Ketamine has been used safely in medical settings for more than five decades, yet most patients first encountering it as a psychiatric treatment carry assumptions shaped by its reputation as a recreational substance rather than by its clinical record. IV ketamine therapy — delivered intravenously under continuous medical supervision — is distinct from any other use of the drug in dose, setting, monitoring, and therapeutic intention. At Mend The Mind in Livingston, Montana, we administer every infusion with a Board Certified Registered Nurse Anesthesiologist, bringing the same precision and safety standards used in surgical anesthesia to psychiatric care.
Ketamine’s Medical History
Ketamine was developed in the 1960s and has served as a safe, reliable anesthetic agent in medical settings for decades — used in surgeries, emergency medicine, and pediatric care worldwide. According to Johns Hopkins Bloomberg School of Public Health, researchers and clinicians began observing that patients receiving ketamine for medical procedures sometimes experienced rapid, notable improvements in mood that outlasted the anesthetic effects by days or even weeks. That observation seeded a growing body of psychiatric research that has since produced substantial evidence for ketamine’s effectiveness in conditions that standard treatments often fail to adequately address.
This history matters for patients considering ketamine therapy for the first time. You are not evaluating an experimental compound with an uncertain safety record — you are evaluating a medication with a well-established clinical history, now applied to a psychiatric context with an accumulating evidence base.
At Mend The Mind, we take that history seriously. Our founder Cassidy Boyer is a Board Certified Registered Nurse Anesthesiologist with more than a decade of clinical experience, including her service as a USAF veteran. She is also completing her post-master’s training as a Psychiatric-Mental Health Nurse Practitioner at Montana State University. That combination of anesthesia expertise and advancing psychiatric training defines how we approach every infusion — not as a wellness service, but as a medical procedure administered with precision.
How IV Ketamine Works in the Brain
Understanding why IV ketamine produces psychiatric effects requires a brief look at brain chemistry. Most first-line antidepressants — SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitors), for example — work by increasing the availability of serotonin or norepinephrine, neurotransmitters associated with mood regulation. These medications help many people. For patients whose depression, anxiety, or PTSD has not responded to multiple medication trials, however, a different mechanism may be needed.
Ketamine works primarily by blocking NMDA receptors — N-methyl-D-aspartate receptors, which are proteins in the brain that respond to glutamate, the brain’s primary excitatory neurotransmitter. According to research supported by the National Institutes of Health, this blockade triggers a cascade of neurochemical events that produce rapid antidepressant and anti-anxiety effects through a pathway entirely distinct from serotonin-targeting medications. This is why patients who have tried many antidepressants without meaningful relief can still respond to ketamine — it is not another version of what they have already tried.
Beyond its direct receptor effects, ketamine also promotes neuroplasticity — the brain’s capacity to form new neural connections and adapt its structure in response to experience. Further research from the National Institutes of Health indicates that these neuroplastic changes may help sustain ketamine’s antidepressant effects beyond the immediate treatment window. This is part of why the period following each infusion represents a therapeutically significant time: the brain is in a heightened state of receptivity, and intentional integration — whether through rest, reflection, or somatic practices — can support the consolidation of those changes.
Why Intravenous Administration Specifically
Ketamine can be delivered through several routes: oral troches (dissolvable lozenges), nasal spray, intramuscular injection, and intravenous infusion. Each method differs significantly in how reliably the medication reaches the bloodstream, how precisely the dose can be controlled, and what kind of medical oversight is feasible during treatment.
Intravenous administration delivers ketamine directly into the bloodstream, providing complete bioavailability — meaning the full therapeutic dose reaches the system without being reduced by digestive processes or variable absorption rates. IV delivery also allows for real-time dose adjustment during a session, if your response indicates that a change would be beneficial. Continuous vital sign monitoring throughout the infusion — heart rate, blood pressure, and oxygen levels — adds a layer of medical safety that other delivery methods cannot replicate.
For patients whose conditions are complex or severe, or who have not responded to multiple treatments, these precision and safety advantages are clinically meaningful. That is the standard we hold at Mend The Mind — not because it is required by regulation, but because it reflects what responsible administration of a dissociative medication actually demands.
We also offer ketamine troches — dissolvable lozenges prescribed for at-home use — as a maintenance option between IV sessions or as a standalone treatment for patients who have established a therapeutic ketamine response and need flexible ongoing support. The appropriate format depends on your clinical history, your goals, and what your evaluation reveals about your specific needs. Both options are discussed thoroughly before any recommendations are made.
The Treatment Protocol at Mend The Mind
Our standard initial protocol for IV ketamine therapy consists of six infusions scheduled over two to three weeks. Most patients receive two sessions per week during this induction phase, though we adjust scheduling to individual circumstances when needed.
Before your first infusion, we conduct a comprehensive evaluation covering your medical and psychiatric history, current medications, and treatment goals. This evaluation determines whether IV ketamine therapy is appropriate for your specific situation — not every patient is a candidate, and we are straightforward about that.
On treatment days, you arrive at our Livingston clinic and settle into a private, comfortable treatment room. An IV line is placed, and continuous monitoring begins. Mental health infusions typically last 40 to 60 minutes; chronic pain protocols may run longer depending on your condition. Most patients use an eye mask and headphones during the session — we have music available — and many describe the experience as deeply relaxing or characterized by a shift in their usual thought patterns. You remain conscious and able to communicate throughout, and we are present with you at all times.
Following your infusion, you rest in recovery while we continue monitoring your vital signs. Most patients feel ready to leave within 15 to 30 minutes after the infusion ends. A safe ride home is required for every session without exception — you cannot drive yourself. We encourage patients to protect the 24 to 48 hours following treatment as integration time: avoiding high-stress demands and creating space to notice what has shifted.
After the initial six-session series, we evaluate your response and discuss whether maintenance booster infusions are appropriate for sustaining your progress. Booster frequency varies considerably between patients — some find monthly sessions sufficient, while others benefit from more frequent maintenance.
Discussing Cost and Insurance Honestly
One of the most common questions patients ask is about cost, and we believe in discussing it directly. Pricing for IV ketamine therapy at Mend The Mind is available upon consultation rather than published on our website, because treatment plans vary and we want every patient to have an accurate picture of their specific situation before committing to anything.
Regarding insurance: we are an out-of-network provider. Through the Osmind care management platform we use with every patient, you receive a detailed superbill following each session that can be submitted to your insurance company for potential reimbursement. We do not process insurance claims on your behalf, but we make sure you have everything required to pursue reimbursement through your plan. Coverage outcomes vary significantly by insurance plan, and we recommend contacting your insurer before starting treatment to understand your out-of-network benefits.
We will not pretend that cost is not a real consideration — it is, and we know that for some patients it is the deciding factor. We are committed to transparent conversations about the financial side of treatment early in the process, so cost is never a surprise.
Addressing Fear and Stigma
A second barrier we hear regularly from patients is apprehension — about what ketamine feels like during an infusion, whether the altered perception is frightening, and whether choosing ketamine therapy carries stigma. These concerns deserve a direct answer.
The experience during an IV ketamine infusion is not what most people expect based on cultural associations with the substance. At therapeutic doses in a clinical setting, most patients describe sensations of deep relaxation, detachment from their usual thought patterns, emotional openness, or a quiet and expansive mental state. The experience varies between individuals and between sessions for the same person. Research from the National Institutes of Health confirms that side effects from a single antidepressant-dose IV ketamine infusion are generally mild and brief, resolving as the medication clears the system.
Choosing ketamine therapy after multiple unsuccessful treatments is not a sign of failure — it is a clinically informed decision to try a different mechanism when previous mechanisms have not produced adequate relief. We see patients regularly who have tried everything their primary care provider and their previous psychiatrists offered. Their persistence in seeking effective care is not a character flaw; it is exactly the kind of history that warrants a careful evaluation.
Frequently Asked Questions
What conditions does IV ketamine therapy treat at Mend The Mind?
We offer IV ketamine therapy for treatment-resistant depression, PTSD, anxiety, OCD, suicidal ideation, bipolar disorder, and chronic pain conditions including fibromyalgia, neuropathic pain, and restless legs syndrome. Each patient is evaluated individually, and candidacy is determined based on your full clinical history — condition alone does not determine whether treatment is appropriate.
How long until I notice results from IV ketamine therapy?
Many patients notice changes within hours to days of their first infusion — a significantly faster onset than traditional antidepressants, which typically require weeks to show effect. Results vary by individual. Some patients require three to four sessions before experiencing meaningful relief, and the clearest therapeutic picture often emerges across the full initial six-session series.
Do I need to stop my current medications before starting?
This depends on your specific medications and clinical situation. We review all current medications during your evaluation and will discuss any adjustments needed before or during treatment. Do not stop or change any medications without guidance from your prescribing provider.
