Oral Ketamine Therapy
What is Oral Ketamine Therapy?
Oral ketamine therapy represents one of the most exciting and versatile tools in our clinical arsenal at Kismet. For clients who have completed an initial infusion series, oral ketamine can be a remarkably effective way to maintain and extend the benefits gained. Rather than returning immediately for booster infusions, some clients find that a carefully prescribed oral regimen — taken at home under the Nurse Practitioner’s direct medical supervision — allows them to sustain the neurological gains they have worked so hard to achieve while their integration and healing continue to deepen over time.
In the clinical setting, oral ketamine takes on an equally compelling role when combined with active psychotherapy. At low doses, ketamine has a unique capacity to gently lower the psychic defenses that trauma survivors understandably — and necessarily — build around their most painful experiences. For clients whose trauma histories have proven too overwhelming to approach directly in traditional therapy, this subtle but profound shift in the brain’s protective architecture can open doors that have long felt permanently sealed. Our trained psychotherapists work alongside this process with great care and clinical precision, using the medicine as a key that invites the material forward rather than forcing it — always at a pace that feels safe and manageable for the client.
As with all of our services, oral ketamine therapy is never a one-size-fits-all prescription. Whether used at home for maintenance or in-office as part of an active therapeutic relationship, the protocol is tailored specifically to you — your history, your nervous system, and where you are in your healing journey.
How Oral Ketamine Works in Your Body
When you swallow ketamine rather than receiving it through an IV, something interesting happens. The medication travels through your digestive system and gets processed by your liver before it enters your bloodstream. This process, called first-pass metabolism, means that only about 30% of the dose you take actually makes it into your blood as ketamine itself.
This might sound like a problem, but it’s actually part of what makes oral ketamine unique. When your liver processes ketamine, it creates a substance called norketamine. Research shows that norketamine has its own therapeutic benefits for mood and pain. So while less of the original ketamine reaches your bloodstream, you’re getting higher levels of this helpful metabolite instead.
The effects of oral ketamine also come on more gradually than IV ketamine. Instead of the relatively quick onset you experience with an infusion, oral ketamine is absorbed over time, producing a gentler, more extended effect. This slower timeline can actually be an advantage, especially when the goal is maintaining benefits between infusions or creating a therapeutic space that feels manageable rather than overwhelming.
What Research Shows About Oral Ketamine
The science behind oral ketamine for mental health conditions has grown significantly in recent years. While IV ketamine has been studied more extensively, oral ketamine is proving to be both effective and well-tolerated across a range of conditions.
Depression and Treatment-Resistant Depression
Research on oral ketamine for depression shows real promise. In one study, patients with treatment-resistant depression who also had PTSD received oral ketamine as part of their ongoing care. The results were striking: treatment with oral ketamine was linked to a 65 percent reduction in psychiatric hospital admissions and a 70 percent reduction in hospital days. Importantly, no long-term adverse effects were reported.
Another study looked at patients who received a six-week course of oral ketamine for depression. Many of these patients had tried multiple antidepressants without success. The study found that oral ketamine produced meaningful improvements in depression symptoms, with effects that lasted well beyond the active treatment period for many participants.
Post-Traumatic Stress Disorder (PTSD)
Given Kismet’s focus on trauma treatment, the research on oral ketamine for PTSD deserves special attention. A recent open-label study found that 73 percent of participants with PTSD reported their symptoms had been cut by more than half just one week after finishing a six-week course of oral ketamine. Even more encouraging, 59 percent of participants — many of whom had lived with PTSD their entire adult lives — said their symptoms remained less than half of what they started with a full month after their last dose.
The study also found that oral ketamine helped with more than just PTSD symptoms. Participants reported feeling significantly less depressed, less stressed, and less suicidal. They described better sleep, improved quality of life, better social and work functioning, and greater overall wellbeing.
Research suggests that ketamine may work for PTSD through several pathways. It appears to reduce the brain’s fear-based memory formation — essentially helping to weaken the connection between traumatic memories and the intense emotional response those memories trigger. Brain imaging studies show that ketamine can quiet the parts of the brain most associated with threat hypervigilance, which is that constant sense of danger many trauma survivors experience long after the original threat has passed.
Perhaps most importantly for trauma therapy, ketamine seems to create a window where the brain is more open to new learning and change. Several studies have combined ketamine with EMDR — a type of trauma-focused psychotherapy — and found that this combination produces better results than either treatment alone. Ketamine appears to enhance the brain’s ability to update traumatic memories, making them less emotionally overwhelming.
Obsessive-Compulsive Disorder (OCD)
While the research on oral ketamine for OCD is still developing, early studies are encouraging. In a six-week trial of oral ketamine for treatment-resistant OCD, participants showed meaningful reductions in their OCD symptoms. The treatment was well-tolerated, with manageable side effects that tended to be mild and temporary.
Chronic Pain Conditions
Oral ketamine has a long history of use for chronic pain, particularly nerve pain and other pain conditions that don’t respond well to traditional pain medications. The same neuroplastic mechanisms that help with mood disorders also play a role in how the nervous system processes pain signals.
For people living with conditions like fibromyalgia, complex regional pain syndrome, or nerve pain from injury or illness, oral ketamine can help recalibrate how the brain and nervous system respond to pain. This doesn’t mean the pain is “just in your head” — it means that chronic pain involves real changes in how your nervous system processes signals, and ketamine can help address those changes at their source.
How Oral Ketamine is Used at Kismet
We use oral ketamine in two main ways at Kismet: as maintenance therapy following an infusion series, and as part of active psychotherapy.
Maintenance Therapy
For clients who have completed an initial series of IV ketamine infusions and experienced meaningful benefit, oral ketamine offers a way to maintain and extend those gains. Instead of immediately scheduling booster infusions, some clients work with our Medical Director to develop a home maintenance regimen using oral ketamine.
This approach has some additional advantages. It can offer a cost-saving alternative to scheduling a booster infusion. Also, for many people, it provides a steady, sustained level of support that helps preserve the neurological changes created by the initial infusion series while they continue their healing work.
Maintenance protocols are highly individualized. Some clients take oral ketamine once or twice a week. Others use it less frequently depending on their response and needs. The dosing is carefully calibrated to provide therapeutic benefit without producing the dissociative effects that characterize higher doses. You remain fully functional and able to go about your day — this isn’t about creating an altered state but about maintaining the neurological foundation for continued healing.
Ketamine-Assisted Psychotherapy (KAP) with Oral Ketamine
One approach to Ketamine-Assisted Psychotherapy, or KAP, is when oral ketamine is combined with psychotherapy in our office. This is where oral ketamine shows some of its most profound potential, particularly for trauma survivors.
At the carefully calibrated doses we use in therapy sessions, oral ketamine does something remarkable: it gently softens the psychological defenses that trauma survivors necessarily build around their most painful experiences. These defenses exist for good reason — they protect you from being overwhelmed by material that feels too dangerous or too painful to approach directly. But those same defenses can also make it very difficult to process and integrate traumatic memories in a way that allows healing.
Oral ketamine, at therapeutic doses, creates what we might call a window of tolerance. The memories remain accessible, but the protective walls around them become more permeable. This allows our trauma-trained psychotherapists to work with material that might otherwise remain locked away, always at a pace that feels safe and manageable for you.
This isn’t about forcing. If something doesn’t feel safe to approach in a given session, you remain in control of that boundary. What changes is that things which previously felt impossible to touch may begin to feel workable — challenging, yes, but no longer completely off-limits.
Research on KAP for PTSD has shown particularly encouraging results. Studies combining ketamine with EMDR therapy found that the combination is one of the most advanced treatment protocols available in the field of traumatology today.
What to Expect During Oral Ketamine Treatment
If You’re Using Oral Ketamine at Home for Maintenance
If you and Medical Director determine that home maintenance with oral ketamine is a beneficial choice for you, you’ll receive very specific instructions about dosing, timing, and what to watch for. The medication is typically taken at home in a safe, comfortable environment. You should not drive or operate machinery for several hours after taking it, even at maintenance doses.
Most people describe the experience of maintenance-dose oral ketamine as subtle. You might feel mildly relaxed, perhaps a bit floaty or dreamlike, but you remain oriented and functional. The dissociative effects are generally minimal at these doses. Any effects typically fade within a few hours.
You’ll be in regular contact with medical staff here at the practice to monitor your response and adjust dosing as needed. If you experience any concerning side effects or if the medication doesn’t seem to be providing the benefit you’re looking for, the protocol can be adjusted or discontinued.
If You’re Using Oral Ketamine in Therapy Sessions
When oral ketamine is used as part of psychotherapy at Kismet, you take the medication in our office under direct supervision. The session typically lasts about 50-55 minutes followed by additional reflection / journaling time in one of our ketamine rooms. This allows for the medication to take effect, for therapeutic work to happen, and for you to return to baseline before you leave.
You’ll be seated comfortably in our therapy space. After taking the medication, there’s usually a period of 10-15 minutes where you simply rest and allow the medicine to begin working. Your therapist remains present and available throughout.
As the medication takes effect, you may notice a softening of your usual mental barriers. Thoughts and feelings may flow more freely. Memories may feel more accessible. This is the therapeutic window the medication creates. Your therapist will work with you during this time, using established trauma therapy techniques adapted to make use of the unique neurological state the ketamine creates.
The work done during this window is later processed and integrated in follow-up sessions without medication. The ketamine doesn’t do the healing by itself — it creates a temporary condition that makes certain kinds of therapeutic work more possible. The lasting change comes from what you and your therapist do with that window of opportunity.
Safety and Side Effects
Oral ketamine has been used safely for decades, both for pain management and more recently for mental health treatment. The safety profile is well-established, particularly at the doses used for therapeutic purposes.
Common side effects at therapeutic doses are generally mild and temporary. These can include:
- Mild dizziness or lightheadedness
- A feeling of being slightly disconnected from your body or surroundings (dissociation)
- Drowsiness or sedation
- Mild nausea (less common at oral doses than with IV administration)
- Temporary changes in how you perceive time or space
These effects typically resolve within a few hours. Serious side effects are rare at therapeutic doses, especially under medical supervision.
There are some people for whom ketamine — oral or otherwise — is not appropriate. These include people with uncontrolled high blood pressure, certain types of heart disease, active psychosis, or active substance use disorder involving ketamine. A thorough medical evaluation before starting treatment helps ensure ketamine is safe for you.
One concern that comes up frequently is the question of addiction or dependence. At the doses and frequency used for therapeutic purposes, and under medical supervision, the risk of dependence is very low. This is not a medication you’re taking home to use whenever you want. Every dose is prescribed, monitored, and accounted for. The structure of treatment itself — whether maintenance dosing or therapy sessions — is designed to provide therapeutic benefit while minimizing any risk of misuse.
Long-term safety data on therapeutic use of oral ketamine continues to grow. Studies following patients for months to years have not shown significant long-term adverse effects when the medication is used appropriately under medical supervision.
How Oral Ketamine Fits Into Your Overall Treatment Plan
Oral ketamine is a tool, not a cure. It works best as part of a comprehensive treatment approach that might also include psychotherapy, lifestyle changes, other medications if appropriate, and whatever else supports your specific path to healing.
For some clients, oral ketamine serves as a bridge — a way to maintain the gains from an initial infusion series while consolidating the changes in therapy. For others, it becomes an ongoing part of their maintenance plan, used periodically to support continued stability and wellbeing.
In trauma therapy, oral ketamine can be transformative, but it requires the right conditions. You need a therapist who understands trauma, who knows how to work with ketamine-assisted therapy (KAP), and who can help you process and integrate what emerges during medicine sessions. The medicine creates possibility, but the relationship with your therapist is what makes that possibility real.
Is Oral Ketamine Right for You?
If you’ve completed an infusion series and are looking for ways to maintain your progress, oral ketamine might make sense. If you’re working in trauma therapy and finding that certain material remains too defended to approach, ketamine-assisted psychotherapy might offer a pathway forward. If you have treatment-resistant depression, PTSD, OCD, or chronic pain that hasn’t responded adequately to other approaches, oral ketamine deserves consideration.
The only way to know is to talk about it. We can review your history, discuss your current symptoms and goals, look at what you’ve tried before and how you responded, and make an honest assessment about whether oral ketamine has a genuine place in your care.
If it does, we’ll develop a protocol tailored to your specific needs. If it doesn’t, we’ll tell you that directly and explore what else might serve you better.
Oral Ketamine FAQs:
No — and that's actually what makes it so useful as part of your overall treatment. Oral ketamine is taken by mouth at a much higher dose than what is used in an IV infusion to account for how your body processes it, but because it is absorbed through the digestive system rather than directly into the bloodstream, it works more gently and gradually. It won't produce the same deep, immersive experience as an infusion — and that's entirely by design. Think of IV ketamine as the powerful reset, and oral ketamine as the tool that helps you hold onto and build on those gains over time.
Yes — when prescribed and monitored by a trained medical professional, oral ketamine has a well-established safety record. Ketamine itself has been used safely in medical settings for over sixty years. At the doses used for maintenance and therapy-assisted sessions, side effects are typically mild and short-lived. The most common ones are a light feeling of dizziness, mild nausea, or a gentle sense of floating. These usually pass quickly. Our team monitors your response carefully and adjusts your dose as needed to keep your experience as comfortable and effective as possible. Please note that clients receiving oral ketamine — whether at home for maintenance or here in the office for therapy sessions — will need to avoid driving or operating machinery for several hours after taking it.
At the doses used for maintenance — particularly when taken at home — most people feel only a mild, calming shift in their state of mind rather than a dramatic altered experience. The dose is higher than an IV infusion to account for how the body processes it, but because it's absorbed gradually through your digestive system rather than directly into your bloodstream, the experience is gentler and more manageable. When oral ketamine is used during a psychotherapy session here at Kismet, the dose is carefully calibrated to gently soften the brain's natural defenses around painful memories without taking you so far out of your window of awareness that meaningful therapeutic work can't happen.
For maintenance purposes following a completed infusion series, yes — oral ketamine can be prescribed by our Nurse Practitioner for carefully supervised home use. You will receive clear, specific instructions about how and when to take it, what to expect, and what to do if anything feels off. You'll be in regular contact with our medical providers to monitor your response and adjust dosing as needed. You should not drive or operate machinery for several hours after taking it, and we ask that a trusted person be with you or reachable during your first few home sessions until you know how your body responds to it.
This is where something genuinely remarkable happens. At low doses, oral ketamine has a unique ability to gently lower the brain's natural protective walls around traumatic memories — the ones that make certain experiences feel too overwhelming or too frightening to approach directly in regular therapy. With those defenses softened — not removed, just made a little more flexible — our trauma psychotherapists are able to work with you in ways that simply aren't possible otherwise. The medicine creates an opening. The therapist helps you walk through it safely, at your own pace, with great care. Sessions typically last about 50-55 minutes with quiet reflection continuing in one of our on-site ketamine rooms.
Like any treatment, oral ketamine works better for some people than others, and results can vary depending on your specific history, diagnosis, and how your nervous system responds to the medicine. Research shows response rates of approximately 70-75% for conditions like PTSD and treatment-resistant depression, though individual results vary. What we can tell you is that for many of our clients — particularly those maintaining benefits after an infusion series or those whose trauma has been too entrenched to approach through traditional therapy alone — it has been a genuinely meaningful part of their healing.
Like IV ketamine infusions, oral ketamine therapy is not currently covered by most insurance plans. The cost varies depending on dosage amount, whether it is being used for home maintenance or as part of an in-office psychotherapy session. Please speak with the medical provider about specific costs. Psychotherapy may be covered if you have one of the insurance carriers accepted at the practice.
Oral ketamine is generally not appropriate for people with active substance abuse issues, uncontrolled high blood pressure, a current manic episode, or active psychosis. A personal history of substance use disorder doesn't automatically rule it out, but it is something we discuss carefully and honestly during your intake. We would also want to ensure that an appropriate safety plan and monitoring are in place.
