How Do You Treat PTSD with Ketamine? Clinicians Weigh In

The treatment of PTSD with ketamine has come a long way since its FDA approval in the 1970s. Its potential for treatment of PTSD was discovered, incidentally, in the 1990s after its use in combat surgeries Later studies showed a reduction of PTSD incidents in soldiers receiving surgery with the use of ketamine as a dissociative anesthetic.

Since then, new studies have led to to exciting findings, including how ketamine changes the brain in those with PTSD. Additionally, veterans with PTSD saw a groundbreaking 80 percent remission rate when receiving ketamine treatment.

Not only have early studies shown ketamine to be effective at treating PTSD, but it works quickly. In fact, many patients experience a reduction in symptoms after a single treatment.

With the increase of studies and news stories, it can be difficult to ascertain exactly how to treat PTSD with ketamine, while understanding what to expect if considering the treatment.

To help bring clarity, we’ve asked medical experts from across the country to share their thoughts and experiences on how to treat PTSD with ketamine.

Dr. Mike Cooper – Innerwell At-Home Ketamine Therapy

One of the most impressive effects of ketamine is its ability to facilitate neuroplasticity, which is essentially the brain’s ability to heal itself and form new pathways. If the brain is visualized as a ski slope, the neural pathways of patients with PTSD can be thought of as ingrained ski tracks that limit the freedom of thoughts, emotion, and behavior. After a ketamine journey these ski tracks get blanketed with fresh powder snow. This creates an opportunity to carve new tracks in the snow, or in other words, build new neural pathways. By building new neural pathways, patients with PTSD can finally experience relief from the fear, hypervigilance, avoidance, and depression that they had previously found so debilitating.

Dr. Thomas Swahn – Swahn Balanced Health

We live our lives from the only vantage point available: looking out at the world from inside our own heads. The beautiful thing about the ketamine experience is that it zooms you out from yourself, providing you an opportunity to see things from a different perspective. Suddenly, the big picture is available, reminding us that there is beauty all around us and our problems are not the insurmountable obstacles we sometimes think they are when we’re too close to them. From the outside, it’s easier to see problematic areas and solutions may come easily. It’s incredible for PTSD because it wraps you in a blanket of serenity and logical acceptance that allows you to decouple your identity from past traumas, changing them from core personality features to merely a chapter in your story. Moving forward without problematic coping mechanisms becomes possible.

Dr. Charles Henry Kirsch, MD – New Horizons Infusion Clinics

PTSD often presents as a layered and complex set of challenges for individuals experiencing it. Our patients have found incomplete resolution from their often debilitating symptoms from traditional therapies. At New Horizon we encourage continuation of pharmacotherapy and counseling while they receive ketamine infusions. Ketamine presents a pathway with unique qualities in our current healthcare ecosystem. Due to the nature of ketamine’s action on the brain, we often see improvement in a patient’s mental health more rapidly than most traditional modalities. It can enable the individual to obtain new perspectives in a few key ways. Some dissociation is often experienced which is likely causal to the change in perspective that frequently occurs. Intellectually, our patients often gain insight and new angles with which to comprehend their lived experience. Emotional challenges often become less severe quickly. This combination can allow for marked improvement in subjective well being and standardized metrics. We work with our patients to titrate the ketamine dosage progressively over a course of six initial hour-long infusions. Often, patients will return for a ‘booster’ infusion if they feel the effects waning. This may occur between one and three months after the initial series.

Sam Mandel – Ketamine Clinics Los Angeles

Ketamine Clinics Los Angeles treats PTSD with ketamine by providing a series of six IV infusions over the course of 2-3 weeks. Each infusion is 50-55 minutes long and is started at a rate of around .6mg / kg of body weight and titrated up or down depending upon the patient’s response. PTSD responds particularly well to ketamine compared to other mental health disorders. Patients are able to revisit trauma without being triggered by it or experiencing an emotional reaction in many cases, providing an opportunity to get closure, gain new insight, and work through details of their experience. Sometimes trauma has been so deeply suppressed that patients don’t even recollect it until it resurfaces during an infusion. This can be a very important healing opportunity. During an infusion, the reaction or response from patients varies widely; some patients laugh for a full hour, others cry non-stop, and most are on an inner journey that doesn’t manifest with any particular outward expression.

In addition to the psychological experience that patients have, the neurochemical response to ketamine that occurs in the brain helps to create new neural pathways. Old ways of thinking and being can be disrupted and replaced with newer, healthier thought patterns and connections in the brain. This can be vital in reframing the trauma of the past and parting ways with an old identity that no longer serves patients. An upgraded operating system is one way some people like to think of it. We strongly advocate for talk therapy and various other modalities, such as EMDR, for the continued healing from various types of trauma. A specialist who understands trauma, and the specific type of trauma any given patient may have, is a critical piece of the puzzle for patients suffering from PTSD to experience complete relief. Fortunately, ketamine is highly effective on its own and can relieve symptoms while providing energy and motivation for patients to pursue counseling and lifestyle optimization, both of which cement the relief the infusions provide. More than 80 percent of our PTSD patients benefit from infusions at Ketamine Clinics Los Angeles. Consultations are free of charge, so we encourage anyone who is interested in learning more to contact us today at

Dr. Marcel Green – Hudson Mind

For people living with PTSD, unrelenting flashbacks often block the healing process. Though ketamine does not wipe away memories of trauma, it does offer a means for disconnecting from the recurring thought patterns that hold the mind hostage.

On a physiological level, we know that ketamine stimulates neurological pathways that make it possible for new thought patterns to emerge. These brain changes are not only helpful for short-term relief, but also make long-term healing possible. For the first time, patients may be able to recognize that their trauma exists separately from them; from this new vantage point, the fear of those memories may not loom quite as large.

At Hudson Mind, our patients experience even greater improvements when treated with both ketamine and Dual Sympathetic Blocks, which temporarily pause the heightened fight-or-flight state of the nervous system. With the nervous system no longer on high alert, PTSD patients are able to comfortably ease into their ketamine experience without amplified fear and anxiety.

Dr. Tyson Lippe, MD – Heading Health

Ketamine has been shown to be beneficial for PTSD in some studies, especially for those who have not responded to traditional treatments such as oral medications and psychotherapy… through the use of ketamine, patients may gain a new perspective on traumatic events which, in turn, can help them process what occurred. Best outcomes occur when ketamine is combined with traditional treatments, especially psychotherapy, for those experiencing symptoms of PTSD.

Dr. Joseph Swider, DO – Heading Health

Post-traumatic Stress Disorder is complex, and for many patients being treated, it occurs alongside depression. Ketamine is used clinically as a rapid-acting antidepressant. Research is also supporting the use of ketamine for PTSD as it is shown to influence parts of the brain that control fear responses, emotional regulation, and memory processing… PTSD is very much like a severe form of anxiety, and ketamine can help a patient better process fear and stress. At Heading we also encourage therapy in tandem with ketamine treatment which is shown to be a more effective method than medication alone.

Dr. Abid Nazeer, M.D. – Advanced Psychiatric Solutions

Ketamine’s antidepressant properties have commanded a historic change in how we view the treatment of depression; however Ketamine therapy is also revolutionary in the treatment of PTSD. The traditional approach to treatment of PTSD involves trauma focused psychotherapy (e.g., EMDR and Rapid Trauma Therapy), as well as medications such as SSRIs (e.g., Sertraline or Paroxetine). They can take weeks to become effective and have about a 33 percent success rate. Ketamine has roughly a 70 percent successful response rate and can become effective very quickly. Ketamine has a medical benefit of triggering your brain to rebuild neurotransmitter pathways and wake up communication between different regions. This is called ‘neuroplasticity,’ and it can help develop new thought patterns surrounding past traumatic events much more easily. During treatment, ketamine can cause dissociation and changes in perception. Though this may be viewed as an adverse effect in some situations, it can more commonly be quite beneficial. In PTSD, there can be reexperiencing of the traumatic memory with vivid clarity, from a whole new vantage point, and none of the anxiety or negative emotions that are usually associated. The result is that the person has a sudden shift in how they view that memory and feel a sense of mastery or control over it, especially when a therapist is guiding you through the process and utilizing this ketamine effect as a tool to assist the trauma therapy.

Debra Ferguson – Daytryp Health

Daytryp’s dosage for PTSD is similar to that of major depressive disorder (MDD). We start low (.25 -.50 mg/kg of bodyweight) and incrementally increase until we find a dose that the client deems the most comfortable. Doses are unique for each client to achieve the benefits they are seeking from treatment and are determined by the practitioner and client together.

During our initial consult meeting, we discuss logistics and provide our clients with pre and post ketamine therapy recommendations, integration tips, and a small journal to ensure they are as prepared as possible for their journey. For all ketamine sessions, we start by taking blood pressure, heart rate and oxygen saturation. We also provide Zofran, an anti-nausea medication. This ensures the client does not risk experiencing nausea, which could negatively affect their journey. Music is an integral piece for KAP so we provide suggested playlists. However, clients are free to use music of their choosing. Eye masks are also provided.

We open the session with a “prayer” for the client and the ketamine molecule. We may discuss intentions at that time. If a client would like to set up their own altar or bring items that are special to them, to assist with their journey, this is all welcomed. We make this a very sacred experience.

Once in the medicine, we monitor respirations and assess for tolerability. We keep them safe and are available for any assistance, if needed. We are dutifully mindful to be supportive but not interfere with the client’s journey.

Once out of the medicine, we assist clients with using the restroom if needed and provide tea along with small organic bites. Once they are able to verbalize about their journey, we act as a scribe, using their journal. We feel this is important as details from their ketamine experience can be fleeting. We find that during this process, valuable insights are made. If the client finds their experience difficult to describe, we may ask questions but this is not a “therapy” session. After the client feels they’ve sufficiently processed, we close the session, again with a “prayer” to the client and the ketamine molecule, asking that they continue to work together in the client’s healing journey. One final post KAP vitals reading, with the session ending when the client is able to walk and tolerate food and fluids.

Daytryp Health offers weekly group sessions where clients are welcome to discuss their journeys, experiences, and insights, further facilitating the integration process.

Ajona Olsen, MSN, APRN, ANP-C – Daytrp Health

Ketamine and more specifically Ketamine Assisted Psychotherapy (KAP) effectively allows the individual to witness events of their trauma that potentially caused PTSD without being drowned in the emotions of the memory. Making novel neural pathways is the cardinal feature of ketamine. Once the individual can integrate these traumatic memories, they often notice a shift in their emotional processes, and they begin to heal.

Jenna Reeder, NP – Jenna Reeder, NP — Integrative Psychiatry

Ketamine’s effectiveness in treating PTSD is not fully understood but research suggests that it is related to specific ketamine-induced changes in the brain. PTSD symptoms can cause loss of synaptic connectivity in various regions of the brain, including the hippocampus, prefrontal cortex, and the amygdala, which may contribute to the complex profile of symptoms associated with PTSD. Ketamine may help treat PTSD by increasing glutamate in the brain which triggers the formation of new neural connections and strengthening of existing ones, therefore reversing trauma-related synaptic abnormalities. Ketamine also increases brain-derived neurotrophic factors (BDNF), a protein that plays a critical role in PTSD treatment and recovery. Elevated BDNF levels in the brain can enhance fear extinction and reduce exaggerated behavioral responses associated with PTSD. When ketamine is combined with psychotherapy to treat PTSD, research has shown prolonged positive treatment effects for patients, as well as lower relapse rates.

Dr. Rafael F. Cruz, MD – Kentuckiana Ketamine Institute

Ketamine remains the fastest and most effective treatment for PTSD and Treatment Resistant Depression. The ketamine dosage sometimes needs individual adjustment for PTSD. Also some PTSD sufferers need an extra boost of IV Vitamin Therapy such as Mega C Meyers, Glutathione, and Amino Acids based on the individual’s deficiencies and medical history. Finally, all need to learn new coping skills which we teach at our practice.

Dr. Radowitz – Nushama

We recognize that unprocessed trauma or difficult life situations are at the root of most mood disorders… Therefore, we treat PTSD with ketamine in a similar manner to how we treat anxiety, addiction, OCD, eating disorders, and various forms of depression. The psychedelic therapy process with ketamine starts with preparation, setting intentions for what they want help processing during their journey—a person with PTSD can choose to reframe their narrative around their trauma. After the treatment experience, through a process of integration with a therapist or coach, people feel safe and supported to work through their trauma without necessarily having to re-experience it. This new perspective can empower them to accept these past events with greater ease, learn and grow from them, let go of unhealthy attachments so that they can transcend and live life with greater ease and peace.

— Dr. Radowitz

Dr. Radowitz has a wealth of experience seeing the effects trauma can have on our physical health firsthand. He joined Nushama to oversee and develop treatment modalities, believing psychedelics are the future of mental wellness as current solutions treat symptoms, not underlying issues.

Dr. Christopher Romig – ARK Integrative Medicine

Ketamine works to help alleviate symptoms of PTSD by targeting the brain’s glutamate receptors, which are involved in memory and learning. By modulating these receptors, ketamine can help reduce the intensity and frequency of intrusive thoughts, nightmares, and other PTSD symptoms. Additionally, ketamine’s fast-acting and long-lasting effects make it a promising option for individuals who have not responded well to traditional therapies for PTSD.

Anthony Townsend – EQNMT

When we experience trauma, our fundamental beliefs about ourselves, others and the world shift. We are often plagued by rigid, negative beliefs that endure long after the traumatic experience, leaving us in continual suffering. The pseudo-psychedelic, ketamine, serves to engender a non-ordinary state of consciousness which allows us to re-examine these beliefs from new perspectives, often breaking their hold on our minds. Ketamine also serves to allow for deep release of intense emotions which can cause deep relief for all of us holding on to pain from the past. Leveraging on ketamine’s ability to make the brain more neuroplastic (cognitively flexible), this molecule also aids therapy in that we are better able to form new habits and shift perspectives more easily to promote faster and deeper healing.

Anthony Townsend is a clinical psychologist, neuropsychologist and co-founder of EQNMT. He is a pioneer of psychedelic-assisted therapy in South Africa.

Risks of Ketamine Treatment for PTSD

While the research into treating PTSD with ketamine is promising, it’s still a young field. Due to the lack of research, federal guidelines on using it for treatment lags as well. This includes standard dosages.

And while ketamine is broadly safe and carries a relatively low risk of adverse side effects, it does have a small risk of addiction.

Now that you have a better understanding of how to treat PTSD with ketamine, it’s important to speak with your doctor. This will help you discover a reputable ketamine clinic for treatment, helping you understand the risks and benefits.
