A single-use esketamine device (brand name Spravato) is handed to you by a clinician, who then instructs you to administer one spray into each nostril according to the prescribed protocol before staff monitor your blood pressure, sedation, and dissociation for at least two hours before clearing you to leave. Each session takes place on-site at a certified clinic because the drug can cause transient dissociation, dizziness, and blood pressure changes, so the device is never taken home.
Below is a walkthrough of the first appointment, the dosing sequence, the observation window, side effects, scheduling, and practical logistics so nothing about the process feels unfamiliar on treatment day.
Esketamine Nasal Spray at a Glance: What It Is and Who It’s For
Esketamine nasal spray (Spravato) is the FDA-approved intranasal form of esketamine, prescribed for adults whose major depressive disorder has not improved after at least two adequate antidepressant trials. The FDA first approved it in March 2019 for treatment-resistant depression (TRD), then expanded the indication in 2020 to include adults with major depressive disorder accompanied by acute suicidal ideation, giving clinicians a faster-acting option than traditional SSRIs and SNRIs, which usually take four to six weeks to show meaningful change.
Esketamine works on NMDA glutamate receptors, a different pathway than most oral antidepressants, and mood-circuit effects can appear within hours rather than weeks. Because of that mechanism and its dissociative potential, dosing only occurs in REMS-certified treatment centers (the FDA-mandated Risk Evaluation and Mitigation Strategy program run jointly with the manufacturer). The nasal spray is never dispensed for at-home use, and the medication is never refilled at a local pharmacy.
Eligibility typically requires a confirmed diagnosis of major depressive disorder, documentation that at least two antidepressants from different classes have been tried at adequate doses for adequate durations, and a referral to a participating clinic. Some centers also accept patients with acute suicidal ideation, where faster relief justifies earlier intervention.
Insurance coverage for the drug itself is common, but the REMS monitoring fee varies widely by clinic. Ask the front desk about out-of-pocket costs for the observation period before scheduling your first visit.
Preparing for the First Appointment: What to Know Before You Dose
Small pre-visit choices make the dosing day smoother, and your clinic will usually send written instructions a day or two ahead. Following them closely reduces the chance of your session being delayed by nausea, a blocked nasal passage, or a blood pressure reading that falls outside the safe treatment window.
Food, Drink, and What to Skip the Morning Of
Avoid eating for two hours and drinking for thirty minutes before the dose to lower the chance of nausea during the dissociation window. Skip decongestant nasal sprays and corticosteroid sprays on treatment day, because either can change how the medication absorbs through the nasal lining. If you take a daily antihypertensive, bring it with you and take it at your usual time; a sudden morning gap can push your pressure higher than the clinic wants to see.
Transportation, Medications, and What to Bring
Arrange a driver, because driving is not permitted until the day after a restful sleep following your session, even if dissociation has cleared by evening. Bring a current medication list, including prescription antidepressants, blood pressure drugs, sleep aids, and any supplements, so the clinician can screen for SSRI/SNRI interactions and other safety concerns. A short note about recent substance use (alcohol, cannabis, stimulants) also helps, because the clinic needs to know whether your baseline mental state represents a normal day or a withdrawal or intoxication state.
Knowing your current substance state, though, directly shapes how staff will calibrate and supervise that first dose.
- Two hours food, thirty minutes fluids: Cuts the chance of mid-session nausea.
- Skip other nasal sprays: Decongestants and steroids can block absorption.
- Driver arranged: Driving is off-limits until the next day.
- Medication list ready: Antidepressants and blood pressure drugs matter most.
- Blood pressure check: A brief vitals reading happens before the dose is cleared.
The Dosing Sequence: Step-by-Step Administration in the Clinic
Once staff confirm your vitals and consent, the actual spraying takes only a few minutes. The device is single-use and arrives pre-measured, so your role is to deliver the spray to the right spot in the right order, then hand the device back for disposal. That short mechanical step is the center of the entire visit.
Confirming the Dose and the Protocol Phase
Each device contains 56 mg or 84 mg, and the amount depends on where you are in the induction phase and how you have tolerated prior sessions. The clinic staff will state the dose aloud and check your identification against the prescription. This is the moment to ask any last-minute questions, because once the first spray goes in, the session clock starts.
Spray Technique and Timing
Gently blow your nose to clear mucus, then tilt your head back slightly and insert the tip into one nostril. Press the plunger firmly once, then rest five seconds before pressing again for the second spray that completes that side. Switch to the opposite nostril and repeat the same two-spray motion, because each device covers both nostrils of a complete dose. Hand the used device back to staff for disposal; it is never reused, never saved, and never taken home.
- Step 1: Confirm the dose. 56 mg or 84 mg per device, based on protocol phase.
- Step 2: Clear the nose. A gentle blow removes mucus that can block absorption.
- Step 3: First nostril, two sprays. Five-second rest between presses.
- Step 4: Second nostril, two sprays. Same five-second rhythm.
- Step 5: Return the device. Single-use only; staff handle disposal.
The Two-Hour Monitoring Window: What Happens After You Spray
Because esketamine can transiently elevate blood pressure and cause sedation or dissociation, every session includes a structured observation period before you are cleared to leave. The two-hour window is not optional, and it is the main reason the treatment requires a clinic rather than a take-home kit.
Vitals, Dissociation, and Symptom Tracking
Staff typically check your blood pressure at roughly forty minutes and again before discharge. Dissociation, dizziness, and sedation tend to peak within forty minutes and fade within two hours, though some patients describe a lingering sense of unreality that resolves by the drive home. You remain seated in a calm observation room, often able to rest, listen to music, or quietly read, while a nurse checks in at set intervals. Nausea, when it appears, is usually managed with an offered antiemetic and a slow return to eating once observation ends.
Release Criteria and Same-Day Instructions
Discharge happens only when vital signs and mental status return to baseline. Before you leave, the nurse reviews same-day rules with you and the person driving you home: no driving, no operating machinery, no signing legal documents, and no alcohol or sedating medications for the rest of the day. Those instructions are repeated at every visit because dissociation can feel deceptively mild by early evening, and a clear-headed impression is not the same as a recovered nervous system.
Lingering dissociation into the next day can blur the line between normal grogginess and a genuine safety signal worth flagging.
Side Effects, Safety Signals, and When to Call Your Clinician
Most side effects of esketamine are predictable and short-lived, but a small set of warning signs requires urgent contact with the clinic or emergency services. Knowing the difference between a normal response and a red-flag response is the single most useful piece of safety knowledge for the entire treatment course.
Common Reactions During and After Dosing
Dissociation tops the list, often described as a sense of detachment from the body or a distortion of time and perception. Dizziness, nausea, headache, and mild blood pressure elevation are also common, and a brief reduction in alertness can persist into the evening. These reactions almost always peak within the first hour and resolve by the end of the two-hour observation window, though some patients notice a soft after-effect that fades by morning.
Urgent Warning Signs
Chest pain, a severe headache that does not match your usual pattern, fainting, hallucinations that intensify after you leave the clinic, or shortness of breath all warrant an immediate call to the clinic or a trip to the nearest emergency department. The same applies to persistent vomiting that prevents you from keeping down fluids, or any sudden change in mood that points toward self-harm. The REMS program exists partly so clinics can be reached quickly; keep the after-hours number saved in your phone.
Keep a brief symptom log between sessions: dissociation intensity on a 0–10 scale, hours until you felt fully clear, blood pressure if your clinic provides a cuff, and any mood shift. That log is what your prescriber uses to decide whether to hold the dose, lower it, or extend the interval.
Treatment Schedule, Long-Term Use, and Practical Logistics
Esketamine works on a tapering schedule rather than a daily pill routine, and the rhythm matters as much as the dose. Most patients see the strongest early benefit during the induction phase, then shift into a maintenance pattern that can run for months or longer depending on response.
Typical Frequency and Phase Structure
Induction typically runs twice weekly for the first four weeks. After that, the schedule steps down to weekly or every-other-week maintenance based on how your symptoms respond and how well you tolerate each session. Sessions are paired with an oral antidepressant you already take; never stop your SSRI or SNRI without medical guidance, because the combination is what the FDA approval studied.
Cost, Coverage, and the Calendar Problem
Insurance coverage varies widely, and prior authorization is common. Manufacturer copay programs can lower out-of-pocket cost for eligible patients, and the REMS-certified clinic network affects which centers you can actually use. The biggest logistical hurdle is rarely the drug itself; it is the calendar. Each session includes the dose, the two-hour observation, plus travel time, and the first month alone can mean eight clinic visits.
| Treatment Phase | Typical Frequency | Goal of the Phase |
|---|---|---|
| Induction (Weeks 1–4) | Twice weekly | Rapid symptom reduction and tolerability check |
| Optimization (Weeks 5–8) | Weekly | Stabilize response, fine-tune dose |
| Maintenance (Month 3+) | Weekly or every other week | Sustain remission, watch for relapse signs |
Reassess goals with your prescriber at each phase. Depression symptom scores, functional milestones (returning to work, sleeping through the night, restarting social activity), and side-effect trends guide whether to continue, taper, or adjust. A clear-eyed view of those three signals tends to produce better long-term decisions than chasing any single number on a scale.
Bottom Line
Esketamine nasal spray is delivered, monitored, and cleared entirely inside a certified clinic, so the most useful preparation is logistical rather than technical. Confirm your driver, follow the food and nasal-spray rules, learn the two-spray-per-nostril rhythm, and treat the two-hour observation as part of the therapy. Side effects are usually short-lived and predictable, the rare red flags are easy to recognize once you have seen them once, and the maintenance phase rewards patients who can build a steady calendar around the visits.
FAQ
Can you administer ketamine nasal spray at home?
No. Esketamine is only administered in a REMS-certified clinic under the supervision of a healthcare provider, and the device is never dispensed for home use. The two-hour observation, blood pressure checks, and dissociation monitoring can only happen on-site.
What does ketamine nasal spray feel like during a session?
Most patients describe a temporary sense of detachment, time distortion, or floating that begins within minutes of the first spray and fades within the two-hour observation window. Some people feel mild dizziness or nausea, and a small group reports a brief headache before everything settles.
How long does it take for ketamine nasal spray to work?
Mood effects often appear within hours to a few days, which is faster than most oral antidepressants. Sustained improvement usually requires the full induction phase of twice-weekly dosing for four weeks, followed by a maintenance schedule.
Can you drive after ketamine nasal spray?
No. Driving is not permitted on the day of treatment, and most clinics recommend waiting until the next day after a restful sleep. Even if dissociation has cleared, residual sedation and slowed reaction time are common.
How often is ketamine nasal spray prescribed?
The typical induction schedule is twice weekly for the first four weeks, then weekly or every-other-week maintenance based on response. Your prescriber adjusts the interval based on symptom scores, side effects, and how stable your remission feels.
Is ketamine nasal spray covered by insurance?
Coverage varies by plan and usually requires prior authorization. Manufacturer copay programs and REMS-certified clinic networks both affect the final out-of-pocket cost, so it helps to ask the clinic’s billing team for a written estimate before your first visit.
