sublingual (under the tongue) administration allows faster absorption than standard oral tablets.
Session Structure
Depending on the program, patients may take oral ketamine at home with telehealth monitoring, or in-clinic with provider supervision.
Effectiveness
Oral ketamine has lower bioavailability compared to IV or IM methods, meaning the body absorbs less of the medication. However, many patients still experience benefits, especially when paired with therapy or integration support.
Considerations
While more affordable ($100–$250 per session), at-home ketamine requires strong safety protocols and professional guidance to avoid misuse.
Intranasal Ketamine (Spravato Esketamine)
Spravato is the only FDA-approved ketamine treatment for mental health conditions, making it one of the most accessible options.
How It Works
Spravato is an esketamine nasal spray administered in a certified clinic. Patients self-administer under provider supervision, followed by a required two-hour observation period.
Insurance Coverage
Unlike other types of ketamine therapy, Spravato is often covered by insurance because of its FDA approval. This makes it a more financially viable option for many patients.
Effectiveness
Spravato is specifically approved for treatment-resistant depression and major depressive disorder with suicidal thoughts. Studies show it provides rapid symptom relief, especially when combined with oral antidepressants.
Considerations
Patients may still face copays or session limits, and not all clinics are certified to provide Spravato.
Ketamine-Assisted Psychotherapy (KAP)
Ketamine-assisted psychotherapy (KAP) integrates ketamine treatment with talk therapy for a combined healing approach.
How It Works
Patients receive a low-to-moderate dose of ketamine, then work with a therapist to process emotions, memories, or trauma that arise during the session.
Session Structure
KAP sessions typically last longer than IV infusions, as they combine medication with guided therapy. Patients may engage in reflection, conversation, or mindfulness exercises during treatment.
Effectiveness
This approach is especially popular for PTSD, trauma, and complex emotional challenges. By combining ketamine’s neuroplasticity-enhancing effects with psychotherapy, KAP may accelerate healing and integration.
Considerations
KAP is less widely available than other methods and may not be covered by insurance. However, its popularity is growing due to its holistic benefits.
