What is ketamine therapy?

Ketamine therapy uses sub-anesthetic doses of ketamine — administered intravenously under direct clinical supervision — to rapidly reduce symptoms of treatment-resistant depression, PTSD, anxiety, and suicidal ideation.

Unlike traditional antidepressants that target serotonin and can take 4–6 weeks to work, ketamine acts on the brain's glutamate system and can produce meaningful relief within 24–72 hours of the first infusion.

It is one of the most significant breakthroughs in psychiatry in decades — offering hope to the roughly 30% of people with depression who don't respond to conventional treatment.

What ketamine therapy is not

Ketamine therapy is not a standalone cure and works best as part of a comprehensive mental health plan that may include therapy, lifestyle support, and ongoing monitoring by your Hudson Mind clinician.

1

Blocks NMDA receptors

ketamine binds to N-methyl-D-aspartate receptors, reducing glutamate-driven hyperactivity linked to depression and trauma.

2

Triggers BDNF release

stimulates brain-derived neurotrophic factor, promoting new synaptic growth and neural plasticity.

3

Restores neural connectivity

depression literally shrinks synaptic connections. Ketamine helps rebuild these pathways quickly.

4

Creates a window for change

enhanced neuroplasticity post-infusion makes this an ideal time to reinforce gains through therapy.

Complex and chronic PTSD including military trauma, childhood adversity, and assault. Often combined with SGB.

03

Anxiety disorders

Generalized anxiety, social anxiety, and panic disorder that has not responded to standard pharmacotherapy.

04

Suicidal ideation

Ketamine has demonstrated rapid anti-suicidal effects and may be appropriate in acute or crisis situations.

How Hudson Mind treats with ketamine

Our ketamine protocol is grounded in clinical evidence and refined by real-world patient outcomes. Every step is supervised by a board-certified psychiatrist.

01

Free discovery call

A complimentary call with our intake team to walk through the onboarding process, insurance and fees, and a treatment overview—plus any questions you have. It's optional, but most patients find it helpful to get logistical questions answered before meeting with a provider.

02

Comprehensive psychiatric evaluation

Before any treatment begins, you meet with a Hudson Mind provider for a 45-60 minute evaluation covering your history, diagnoses, prior trials, and goals. This informs your personalized treatment plan.

03

IV ketamine infusions (4–6 sessions)

Infusions are administered intravenously over 40–60 minutes in our clinical setting. You remain awake and reclining throughout. Vitals are continuously monitored. The experience is calm and mildly dissociative for most patients.

04

Integration support

The neuroplasticity window following ketamine infusions is a powerful time for therapeutic work. Hudson Mind coordinates with your existing therapist or can refer you to integration-focused therapists who specialize in working alongside ketamine protocols.

05

Ongoing monitoring & maintenance

After your initial course, we evaluate your response and design a maintenance plan. Some patients sustain results for months; others benefit from a booster infusion every 4–8 weeks. We track your progress and adjust your plan accordingly.

06

Spravato® (esketamine) as an alternative

If you prefer an FDA-approved, insurance-covered option, Hudson Mind also offers Spravato® (esketamine nasal spray) for qualifying diagnoses. Our team will help determine which approach is the better fit.

What to expect at your infusion

Here's what a typical ketamine therapy experience looks like at Hudson Mind, from preparation to post-infusion care.

1

Before your infusion

Fast for 4–6 hours before your appointment. Wear comfortable clothing. You'll need a friend or rideshare to take you home — driving after infusions is not permitted. Our team will send you a preparation guide in advance.

2

Arrival & setup

You'll be settled into a comfortable, quiet room. A nurse or clinician places a small IV line and connects monitoring equipment to track your heart rate and blood pressure throughout.

3

The infusion

The infusion runs over 40–60 minutes. You may notice a mild floating or dreamy sensation, altered perception of time, or mild visual effects. These are normal and resolve quickly after the infusion ends. Many patients find the experience peaceful.

4

Recovery & discharge

After the infusion ends, you'll rest in our recovery area for 15–30 minutes while the effects fully clear. Most patients feel grounded and well within an hour. You'll debrief briefly with a clinician before leaving.

5

In the days that follow

Many patients notice mood improvement within 24–72 hours. Some experience it the same day. Your care team will check in following each infusion and after your full course to assess your response and next steps.

Ready to find out if ketamine is right for you?

Our team will walk you through your options, answer your questions, and help you take the next step — with no pressure.

What is ketamine therapy?

Ketamine therapy uses low-dose ketamine administered under medical supervision to rapidly reduce symptoms of treatment-resistant depression, PTSD, anxiety, and suicidal ideation. It works on the brain’s glutamate system rather than serotonin, producing relief within hours to days rather than weeks.

How quickly does ketamine therapy work?

Many patients report significant mood improvement within 24–72 hours after their first infusion — far faster than traditional antidepressants, which typically take 4–6 weeks. Some patients notice improvement the same day.

How many ketamine infusions are typically needed?

A standard initial course consists of 4–6 infusions delivered over 2–3 weeks. Maintenance infusions may be recommended every 4–8 weeks depending on your clinical response and treatment goals.

Is ketamine therapy safe?

When administered by trained clinicians in a controlled medical setting, ketamine therapy has a well-established safety profile with decades of clinical use. Hudson Mind monitors all patients continuously during each session and conducts a thorough medical evaluation before treatment begins.

Does insurance cover ketamine infusions?

IV ketamine infusions are typically not covered by insurance as they are used off-label. However, Spravato® (esketamine), an FDA-approved form of ketamine available at Hudson Mind, is covered by most major insurers for qualifying diagnoses.

What does a ketamine infusion feel like?

Most patients experience a mild dissociative state — a floating or dreamy sensation, altered perception of time, and occasionally mild visual effects. The experience is calm and monitored throughout. All effects resolve within an hour of the infusion ending.

Can ketamine therapy be combined with antidepressants?

Yes. Most patients continue their existing medications during ketamine therapy. In some cases, the combination produces better outcomes. Your Hudson Mind psychiatrist will review your full medication regimen before treatment.
