Ketamine therapy is gaining significant attention in mental health treatment as a breakthrough option for conditions resistant to traditional medications. Unlike conventional antidepressants that target serotonin, ketamine works through different neural pathways, offering rapid symptom relief—often within hours rather than weeks. This alternative approach shows particular promise for treatment-resistant depression, anxiety disorders, PTSD, and chronic pain conditions, with success rates of 60-70% in patients who haven't responded to standard treatments.

Innerwell offers expert-guided ketamine therapy for mental health—discover our Innerwell ketamine programs.

Ketamine therapy involves using ketamine, a medication traditionally used as an anesthetic, to treat mental health conditions. First developed in the 1960s and approved by the FDA as an anesthetic in 1970, ketamine has a long history of safe use in medical settings. Its unique properties allow it to induce anesthesia while maintaining respiratory function, making it valuable in emergency and surgical settings.

In the early 2000s, researchers discovered ketamine's rapid antidepressant effects, leading to its off-label use for mental health conditions. Off-label prescribing—using FDA-approved medications for non-approved purposes—is common and legal in medical practice when supported by scientific evidence.

What sets ketamine apart from traditional psychiatric medications is its mechanism of action. While conventional medications primarily target serotonin, norepinephrine, or dopamine systems, ketamine affects the glutamate neurotransmitter system.

As an NMDA receptor antagonist, ketamine may disrupt patterns of negative thought and behavior associated with depression, explaining why it works quickly—often within hours—compared to traditional antidepressants that take weeks to show benefits.

These are the mechanisms of action that affect the brain:

The primary mechanism of ketamine's action is as an antagonist of N-Methyl-D-Aspartate (NMDA) receptors. These glutamate-activated ion channels play a crucial role in excitatory neurotransmission in the brain. Ketamine blocks the NMDA receptor channel in its open state, preventing ion conductance and altering glutamate signaling.

This blockade is particularly potent in certain receptor subtypes. GluN2C/D-containing NMDA receptors appear more susceptible to ketamine's effects compared to GluN2A/B-containing receptors. This differential sensitivity contributes to ketamine's unique profile of effects.

Beyond its immediate effects on neurotransmission, ketamine enhances neuroplasticity and synaptogenesis. It increases the production of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and differentiation of new neurons and synapses.

This enhanced neuroplasticity may explain why ketamine's effects can persist beyond its immediate presence in the body. It potentially "resets" dysfunctional neural circuits involved in depression and other mood disorders.

While ketamine blocks NMDA receptors, it also paradoxically increases glutamate release in certain brain regions. This leads to activation of AMPA receptors, another type of glutamate receptor. This AMPA receptor stimulation triggers molecular cascades that promote synapse formation and strengthen neural connections.

The complex interplay between NMDA receptor blockade and downstream glutamate signaling appears central to ketamine's antidepressant effects.

What Conditions Does Ketamine Therapy Treat?

Ketamine has been proven effective for several conditions, including:

Treatment-Resistant Depression—For patients who haven’t responded to at least two antidepressants, ketamine offers fast relief—helping most of them experience significant improvement, sometimes after just one session.

Major Depressive Disorder (MDD)—Effective not only for treatment-resistant cases but also for broader MDD, with 50–70% response rates and rapid symptom relief.

Anxiety Disorders (GAD, Social Anxiety, PTSD)—Emerging research supports ketamine for anxiety, especially PTSD. Ketamine-assisted psychotherapy (KAP) may deepen emotional processing and introspection.

Bipolar Depression (Not Mania)—Can reduce depressive symptoms in bipolar disorder when carefully managed alongside mood stabilizers to prevent mania.

Obsessive-Compulsive Disorder (OCD)—Some evidence suggests ketamine may quickly reduce obsessions and compulsions by targeting glutamate pathways, though results can vary.

Chronic Pain (CRPS, Migraines, Fibromyalgia)—Ketamine’s pain-relieving effects may benefit chronic pain conditions, especially when depression and pain overlap.

Types of Ketamine Therapy: How is Ketamine Administered 

Ketamine is administered through a variety of routes, such as:

Intravenous (IV) infusion is the most common and well-studied method for ketamine's psychiatric use. Typically, doctors administer a dose of 0.5 mg/kg over about 40 minutes, though dosages may range from 0.1 mg/kg to 0.75 mg/kg depending on patient response and clinical needs.

IV administration provides 100% bioavailability, allowing for precise dosage control and rapid onset of effects. This method requires a clinical setting with medical supervision throughout the infusion.

Intramuscular injections involve administering ketamine directly into a muscle, typically the deltoid or thigh. This method offers rapid absorption similar to IV, though with slightly more variable bioavailability.

IM ketamine is useful when IV access is challenging and provides a practical alternative while maintaining the supervision and safety of a clinical setting.

Sublingual ketamine involves dissolving a lozenge or troche under the tongue, allowing the medication to be absorbed through the oral mucosa. This method offers lower bioavailability (approximately 30%) than IV or IM routes but can be more convenient for maintenance treatments.

Some providers prescribe sublingual ketamine for at-home use between in-office treatments, though this practice varies widely based on provider protocols and patient factors.

Intranasal Esketamine (Spravato®) — FDA-Approved

Esketamine (Spravato®) is a nasal spray formulation of the S-enantiomer of ketamine that received FDA approval in 2019 for treatment-resistant depression. It's administered in a certified healthcare setting with strict monitoring protocols.

It's important to distinguish ketamine from esketamine (Spravato), a related compound with FDA approval for treatment-resistant depression. Both work through similar mechanisms, but esketamine comes as a nasal spray with standardized protocols defined by FDA guidelines.

Oral ketamine tablets have the lowest bioavailability (approximately 20%) due to extensive first-pass metabolism in the liver. This route typically requires higher doses to achieve therapeutic effects.

Some clinics prescribe oral ketamine for at-home maintenance treatment, though this is less common than other methods due to the limited bioavailability and variable absorption.

Rapid Symptom Relief (Hours to Days, vs. Weeks for SSRIs)

Ketamine's most remarkable benefit is its rapid effects, delivering significant symptom relief within hours or days, unlike traditional antidepressants that typically take weeks to work.

For patients in crisis, this quick response can be life-changing and potentially life-saving, particularly for those experiencing suicidal thoughts or severe functional impairment.

Supports Neuroplasticity and Emotional Flexibility

Ketamine promotes neuroplasticity—the brain's ability to form new connections and reorganize itself. This enhanced flexibility may help patients break free from rigid thought patterns and develop healthier cognitive processes.

The neuroplasticity effects may contribute to lasting benefits beyond the immediate drug effects. By promoting the growth of new neural connections, ketamine potentially helps "rewire" dysfunctional brain circuits associated with depression and anxiety.

May Help Break Negative Thought Patterns and Rumination

Many patients report that ketamine helps interrupt persistent negative thinking and rumination. The dissociative experience can provide psychological distance from entrenched thought patterns, offering a new perspective on problems.

This cognitive flexibility can create a window of opportunity for implementing therapeutic techniques and developing healthier thought patterns.

Effective for People Who Haven't Responded to Traditional Treatments

For treatment-resistant depression—defined as failure to respond to at least two adequate trials of antidepressants—ketamine offers hope when other options have failed. Studies show approximately 60-70% of treatment-resistant patients experience significant improvement after ketamine treatment.

This effectiveness in otherwise treatment-resistant cases represents one of ketamine's most important clinical contributions.

Can Accelerate Breakthroughs in Therapy (Especially with Integration Sessions)

Ketamine-Assisted Psychotherapy (KAP) combines ketamine administration with psychotherapy, potentially enhancing the therapeutic process. The altered state ketamine induces can facilitate deep introspection and emotional processing, allowing patients to engage with their thoughts and feelings in new ways.

Many clinicians report that patients can achieve therapeutic breakthroughs more quickly when ketamine sessions are paired with skilled psychotherapy, particularly psychedelic integration therapy that helps process insights gained during ketamine treatments.

Potential Benefits for Suicidal Ideation Reduction

Research shows 55% of patients receiving ketamine experienced a ≥50% reduction in suicidal thoughts within a day. This quick action contrasts sharply with traditional antidepressants, which carry FDA black box warnings about potentially increasing suicidal ideation, particularly in young adults.

This rapid anti-suicidal effect represents one of ketamine's most clinically significant benefits, potentially creating a window of safety during which other therapeutic interventions can be implemented.

Risks and Side Effects of Ketamine Therapy

Common Short-Term Side Effects (Dissociation, Nausea, Dizziness, Increased Blood Pressure)

During and shortly after ketamine administration, patients commonly experience:

Dissociative effects (feeling detached from reality or one's body)

Perceptual disturbances (visual or sensory changes)

These effects typically resolve within hours after treatment, but can be distressing for some individuals. The dissociative experience, while therapeutically valuable for some patients, may be challenging for others, particularly those with a history of dissociative disorders.

Less Common but Serious Risks (Misuse Potential, Bladder Issues with Long-Term High Doses)

The long-term risks of repeated ketamine treatments for psychiatric conditions are still being studied. Concerns include:

Potential for Tolerance or Dependence: While ketamine administered in controlled medical settings appears to have low abuse potential, there are concerns about psychological dependence with repeated use.

Urological Effects: Chronic, high-dose ketamine use has been associated with urinary tract problems, including a condition known as "ketamine cystitis". However, this appears rare at the doses used for depression treatment.

Cognitive Effects: Some studies suggest potential concerns about cognitive effects with long-term use, though research at therapeutic doses is limited.

Discover how ketamine acts on glutamate pathways to deliver fast symptom relief—often within hours—for depression, PTSD, anxiety, and chronic pain.

What Is Ketamine Therapy? Rapid Relief for Treatment-Resistant Depression

What is Ketamine Therapy

When mental health struggles become overwhelming, psychiatric therapy offers a structured, medically informed path to healing. This approach combines medication with psychological insight to address conditions with biological and neurochemical roots, helping millions find their way back to mental well-being. 

Psychiatric therapy can address a wide range of concerns, including anxiety, depression, trauma, and relationship issues. With the right guidance, individuals can gain valuable insights into their mental health and find effective ways to improve their well-being. 

At Innerwell, we offer digital-first solutions that seamlessly integrate traditional psychotherapy with cutting-edge psychedelic integration therapy.

Psychiatric therapy is a specialized branch of mental healthcare provided by medical doctors (psychiatrists) who diagnose, treat, and prevent mental health disorders through a combination of medication management and therapeutic conversations, including online psychiatry. 

Unlike psychotherapy, which focuses mainly on talk-based approaches, psychiatric therapy includes medical interventions that directly address chemical imbalances and biological factors affecting mental health.

The field has changed dramatically over recent decades. Modern psychiatric therapy blends neuroscience, pharmacology, and psychosocial approaches, moving beyond the old rigid biological model. Today's care embraces a whole-person view that considers biological, psychological, and social factors in treatment.

Psychiatric therapy follows a clear process of assessment, diagnosis, and personalized treatment that addresses the brain chemistry behind mental health conditions. A psychiatrist conducts a thorough evaluation of your symptoms, medical history, and life circumstances to create an accurate clinical picture.

During a typical session, your psychiatrist will check how you're responding to medications, assess your current symptoms, and adjust your treatment plan as needed. Sessions usually last 15-30 minutes for medication management, though first evaluations may take 45-60 minutes. Research shows that combining medication with therapeutic conversation works better than either approach alone for many conditions.

The basic principles include evidence-based medication selection, careful side effect monitoring, patient education about your condition and treatment, and making decisions about your care together. This medical foundation sets psychiatric therapy apart from other mental health approaches.

Conditions Treated by Psychiatric Therapy

Psychiatric therapy is particularly effective in treating mental health conditions with significant biological components:

Depression responds well to psychiatric care, often leading to significant symptom reduction, particularly when combined with psychotherapy. Psychiatrists can select the most suitable antidepressant based on your specific symptoms and medical history.

Bipolar disorder requires specialized medical management that psychiatrists are uniquely trained to offer. Mood stabilizers and other medications help balance the extreme shifts between mania and depression.

These conditions primarily respond to antipsychotic medications which psychiatrists prescribe and closely monitor. Ongoing psychiatric care significantly improves daily functioning and quality of life for people with schizophrenia.

Psychiatric therapy can effectively address the underlying brain chemistry associated with various anxiety disorders, including generalized anxiety and panic disorder. Certain medications can relieve debilitating symptoms when carefully prescribed and monitored.

Attention-Deficit/Hyperactivity Disorder (ADHD)

Psychiatrists specialize in diagnosing and treating ADHD, utilizing stimulant and non-stimulant medications that target specific brain chemical systems. Medication can improve functioning in adults with ADHD.

Although talk therapy is often a first-line treatment for PTSD, psychiatric medication can help manage specific symptoms, such as hyperarousal, sleep problems, and co-occurring depression. Research supports a combined approach for best results.

Psychiatric treatment for OCD typically includes specific medications that target serotonin pathways in the brain, with studies showing significant symptom reduction in many patients.

Psychiatric therapy offers unique advantages that complement other mental health treatments:

Faster Symptom Relief: Psychiatric medications can provide faster symptom relief compared to talk therapy alone, especially for severe conditions. For example, some antidepressants may begin showing effects within 1-2 weeks, offering crucial relief during difficult episodes.

Medical Insight: The medical training of psychiatrists helps them identify and address underlying medical conditions that might mimic psychiatric symptoms. This medical perspective creates treatment plans that consider the whole person—not just isolated symptoms.

Reduced Relapse Rates: For chronic conditions like bipolar disorder or schizophrenia, proper psychiatric treatment dramatically reduces relapse rates and hospital stays. Consistent psychiatric care improves both symptom control and overall functioning.

Integrated Approach: The blend of medication and therapeutic conversation creates a powerful effect that often produces better outcomes than either approach alone. This integrated method addresses both the biological roots and psychological aspects of mental health conditions.

At Innerwell, we enhance this integration further with our innovative at-home psychedelic therapy, combining traditional psychiatric care with ketamine-assisted therapy, which has shown remarkable results, including a 69% reduction in depression symptoms. Our distinctive approach blends at-home ketamine therapy with comprehensive digital support through the Innerwell App, which allows patients to track their mood and connect directly with our care team.

What to Expect During Psychiatric Therapy Sessions

Your psychiatric therapy journey begins with a thorough initial evaluation. During this first appointment (usually 45-60 minutes), your psychiatrist will gather detailed information about your symptoms, medical history, family history, and current life situation. This comprehensive assessment creates the foundation for accurate diagnosis and treatment planning.

Follow-up sessions are shorter (15-30 minutes) and focus on medication management, symptom tracking, and adjustments to your treatment plan. Your psychiatrist will ask about your response to medication, any side effects, and changes in your symptoms or functioning. These appointments generally happen more frequently at the start of treatment (every 2-4 weeks) and may spread out to every 1-3 months once your condition stabilizes.

Treatment timelines vary depending on your condition. Studies indicate that acute depression treatment typically lasts 4-9 months, while chronic conditions like bipolar disorder or schizophrenia often need years of ongoing care.

Most patients feel a mix of hope and nervousness during initial sessions. We understand these feelings are natural. As treatment progresses and medications begin working, you might notice gradual improvements in mood, thinking, and daily functioning. Your relationship with your psychiatrist typically grows over time into a partnership focused on your recovery and well-being.

Psychiatric therapy may be beneficial if your symptoms significantly impact your daily life and have not significantly improved with psychotherapy alone. Individuals with conditions known to have strong biological components—such as bipolar disorder, schizophrenia, or treatment-resistant depression—often find psychiatric care essential.

You may be an ideal candidate if you're open to incorporating medication into your treatment and are prepared to participate actively in your care by tracking symptoms and communicating openly about how medications affect you.

It's important to consider potential medication side effects, which can vary significantly depending on the prescription. Additionally, understanding telehealth and informed consent is essential, as psychiatric care often requires commitment to regular appointments and consistent medication adherence for optimal results.

If you're uncertain whether psychiatric therapy is suitable for your situation, beginning with an evaluation by a mental health professional, who can make specialized referrals, offers the best path to finding the right care.

At Innerwell, we specialize in supporting individuals with treatment-resistant depression, those interested in psychedelic-assisted therapies, mental health professionals seeking referral options, and health-conscious individuals looking for innovative mental health solutions.

Our portfolio of services includes Ketamine Therapy, Online Therapy, EMDR Therapy, and Psychiatry Services, providing flexible care options that blend traditional and innovative approaches.

Effectiveness varies by condition, but psychiatric interventions significantly reduce symptoms for many mental health disorders. For conditions like bipolar disorder and schizophrenia, proper psychiatric treatment can reduce relapse rates. Depression and anxiety disorders also show response rates to appropriate medication.

Treatment length varies widely depending on your condition. Acute episodes of depression or anxiety might require 3-6 months of treatment, while chronic conditions often need ongoing care. You'll likely have more frequent sessions (every 2-4 weeks) during initial treatment, then move to less frequent maintenance appointments (every 1-3 months) once stabilized.

Can psychiatric therapy be combined with other types of therapy?

Not only can it be combined with other therapies, but research strongly supports this integrated approach. Many conditions respond best to a combination of medication and psychotherapy. Your psychiatrist may provide both or work with another mental health professional like a psychologist or therapist for comprehensive care.

Is psychiatric therapy covered by insurance?

Most health insurance plans cover psychiatric services, though coverage levels vary. Medicare, Medicaid, and private insurance typically include psychiatric care as part of mental health benefits. The Mental Health Parity Act requires many insurance plans to cover mental health services at levels comparable to physical health services.

Psychiatric medications can have side effects ranging from mild to significant. Common side effects include nausea, headaches, sleep changes, or sexual dysfunction, though these often improve with time or medication adjustments. Your psychiatrist will discuss potential risks and benefits of specific medications, monitor for adverse effects, and make changes as needed to minimize unwanted effects while maximizing benefits.

Learn what psychiatric therapy is, how it works, and why combining meds with talk therapy offers faster relief and better outcomes for many mental health conditions.

What Is Psychiatric Therapy? Benefits, Process & FAQs

What Is Psychiatric Therapy? Professional Mental Healthcare Support

You may be wondering, what is EMDR therapy? Eye Movement Desensitization and Reprocessing (EMDR) therapy helps people process traumatic memories and difficult life experiences. Developed by Dr. Francine Shapiro in the late 1980s, EMDR has become a go-to treatment for post-traumatic stress disorder (PTSD) and other trauma-related issues.

EMDR works on the idea that many psychological problems come from unprocessed traumatic memories stored in our brains. Through a combination of bilateral stimulation (usually eye movements) and focused recall of difficult memories, EMDR activates the brain's natural healing.

Unlike traditional therapy, EMDR does not require you to recount traumatic memories in detail. Instead, EMDR focuses on altering how your emotions, thoughts, and behaviors respond to trauma, enabling your brain to heal naturally.

Major health organizations, including the American Psychiatric Association and the World Health Organization, recognize EMDR as an effective treatment

 for trauma. EMDR is now used for more than just PTSD, including treatment for anxiety, depression, and phobias too.

EMDR therapy follows an eight-phase approach that helps you process traumatic memories while reducing their emotional impact. The core technique involves using bilateral stimulation, typically eye movements, although taps or tones may also be used. During this process, the client briefly focuses on distressing memories which enables the brain to reprocess these memories in a way that diminishes their emotional charge.

The therapy is grounded in the Adaptive Information Processing model which posits that trauma disrupts your brain's natural healing process. The bilateral stimulation mimics REM sleep, helping integrate traumatic memories into broader memory networks, allowing for healthier emotional and cognitive responses.

Research shows that EMDR therapy leads to measurable brain changes, such as reduced activity in the amygdala (the brain's fear center) and increased activity in the prefrontal cortex, which is responsible for higher-level thinking and emotional regulation. 

While EMDR can often work faster than some talk therapies, the number of sessions required depends on the individual's specific situation and trauma history. Many individuals experience significant relief after just a few sessions.

What Conditions or Issues Does EMDR Therapy Treat?

EMDR therapy was initially developed as a PTSD treatment but its applications have since expanded significantly beyond that. Research and clinical practice demonstrate its effectiveness in addressing numerous mental health challenges.

EMDR remains a premier treatment for PTSD. It is particularly effective in helping people process traumatic memories and alleviate symptoms like flashbacks, nightmares, and hypervigilance.

EMDR effectively addresses various anxiety disorders, including generalized anxiety, panic disorder, social anxiety, and specific phobias. Studies indicate that by processing underlying experiences contributing to anxiety, EMDR significantly alleviates symptoms.

When depression is linked to challenging experiences or trauma, EMDR can be particularly beneficial. A study found individuals receiving EMDR improved more than those with standard treatments like fluoxetine.

Growing evidence suggests EMDR helps people with OCD, especially when compulsive behaviors link to distressing memories. In a case study, EMDR proved effective in treating an adolescent's OCD by addressing intrusive images of illness.

EMDR helps with substance use disorders by processing trauma and stressors that drive addiction. In a study, EMDR showed promising results for treating trauma-related symptoms in those with SUD and comorbid PTSD.

For eating disorders like bulimia and binge eating, especially when connected to traumatic experiences, EMDR combined with standard therapies improves outcomes. A study found that EMDR therapy is effective in addressing trauma-related symptoms in individuals with binge-eating disorder (BED), particularly in those with a history of childhood abuse and comorbid PTSD.

EMDR shows promise for chronic pain and unexplained physical symptoms. By desensitizing memories associated with pain onset or exacerbation, it can reduce pain intensity and improve quality of life.

Some studies show EMDR helps resolve sleep problems, especially nightmares and insomnia, by processing disturbing memories or chronic stress that disrupts sleep.

Athletes, artists, and professionals use EMDR for performance anxiety. By neutralizing distressing experiences that block performance, EMDR helps restore confidence and skill.

A 2021 systematic review of 90 articles on EMDR for non-PTSD conditions found positive effects across this diverse range of issues, demonstrating its versatility as a therapeutic approach.

EMDR therapy offers profound benefits for individuals dealing with trauma and other psychological challenges. By reprocessing traumatic memories, it creates meaningful emotional, cognitive, and physical improvements.

EMDR is particularly effective in providing emotional relief. Many clients report a significant reduction in distress about traumatic memories. The therapy helps individuals to:

EMDR helps reframe harmful thought patterns associated with trauma. Clients may experience:

Enhanced ability to challenge negative self-beliefs

Discover how EMDR therapy uses bilateral stimulation to reprocess traumatic memories and relieve PTSD, anxiety, depression, phobias, and more—often in just a few sessions.
