The cost of IV ketamine in NYC and Long Island typically ranges from $400 to $900 per infusion, with a standard six-infusion series totaling about $2,400 to $5,400. This price varies depending on who administers the treatment, the level of monitoring, and the extent of psychiatric care included.

IV ketamine therapy is the controlled, intravenous delivery of a low-dose ketamine solution in a medical setting. Unlike traditional antidepressants that can take four to eight weeks to work, ketamine targets different neurotransmitter pathways in the brain, promoting new neural connections and often producing noticeable shifts in mood within hours to days.
Â
Â
Across the New York metro area, per-infusion pricing typically lands in the $400 to $900 range:
Lower end: shorter sessions, minimal monitoring, or nurse-led administration
Higher end: physician-administered infusions, longer observation, and psychiatric oversight of the full treatment plan
Chronic pain protocols: often longer than the standard 40- to 60-minute mood-disorder infusion, which raises the per-session fee
Â
The price reflects not just the medication, but the entire clinical service – provider time, monitoring equipment, and facility overhead.
Â
Ketamine is rarely a one-visit treatment. A typical induction series is six infusions over two to three weeks, putting the initial course somewhere between roughly $2,400 and $5,400.
Â
After induction, many patients move to maintenance infusions – sometimes every two to six weeks, sometimes less often. The more useful question isn’t the per-session price, but what the first year looks like: induction plus an individualized maintenance schedule.
Â
Factor in the diagnostic evaluation as well. A comprehensive 60-minute psychiatric evaluation is conducted by Dr. Alfredo Nudman and is paid separately. Patients coming specifically for IV ketamine receive a complimentary 15-minute consultation first.
Â
Alfredo Nudman Medical PC offers several innovative treatments, and costs differ by mode of administration and protocol:
IV ketamine infusions: Considered the gold standard by many for their 100% bioavailability and precise, real-time dose titration. It costs more per session than IM because it requires IV access and continuous monitoring.
IM ketamine: Often priced lower, commonly in the $300 to $500 range, but the dose cannot be modified once injected.
SPRAVATO® (esketamine): An FDA-approved nasal spray for treatment-resistant depression, administered in a certified clinic. It’s the one option many insurance plans will cover, though our practice does not participate with insurance, so patients pursue out-of-network reimbursement themselves. SPRAVATO also requires two hours of in-office monitoring after each dose, twice weekly at the start – a real-time cost even when the dollar cost is lower.
Nitrous oxide therapy: Also offered for depression and anxiety, typically priced below IV infusions per session.
Â
Â
A quoted infusion price at a physician-led practice like Dr. Alfredo Nudman’s generally covers:
The ketamine medication and IV supplies
A private, comfortable room for your session
Continuous vital sign monitoring throughout the infusion
Direct clinical supervision by Dr. Alfredo Nudman during the infusion and recovery period
Brief check-ins to assess your response and adjust dosing for the next session
Â
Initial psychiatric evaluation. The 60-minute comprehensive workup is a separate fee and the foundation of a safe plan.
Medication management follow-ups. Periodic visits to monitor progress and adjust psychopharmacology.
Transportation. You cannot drive yourself home after an infusion.
Maintenance. Plan for it rather than being surprised by it.
Â
Several variables explain the wide range:
Who administers and supervises. A psychiatrist managing your full treatment plan is a different service than a technician starting a drip. Dr. Alfredo Nudman’s 35 years of diagnostic and psychopharmacological expertise are integral to safety and effectiveness.
Session length and dose. Pain protocols and higher doses take longer.
Depth of psychiatric integration. Programs coordinating diagnosis, medication, and infusions cost more to run.
Location. Overhead is higher in some areas than others – one reason many tristate-area patients travel to Long Island for treatment.
Bundling. Some practices price per infusion; others price a full series.
Â
So, how much does IV ketamine cost in NYC and Long Island? Expect roughly $400 to $900 per infusion and $2,400 to $5,400 for an initial six-session series, plus a diagnostic evaluation and ongoing maintenance. Because insurance rarely covers infusions, clarity matters more than a low headline price – and the cost reflects a comprehensive service delivered by a highly qualified expert, not just a medication.
