What is KAP therapy?
Ketamine-Assisted Psychotherapy integrates psychotherapy before and after ketamine sessions to enhance psychological outcomes.
Ketamine is a safe medication that has been widely used for decades since 1970s as an anesthetic in both children and adults.
Not unlike other anesthetics, ketamine has been used illegally for recreational use. Abuse of ketamine can be very dangerous and potentially lethal, as is the case with alcohol and narcotic medications.
That said, when used responsibility by trained clinicians, ketamine can be an extremely valuable option with a wide safety margin to treat a diverse range of conditions, including depression, anxiety, PTSD, trauma, OCD, pain, and suicidal ideation. In fact, the doses used for treatment of psychiatric and mental disorders are well below what is generally used for surgical procedures to anesthetize a patient.
How does Ketamine work?
Biochemically, ketamine interacts with the NMDA receptor to produce anesthetic effects. It interacts with DA receptors to reduce dopamine deficiency in brain circuits involving the hippocampus and other brain nuclei. Addition, it interacts with the AMPA receptor to produce antidepressant effects.
Although the specific mechanism of action of ketamine is still not fully understood by scientists and researchers, it is collectively believed ketamine targets gene expression and protein manufacture in certain important brain pathways or circuits, rather than directly targeting neurotransmitters. It rapidly activates a biochemical pathway associated with synaptic plasticity, the mTOR pathway, by increasing expression of a gene encoding the protein BDNF, which gets the m-TOR pathway going. Hence, activation of this pathway leads to increased number of new synapses in targeted brain regions leading to global restoration of brain synapses, both structurally and functionally, that may have been damaged by a chronically ill brain.
Ketamine infusion is an OFF-LABEL treatment solution. Hence, ketamine infusion treatment is not covered by insurance.

TMS + Ketamine Infusion Therapy
Combined Transcranial Magnetic Stimulation (TMS) and Ketamine Infusion Therapy represents one of the most advanced treatment strategies in modern interventional psychiatry for patients with treatment-resistant depression (TRD), PTSD, bipolar depression, and severe mood disorders.
By pairing the neuroplastic effects of ketamine with the targeted neuromodulation of TMS, this integrated approach addresses both biochemical and circuit-level dysfunction, leading to faster, deeper, and more durable clinical outcomes.
At Lighthouse Psychiatry in Arizona, our protocol is physician-led, evidence-informed, and personalized to each patient’s neuropsychiatric profile.
Individually, both therapies are effective. Together, they offer synergistic benefits that exceed either treatment alone.
Combined Advantages:
- Faster symptom relief than TMS alone
- Greater durability than ketamine alone
- Enhanced neuroplasticity and learning
- Reduced relapse rates
- Effective for highly refractory depression
- Addresses both mood circuitry and neurotransmitter dysregulation
This dual-modality approach is increasingly recognized as a next-generation standard for severe or complex depression.
Combined therapy is clinically applied for:
- Treatment-resistant depression (TRD)
- Major depressive disorder
- PTSD and trauma-related depression
- Bipolar depression
- Severe anxiety disorders
- Chronic suicidal ideation
- Depression with cognitive impairment
- Comorbid depression and chronic pain
- Comprehensive Psychiatric Evaluation
Neuropsychiatric assessment, prior treatment review, and safety screening.
- Personalized Treatment Sequencing
Protocols may include:
- Ketamine priming before TMS
- Concurrent ketamine + TMS phases
- TMS stabilization followed by ketamine maintenance
- TMS Neuromodulation
Non-invasive, FDA-cleared stimulation targeting depression-related cortical circuits.
- Ketamine Infusion Therapy
IV ketamine administered in a monitored medical setting to rapidly reduce depressive symptoms and enhance plasticity.

Outcome tracking, relapse prevention, and long-term planning.
This advanced protocol is typically recommended for patients who:
- Failed ≥2 antidepressant trials
- Had partial or short-lived responses to TMS or ketamine alone
- Have severe, recurrent, or complex depression
- Experience suicidal ideation
- Have comorbid PTSD or bipolar depression
- Require faster stabilization than traditional treatments allow
At Lighthouse Psychiatry, combined TMS and ketamine therapy is delivered with:
- Board-certified psychiatric oversight
- Continuous monitoring
- FDA-cleared TMS devices

Frequently Asked Questions (FAQ)
Ketamine therapy is an off-label psychiatric treatment that uses ketamine, a medication originally developed as an anesthetic, to help manage certain mental health conditions. At lower doses used in psychiatric settings, ketamine affects NMDA receptors and glutamate signaling in the brain. It may produce relatively rapid improvements in depressive symptoms in some patients.
Ketamine is FDA-approved as an anesthetic, but IV ketamine has not been FDA-approved specifically for treating depression. Its use for psychiatric conditions such as treatment-resistant depression is considered off-label. Esketamine (Spravato), a related medication administered as a nasal spray, has separate FDA-approved indications for certain forms of depression.
Ketamine therapy may be considered for individuals with treatment-resistant depression or certain other psychiatric conditions when clinically appropriate. A psychiatric provider evaluates the patient's diagnosis, previous treatment history, medical conditions, medications, and potential risks before recommending treatment.
Ketamine may help some people with treatment-resistant depression, particularly those who have not experienced sufficient improvement with traditional antidepressants. Unlike many conventional antidepressants, ketamine can produce relatively rapid changes in depressive symptoms. However, individual responses vary, and ongoing psychiatric care is important.
Some patients experience improvements in depressive symptoms within hours or days following an initial ketamine infusion. Others may require additional sessions before experiencing meaningful changes. Treatment response varies, and ketamine therapy is not guaranteed to work for everyone.
For psychiatric treatment at Lighthouse Psychiatry, ketamine is administered through IV infusion in a controlled medical environment with clinical monitoring. The dose, infusion duration, and treatment schedule are determined by the provider based on the patient's clinical needs and medical history.
During a ketamine infusion, patients receive medication intravenously in a medically supervised setting. Healthcare professionals monitor the patient's condition and vital signs throughout treatment. Some patients experience temporary changes in perception, relaxation, or dissociation. The provider also explains what to expect before and after the infusion.
Ketamine has established medical uses as an anesthetic, but psychiatric treatment requires careful patient selection and clinical monitoring. Potential side effects include dizziness, nausea, increased blood pressure, sedation, and dissociation. Repeated or prolonged exposure also raises concerns about misuse and certain urinary or cognitive effects. Treatment should only be undertaken with appropriate medical supervision.
Potential side effects include nausea, dizziness, elevated blood pressure, temporary changes in perception, sedation, and dissociation. Some patients may also experience headaches or anxiety during or after treatment. Your provider should review potential risks and precautions before treatment begins.
Ketamine-Assisted Psychotherapy (KAP) combines ketamine treatment with structured psychotherapy. The approach integrates medical treatment with therapeutic support to help patients explore emotional experiences, develop insights, and work toward meaningful behavioral changes. At Lighthouse Psychiatry, the program combines ketamine infusions with psychotherapy integration sessions.
Ketamine infusion therapy refers to the medical administration of ketamine through an IV infusion. Ketamine-Assisted Psychotherapy combines ketamine treatment with structured psychotherapy before or after the infusion. KAP adds a therapeutic component to help patients process experiences and support ongoing psychological work.
Ketamine is being studied and used off-label in certain clinical settings for conditions such as PTSD and anxiety disorders. However, the evidence and clinical recommendations vary by condition. A psychiatric evaluation is necessary to determine whether ketamine treatment is appropriate and whether other established treatments may be more suitable.
Yes. Ketamine infusion therapy typically uses IV ketamine administered under medical supervision, while Spravato uses esketamine nasal spray. Spravato is FDA-approved for specific depression indications and requires administration under a restricted REMS program. IV ketamine for psychiatric treatment is generally off-label and follows a different treatment protocol.
The duration of improvement varies between patients. Some experience relief that lasts days or weeks, while others may require additional treatment to maintain improvement. The treating provider monitors symptoms and determines whether further treatment or other forms of psychiatric support are needed.
Yes. Ketamine therapy can be incorporated into a broader treatment plan that includes psychotherapy. Ketamine-Assisted Psychotherapy integrates medical treatment with structured therapeutic sessions to help patients process emotions, develop coping strategies, and work toward sustained behavioral changes.
IV ketamine infusion for psychiatric conditions is generally considered an off-label treatment and is not routinely covered by health insurance. Coverage varies by insurer and individual policy. Patients should confirm benefits directly with their insurance provider and discuss self-pay, reimbursement, or financing options with Lighthouse Psychiatry.
The cost of ketamine infusion therapy depends on the number of sessions, treatment protocol, psychiatric evaluations, psychotherapy services, and individual clinical needs. Because IV ketamine for depression is generally an off-label treatment, patients may need to pay out of pocket. Contact Lighthouse Psychiatry for current pricing and available payment options.
