Ketamine Infusion Therapy on Long Island: A Modern Approach
Call (516) 246-9588
Zen Integrative Care provides both psychiatric services and ketamine treatment. Ketamine is not appropriate for everyone — every patient is individually evaluated. We do not accept Medicaid or Medicaid managed-care plans.
For many individuals throughout Nassau and Suffolk Counties, traditional mental health treatments have often fallen short of providing lasting relief. Chronic depression, treatment-resistant anxiety, and complex PTSD can create a cycle of hopelessness that standard oral medications struggle to break. ketamine infusion therapy at Zen Integrative Care on Long Island offers a paradigm shift in psychiatric care, providing a biological intervention for those who have not found success with SSRIs, SNRIs, or conventional talk therapy alone.
The clinical application of ketamine has transitioned from a specialized alternative to a foundational tool in interventional psychiatry. Our Long Island clinic provides a controlled, medically supervised environment where patients can access intravenous (IV) ketamine infusions. This therapy is designed to address the physiological root causes of mood disorders, offering a path forward for patients seeking to regain their quality of life and emotional stability.
At our facility, we recognize that every patient carries a unique history. Ketamine therapy is not a one-size-fits-all solution; it is a personalized medical procedure. By integrating ketamine infusion therapy at Zen Integrative Care into a comprehensive wellness plan, we help residents across the island bridge the gap between persistent symptoms and functional recovery. Our commitment is to provide a compassionate, evidence-based experience that prioritizes patient safety and long-term mental health outcomes.
How It Works
The mechanism behind ketamine infusion therapy differs significantly from traditional antidepressants. While most conventional medications target monoamines like serotonin, norepinephrine, or dopamine, ketamine acts on the glutamate system. Glutamate is the most abundant neurotransmitter in the brain and plays a critical role in how the brain processes information and regulates mood. Specifically, ketamine acts as an antagonist to the N-methyl-D-aspartate (NMDA) receptors. By blocking these receptors, ketamine triggers a cascade of biological events that result in the release of other molecules, such as brain-derived neurotrophic factor (BDNF).
BDNF is often described as “brain fertilizer” because it supports the health of existing neurons and encourages the growth of new synaptic connections. Over time, chronic stress and depression can cause the connections between neurons—synapses—to wither or shrink, a process known as synaptic pruning. ketamine infusion therapy at Zen Integrative Care on Long Island potentially helps reverse this damage by promoting neuroplasticity. This allows the brain to “rewire” itself, creating more resilient pathways that can better handle stress and emotional regulation.
The intravenous (IV) protocol is considered the gold standard for ketamine delivery because it allows for 100% bioavailability. IV administration is widely used because it allows precise, individualized dosing and continuous adjustment throughout treatment. This means the medication enters the bloodstream directly and is delivered to the brain in a precise, controlled manner. During an infusion, the dosage is carefully titrated to your specific body weight and clinical response. This level of precision ensures that the brain receives the optimal concentration of the medication necessary to stimulate neuroplasticity while minimizing the risk of adverse reactions or discomfort.
Who Is This Treatment For?
Ketamine infusion therapy is primarily indicated for individuals who have tried multiple standard treatments without significant improvement. This is often referred to as treatment-resistance. Because ketamine works through a unique biological pathway, it can be effective even when other medications have failed. Our ketamine infusion therapy at Zen Integrative Care program is specifically designed for those seeking a more robust intervention for severe mood and pain-related conditions.
- Individuals with Treatment-Resistant Depression (TRD): Patients who have not achieved remission after trying two or more antidepressant medications.
- Patients with Major Depressive Disorder and Suicidal Ideation: Those requiring rapid stabilization and a decrease in acute depressive symptoms.
- Individuals Struggling with Complex PTSD: Patients who experience intrusive thoughts, hypervigilance, and emotional numbing that have not responded to trauma-informed therapy alone.
- People Living with Generalized Anxiety Disorder: Those who suffer from chronic, debilitating worry and physical symptoms of anxiety that interfere with daily functioning.
- Adults with Severe Postpartum Depression: Mothers experiencing severe mood symptoms that have not responded to first-line treatment.
What the Research Says
Over the past two decades, extensive clinical research has the use of ketamine for mental health. Institutions such as the Yale School of Medicine and the National Institute of Mental Health (NIMH) have conducted landmark studies demonstrating the rapid antidepressant effects of ketamine. Unlike traditional medications that may take weeks or months to show efficacy, research suggests that sub-anesthetic doses of ketamine can produce improvements in mood within hours or days of the initial infusion. These findings have revolutionized the field of psychiatry, moving it toward a more biological understanding of mood disorders.
Further evidence from established research centers, including Johns Hopkins, has highlighted the role of ketamine in fostering neuroplasticity and cognitive flexibility. Clinical trials have shown that ketamine can effectively “reset” certain brain networks that become overactive during depression and anxiety. While ketamine infusion therapy at Zen Integrative Care is not considered a permanent cure, the evidence-based protocol of a “loading phase” followed by maintenance infusions has been shown to sustain relief for significant periods, offering a manageable long-term strategy for those with chronic conditions.
What to Expect at Our Clinic
Your journey begins with a comprehensive medical and psychological screening at our Long Island location. During this initial consultation, we review your medical history, current medications, and treatment goals to ensure that you are a safe candidate for IV therapy. We serve patients from across Nassau and Suffolk Counties, providing a convenient and professional setting for your care. Once cleared for treatment, we will develop a personalized dosing schedule, typically involving a series of six stabilization infusions over a two-to-three-week period.
During the session, you will be in a private, comfortable room equipped with advanced monitoring technology. A medical professional will start a small IV and begin the infusion, which usually lasts about 40 minutes. You may experience a “dissociative” feeling, where you feel detached from your surroundings or body; many patients find this deeply relaxing or introspective. After the infusion, there is a 20-to-30-minute recovery period where we monitor your vitals until you are ready to be discharged to a pre-arranged driver. We also emphasize the importance of integration, encouraging you to work with your therapist following sessions to capitalize on the period of enhanced neuroplasticity.

Safety, Screening, and Side Effects
Patient safety is our highest priority throughout the ketamine infusion therapy at Zen Integrative Care process. Every patient undergoes an extensive screening process to rule out contraindications such as uncontrolled hypertension, active psychosis, or certain cardiovascular conditions. By maintaining a strictly controlled medical environment, we ensure that the sub-anesthetic doses used are safe and well-tolerated. Most side effects are transient, meaning they occur only during the infusion or shortly after, and resolve on their own within an hour or two.
- MILD DISSOCIATION: A feeling of being “light” or detached from the body.
- ELEVATED BLOOD PRESSURE: A temporary, modest increase in heart rate and blood pressure during the infusion.
- NAUSEA: Some patients may feel slight stomach upset, which can be managed with anti-nausea medication.
- DIZZINESS: A feeling of lightheadedness immediately following the session.
- FATIGUE: Some patients feel drowsy for the remainder of the day and choose to rest after their appointment.
Our medical team remains bedside or nearby for the duration of every treatment. We monitor cardiovascular and respiratory function throughout the procedure to ensure immediate response to any fluctuations. Because the half-life of ketamine is very short, side effects dissipate quickly as the medication leaves the system. Following your session, you will not be permitted to drive or operate heavy machinery for 24 hours, ensuring you have ample time to fully return to your baseline state.
Insurance, Cost, and Next Steps
Navigating the financial aspects of advanced mental health care can be complex. Currently, most private insurance carriers do not provide full coverage for ketamine infusion therapy at Zen Integrative Care as it is often considered an “off-label” use for depression. However, for patients prescribed Spravato (esketamine nasal spray), we work with many in-network plans to maximize your benefits. For IV ketamine infusions, we offer transparent self-pay pricing and provide “superbills” that you may submit to your insurance company for potential out-of-network reimbursement.
To help make this potentially life-changing treatment more accessible, we partner with financing services like CareCredit, which allow for flexible monthly payment plans. Our team is dedicated to helping you understand the costs upfront so there are no surprises. The first step is to contact us for a free initial phone consultation. During this call, we can discuss your specific needs, verify your insurance for Spravato if applicable, and explain our IV infusion packages. We are here to guide you through every step of the process, from the first inquiry to your final maintenance session.
What to Bring & How to Prepare
Patients do not need to bring anything to a ketamine session — our office provides noise-canceling headphones, an eye mask, a blanket, and a curated playlist designed for the experience. You are welcome to bring your own music if you prefer. Please follow these pre-treatment instructions:
- No solid food for at least 4 hours before your appointment.
- No liquids for at least 1–2 hours before your appointment.
- Wear comfortable, loose-fitting clothing.
- Arrange a designated driver for the trip home — you cannot drive yourself for 24 hours after a session.
Frequently Asked Questions
Is ketamine infusion therapy safe?
Yes, when administered by trained medical professionals in a clinical setting, ketamine infusion therapy is very safe. We use sub-anesthetic doses that are significantly lower than those used in surgical settings, and we continuously monitor oxygen saturation, blood pressure, heart rate, and heart rhythm throughout the entire process.
How many infusions will I need?
Most clinical protocols suggest a “loading phase” of six infusions over the course of two to three weeks to achieve initial stabilization. Following this phase, many patients transition to a maintenance schedule, receiving a single “booster” infusion every few weeks or months as needed.
What does the infusion feel like?
During ketamine infusion therapy at Zen Integrative Care, most patients describe a feeling of deep relaxation or a “dream-like” state. You may experience mild changes in your perception of light or sound, but you remain awake and aware of your surroundings throughout the session.
Do I need a referral from my psychiatrist?
While a formal referral is not always required for a consultation, we strongly prefer to collaborate with your existing mental health providers. Coordinating care with your primary psychiatrist or therapist ensures that ketamine therapy is integrated effectively into your overall treatment plan.
Can I drive myself home after the treatment?
No, you are not allowed to drive a vehicle or operate machinery for the remainder of the day after an infusion. You must arrange for a responsible adult to drive you home or use a ride-sharing service, and we require confirmation of your transportation before the session begins.
How long do the effects of ketamine last?
The duration of relief varies from person to person; some patients experience improvements for weeks, while others require more frequent maintenance. By following the recommended loading dose and engaging in integration therapy, you can maximize the longevity of the results.
