What to Expect at Your First Ketamine-Assisted Therapy (KAP) Session

"Ketamine-assisted therapy" (often shortened to KAP) describes a specific clinical model: a licensed prescriber administers ketamine in a monitored setting, paired with the support of a therapist or trained sitter and a structured conversation afterward. If you have never done this before, the format can feel unfamiliar. Here is what actually happens, step by step, so you know what to expect walking in. For background on ketamine itself, start with our ketamine therapy guide.

Before your first session: the screening call

Every legitimate KAP program starts with a screening step before any dose is scheduled. Expect a call or intake appointment that covers:

• Medical history, including blood pressure, heart problems, and prior anesthesia reactions.
• Mental health history, including any personal or family history of psychosis, since dissociative states can be destabilizing for some people.
• A full medication list — prescriptions, supplements, and over-the-counter products. See our psychedelic medication safety guide for why this step matters and which combinations prescribers screen for.
• Your goals for treatment, so the therapist can help you set an intention for the work.
• Logistics: who is driving you home, and where the session will take place.

Programs vary in format here. Some run this entirely by telehealth with an at-home lozenge protocol; others require an in-person psychiatric evaluation before the first in-office dose. Ask directly which model a clinic uses before you book.

Who is in the room

This is one of the biggest differences from a self-guided or recreational setting: you are not managing the session alone. Depending on the program, you can expect some combination of:

• A prescriber (psychiatrist, nurse practitioner, or physician) who administers or oversees the dose and monitors vital signs.
• A KAP-trained therapist or sitter whose job is to stay present with you through the dosing window, offer grounding if needed, and hold space without directing the experience.
• Clinic or nursing staff, in in-office IV or IM settings, who handle monitoring equipment and safety checks.

In at-home telehealth models, the "sitter" role is usually filled by a screened, sober adult you designate — a partner, friend, or family member — with the prescriber available by phone or video if needed.

What a session actually looks like

Formats differ by clinic, but a typical in-office session follows a predictable arc:

• Arrival & check-in (10–15 min): Vital signs are checked. You confirm you have a ride home. You and your therapist briefly revisit your intention for the session.
• Setup (10–15 min): You get comfortable — often reclined, with an eye mask and music. The prescriber or nurse administers the dose (nasal spray, IM injection, IV infusion, or an oral lozenge you dissolve under supervision).
• Dosing window (roughly 40–60 min): The dissociative effects set in and run their course. Your therapist or sitter stays present but mostly quiet, checking in only as needed.
• Return & recovery (20–40 min): As the dissociation fades, you re-orient to the room. Vital signs are checked again before you are cleared to move to the integration conversation.
• Integration conversation: A shorter talk with your therapist about what came up, before you head home with your ride.

The dosing window: what dissociation feels like

During the dosing window, most people experience some degree of dissociation — a sense of distance from your body, your surroundings, or your usual sense of time. Some people describe floating, a dreamlike quality, or a felt sense of being outside normal waking awareness. This is the expected drug effect at therapeutic doses, not a malfunction or a bad reaction.

Other short-term effects can include nausea, dizziness, blurred vision, or a temporary rise in blood pressure, which is exactly why this happens under monitoring rather than alone. Our ketamine side effects guide covers the full list of what to expect and what warrants a call to your prescriber.

Right after: recovery and discharge

You will not be discharged the moment the dissociative effects fade. Clinics keep patients in observation — often around two hours total from dosing, consistent with how Spravato (esketamine) monitoring windows are structured — until vital signs and alertness are back to baseline. You cannot drive yourself home after a session; arranging a ride is a standard requirement, not an optional precaution.

Integration: the conversation after

In KAP, integration is not a separate service you can skip — it is built into the treatment model. The short conversation right after dosing is a first pass. Many programs also schedule a separate, longer integration session in the days that follow, either with the same therapist or a dedicated integration specialist.

This matters because the material that surfaces during a dissociative state does not automatically translate into lasting change on its own. Talking it through, in the hours and days after, is where a lot of the therapeutic work happens. Our integration therapy guide explains what a good integration relationship looks like, whether or not it is bundled into your KAP program.

How many sessions, and how often

Course length depends on the access model. Spravato follows an FDA-labeled schedule — typically twice weekly for the first month, then tapering. IV or IM ketamine programs often run a series of about six sessions over two to three weeks, followed by maintenance dosing as needed. At-home telehealth lozenge programs vary by prescriber. See our ketamine therapy guide for a side-by-side comparison of these access models, and our ketamine therapy cost guide for what each course typically runs.

How this differs from a psychedelic ceremony

It is worth being explicit about this, because the language around psychedelics can blur it: clinical KAP is not a ceremony. There is no plant medicine, no ceremonial framing, and no facilitator operating outside a licensed medical and therapeutic scope. The setting is a clinic or a structured telehealth visit, the substance is an FDA-regulated Schedule III drug administered or prescribed by a licensed clinician, and the support model centers on a trained therapist and prescriber rather than a ceremonial guide. If you are looking into a ceremony-style session with a different substance instead, our ceremony preparation guide covers that separate model.
