Ketamine Therapy Clinics in New Hampshire

Most clinics in the state see patients dealing with treatment-resistant depression, PTSD, OCD, anxiety disorders, and certain chronic pain conditions. These are situations where earlier treatments did not produce enough relief. A licensed provider at the clinic will review your history to determine whether ketamine therapy is appropriate for you.

IV ketamine is given through an intravenous line and is used off-label, meaning it is not FDA-approved specifically for depression but has a substantial clinical track record. Spravato is an FDA-approved nasal spray form of esketamine, administered in a clinic setting with a monitoring period afterward. The two have different dosing protocols, costs, and insurance implications, so it is worth discussing both options with the prescribing provider.

The highest concentration of clinics is in the southern part of the state. Bedford, Manchester, Nashua, Londonderry, and Concord account for most of the listings. Spravato in particular is offered across a wider range of towns, from Portsmouth and Dover on the Seacoast to smaller communities like Hooksett and Merrimack.

Most clinics start with an intake evaluation to review your medical and mental health history before scheduling any treatment. During an IV session, you are in a monitored chair or recliner for roughly forty minutes to an hour while a clinician tracks your blood pressure, heart rate, and overall response. Spravato visits follow a similar structure, with a required observation period after the nasal spray is administered. You will need a ride home after either type of session.

Several clinics in the state post their per-session pricing, which gives you a useful starting point. The total cost depends on the format you receive and the number of sessions in your starter course. Self-pay is common across most formats. Spravato is the treatment most likely to be covered by insurance, though coverage depends entirely on your specific plan and diagnosis.

For most IV ketamine infusions, patients pay out of pocket because the treatment is used off-label. Spravato has a clearer path to insurance coverage since it carries FDA approval, but whether a given plan actually covers it depends on the insurer, the diagnosis, and prior authorization requirements. It is worth calling your insurance company directly before scheduling.

Yes, particularly for Spravato. Clinics offering that format are listed in towns across the Seacoast and southern New Hampshire, not only the larger cities. IV ketamine has a smaller footprint and is more concentrated in places like Concord, Londonderry, Nashua, and a few Seacoast communities.

No. Every listing in this directory is a clinic that administers treatment on site. If a provider you contact offers a remote-only service, they fall outside the scope of this directory.

Start with which treatment format you want, since not all three cities offer the same options. Then compare the intake process, the credentials of the supervising clinicians, and published pricing. A brief phone call to two or three clinics can quickly clarify differences that are hard to see from a website alone.

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.
