Ketamine Therapy Clinics in New Hampshire

Clinics in New Hampshire work with patients dealing with treatment-resistant depression, PTSD, OCD, anxiety disorders, and certain chronic pain conditions that have not improved with conventional approaches. The therapy is not a guaranteed fix for any of these, and the right fit depends on your individual history.

A licensed medical provider at the clinic will evaluate whether ketamine therapy makes sense for your situation before treatment starts.

IV ketamine is delivered through an intravenous line over a monitored session, typically at a clinic staffed by anesthesiologists or other trained providers. It is used off-label for mental health and pain conditions.

Spravato is an FDA-approved nasal spray form of esketamine, administered in a certified clinical setting where you are observed for a period after each dose. The two are different compounds, given in different ways, and the choice between them depends on your diagnosis, prior treatment history, and what your provider recommends.

You arrive at the clinic, check in, and a staff member reviews your vitals before the session begins. Depending on the format, you may receive an IV infusion, a nasal spray dose, or another method in a supervised room.

Sessions usually last between 45 minutes and two hours. Afterward, you are monitored briefly and should arrange a ride home, since driving after treatment is not advised.

The largest concentration of clinics is in and around Manchester, Nashua, Londonderry, Exeter, and the Seacoast communities near Portsmouth. There are also clinics in Concord, Conway, Keene, Lebanon, Plymouth, and several smaller towns. The city list on this page shows where options exist across the state.

Coverage depends heavily on which treatment type you receive and what insurance plan you carry. IV ketamine is generally not covered and is paid out of pocket.

Spravato has a better chance of insurance reimbursement because it is FDA-approved, but whether your specific plan covers it, and how much, requires a call to your insurer. Most clinics can help you check benefits before your first appointment.

A number of New Hampshire clinics publish per-infusion pricing, though many still do not list rates online. The total cost for a starter course depends on which treatment format you choose and how many sessions are included. Calling clinics directly is often the fastest way to get accurate, current figures for your situation.

This directory only lists clinics that administer ketamine in person on site. At-home or telehealth ketamine is not covered here, and the listings you see reflect facilities where you attend treatment in a clinical setting.

Start by confirming that the clinic offers the specific treatment format your provider recommends. Then look at who will be supervising your care, what the intake process looks like, and how the clinic handles follow-up.

Pricing transparency matters too. Some New Hampshire clinics post rates clearly, so ask for a full cost breakdown before committing.

Yes. Ketamine is a Schedule III controlled substance under U.S. federal law and is legal for licensed clinicians to prescribe and administer off-label, including for treatment-resistant depression and other conditions.

Spravato (esketamine), the FDA-approved nasal-spray form, is dispensed only in certified healthcare settings under a federal Risk Evaluation and Mitigation Strategy (REMS) program. That applies in New Hampshire as it does nationwide.

The standards for who may administer treatment are set by state regulators and by the clinicians themselves; you can look up the current licensing board for your state through the Federation of State Medical Boards directory at fsmb.org.
