Ketamine troches are small compounded tablets that dissolve under your tongue or against your cheek, so ketamine absorbs through the lining of the mouth. At SomaVerse they’re the medicine at the center of every program, prescribed by our medical provider for adults around Lawrence and Kansas City who want ketamine paired with therapy.
The word is pronounced “troh-key,” and the idea is simple. Instead of an IV line or a nasal spray, you hold a lozenge in your mouth for about 10 to 15 minutes while it dissolves. The medicine enters your bloodstream gradually, so the experience rises slowly, which many people find easier to settle into than the fast onset of an infusion.
This page is about the medicine itself: how much of it your body absorbs, how long it lasts, how it compares with IV ketamine and Spravato, what the FDA says, and what it costs. For how the therapy is built around it, see ketamine-assisted psychotherapy (KAP).
Troches might make sense if…
- Needles, IV poles and infusion chairs make your shoulders climb toward your ears.
- You’ve priced IV ketamine around Kansas City, and $350–$700+ per session doesn’t fit your budget.
- You’re sensitive to medications and want an effect that builds gradually rather than all at once.
- You want to stay present enough to notice, feel and even talk during a session.
- You live near Topeka, Lawrence or Johnson County and want sessions close to home: troche sessions happen at all three of our offices.
- You’ve seen ketamine troches sold online and want the same medicine with an actual medical team behind it.
What is a ketamine troche?
A ketamine troche is a compounded lozenge or rapid-dissolve tablet containing racemic ketamine, the same molecule used in anesthesia for decades, at a far lower dose. It’s designed to be absorbed through the mucous membranes under the tongue (sublingual) or between the cheek and gum (buccal).
No drug company makes an FDA-approved ketamine troche, so each one is prepared by a licensed compounding pharmacy from an individual prescription. This also means the strength can be matched to you: the pharmacy can adjust the concentration, and sometimes the flavor, to the dose your provider prescribes.
In practice, you place the troche, let it dissolve slowly without chewing, and hold the saliva in your mouth for as long as you’re instructed. At the end you either swallow or spit what remains. Those small instructions matter, because they change how much medicine you actually absorb.
How much of a troche actually reaches your bloodstream?
Roughly 20–30% of a sublingual dose reaches your bloodstream, compared with essentially all of an IV dose. Published estimates range from about 17% to 30%, and they vary widely from one person to the next.
The most relevant study tested a 25 mg compounded ketamine lozenge made by a hospital pharmacy. Median bioavailability was about 24%, whether it was used under the tongue or swallowed, with a wide spread between people (Chong 2009). A small study in healthy volunteers estimated about 30% for a sublingual tablet and about 20% for a swallowed one (Yanagihara 2003), and an older study measured 17% for oral ketamine against 93% for an intramuscular injection (Clements 1982). All of these studies were small.
Why so low? Some medicine crosses the lining of the mouth directly, but much of it is eventually swallowed, and the liver breaks a large share down before it reaches circulation. One breakdown product, norketamine, is itself active. The liver enzymes that do this work (CYP3A and CYP2B6) are also why some medications can change how ketamine affects you.
The practical takeaway: troche doses aren’t written like IV doses, and the same number of milligrams can feel quite different in two different bodies. That’s why we start low and adjust.
How long do ketamine troches take to work, and how long do they last?
Most people begin to feel a troche within about 10–30 minutes of placing it, and the strongest effects usually ease over the following hour or two. Many people feel close to baseline within a few hours, though you should still plan on not driving for the rest of the day.
Because absorption is gradual, the rise is gentler than an IV infusion. People describe a slow softening: the body grows heavy and thoughts loosen their grip. Some see vivid imagery or revisit memories; others mostly feel deep calm.
There’s also a second, slower timeline. For some people, mood shifts in the hours or days after a dose. Most of what we know about ketamine’s antidepressant effect comes from IV research, where improvement often appeared within hours and faded over about a week without further treatment (Zarate 2006). That’s the reasoning behind a series of sessions with integration in between, rather than a single dose.
A full in-office troche session, including check-in, dosing, the peak and reflection afterward, typically runs about two hours. See in-office ketamine sessions for a step-by-step walk-through.
Why a slower medicine can be a kinder one
In KAP, the state the medicine opens is part of the work, not a side effect to sleep through. A troche’s gradual rise gives you time to arrive: to notice the first shift, breathe with it, and stay in relationship with your guide or therapist instead of being swept under.
That pacing is a big part of why we chose troches. Lower, more gradual blood levels mean many people stay present enough to feel, remember and sometimes speak during a session. For trauma survivors especially, staying in contact with yourself while something difficult moves through can be its own kind of repair.
Gentler isn’t the same as risk-free, or as predictable. ASKP3, a national professional society for ketamine clinicians, describes oral and sublingual ketamine as generally less potent, less durable and less predictable than IV, intramuscular or nasal routes. We take that seriously, which is why every dose is individualized and followed up.
How SomaVerse individualizes your dose
Our medical team, led by our Psychiatry & Ketamine Medical Director, Angel Patterson-Tetuan, PMHNP-BC, sets your dose after a full evaluation, starts conservatively, and adjusts session by session based on how you actually respond.
There is no single “right” troche dose. Body size, liver metabolism, other medications, past experience with ketamine and your own sensitivity all play a part. Some medications, including benzodiazepines and lamotrigine, can blunt the effect, which is one reason we ask about everything you take.
After each session, a medical check-in reviews blood pressure, side effects and what you experienced, and your therapist or guide adds what they observed. Doses go up only when that’s safe and useful; sometimes the right move is to hold steady or come down. It’s the opposite of the very high-dose “hold and spit” protocols that ASKP3 has called highly risky.
- Start low: your first dose is chosen so you and your team can learn how you respond
- Check in after every dose: medical follow-up is built into every SomaVerse program
- Adjust gradually: changes happen one step at a time, never in leaps
- Prescribe only what’s needed: small quantities, filled by a licensed compounding pharmacy
Are ketamine troches FDA-approved?
No. Ketamine is FDA-approved only as an anesthetic. Using it for depression, anxiety, PTSD or other mental health conditions is off-label, and compounded troches have not been evaluated by the FDA for safety, effectiveness or quality.
In October 2023, the FDA warned patients and clinicians about compounded ketamine, including oral and sublingual products used at home for psychiatric conditions. It flagged sedation, dissociation, rising blood pressure, slowed breathing, misuse and bladder symptoms, especially when no provider is monitoring. In June 2026, the agency sent a warning letter to an online troche seller for selling unapproved, misbranded ketamine to consumers without appropriate medical supervision.
We think those warnings are fair, and they describe the opposite of how SomaVerse works. Troches are prescribed only after our team has met and evaluated you, and every client has a ketamine-trained therapist, a guide, a medical check-in after every dose, and an integration plan. If an FDA-approved option suits you better, esketamine nasal spray (Spravato) is approved for treatment-resistant depression, and we’ll help you weigh it honestly.

What do ketamine troches cost?
SomaVerse troche sessions run about $60–$90 per dose, depending on the package. A single dose is $90, 6 doses are $480, 8 are $560 and 12 are $780. Most clients start with the Individual Ketamine Healing Package, $480 for 6 sessions, which includes the ketamine prescription, a Journey Box, medical monitoring, a preparation session and sessions at any of our offices. The medical evaluation, therapy or guide-assisted sessions and integration are billed separately.
For comparison, IV ketamine infusions can cost anywhere from $350 to $700 or more per session. The medication is self-pay, but eligible medical and therapy visits may be billed to insurance, with your usual copays and deductibles. Bundled programs with therapy, guides and integration groups are listed on our pricing page.
