Introduction

Ketamine-Assisted Psychotherapy (KAP) is an evidence-informed treatment approach that may help reduce depressive symptoms for some people by supporting neuroplasticity and psychological flexibility. Ketamine and esketamine have also been studied as rapid-acting antidepressant options, particularly for treatment-resistant depression (TRD). For people who have tried medication, meditation, lifestyle changes, or even years of talk therapy without lasting relief, KAP can open a therapeutic window where change becomes possible.

Below is a comprehensive, research-backed guide to KAP for depression; written to support patients, therapists, and clinicians seeking safe, responsible, and evidence-based information.

Key Takeaways
KAP combines medication and therapy to support depression symptom change by temporarily increasing the brain’s ability to form new patterns, while the therapist helps translate that window into real-life progress
Treatment follows a clear clinical rhythm — preparation, dosing with monitoring and support, and integration after each session to support lasting emotional and behavioral change.
KAP can be considered for clinically significant depression and treatment-resistant depression (TRD) - Eligibility is individualized and determined through a thorough clinician-led medical and psychiatric intake.
Depression symptoms can shift rapidly or gradually, often evolving from reduced emotional heaviness and hopelessness toward improved motivation, emotional access, and engagement in therapy over time.
Patients frequently describe more 'mental space' from depression, reduced emotional stuckness, and a greater ability to work through underlying patterns in therapy when the treatment is a good fit.

What is Ketamine-assisted psychotherapy (KAP)?

Ketamine-assisted psychotherapy (KAP) for depression and treatment-resistant depression is a treatment model that combines medically supervised ketamine with structured psychotherapy sessions. The medication temporarily increases neuroplasticity - your brain’s ability to form new patterns - while therapy helps patients process anxiety, reframe fear responses, and build healthier emotional regulation strategies

Why Consider KAP for Depression?

Depression is both common and profoundly debilitating. In the United States, the National Institute of Mental Health estimates that 21.0 million adults experienced at least one major depressive episode in 2021—about 8.3% of the adult population. On a global scale, the burden extends into the workforce: the Centers for Disease Control and Prevention reports that depression and anxiety together account for an estimated 12 billion lost working days each year, costing approximately $1 trillion annually in lost productivity.

While many people benefit from psychotherapy, antidepressant medications, lifestyle changes, and social support, a significant portion continue to experience symptoms such as:

  • Persistent low mood or emotional numbness
  • Loss of interest or pleasure (anhedonia)
  • Hopelessness or self-criticism
  • Low energy and fatigue
  • Sleep and appetite changes
  • Difficulty concentrating
  • Social withdrawal and reduced functioning

Traditional treatments can be life-changing, but they may not work for everyone—or may not create enough momentum for sustained recovery. KAP is one option some patients explore when they feel “stuck,” when symptoms remain significant, or when they want a model that integrates biological and psychological change.

KAP is designed to work on two levels:

  • Biological:  Ketamine exerts its rapid antidepressant effects by modulating glutamate signaling through NMDA receptor antagonism, which in turn enhances synaptic neuroplasticity, a series of mechanisms that differ from conventional antidepressants and may explain its effects in patients whose depression has not responded to standard treatments. *
  • Psychological: Psychotherapy can help patients use the treatment window to process emotions, revise patterns, and translate insights into behavior and life changes.

For many patients, KAP can create a sense of 'internal spaciousness' where emotional heaviness lifts, numbness gives way to feeling, and the mind becomes more open to new perspectives. This can make therapy more effective, insight more accessible, and meaningful change more sustainable.

* In adult stress-based animal models of depression, a single subanesthetic dose of ketamine rapidly increases dendritic spine density in the medial prefrontal cortex within 12–24 hours via activity-dependent spinogenesis (rather than reduced pruning), with newly formed, functionally relevant spines persisting for days to weeks and paralleling antidepressant behavioral effects (Duman & Aghajanian, 2012; Liston et al., 2014).


How KAP Works for Depression (The Science Explained Simply)

Depression is maintained by predictable patterns in the brain: blunted reward circuits, rigid negative thought loops, reduced synaptic connectivity, and dampened emotional responsiveness. KAP can interrupt these patterns and may allow new ones to form. Here's how:

#1 Ketamine increases neuroplasticity

Ketamine antagonizes NMDA receptors and induces a transient hyperglutamatergic state, leading to increased AMPA receptor signaling and downstream molecular cascades. These processes are associated with increased BDNF expression and synaptogenesis — the formation of new connections between neurons — supporting enhanced neuroplasticity and the restoration of stress-related synaptic deficits.

In simple terms, ketamine appears to create a temporary state of increased neural flexibility. It does this by briefly boosting communication between brain cells and activating natural repair processes that support learning, emotional recovery, and resilience. Research: https://pmc.ncbi.nlm.nih.gov/articles/PMC12294355/

#2 Negative thought patterns loosen

Depression is often experienced as being trapped — in low mood, in self-critical narratives, in a sense that nothing will change. The 2025 Sakopoulos & Todman review found that integrating psychotherapy with ketamine appeared to enhance cognitive flexibility and therapeutic engagement beyond what ketamine alone produced. The neuroplastic window ketamine opens may make it easier for patients to examine long-held negative beliefs with more distance and openness. 

Research: https://pmc.ncbi.nlm.nih.gov/articles/PMC12294355/

#3 The altered state created by ketamine can be therapeutically meaningful

Ketamine produces short-term dissociative effects - altered perceptions of self, time, and environment. In standard ketamine infusion settings, these experiences are often managed or simply waited out. In KAP, they are worked with.

A 2020 perspective published in Nature Communications (Ballard & Zarate) found that the literature does not support the conclusion that dissociation is necessary for ketamine's antidepressant effects -  but the relationship between the altered state and therapeutic outcomes remains an active area of study. 

Research: https://www.nature.com/articles/s41467-020-20190-4

What KAP adds is preparation and integration: patients arrive knowing what to expect, and they return to process what arose. Meaningful experiences that occur during dosing - such as shifts in perspective, emotional releases, moments of insight -  become material for the therapeutic work. This is a fundamental difference between KAP and ketamine infusion clinics where little or no therapeutic support is provided.

#4 Emotional regulation improves

Many people with depression experience a blunting or numbing of emotion, alongside periods of overwhelm. KAP may temporarily recalibrate the stress response system — reducing hyperarousal and restoring some capacity for emotional range. By creating greater internal safety, some patients find they can access emotions, reflect on their experiences, and engage more fully in therapy.

#5 Psychotherapy becomes more effective

The 2026 Psychopharmacology systematic review identified a key clinical opportunity: ketamine appears to temporarily increase psychological openness and flexibility;  the ability to relate to thoughts and emotions with less reactivity. In this state, many patients find it easier to:

  • Examine depressive beliefs with more perspective
  • Connect present-day mood patterns with underlying emotional experiences
  • Reconsider entrenched narratives about themselves and their future
  • Integrate meaningful insights from dosing sessions into everyday life

This is why ketamine-assisted psychotherapy is not ketamine alone. The psychotherapy component helps translate neurobiological shifts into lasting behavioral and emotional change.

What the Research Shows About KAP for Depression

Depression is where ketamine's evidence base is the strongest. Across randomized controlled trials, real-world clinical data, and multiple systematic reviews - including 19 studies covering more than 1,000 patients - ketamine-assisted psychotherapy has demonstrated rapid, clinically meaningful reductions in depressive symptoms, including in patients who have not responded to conventional treatments.

Ketamine reduces depression symptoms rapidly - within hours, not weeks 

Research: https://pubmed.ncbi.nlm.nih.gov/30917760/

One of the most clinically significant aspects of ketamine is its speed. Traditional antidepressants such as SSRIs and SNRIs typically take weeks to months to produce effects. A 2022 review published in Discover Mental Health (Yavi et al.) found that a single subanesthetic-dose ketamine infusion can rapidly improve depressive symptoms within one day, with antidepressant effects lasting three to seven days. Research: https://link.springer.com/article/10.1007/s44192-022-00012-3

This matters clinically. For people in acute distress — or those who have waited months for conventional treatments to work — the speed of ketamine's effects can be a meaningful intervention in its own right.

Ketamine is effective for Treatment-Resistant Depression (TRD) 

Research: https://link.springer.com/article/10.1007/s40501-025-00346-z

A 2025 systematic review published in Current Treatment Options in Psychiatry analyzed eight studies including 421 participants with treatment-resistant depression - defined as minimal improvement after two or more antidepressant trials. Across all studies, KAP was associated with significant reductions in depressive symptoms. Preliminary evidence also indicated improvements in comorbid conditions including anxiety and chronic pain, reflecting the reality that depression rarely travels alone.

Ketamine can work for the depressive component of bipolar depression, not only MDD 

Research: https://link.springer.com/article/10.1007/s44192-022-00012-3

Standard antidepressants can carry risks for people with bipolar disorder, including the potential to trigger manic episodes. Ketamine offers a different mechanism that is less likely to lead to mania. The Yavi et al. (2022) review found that a single subanesthetic ketamine infusion rapidly improved depressive symptoms in individuals with both major depressive disorder and bipolar depression — a population historically underserved by conventional pharmacology for the depressive component of the disease.

KAP shows promise for sustained symptom relief up to six months 

Research: https://link.springer.com/article/10.1007/s00213-026-07003-0

A 2026 systematic review published in Psychopharmacology (Simpson & Juruena) analyzed 11 studies on KAP for treatment-resistant depression and found that symptom reductions were observed across all included studies, with some improvements sustained up to six months. The review identified two clusters of effective approaches: structured protocol-based interventions and individualized, experiential models — both producing meaningful outcomes.

Relapse is a real challenge -  and psychotherapy is the primary answer to it 

Research: https://www.cambridge.org/core/services/aop-cambridge-core/content/view/97614770DE6BC7846763FE19801D412D/S2056472423000534a.pdf/ketamine_and_psychotherapy_for_the_treatment_of_psychiatric_disorders_systematic_review.pdf

One of the most important findings in the ketamine literature is the relapse problem. Without psychotherapy, ketamine's effects are often short-lived. A 2023 systematic review published in BJPsych Open (Kew et al.) reported that without ongoing therapeutic support, most patients experience a return of depressive symptoms within days of a single dose, and one study found a median time to relapse of just 18 days following a full course of up to six ketamine infusions.

This is precisely why the KAP model exists. Ketamine opens a neurobiological window of increased flexibility and openness. Psychotherapy is what determines how much of that window gets used - and whether the gains last.

More therapy, not more ketamine, is what drives durability 

Research: https://pmc.ncbi.nlm.nih.gov/articles/PMC12294355/

A 2025 retrospective chart review (Sakopoulos & Todman) examined patients with TRD who received ketamine infusions with or without concurrent weekly psychotherapy. All groups showed significant symptom reduction — but the most pronounced effects were seen in those who received ketamine alongside psychotherapy. Critically, the number of infusions did not significantly alter outcomes. What mattered was the integration of therapy, not the quantity of ketamine.

Ketamine + therapy shows enhanced durability across 1,006 patients 

Research: https://www.cambridge.org/core/services/aop-cambridge-core/content/view/97614770DE6BC7846763FE19801D412D/S2056472423000534a.pdf/ketamine_and_psychotherapy_for_the_treatment_of_psychiatric_disorders_systematic_review.pdf

The 2023 Kew et al. systematic review identified 19 studies evaluating 1,006 patients combining ketamine and psychotherapy for psychiatric disorders. Outcomes were largely positive for the addition of psychotherapy to ketamine treatment across depression, PTSD, and substance use disorders — representing one of the largest combined evidence bases in the KAP literature to date.

Note: The research on KAP for depression is growing rapidly and the findings are consistently encouraging. That said, most studies to date involve relatively small samples, and methodological variation across trials makes direct comparison difficult. Larger randomized controlled trials using standardized protocols are still needed. Journey Clinical's approach is grounded in the best available clinical evidence — and updated as that evidence evolves.


Expected Outcomes for Depression

While no treatment works for everyone and outcomes are specific to each person, patients often report:

Within hours–days:

  • Lifted mood
  • Reduced suicidal ideation
  • Emotional softening
  • Increased sense of hope

Within weeks:

  • Decreased depressive episode frequency and intensity
  • Reduced emotional numbness
  • Renewed motivation and engagement
  • Improved sleep and energy
  • Stronger coping skills
  • Greater capacity for self-reflection
  • More effective therapy sessions

A note on treatment-resistant depression (TRD): For patients who have not responded adequately to prior antidepressant treatment, KAP may offer a clinically meaningful alternative. Multiple systematic reviews and randomized controlled trials demonstrate rapid antidepressant effects in TRD populations, with research suggesting that patients with greater baseline symptom severity may experience the most pronounced response. The mechanism — ketamine's action on NMDA receptors promoting synaptic neuroplasticity — differs fundamentally from conventional antidepressants, which may explain its efficacy in patients where standard treatments have stalled. While individual outcomes vary, many patients with TRD report meaningful relief where prior treatments did not.

Among others, the durability of outcomes is influenced by:

  • Integration therapy
  • Frequency of sessions
  • Engagement with self-care and lifestyle practices

Depression doesn't change in a straight line — below are examples of how core depressive domains can evolve during treatment, from neurobiological shifts to emotional and cognitive changes.

Initial symptom Potential symptom evolution Meaning of the shift
Persistent low mood Mood begins to lift More emotional range
Emotional numbness Feelings return Reconnection with self
Loss of motivation Interest awakens Small steps forward
Hopelessness Perspective widens Future feels possible
Social withdrawal Willingness to connect Less isolation
Cognitive fog Thinking clears More mental clarity
Fatigue and heaviness Energy returns Less physical burden
Negative self view Self-compassion grows Softer inner voice

Who Is a Good Candidate for KAP for Depression?

KAP may be a good fit if you experience:

  • Major depressive disorder (MDD)
  • Persistent depressive disorder (dysthymia)
  • Treatment-resistant depression
  • Postpartum depression and related mood disorders
  • Seasonal affective disorder
  • Depression related to trauma or grief
  • Depression related to serious or chronic medical illness or existential distress
  • Depression resistant to medication or therapy
  • Emotional numbness or anhedonia (loss of pleasure or interest)
  • Bipolar depression (a population where standard antidepressants carry additional risks — ketamine's distinct mechanism may offer an alternative pathway for the depressive component)
  • Passive thoughts of hopelessness or not wanting to be here, where clinically appropriate and with proper supervision

Note that depression rarely exists in isolation. It is commonly comorbid with other mental health and medical conditions, including anxiety and panic disorders, PTSD and trauma-related disorders, intrusive thought patterns (including OCD-spectrum symptoms), chronic pain, sleep disorders, eating disorders, substance use, long-term stress and burnout, or IBS and gut-brain axis-related symptoms, among others. Therefore, it is important to work with your psychotherapist on all symptoms by taking a comprehensive, integrated approach rather than focusing narrowly on depression alone, allowing for accurate assessment, appropriate prioritization of treatment targets, and coordinated interventions that address the full clinical picture and underlying drivers of distress.

To be eligible for treatment, you must also be:

  • Engaged in psychotherapy
  • 18+ years old
  • Medically cleared (on a case by case basis based on the patient's unique history)
  • Have an eligible diagnosis
  • Assessed for safety and clinical appropriateness by your treating clinician
Signs KAP may help your depression
You need relief you need a break from persistent low mood, emotional flatness, or a nervous system that feels shut down (e.g. you struggle to get out of bed, activities that once brought joy no longer do).
You feel stuck you are hitting a wall in some areas of your life (e.g. your relationships, your career, your health, your sense of self or future).
You have tried other modalities you are still struggling despite antidepressants or therapy (e.g. you have tried SSRIs, SNRIs, or talk therapy with limited progress).
You are motivated to change ketamine may open a window of increased psychological flexibility — patients who actively engage in therapy and integration during this period tend to see stronger, more lasting outcomes. This is not a passive treatment or a quick fix; your engagement matters.
You are seeking deeper healing you want to explore deeper levels of personal healing to restore meaning, purpose and forward momentum.

When KAP Is Not Recommended?

Among others, KAP may not appropriate for individuals with unstable medical conditions, contraindicated psychiatric disorders or uncontrolled substance use disorder, including and not limited to:

  • Uncontrolled hypertension or some hypertensive conditions 
  • Severe breathing problems
  • Uncontrolled glaucoma
  • Other unstable medical conditions (e.g. recent traumatic injury or certain cardiovascular conditions etc.)
  • Acute mania or mixed state
  • History of primary psychotic disorder
  • Active suicidal ideation or severe psychiatric instability
  • Active ketamine use disorder 
  • Ketamine allergy or hypersensitivity
  • Pregnancy

These are evaluated during your medical intake by medical professionals alongside any other contraindications based on a full medical and psychiatric history.

This content is intended for informational purposes only and is not a substitute for professional medical advice. Whether KAP is right for you is determined individually by a licensed clinician based on your full medical and psychiatric history.


Ketamine Risks & Side Effects

Ketamine has a well-characterized safety profile, with over 50 years of use in anesthesia and emergency medicine, and an expanding evidence base supporting its rapid and sustained antidepressant effects at subanesthetic doses when administered under appropriate clinical monitoring. Across clinical applications, its safety profile is generally described in the literature as:

  • Well-tolerated in controlled, clinician-supervised settings
  • Rapidly cleared from the body (short half-life, effects are time-limited)
  • Transient side effects are common, predictable, and dose-dependent
  • Serious adverse events are rare when medical screening and monitoring protocols are followed
  • Blood pressure elevation is the most clinically relevant physiologic effect, which is why protocols include blood pressure and heart rate checks before and after dosing
  • Risk of dependence and bladder complications are primarily associated with frequent, chronic, unsupervised use, not with typical medical protocols

Common short-term side effects (most often during or within a few hours) include:

  • Dissociation (feeling detached, “dreamlike,” time distortion) FDA Access Data+1
  • Sedation / sleepiness / fatigue FDA Access Data
  • Dizziness / vertigo / unsteadiness PMC+1
  • Nausea (sometimes vomiting) PMC+1
  • Headache Nature
  • Blurred vision / feeling “off” PMC+1
  • Altered body awareness and spatial orientation.

These effects are typically fleeting, dose-related and time-limited, which is why many protocols include monitoring after dosing. In controlled clinical settings, these are often described as transient and generally mild–moderate, but they still matter for safety planning (no driving same day, fall risk precautions, etc.).

In summary, the clinical safety profile of ketamine is well-established when delivered under medical supervision, including systematic screening, monitoring, and human clinician approval for treatment plans and medication adjustments.


What a KAP Treatment Looks Like (Step-by-Step)

Ketamine-Assisted Psychotherapy (KAP) is a therapist-led mental health treatment model that integrates both psychiatry (medical clearance, prescribing and ongoing monitoring) and psychotherapy (preparation, dosing, and integration sessions). You have a dedicated care team of experienced clinicians here to support you throughout your treatment.

Important distinction: The therapeutic component—not the medication alone—is what differentiates KAP from non-therapist ketamine treatment models. KAP is uniquely structured for emotional change, not only symptom reduction. The therapist’s role is not to direct the experience, but to provide psychological safety, trust, and support when needed.

Step 1: Medical clearance & treatment planning

  • During this initial psychiatry visit, a qualified medical clinician evaluates your health history and current symptoms to determine whether KAP is appropriate and safe for you. If eligible, you receive a personalized KAP treatment plan including a prescription for ketamine lozenges (or other approved ketamine formulations).

Step 2: Therapist-led preparation sessions 

  • These psychotherapy sessions are similar to traditional therapy and tailored to psychedelic-informed care. You and your therapist explore:
    • Your intentions for treatment
    • Any fears or concerns about the experience
    • Emotional readiness and trust-building
    • What support you may need during dosing

Step 3: Dosing session with monitoring & support from therapist

  • A typical ketamine dosing session lasts between 1-3 hours and can take place either in-person in your therapist office or remotely via telehealth. During a dosing session, patients self-administer their ketamine lozenge. Typically, patients are in a comfortable, reclining position wearing an eye mask and listening to calming music. Although a dosing session may be largely an internal experience, the therapist is present the entire time to hold space and provide support as needed. Common experiences may include:
    • Visual imagery or dream-like scenes
    • Emotional insights
    • Shifts in perspective
    • Relaxation or lightness
    • Temporary dissociation

Step 4: Integration sessions for durable change

  • Within the days following dosing, you meet again with your therapist to process and translate what emerged into meaningful, lasting change. This is where transformation becomes durable. Integration often includes:
  • Exploring the memories and insights that surfaced
  • Understanding emotional or cognitive shifts
  • Translating insights into behavioral and emotional change
  • Reinforcing coping strategies and mental health progress

Integration supports durability in KAP treatment, similar to the role of integration in other psychedelic therapy models like psilocybin-assisted psychotherapy and MDMA-assisted therapy in clinical trials.

Step 5: Follow-up with the medical team

  • You continue to follow-up with your dedicated medical professional to monitor safety, progress and outcomes of the treatment. They will prescribe medication refills as appropriate according to your treatment plan. For optimal treatment, it is recommended that your clinician manages all of your psychiatric medications.

While each treatment plan is personalized for each patient, it is common for a full KAP treatment to include 1 medical intake consultation, 1-3 preparation sessions with your therapist, 6-8 dosing sessions with at least 1 integration sessions between each dosing session and follow-up visit(s) with a psychiatric professional. Maintenance dosing may be considered by your medical professional if appropriate.


Insurance & Cost

Understanding the financial investment for Ketamine-Assisted Psychotherapy (KAP) is an important part of planning your mental health care journey. Unlike many traditional therapy services, KAP involves both medical and therapeutic components — and because of that, insurance coverage and out-of-pocket costs may vary.  

Important clarification: the medication ketamine itself is inexpensive in most formulations. What elevates the cost for KAP is clinical time, monitoring, integration support, and medical oversight — not the base price of the drug.

It is common for the full course of treatment of KAP to include: 

  • Matching patient with a therapist who accepts the patient’s insurance
  • 4-6 months of treatment
  • 2 medical consultations
  • ~25 hours of psychotherapy with a KAP trained licensed psychotherapist
  • Ketamine medication for 8 dosing sessions

In this case, the treatment would range from $1400-$1900 with insurance. Payment plans and financing can be available for patients to increase accessibility. To initiate treatment, a patient could make an upfront payment ~$120 followed by an agreed upon payment plan, if eligible for treatment,

Your care team would be able to guide you through your options.


Therapist Insights & Patient Stories

"I have been working with a woman who did not want to live for over 20 years. She is on her 7th dosing session and last week said to me, 'The well of depression is finally emptying.' She is now taking walks, listening to birds, singing and dancing her way through the days. Her husband said the ketamine has been transformative. She says she no longer identifies with her pain. She is happy to be alive."

— Therapist, Journey Clinical Network

"I would rate my Ketamine-Assisted Psychotherapy (KAP) sessions five stars. I was able to lift years of held-in emotions in a matter of 6 sessions. My depression has improved substantially — I have so many more good days than bad. Because of my improvement, my psychiatrist and I are starting to discuss decreasing or discontinuing some of my medication because I am feeling that much better. I am so thankful for KAP and the way it has given me a new life to be so excited about."

— Anonymous, Journey Clinical KAP Patient

Depression and anxiety often travel together. Here's one therapist's account of seeing both shift: “I have been working with a client in their late 50s. They have reported a significant increase in confidence in the workplace. This client has shared multiple examples of standing up for themself and their patients, and has gained the ability to use their voice with upper management in ways that they felt unable to do pre-KAP. This is incredibly exciting given that this client has been experiencing anxiety and depression since they were quite young!”

 — Dana McDowell, LPC

"The amount of positive outcomes that I've seen with my clients doing Ketamine-Assisted Psychotherapy (KAP) is hard to measure. People are seeing improvements in levels of depression and anxiety. I have patients that are finding compassion and forgiveness for themselves in ways that they never imagined possible. The biggest thing that I noticed with KAP versus more traditional therapies is the ability to get towards the root of issues a little bit more quickly than maybe traditional therapy routes have taken us."

— Gianna Gariglietti, LPC, Journey Clinical KAP Provider, Boulder, CO

Alternative Options & Comparison (beyond ketamine)

According to the National Alliance on Mental Illness (NAMI), many treatment options are available for depression, but how well treatment works depends on the type of depression, its severity and the person themselves. For most people, a combination of psychotherapy and medication gives better results than either alone.

Among others, ketamine treatment can be helpful to patients who suffer from depression. See below some examples of various ketamine treatments.

KAP vs at-home ketamine vs. IV Ketamine vs Spravato® 


Relief vs. deeper therapeutic healing: Other ketamine treatments focus on symptom relief. In contrast, KAP may support deeper depression work by helping patients shift the emotional and cognitive patterns that sustain depression — not only the neurochemical imbalances that carry it.

Outside of ketamine modalities, there are other evidence-based therapeutic, medical, and lifestyle interventions that can help patients find relief, restore motivation, and interrupt the patterns that drive depression. Common approaches include:

  • Clinician-led psychotherapy: Talk therapy has an excellent track record of helping people with depressive disorder, and research has shown that the effects of therapy can last longer than the effects of medications alone. Modalities include CBT for restructuring negative thought patterns, ACT for building psychological flexibility and values-based action, IFS for healing inner parts carrying shame or grief, and EMDR for trauma-linked depression
  • Prescription medications for mood stabilization and symptom relief: common antidepressants include SSRIs such as Prozac, Lexapro, and Zoloft, and SNRIs such as Effexor and Cymbalta. For treatment-resistant presentations, FDA-approved options include olanzapine/fluoxetine (Symbyax) and intranasal esketamine (Spravato). Augmentation strategies such as atypical antipsychotics or mood stabilizers may also be considered
  • Neuro-based treatments: Brain stimulation therapies can be tried if psychotherapy and/or medication are not effective, including electroconvulsive therapy (ECT) for depressive disorder with psychosis, or repetitive transcranial magnetic stimulation (rTMS) for severe depression. NAMI
  • Lifestyle interventions and complementary approaches: Alternative approaches including acupuncture, meditation and nutrition can be part of a comprehensive treatment plan. Behavioral activation, regular exercise, sleep hygiene, and reducing alcohol use — which can worsen depressive episodes — are also well-supported adjuncts to clinical treatment.

Frequently Asked Questions

Does ketamine help with depression?

Studies show ketamine can rapidly reduce depressive symptoms -  including in patients who have not responded to prior treatment - especially when combined with therapy.

Does KAP help for treatment-resistant depression?

Yes. Multiple systematic reviews and randomized controlled trials have found meaningful symptom reductions in patients who had not responded to two or more prior antidepressant treatments. Some studies show improvements sustained up to six months when ketamine is combined with structured psychotherapy.

How is KAP different from IV ketamine or at-home ketamine?

KAP includes structured psychotherapy — preparation sessions before dosing and integration sessions after. Research shows that therapy is what creates the possibility of lasting change; ketamine alone opens a neuroplasticity window, but therapy is what determines how much of that window gets used.

Will ketamine interact with my current antidepressants?

Potential interactions are reviewed during your medical intake. Your Journey Clinical clinician evaluates your full medication history before prescribing and can coordinate with your existing providers.

How many sessions will I need?

A typical full course includes 6–8 dosing sessions, with at least one integration session between each. Maintenance dosing may be considered by your medical professional based on your progress and individual needs.

Is ketamine addictive?

In a clinical context, the therapeutic use of ketamine has a low risk of addiction. Misuse risks are discussed during medical intake medical evaluations.  “It's important to acknowledge that Ketamine can be misused. And although cases of dependence exist, the rates are much lower than opioids, alcohol, and stimulants. In a structured environment, we often see ketamine lessen maladaptive substance use rather than fuel it. Because it’s closely monitored and not freely refilled, the risk of addiction is quite low.” — — Dr. Kwasi Adusei, DNP, PMHNP, Journey Clinical Medical Team"

How long does relief last?

Relief is variable depending on multiple factors, however some people feel better for days or weeks, sometimes even months post KAP; therapy extends durability.

Can I drive after KAP?

No. You need a safe ride home.

Is KAP safe?

When medically supervised and paired with psychotherapy, KAP is considered safe for many adults.
