Ketamine Therapy Cost: A Complete Breakdown by Treatment Type

A ketamine booster usually costs the same as one session of the treatment it maintains: $400 to $800 for an IV ketamine booster infusion and $200 to $400 for an intramuscular (IM) booster, typically repeated about once a month after a six-infusion starting course of $2,400 to $4,800. Across every format, ketamine therapy costs range from $100 to $350 a month for compounded troches with a prescriber to $600 to $900 per session for Spravato (esketamine) nasal spray before insurance, and Spravato is the only form insurers commonly cover.

Ketamine is a dissociative anesthetic and NMDA receptor antagonist that clinics use off label for treatment-resistant depression (TRD), meaning depression that has not responded to at least two antidepressants. The evidence for TRD comes from randomized trials, including Zarate and colleagues at the National Institute of Mental Health (2006), Murrough and colleagues (2013), and a 2023 New England Journal of Medicine trial led by Amit Anand that found IV ketamine noninferior to electroconvulsive therapy (ECT) for nonpsychotic TRD. Results vary from person to person, and the response often fades without maintenance, which is why boosters drive the long-term bill.

Pricing is opaque because it depends on the route of administration, the clinical setting and the provider, and insurance coverage is a patchwork. According to the FDA (2023), ketamine is not FDA approved for any psychiatric disorder, so IV, IM and at-home ketamine for depression are almost always paid in cash, while Spravato carries an FDA approval that insurers recognize. The ranges quoted throughout reflect what clinics commonly charge; your own quote can sit above or below them.

Ketamine Therapy Cost by Treatment Type

The cost of ketamine therapy varies dramatically depending on the route of administration, the clinical setting, and the provider. Here is the full breakdown:

IV infusion is the most studied format, IM injection is the lower-cost in-clinic format, Spravato is the only FDA approved format for depression, and at-home oral or sublingual programs cost the least per month with the least supervision. Each format also carries its own booster schedule, which matters more to your annual budget than the price of the first session.

How Much Does a Ketamine Booster Cost?

A ketamine booster costs $400 to $800 per IV infusion and $200 to $400 per IM session, because most clinics charge the same rate for a booster as for an infusion in the initial series. Boosters, also called maintenance infusions, are single sessions scheduled after the first six to keep a response going. Most patients start at about one booster a month, and some can stretch the interval to every six to eight weeks.

What changes the price of a ketamine booster?

Booster pricing moves with the same factors as the initial series: the clinic's market, the clinician supervising the session, and whether the fee bundles vital-sign monitoring and recovery time. Sessions may be overseen by an anesthesiologist, a certified registered nurse anesthetist (CRNA), an emergency physician, a psychiatrist or a psychiatric nurse practitioner. Some clinics extend package discounts to boosters and others charge full price for every maintenance visit, so ask for the booster rate in writing before you book the first infusion.

Spacing matters as much as price. A patient who holds a response with a booster every eight weeks spends about half as much each year as one who needs a booster every four weeks, so the schedule your clinician sets after the initial course is the biggest variable in long-term ketamine therapy cost.

Ketamine booster cost in the Pacific Northwest

Searches for ketamine booster cost in the Northwest mostly come from Washington, Oregon and Idaho, where most residents live along the I-5 corridor from Seattle to Portland, with further population centers around Spokane and Boise. Regional booster prices are not published in a consistent way, so treat the national ranges above as the starting point and compare written quotes from several clinics. You can browse ketamine clinics in Washington, ketamine providers across Oregon and Idaho ketamine therapy clinics, then ask each one for its booster rate.

Oregon also runs a state-licensed psilocybin services program, a separate cash-pay option that is not ketamine and has its own costs and rules; the psychedelic therapy overview explains how it differs.

IV Ketamine Infusions: The Clinical Gold Standard

IV ketamine infusions are the most studied and most commonly referenced form of ketamine therapy for depression. They are administered in a clinical setting, typically a dedicated ketamine clinic, a psychiatrist’s office with infusion capability, or an anesthesiology practice.

What you are paying for:

• The ketamine medication itself (the cheapest part, generic ketamine is inexpensive)
• IV access and monitoring equipment
• A medical professional monitoring you throughout the 40-60 minute infusion
• Post-infusion recovery time and observation (usually 30-60 minutes)
• Clinical overhead: rent, insurance, staff, medical supplies

Standard protocol: 6 infusions over 2-3 weeks (typically Monday-Wednesday-Friday for two weeks). Each infusion lasts about 40 minutes at a dose of 0.5 mg/kg. Most clinics require a 2-hour total appointment time including prep and recovery.

Cost range: $400-$800 per infusion, with most clinics in the $450-$600 range. Major metro areas (New York, San Francisco, Los Angeles) tend toward the higher end. The 6-infusion initial course totals $2,400-$4,800.

Ongoing costs: Most patients need booster infusions to maintain their response, typically monthly, though some patients can space boosters to every 6-8 weeks. At $400-$800 per booster, the annual maintenance cost is $4,800-$9,600. This is where IV ketamine gets expensive: it is not a one-time treatment.

Where the 0.5 mg/kg protocol comes from: A dose of 0.5 mg/kg over about 40 minutes is the protocol used in the NIMH trial by Zarate and colleagues (2006) and the two-site trial by Murrough and colleagues (2013), which is why most depression clinics still start there. Infusions are run by anesthesiologists, CRNAs, emergency physicians or psychiatrists with infusion capability, and that staffing is a large share of what the fee covers. Clinics treating chronic pain, complex regional pain syndrome (CRPS) or fibromyalgia often use longer infusions, so ask whether a pain protocol is priced differently.

IM (Intramuscular) Ketamine: The More Affordable In-Clinic Option

Intramuscular ketamine injections deliver the same medication as IV but through a simple injection rather than an IV line. The clinical experience is similar, you are in a supervised setting, you experience dissociative effects, and you are monitored throughout.

Why it costs less: IM injections do not require IV access, which eliminates the need for IV supplies, nursing time to place the line, and the specialized infusion equipment. The overhead is lower, which gets passed to the patient.

Cost range: $200-$400 per session, with a 6-session course running $1,200-$2,400. Some clinics offer IM as their standard protocol; others offer it as a budget-friendly alternative to IV.

Efficacy: The research on IM ketamine specifically is smaller than IV, but available evidence suggests comparable efficacy. The pharmacokinetics differ slightly, IM absorption is somewhat slower than IV, producing a slightly different experience, but clinical outcomes appear similar for depression.

Who offers it: IM ketamine is common in psychiatric practices and in ketamine-assisted psychotherapy (KAP), where a therapist stays with the patient during the session. When the session includes a therapist, the fee often reflects both the medical monitoring and the therapy hour, so ask what each part costs.

Spravato (Esketamine Nasal Spray): The FDA-Approved Option

Spravato is the brand name for esketamine nasal spray, FDA-approved in 2019 for treatment-resistant depression (and later for MDD with acute suicidal ideation). It is manufactured by Janssen (Johnson & Johnson) and is the only FDA-approved form of ketamine for depression.

How it works practically: Spravato must be administered in a certified healthcare setting under the REMS (Risk Evaluation and Mitigation Strategy) program. You self-administer the nasal spray under supervision, then are monitored for at least 2 hours before you can leave. You cannot take the medication home.

Cost without insurance: $600-$900 per session. The induction phase requires twice-weekly sessions for the first month (8 sessions, ~$4,800-$7,200), followed by weekly or biweekly maintenance. Without insurance, Spravato is the most expensive ketamine option.

Spravato dosing and maintenance schedule

Spravato comes in 28 mg nasal devices, and the FDA prescribing information for Spravato (2019) sets an induction phase of 56 mg on day one, then 56 mg or 84 mg twice a week through week four, weekly dosing in weeks five through eight, and weekly or every-other-week maintenance from week nine. That schedule explains the cost profile: the first month carries eight sessions, and maintenance continues for as long as your psychiatrist judges it useful. Under that original label, Spravato is taken alongside an oral antidepressant.

At-Home Ketamine: Telehealth Programs and Compounding Pharmacies

The at-home ketamine market has grown rapidly, offering oral and sublingual ketamine through telehealth platforms and compounding pharmacies. These programs provide the most affordable access to ketamine but with important trade-offs in supervision and dosing control.

Telehealth Ketamine Services

Telehealth ketamine platforms offer at-home ketamine treatment through a subscription model:

• How it works: You have an initial evaluation with a prescribing provider (usually a psychiatrist or psychiatric NP) via telehealth. If approved, sublingual ketamine tablets or troches are mailed to your home. You self-administer at home with a guide or monitor present, often with virtual check-ins.
• Cost: $200-$400/month, which typically includes the medication, provider consultations, and access to the platform’s support resources. Some charge separately for the initial evaluation ($100-$250).
• Dosing: Sublingual doses are typically lower than IV (100-400 mg sublingual vs. 0.5 mg/kg IV), and bioavailability is lower (about 30% sublingual vs. 100% IV). This means the subjective experience is usually milder, and some patients find at-home ketamine less effective than IV for severe depression.

Compounding Pharmacy Troches

Some psychiatrists prescribe ketamine troches (lozenges) directly, with the medication prepared by a compounding pharmacy:

• How it works: Your psychiatrist writes a prescription for ketamine troches at a specific dose and frequency. A compounding pharmacy prepares and mails the troches. You take them at home on the prescribed schedule.
• Medication cost: $50-$150/month for the troches themselves, depending on dose and quantity.
• Provider cost: You still need a prescribing provider to manage your care, expect $150-$300 for initial evaluation and $100-$200 for follow-up visits (monthly or quarterly). Some of these provider costs may be covered by insurance if billed as psychiatric management.
• Total cost: $100-$350/month when combining medication and provider visits. This is the most affordable ketamine option, but it requires finding a psychiatrist who prescribes ketamine troches, which is not as common as telehealth platforms suggest.

The regulatory picture: Compounded ketamine troches and tablets are not FDA approved for any use. The FDA alert on compounded ketamine products (October 2023) lists abuse and misuse, psychiatric events, raised blood pressure, slowed breathing and bladder symptoms as known risks, and notes that home use removes onsite monitoring. A lower monthly cost buys convenience, not the same level of oversight as a supervised clinic session.

Hidden Costs to Budget For

Regardless of which ketamine format you choose, there are costs beyond the treatment sessions themselves:

• Intake evaluation: $150-$350. Most clinics and providers require an initial psychiatric evaluation before approving ketamine treatment. This may or may not be covered by insurance (it often is, since it is a standard psychiatric visit).
• Lab work: $50-$300. Some providers order baseline labs (liver function, kidney function, blood pressure screening) before starting ketamine. These are usually covered by insurance.
• Transportation: For IV, IM, and Spravato sessions, you cannot drive yourself home. Budget for rideshare, a friend/family driver, or public transit for each session. Over a 6-session course, this adds $50-$200+.
• Time off work: IV and Spravato sessions require 2-3 hours per visit, plus recovery time. Some patients feel fatigued for the rest of the day. For a 6-session initial course, that is 6+ half-days.
• Integration therapy: Many providers recommend psychotherapy sessions alongside ketamine treatment to process the experiences and build on the neuroplastic window ketamine opens. Therapy costs vary ($100-$250/session) and may be partially covered by insurance.
• Monitoring visits: Periodic blood pressure checks, liver function panels, and psychiatric follow-ups add ongoing cost, especially with Spravato’s REMS requirements.

First-Year Cost Comparison

To give a realistic picture of total annual spending, here is what each approach typically costs over the first 12 months (including initial course, boosters, and hidden costs):

Over the first twelve months, compounded troches with a prescriber are the lowest-cost route at an estimated $1,350 to $4,550, IV infusions run $6,800 to $12,800, and Spravato without insurance is the highest at $31,200 to $50,400. With insurance and manufacturer copay assistance, Spravato can fall to an estimated $500 to $5,000 for the year, which is why checking coverage comes first.

Does Insurance Cover Ketamine Therapy?

Insurance covers Spravato more often than any other form of ketamine therapy, usually with prior authorization that documents treatment-resistant depression. IV and IM ketamine for depression are almost always self-pay because they are off label, although some patients submit a superbill for out-of-network reimbursement of the psychiatric evaluation or follow-up visits. Coverage rules change by plan and year, so confirm with your insurer before the intake visit.

Transcranial magnetic stimulation (TMS therapy) is FDA cleared for major depression and is often covered after failed medication trials, which makes it a common insured alternative; TMS and ketamine compared sets out the differences in cost, schedule and side effects. The ketamine therapy insurance breakdown covers prior authorization, appeals and superbills in more depth.

What Conditions Is Ketamine Therapy Used For?

Ketamine therapy is used most often for treatment-resistant depression, where the trial evidence is strongest. Spravato is FDA approved for TRD and for depressive symptoms in adults with major depressive disorder (MDD) with acute suicidal ideation or behavior. Clinics also offer racemic ketamine off label for post-traumatic stress disorder (PTSD), anxiety disorders, bipolar depression, obsessive-compulsive disorder (OCD) and chronic pain conditions such as CRPS and fibromyalgia.

Evidence for those off-label uses is thinner and comes mostly from small trials, and insurers rarely cover ketamine for any of them. The condition also shapes the price, because pain protocols and depression protocols differ in dose, length and number of sessions.

• Depression: ketamine for depression covers how infusions fit alongside antidepressants, psychotherapy, TMS and ECT.
• PTSD and anxiety: ketamine for PTSD and ketamine for anxiety review the smaller trials behind those uses.
• Chronic pain: the chronic pain condition page and the fibromyalgia overview explain where low-dose ketamine fits, and ketamine infusions for chronic pain describes pain protocols in depth.

How to Compare Ketamine Clinics on Price

Comparing ketamine clinics on price works best when every quote covers the same items. Ask each clinic the same six questions before you commit to an initial series:

1. What is the all-in price per infusion or injection, including monitoring and recovery time?
2. What does the intake evaluation cost, and is it billed to insurance as a psychiatric visit?
3. What is the booster price, and does any package discount apply to boosters?
4. Who places the line and monitors the session: an anesthesiologist, a CRNA, an emergency physician, a psychiatrist or a nurse practitioner?
5. Does the clinic coordinate with your psychiatrist or therapist, and does integration therapy cost extra?
6. Will the clinic give you a superbill for out-of-network claims?

The national ketamine therapy clinic directory lists providers by state and city, so you can gather several quotes in one place. Listing order on Regenerated.com is not paid ranking. Featured slots are clearly labeled and capped, Verified means the clinic completed credential checks rather than paying for placement, and the directory is free for patients. Inclusion in the directory is not an endorsement, so put the same questions to every clinic you contact.

Cost-Saving Strategies

If cost is a barrier, and for many people, it is, here are practical strategies to reduce spending:

• Ask about Spravato insurance coverage first. If you have commercial insurance or Medicare Part D, check whether Spravato is on your formulary with prior authorization. Janssen’s copay assistance program can bring your per-session cost to $10. This is often the cheapest path for insured patients.
• Compare IV vs IM pricing. If your clinic offers both, ask about IM injection pricing. The efficacy appears comparable, and you can save 30-50% per session.
• Negotiate package pricing. Many IV ketamine clinics offer discounted rates for prepaid 6-session packages. Ask upfront, some clinics will reduce the per-session rate by $50-$100 when you commit to the full course.
• Use HSA/FSA funds. Ketamine treatment (when prescribed by a licensed provider for a medical condition) qualifies as a medical expense eligible for Health Savings Account (HSA) or Flexible Spending Account (FSA) reimbursement. This effectively gives you a 20-35% discount depending on your tax bracket. IRS Publication 502 sets out which medical care and prescribed drugs count as qualifying expenses.
• Consider at-home protocols for maintenance. Even if you start with IV infusions for the initial course (where evidence is strongest), you may be able to transition to sublingual ketamine at home for ongoing maintenance, significantly reducing long-term costs.
• Ask about clinical trials. Academic medical centers (NIMH, university hospitals) sometimes conduct ketamine research studies that provide treatment at no cost. ClinicalTrials.gov is the best resource for finding active studies.
• Check for sliding-scale clinics. Some ketamine clinics offer reduced rates based on income, or allocate a percentage of appointments to lower-income patients. It is worth asking, though availability varies.

Frequently Asked Questions

How much does a ketamine booster infusion cost?

A ketamine booster infusion costs $400 to $800 at most US clinics, the same range as an infusion in the initial six-session series, while an intramuscular booster costs $200 to $400. Most patients start with roughly one booster a month after the initial course, which adds $4,800 to $9,600 a year for IV maintenance. Ask whether the clinic's package discount extends to boosters, and confirm the booster rate in writing before you start.

Does insurance ever cover IV ketamine?

As of 2026, IV ketamine for depression is almost never covered by insurance, because racemic ketamine is FDA approved only as an anesthetic and its use for depression is off label. A few employer-sponsored plans or out-of-network claims reimburse part of the cost, and the psychiatric intake visit is often covered on its own. If insurance coverage matters most to you, Spravato is the most viable path, since insurers commonly cover it with prior authorization.

Why is Spravato so much more expensive than IV ketamine before insurance?

Spravato costs more before insurance because it is a patented, brand-name drug (esketamine, the S-enantiomer of ketamine), while IV clinics use inexpensive generic racemic ketamine. Each Spravato session also includes the REMS requirement of at least two hours of in-office observation, and the price carries the manufacturer's development and approval costs. With insurance coverage and Janssen's copay assistance, Spravato can become the cheapest option for insured patients, with sessions as low as $10.

Is at-home ketamine as effective as IV infusions?

At-home sublingual ketamine has weaker evidence than IV infusions. Sublingual bioavailability is about 30% compared with 100% for IV, so lower effective doses reach the brain. Some patients respond well at home, while others find it insufficient and eventually pursue IV. At-home protocols tend to suit mild-to-moderate treatment-resistant depression or maintenance after an initial IV course, and the FDA notes that home use removes onsite monitoring.

How many booster infusions will I need long-term?

Most patients need about one booster a month in the first year, though the range runs from biweekly to every two or three months. Some people maintain their improvement for months after the initial six-infusion course, and many can space infusions further apart over time. Your provider adjusts the schedule based on your symptom pattern, so budget conservatively for monthly boosters when planning financially.

What is the cheapest way to get ketamine therapy?

The cheapest way to get ketamine therapy is usually Spravato with insurance and manufacturer copay assistance, which can cost as little as $10 per session. Without insurance, compounded ketamine troches prescribed by a psychiatrist cost $100 to $350 a month including visits, and IM injections at $200 to $400 per session are the lowest-cost supervised in-clinic option. HSA or FSA funds lower the effective price of any of these.
