Ketamine clinics are outpatient medical facilities where patients receive low-dose ketamine treatments, primarily for depression that hasn’t responded to standard medications and for certain chronic pain conditions. These clinics have grown rapidly across the United States over the past decade, offering a treatment that works through a completely different brain mechanism than traditional antidepressants. Most sessions involve sitting in a comfortable room for one to two hours while the drug is administered through an IV, an injection, or a nasal spray, with medical staff monitoring you throughout.
Conditions Treated at Ketamine Clinics
The core use is treatment-resistant depression, meaning depression that hasn’t improved after trying two or more standard antidepressants. Ketamine works on a different signaling system in the brain than conventional medications, which is why it can help people who haven’t found relief elsewhere. The FDA has approved esketamine (a nasal spray form sold as Spravato) specifically for treatment-resistant depression in adults and for major depressive disorder with acute suicidal thoughts or behavior.
Beyond depression, many clinics also treat PTSD, anxiety disorders, and chronic pain syndromes. The chronic pain applications draw on ketamine’s long history as an anesthetic, using much lower doses to interrupt pain signaling pathways that have become overactive. These uses are considered off-label, meaning the drug is being prescribed based on clinical evidence and physician judgment rather than a specific FDA approval for that condition.
How Ketamine Is Administered
Clinics use three main delivery methods, and the one you receive shapes both the experience and the cost.
- IV infusion: The most common method at standalone ketamine clinics. A small catheter delivers ketamine directly into a vein over roughly 40 minutes, allowing precise dose adjustments in real time. This is the form with the longest research track record for depression.
- Intramuscular injection: A single shot, typically in the upper arm or thigh. The onset is slightly slower than IV but faster than nasal delivery. Some clinics prefer this method because it’s simpler to set up and doesn’t require IV access.
- Nasal spray (Spravato): The only FDA-approved form for depression. You self-administer the spray under direct observation of a healthcare provider. Because of its FDA approval, this is the version most likely to be covered by insurance.
What a Typical Treatment Schedule Looks Like
Treatment generally happens in two phases. The first is an initial trial of three to five sessions, sometimes called a “ketamine challenge,” where you receive infusions every other day or twice per week. This short burst helps determine whether your body responds to ketamine at all. Not everyone does, and clinics use this window to assess whether continuing makes sense.
If you respond well, the next phase typically involves twice-weekly sessions for four to five weeks, then a gradual taper. After that, some patients move to maintenance sessions spaced further apart. The guiding principle, according to the American Psychiatric Nurses Association, is that the number and frequency of treatments should be limited to the minimum necessary to maintain the clinical response. Some people need a booster every few weeks, others every few months, and some find the benefits hold without ongoing treatment.
What Happens During a Session
Ketamine clinics look nothing like a hospital. Most aim for a calming environment with dim lighting, comfortable recliners, and ambient music. This isn’t just aesthetics. The physical setting and your emotional state going in both influence how the experience unfolds and how effective the treatment tends to be. Clinics that incorporate psychotherapy often spend time before each session helping you set intentions and afterward helping you process whatever came up.
During the infusion itself, you’ll likely feel dissociation, a sensation of being detached from your body or surroundings. Some people describe it as dreamlike or floating. Your vital signs are monitored throughout, and a healthcare provider stays with you or nearby. After the drug is administered, you’re required to remain at the clinic for observation. For Spravato specifically, the FDA mandates a minimum two-hour post-administration monitoring period, during which staff check for lingering sedation, dissociation, and changes in blood pressure. You won’t be allowed to drive yourself home.
Who Works at These Clinics
Ketamine is a controlled substance, so anyone prescribing or administering it needs specific credentials and a DEA registration. Prescribers include physicians (MDs and DOs), nurse practitioners, psychiatric mental health nurse practitioners, certified registered nurse anesthetists, and physician assistants. Registered nurses can administer the drug in most states under the supervision of a licensed provider, though a few states have restrictions. Some states require that supervising provider to be a physician specifically.
The professional background of the clinic’s lead provider varies widely. Some clinics are run by psychiatrists who integrate ketamine into a broader mental health treatment plan. Others are led by anesthesiologists or nurse anesthetists whose expertise centers on the pharmacology and safe administration of the drug. Clinics that offer Spravato must go through a separate FDA certification process called a REMS program, which requires staff training on sedation and dissociation risks, established monitoring procedures, and detailed record-keeping for every session.
Cost and Insurance Coverage
This is where the distinction between IV ketamine and Spravato matters most. IV ketamine infusions typically cost $400 to $600 per session, with a median around $500. Intramuscular injections run slightly less, in the $275 to $400 range. Insurance does not cover either of these. Because IV and IM ketamine are used off-label for depression, the entire cost is out of pocket, and an initial course of six sessions can easily reach $2,400 to $3,600.
Spravato, being FDA-approved, opens the door to insurance reimbursement. Without any insurance, a single Spravato session runs $800 to $1,300. With commercial insurance, the out-of-pocket cost typically drops to $140 to $450 per session. The manufacturer also offers a subsidy program that can bring costs down to $0 to $62 per session for patients with commercial insurance who go through prior authorization. Over six months, that subsidy can reduce total costs from roughly $9,450 to as little as $0 to $1,300. The subsidy doesn’t apply to Medicare, Medicaid, or VA coverage.
The Role of Therapy Alongside Ketamine
Ketamine on its own can produce rapid improvements in mood, sometimes within hours of a first infusion. But a growing number of clinics pair the drug with psychotherapy, and the combination appears to strengthen and extend the benefits. The idea is that ketamine temporarily increases the brain’s ability to form new connections, creating a window where talk therapy may be especially productive.
Integration therapy, as it’s often called, typically happens in sessions after each infusion. A therapist helps you make sense of the thoughts, emotions, or imagery that surfaced during the dissociative experience and apply any insights to your daily life. Not all clinics offer this. Some provide the infusion only and leave therapy coordination to your outside providers. If sustained mental health improvement is your goal, it’s worth asking whether a clinic includes integration support or operates purely as an infusion service.
Who Should Not Receive Ketamine
Ketamine raises blood pressure temporarily, so uncontrolled hypertension is a concern. People with a history of psychosis or active psychotic symptoms are generally not candidates, since the dissociative effects could worsen their condition. Active substance use disorders, particularly involving ketamine or other dissociatives, also raise red flags. Pregnancy, certain cardiovascular conditions, and elevated intracranial pressure are additional reasons a clinic may decline to treat someone. A reputable clinic will conduct a thorough medical and psychiatric screening before your first session.
