PTSD affects millions of people, yet first-line treatments — including trauma-focused therapy and antidepressants — leave a significant portion of patients without adequate relief. For those who have completed prolonged exposure therapy, EMDR, or multiple medication trials and are still struggling with intrusive memories, hypervigilance, and emotional shutdown, the question isn’t whether to keep trying. It’s what to try differently. At Nomad Therapeutics, we work with patients in the Seattle area for whom conventional PTSD treatment hasn’t been enough.
Why PTSD Is Difficult to Treat
Post-traumatic stress disorder (PTSD) develops when the brain’s threat-response system becomes dysregulated following trauma. The amygdala — the brain region central to fear processing and stress response — becomes hyperreactive, treating memories of past events as ongoing dangers (National Institutes of Health). This is why PTSD doesn’t feel like remembering something that happened. It feels like it’s still happening.
That neurobiological reality is also why standard treatments can be difficult to tolerate. Trauma-focused therapies ask patients to revisit and process the very memories their nervous system is working to avoid. For patients with severe or chronic PTSD, that process can feel physiologically overwhelming — not because the therapy is wrong, but because the brain’s threat response is too activated to allow safe access to the material.
What the Research Shows About Ketamine and PTSD
Clinical research demonstrates that ketamine produces significant and rapid reductions in PTSD symptoms, including intrusive memories and hyperarousal (National Institutes of Health). A study published in JAMA Psychiatry found that intravenous ketamine significantly reduced PTSD symptom severity compared to controls, supporting its use as a fast-acting treatment option (JAMA Psychiatry). Research also shows that repeated ketamine administration produces sustained symptom relief in patients with chronic PTSD (National Institutes of Health).
The mechanism behind these effects involves the same glutamate pathway that makes ketamine effective for treatment-resistant depression. By modulating NMDA receptors, ketamine reduces the brain’s hyperactive fear response and creates what researchers describe as a window of increased neuroplasticity. During this window, the emotional reactivity attached to traumatic memories becomes temporarily more manageable. The memory itself doesn’t disappear, but the physiological grip it holds loosens — creating psychological distance that makes therapeutic reprocessing more tolerable and more effective.
This is why ketamine works particularly well as part of a structured psychotherapy program. The medication creates the opening; the therapeutic work determines what you do with it. Our ketamine-assisted psychotherapy model is built around exactly this principle.
How We Treat PTSD at Nomad Therapeutics
Our approach to PTSD treatment follows the same three-phase ketamine-assisted psychotherapy model we use for all conditions: preparation before each session, the medication session itself, and integration therapy afterward.
The preparation phase is especially important for PTSD patients. Working with your therapist before each session helps you set intentions, establish a sense of safety, and approach the ketamine experience with a clear focus rather than arriving unanchored. Patients who prepare well tend to engage more meaningfully with what emerges during the session.
During the medication phase, a registered nurse from our team comes to your home or your therapist’s office and administers ketamine via intramuscular injection. Your nurse monitors your vital signs throughout and remains present for the duration of the session. The acute effects typically last 20 to 30 minutes. What many PTSD patients notice during this time is a reduction in the emotional charge attached to difficult memories — a sense of distance that doesn’t feel like numbing, but like perspective. You can learn more about the logistics of this process on our at-home ketamine therapy page.
The integration phase follows within 24 to 72 hours of each session when possible. This is where the therapeutic work happens. Your therapist helps you process what arose during the ketamine experience, identify patterns or insights that emerged, and build on any shifts in how traumatic material feels. Repeated sessions across our standard six-session protocol create multiple opportunities for this cycle to deepen.
If you already work with a therapist trained in ketamine-assisted psychotherapy, we coordinate directly with them. If you don’t, our Nomad Network connects you with KAP-specialized therapists in Seattle experienced in working with trauma.
Who This Approach Is Right For
At-home ketamine-assisted psychotherapy for PTSD is designed for patients who have not found adequate relief through conventional treatment — whether that’s trauma-focused therapy, antidepressants, or both. It’s particularly well-suited for patients whose PTSD severity makes trauma processing difficult to tolerate, and for those who would benefit from the privacy and comfort of treatment in their own home rather than a clinical setting.
This approach is not appropriate for everyone. A clinical evaluation is required before treatment begins. We encourage you to discuss your full treatment history with our clinicians and to explore your options carefully. Results vary by individual, and we do not make outcome guarantees.
We serve patients throughout Seattle, Tacoma, Bellevue, Kirkland, Redmond, Edmonds, Burien, Olympia, and the surrounding Puget Sound region.
FAQ
Is ketamine approved by the FDA for PTSD?
Ketamine is not currently FDA-approved specifically for PTSD. It is used off-label for this indication based on a growing clinical evidence base. Off-label use means the treatment is administered outside of its FDA-approved indications but is supported by peer-reviewed research and clinical experience. Our clinicians will discuss this distinction with you during your evaluation.
Will ketamine make me relive my trauma?
Not in the way trauma-focused therapies sometimes do. Most patients describe the ketamine experience as creating distance from difficult material rather than immersion in it. The reduction in emotional reactivity is part of what makes the subsequent integration therapy more accessible. That said, experiences vary, and your preparation sessions with your therapist are designed to help you approach the medication session with appropriate grounding.
How does ketamine interact with medications I’m already taking for PTSD?
Some medications can interact with ketamine or affect the experience. Our clinicians conduct a full medication review during the evaluation process. Do not adjust or discontinue any current medications without guidance from your prescribing provider.
How many sessions will I need?
Our standard protocol is six sessions over three weeks, administered twice per week. This regimen has the most supporting clinical evidence for treatment-resistant conditions. Some patients may benefit from maintenance sessions after the initial protocol; that decision is made based on your individual response and clinical picture.
Can ketamine-assisted psychotherapy work alongside my existing PTSD treatment?
Yes. Our model is designed to work alongside existing therapeutic relationships. If your current therapist has KAP training, we coordinate directly with them. If not, we can connect you with a KAP-specialized therapist through our Nomad Network while your existing treatment continues.
Key Takeaways
- PTSD involves a dysregulated fear-response system that makes traumatic memories feel present rather than past — and that can make conventional trauma processing difficult to tolerate.
- Clinical research supports ketamine’s ability to produce rapid, significant reductions in PTSD symptoms including intrusive memories and hyperarousal.
- Ketamine reduces emotional reactivity to traumatic material by modulating the brain’s glutamate system, creating a window of neuroplasticity that makes therapeutic reprocessing more accessible.
- At Nomad Therapeutics, PTSD treatment follows a three-phase KAP model — preparation, medication session, integration therapy — delivered by a registered nurse in your home or therapist’s office. Our dedicated at-home ketamine PTSD treatment page has additional information.
- This approach is designed for patients whose PTSD has not responded adequately to conventional treatment; a clinical evaluation is required to determine candidacy.
PTSD that hasn’t responded to prior treatment isn’t a signal to stop looking for relief — it’s a signal that a different mechanism may be needed. At Nomad Therapeutics, we’re here to have that conversation honestly and help you understand your options. Reach out today for a free consultation.
