PTSD affects millions of adults in the United States, and among those who seek treatment, a significant portion do not achieve adequate relief through the approaches they are most commonly offered. For patients in that category, ketamine therapy represents a different kind of option one whose effectiveness for PTSD is supported by clinical research including a study published in JAMA Psychiatry demonstrating significant, rapid reductions in symptom severity. At The Mood Center in Annapolis and Columbia, Maryland, we work with PTSD patients who have not found sufficient relief through standard care, and the most useful thing we can do at the outset is explain exactly what the treatment process involves.
How We Evaluate PTSD Before Beginning Treatment
The treatment process for PTSD does not begin with the first infusion. It begins with a clinical evaluation that precedes any treatment recommendation. We review your full psychiatric and medical history, the specific nature and duration of your PTSD symptoms, your prior treatment history including which medications and therapy modalities you have tried, at what doses and for how long and any medical conditions that could affect candidacy or require precautions.
PTSD post-traumatic stress disorder is characterized by four clusters of symptoms following exposure to traumatic events: intrusive re-experiencing (flashbacks, nightmares, involuntary memories), avoidance of trauma-related people, places, and stimuli, negative alterations in thought and mood, and marked changes in arousal and reactivity (Mayo Clinic). The severity and pattern of these clusters, and particularly whether they are significantly impairing daily function, informs the clinical picture we evaluate before recommending a treatment approach. For patients and providers navigating the aftermath of traumatic events, understanding acute stress disorder vs. PTSD and the differences between them is an important step before pursuing any treatment pathway.
We also review your current medications. Ketamine can be used alongside most existing psychiatric medications, and we do not discontinue patient-prescribed medications as part of our protocol. Specific combinations may require individual attention, which is why the full medication review is part of every evaluation rather than an afterthought. If your history includes conditions that affect ketamine candidacy such as uncontrolled cardiovascular issues or a history of psychosis we address those directly and honestly rather than proceeding without accounting for them.
The Initial Six-Session Protocol: What Happens at Each Visit
Our standard IV ketamine protocol for PTSD consists of six infusions delivered over three weeks typically two sessions per week. Each session follows the same structure, and knowing what to expect at each visit removes much of the uncertainty that keeps patients from starting.
On the day of an infusion, arrive having fasted from solid food for four hours and liquids for two hours. Arrange transportation you will not be driving yourself home. Wear comfortable clothing. When you arrive, our team checks in with you briefly about how you are feeling, addresses any questions from the previous session, and gets you settled in your private treatment room before beginning.
The infusion itself is administered intravenously over 45 minutes. The room is equipped with a zero-gravity reclining armchair, dimmable lighting, noise-cancelling headphones, and calming music. Your vitals are monitored continuously throughout the session by our medical staff. You will not lose consciousness. As the infusion progresses, most patients experience a dissociative quality a mild sense of floating or detachment from the immediate environment, altered time perception, or a dreamlike awareness. These effects are expected, temporary, and supported by our clinical team.
For PTSD patients in particular, the experience of the infusion may carry emotional texture. Some patients encounter vivid imagery or emotionally charged mental content. Our team is present throughout, and we orient all PTSD patients in advance to the possibility that this may occur and to the evidence that it does not indicate a problematic response. The dissociative window during ketamine infusion has been described in research contexts as potentially therapeutic for trauma a moment of distance from hyperactivated fear responses rather than threatening. Results vary by individual, and we support patients through whatever arises.
Within 15 to 20 minutes of the infusion ending, the dissociative effects resolve. Most patients are ready to leave with their arranged transportation within 30 to 45 minutes of completing the session.
What Is Happening Neurologically During the PTSD Treatment Course
Understanding the neuroscience helps patients make sense of what they are experiencing across the course of treatment. PTSD involves overactivation of the amygdala the brain structure responsible for fear detection and threat response and a corresponding suppression of the prefrontal cortex, which normally moderates and regulates those fear responses (PMC). This imbalance is part of what makes PTSD feel so intractable: the brain’s threat-detection system is running louder than the calming circuits can manage.
Ketamine works through the glutamate system, blocking NMDA receptors and triggering a neuroplastic cascade meaning the brain begins forming new neural connections and reorganizing existing circuits. Research shows that this mechanism produces significant and rapid reductions in PTSD symptom severity, particularly the intrusive re-experiencing and hyperarousal that define the most debilitating features of the condition (PMC). The six-session protocol is structured to allow this neuroplastic process to build across multiple infusions, each one adding to the reorganization the previous session initiated.
Research on repeated ketamine administration in chronic PTSD demonstrates that multiple sessions produce sustained symptom relief that extends well beyond the acute effects of a single infusion (PubMed). This is why the full course of treatment rather than a single session is the appropriate basis for evaluating response.
Ketamine-Assisted Psychotherapy: An Optional but Clinically Meaningful Addition
For PTSD patients, the integration of psychotherapy with ketamine treatment is particularly worth considering. The neuroplasticity that ketamine promotes creates a window in which the brain is more malleable new patterns of thinking and emotional response can take root more readily, and the hyperconsolidated fear memories that sustain PTSD may be more accessible to therapeutic processing. Research supports the integration of psychotherapy with ketamine treatment, showing that the combination may produce more durable and meaningful outcomes than ketamine alone (PMC).
We offer ketamine-assisted psychotherapy (KAP) therapy conducted during or after a ketamine session as an optional add-on. This service is available through your own therapist if they are experienced with KAP, or at an additional charge with a trusted provider at our clinic. Sessions can take place in person or via telemedicine. If trauma-focused therapy has been part of your PTSD treatment history, discussing the KAP option with our team is worth doing before you begin your infusion course.
After the Initial Course: Maintenance and Long-Term Management
After the six-session protocol is complete, we assess your response and discuss the maintenance phase. Booster sessions are available monthly or as needed, and the appropriate frequency depends on how your symptoms respond over time. Some patients find that their gains hold well between monthly sessions; others need less frequent maintenance after the initial course has established a durable baseline.
We remain an ongoing partner in your care during the maintenance phase, not simply a provider you see for discrete treatment courses. We encourage continued coordination with your existing psychiatric or medical providers, and if you do not have a current provider for ongoing mental health support, we can provide a referral.
Making the Process Practically Accessible
The time commitment for a six-session ketamine course is real two sessions per week over three weeks and patients with demanding professional and personal schedules need to plan for it. We offer evening and Saturday appointments at both our Annapolis and Columbia locations specifically to accommodate people who cannot interrupt the standard workday. Many PTSD patients we work with are working adults managing careers, families, and significant obligations. Treatment should not require choosing between getting better and meeting those commitments.
On cost: IV and IM ketamine are self-pay and not currently covered by insurance $425 per session, or $395 per session when purchasing a package of 6, which is our standard initial course. We are in-network with CareFirst, Anthem, Aetna, Cigna, United Healthcare, Tricare, Maryland Medicaid, and Medicare for covered services at our clinic, including TMS and medication management. Patient financing is available for those who need it. For veterans and active-duty military, we encourage you to contact us to discuss which services your Tricare coverage may apply to. We walk through the full financial picture during the consultation, before you have committed to anything.
Frequently Asked Questions
How quickly can I expect to see improvement in PTSD symptoms during the treatment course? Clinical research including a JAMA Psychiatry study has documented rapid reductions in PTSD symptom severity with IV ketamine some patients notice meaningful changes after the first or second infusion. Others experience more gradual improvement across the full course. Results vary by individual, and we track your response throughout the protocol rather than waiting until the end to assess how things are progressing.
Will the ketamine infusion bring up traumatic memories or make PTSD symptoms temporarily worse? Some patients do encounter emotionally charged mental content during the infusion, and we orient all PTSD patients to this possibility before their first session. Our clinical team is present throughout every infusion to support you. Research suggests the dissociative state may actually create therapeutic distance from hyperactivated fear responses rather than amplifying them, though individual experiences vary. We discuss this in detail during your pre-treatment consultation.
Do I have to stop therapy while undergoing ketamine treatment? No and we encourage you to continue therapy if it has been part of your treatment. Ketamine and psychotherapy are complementary, not competing. The post-infusion window in particular may make therapeutic work more effective. If you are not currently in therapy and would like to be, we can provide a referral.
How is IM ketamine different from IV ketamine for PTSD? Intramuscular IM ketamine is an alternative delivery method in which ketamine is injected into a muscle rather than administered intravenously. Both methods work through the same glutamate mechanism. The differences involve absorption rate, onset profile, and clinical circumstances that may favor one method over the other. Our team will discuss which delivery approach is more appropriate based on your individual evaluation.
What if my PTSD symptoms return after the initial course ends? Maintenance booster sessions are available monthly or as needed to sustain the gains from the initial course. Many patients with chronic PTSD find that periodic maintenance is an effective long-term management strategy. The frequency of maintenance depends on your individual response, and we adjust the plan based on what you report between sessions.
Key Takeaways
The ketamine treatment process for PTSD begins with a thorough clinical evaluation of symptom profile, prior treatment history, and medical background before any infusion is recommended.
The standard initial protocol is six IV ketamine infusions over three weeks, with each 45-minute session conducted in a private, medically supervised setting at our Annapolis or Columbia clinic.
Ketamine works by blocking NMDA receptors and triggering neuroplasticity in the fear circuits affected by PTSD clinical research including a JAMA Psychiatry study documents significant, rapid reductions in PTSD symptom severity.
Ketamine-assisted psychotherapy (KAP) is available as an add-on for patients who want to integrate therapeutic work with the neuroplastic window that ketamine creates, and research supports the combination producing more durable outcomes than ketamine alone.
Results vary by individual, and the maintenance phase monthly or as-needed boosters after the initial course is how patients with chronic PTSD sustain the treatment gains over the long term.
PTSD that has not responded to standard care has a documented, evidence-based medical option in ketamine therapy, and the treatment process is more accessible than many patients expect. We offer free consultations at both our Annapolis and Columbia locations, with evening and Saturday availability. Call 443-940-MOOD or schedule online to have a direct, honest conversation about whether IV ketamine therapy is the right next step for your situation.
