What to Expect at Your First Ketamine Therapy Session

The first ketamine session actually starts well before anyone puts a needle in your arm or a spray in your nose. There's a screening call, a stack of intake forms, a cost conversation, and a full medical evaluation — all before treatment itself begins. A lot of first-time nerves come from not knowing that sequence: patients picture the dosing chair and skip past everything that happens beforehand. Knowing the order of events in advance is the easiest way to walk in without surprises.

This guide covers the parts that are common across clinics and delivery methods — the intake, the paperwork, the cost conversation, the driver you'll need, and how the day itself typically unfolds. For what happens once you're actually in the chair for a specific treatment format — IV drip time, the Spravato observation window, a KAP session's structure — the individual treatment pages linked throughout this guide cover that in detail.

The First Contact and Screening Call

Most people's first interaction with a clinic is a phone call, an online booking form, or a short telehealth screening — not the treatment appointment itself. A staff member or nurse typically asks about your diagnosis, what treatments you've already tried, your current medications, and a few disqualifying factors: uncontrolled high blood pressure, certain heart conditions, active psychosis or a personal/family history of psychosis, pregnancy, and interactions with drugs like MAOIs or lithium. This call exists to confirm the clinic can treat you safely — it's largely built around the same contraindications covered in our guide to ketamine safety and side effects. Some clinics combine this screening with the full medical evaluation in one visit; others schedule the evaluation as a separate appointment with the prescribing clinician, which means two trips (or two video calls) before your first dose.

It helps to have a few things ready before this call: a list of every antidepressant, mood stabilizer, or other psychiatric medication you've tried and roughly how long you were on each, your current prescriptions and dosages, and a short answer for what you're hoping treatment will change. Scheduling itself can take anywhere from a same-week appointment at a smaller practice to a multi-week wait at a busier clinic, so calling around and comparing availability is worth doing before you commit to one location.

Medical Intake and Paperwork

Before or at your first visit, expect a health history questionnaire, a current medication and supplement list, consent forms, and privacy paperwork. Many clinics also use baseline symptom scales — the PHQ-9 for depression, GAD-7 for anxiety, or PCL-5 for PTSD are common — so they can measure whether treatment is actually helping over time. Clinics offering IV infusions often check blood pressure and sometimes request a recent EKG, especially for patients with cardiovascular risk factors. If you've seen a psychiatrist or therapist recently, some clinics will ask permission to request your records. Most of this can be filled out online through a patient portal ahead of time; arriving with it already done shortens the first visit considerably.

Bring a photo ID and, if you plan to seek reimbursement, your insurance card even for treatments the clinic bills as self-pay — front desk staff often use it to generate a superbill automatically rather than requiring a separate request later. If a prior provider is sending records on your behalf, it's worth confirming those arrived before your appointment date rather than assuming the fax or portal transfer went through.

Verifying Cost and Insurance Before You Book

This step looks different depending on the treatment format. Spravato is FDA-approved for treatment-resistant depression and often covered by commercial insurance or Medicare, so a clinic will typically run a prior authorization before scheduling your first dose — a process that can add days or weeks to your timeline. Generic ketamine (IV, IM, oral, or KAP) is prescribed off-label, so most clinics treat it as self-pay and should give you an itemized price sheet covering the evaluation and the initial dosing series before you commit. Ask about superbills for out-of-network reimbursement, payment plans, and cancellation or no-show policies. Our guide to ketamine therapy and insurance breaks down coverage by payer in more detail.

A few questions worth asking on that first call, before you're emotionally invested in a particular clinic: is the initial evaluation billed separately from the first treatment session, does the price you were quoted include the full induction series or just one visit, is a deposit required to hold the appointment, and what happens to that deposit if you need to reschedule. Getting these answers in writing — an email confirmation is enough — is a simple way to avoid a billing surprise later.

Preparing for the Day of Treatment

A few things are worth sorting out before you leave the house:

• Eating: guidance is clinic-specific, but most clinics ask patients to avoid a heavy meal in the hours before dosing — confirm the exact window with your clinic rather than assuming a standard rule.
• A driver:arrange a ride home in advance. This applies to almost every in-clinic dosing appointment, and many clinics won't dose you without a confirmed ride waiting.
• What to wear: loose, comfortable clothing in layers. Patients often feel cold during dosing, and IV appointments are easier with sleeves that push up without effort.
• A support person: policies vary — some clinics let someone wait with you or sit in the room, others keep the treatment space clinician-and-patient only. Ask when you book if this matters to you.
• Comfort items: many clinics provide blankets, eye masks, and headphones or curated playlists, but bringing your own is usually fine if you have a preference.
• Your regular medications: take them on your normal schedule unless the clinic specifically told you otherwise during intake.
• Time off: block off more than the appointment itself. Between check-in, dosing, and post-treatment monitoring, a first visit can take a chunk out of a workday — plan on not driving or handling demanding tasks for the rest of it.
• Hydration: arriving well-hydrated (unless told to fast from liquids too) tends to make blood draws and vitals checks easier for the clinical staff.

Arrival and Your First Appointment Timeline

Clinics generally ask new patients to arrive 15 to 30 minutes early to finish any remaining paperwork and get baseline vitals — blood pressure, heart rate, and sometimes a pulse oximeter reading that continues during dosing. The clinician usually does a final check-in before starting: reviewing consent, confirming nothing has changed since intake, and answering last-minute questions. Depending on the clinic, you may be brought into a private treatment room, a shared infusion suite with recliners, or a therapy office set up for a KAP session — the physical setup varies more than most first-timers expect.

From there, the in-chair experience and total time depend heavily on which treatment format you're receiving — an IV infusion runs on a different clock than a Spravato session or an oral troche, and a KAP appointment is structured around a therapy conversation as much as the dose itself. Rather than restate those specifics here, each format has its own walkthrough:

• IV Ketamine Infusion
• IM Ketamine Injection
• Spravato (Esketamine) Nasal Spray
• Oral Ketamine / Troches
• Ketamine-Assisted Psychotherapy (KAP)
• At-Home Ketamine Therapy

Whichever format you choose, expect a monitored recovery period before discharge — staff typically recheck your blood pressure and confirm you're alert and steady before releasing you to your driver.

Aftercare and Follow-Up

Plan on a quiet rest of the day. Clinics commonly advise against driving, operating machinery, drinking alcohol, or signing anything important for the remainder of the day, since mild grogginess or a lingering dissociative feeling can persist for a few hours. Many clinics send a follow-up symptom questionnaire — often the same PHQ-9 or GAD-7 scale used at intake — within a day or two, both to check in on you and to track whether the scores are moving in the right direction across your treatment series. Expect a set follow-up cadence with the prescribing clinician too: a reassessment partway through an initial infusion series, or a check-in after your first month of Spravato, to decide how your maintenance schedule should look going forward.

If side effects or mood changes worry you between visits, most clinics list a same-day or after-hours contact for exactly that purpose — ask for it at discharge rather than waiting until you need it. Sudden worsening of mood, thoughts of self-harm, or any symptom that feels like an emergency warrants calling 911 or the 988 Suicide & Crisis Lifeline rather than waiting for a callback from the clinic.

How Later Sessions Differ From the First

The first visit is almost always the longest, simply because of the paperwork and evaluation stacked on top of it. Once a clinic has your history on file, later appointments tend to run shorter: a brief check-in on how you've been feeling and any side effects, a quick vitals check, and then dosing — without repeating the full intake. Patients also generally report feeling less anxious by the second or third visit simply from knowing what the room, the process, and the sensation feel like. One exception is switching treatment formats — moving from an in-clinic infusion series to an at-home maintenance program, for example, usually means a new consultation with that program's prescriber, even if you're an established patient elsewhere.

The financial side simplifies too. Once your evaluation is on file and, for Spravato, your prior authorization is approved, later visits usually involve a straightforward copay or a known self-pay rate rather than the estimating and paperwork of the first appointment. And because the clinician already has your baseline symptom scores, later check-ins can focus on whether the dose, spacing, or format is still the right fit — rather than starting the conversation from scratch each time.
