How to Manage Side Effects During Esketamine Therapy
Last Updated: October 25, 2026
Quick Summary
Manage side effects during esketamine therapy by eating light before your session, avoiding alcohol for at least 24 hours, and arranging a driver in advance. During the two-hour observation period, tell staff about nausea, dizziness, or dissociation so they can adjust your care and keep you safe.
- Most sessions run about two hours from start to finish, including observation.
- Dissociation and dizziness typically ease within 30 to 60 minutes, while tiredness can linger all day.
- Use grounding steps like naming five things you see or breathing in for four counts and out for six.
- Escalate any symptom that is new, severe, or following a different course than previous sessions.
- Log symptoms, timing, and what helped after each session, and never change your dose on your own.

What to Expect During a Spravato Session
Esketamine therapy is a supervised treatment for treatment-resistant depression, given as a nasal spray in a clinic.
Here's the short version. You spray the medication yourself under staff direction. Then you stay for observation.
The Spravato prescribing information outlines the required monitoring period. It exists for a reason: side effects like dissociation and blood pressure changes peak early and fade.
The Observation Period and Monitoring
The observation period is the supervised window after each dose. Staff watch for dizziness, sedation, and dissociation. They also track blood pressure at set intervals.
During this time, you rest in a reclining chair. You don't drive, and you don't leave. Bring headphones, a blanket, or an eye mask if that helps you settle.
For a closer look at how monitoring works, read our guide to Spravato side effects monitoring.
What to Avoid Before Spravato Treatment
What to avoid before Spravato treatment: skip heavy meals in the hours before your session, avoid alcohol entirely, and don't drive yourself to the appointment. These steps lower your risk of nausea and keep you safe afterward. But the day of treatment is easier when you think of it as a timeline rather than a single checklist, what to do the day before, before the dose, during the session, and after you get home.
The day before
- No alcohol. Give yourself at least 24 hours clear before a session. Alcohol worsens sedation and can raise blood pressure, two effects esketamine already produces.
- Line up your ride. Arrange a driver in advance, not the morning of. You will not be cleared to drive yourself home.
- Clear the rest of the day. Plan for a slow evening with nothing that needs sharp focus.
Before the dose
Follow your care team's fasting instructions exactly, they vary by clinic, so don't substitute a general rule you read online. A light snack earlier in the day usually sits better than a full meal right before treatment. Skip heavy, greasy, or spicy food close to your appointment. If you're prone to nausea, ask ahead of time about anti-nausea options rather than waiting until your stomach turns.
During the session
You spray the medication yourself under staff direction, then stay for observation. A provider checks your blood pressure and watches for reactions. Most sessions run about two hours from start to finish. Bring headphones, a blanket, or an eye mask if that helps you settle. Don't drive, and don't leave early, the monitoring period exists because side effects like dissociation and blood pressure changes peak early and fade.
Getting home and the rest of the day
- Ride home with your support person. Don't drive, and ideally don't drive until the next day, even if you feel clear.
- Rest and hydrate. Tiredness can linger for the rest of the day, so plan for it rather than fighting it.
- Skip alcohol and anything that needs sharp focus, driving, machinery, important decisions.
A quick pre-session checklist
- No alcohol for at least 24 hours
- Driver arranged for both directions
- Calendar cleared for the rest of the day

Managing Nausea During Esketamine Treatment
Managing nausea during esketamine treatment comes down to timing and small habits. Eat light before your session. Sip water slowly, not in big gulps. Tell your care team the moment your stomach turns.
Nausea is one of the more common complaints, but it usually passes within the observation period. A few things help:
- Keep bland crackers or ginger on hand if your clinic allows
- Sit upright rather than lying flat right after dosing
- Breathe slowly through your nose
If vomiting is severe or won't stop, staff need to know. That's a signal to adjust the plan for next time.
Handling Dizziness, Sedation, and Dissociation
Dizziness, sedation, and dissociation are the three effects patients ask about most. All are expected to some degree. All usually ease as the dose wears off.
Dissociation is a feeling of detachment from your body or surroundings. It can feel strange, but it's a known, temporary effect. Sedation means drowsiness that makes resting easy. Dizziness often shows up as a spinning sensation or unsteadiness when you stand.
Grounding Techniques for Altered Perception
Grounding techniques help you stay calm when perception shifts. Try these during a session:
- Name five things you can see in the room
- Press your feet flat into the floor and notice the pressure
- Breathe in for four counts, out for six
- Hold a familiar object and describe its texture
- Tell staff how you feel so they can reassure you
These simple steps won't stop dissociation, but they make it easier to ride out.
How Long Do Spravato Side Effects Last?
How long do Spravato side effects last? Most effects fade within the two-hour observation period.
Plan for a slow evening. Rest, hydrate, and skip anything that needs sharp focus. Don't drive until your care team clears you, and ideally not until the next day.
Side effects can differ from ketamine, which some patients ask about. Our comparison of ketamine vs esketamine for depression explains how the two differ.
A Symptom-by-Symptom Action Plan for Esketamine Therapy
Most guides tell you which side effects are common. Fewer tell you what to actually do about each one, who handles it, and at what point a symptom stops being routine.
A useful frame is three tiers. Tier 1, self-manage: mild, expected effects you can ride out with the coping steps below. Tier 2, tell staff: effects that are manageable but should be logged and addressed during the observation period. Tier 3, urgent: signs that need immediate medical attention, either in the clinic or after you get home.
| Symptom | What you can try (Tier 1) | What staff can do (Tier 2) | Escalate now (Tier 3) |
|---|---|---|---|
| Nausea | Sit upright, sip water slowly, breathe through your nose, use bland crackers or ginger if your clinic allows | Reposition you, offer anti-nausea options, adjust the plan for next session | Vomiting that won't stop, vomiting with severe headache or confusion, signs of dehydration |
| Dizziness / vertigo | Stay seated, rise in stages, fix your gaze on a still point | Recheck blood pressure, keep you reclined longer, assist with walking | Fainting, a fall, chest pain, weakness or numbness on one side, trouble speaking |
| Dissociation | Grounding steps (below), tell staff how you feel | Reassure you, reduce stimulation, stay with you, document intensity and duration | Feeling you can't stay safe, severe panic, thoughts of harming yourself |
| Sedation | Rest, close your eyes, let it pass | Extend observation, check responsiveness, arrange a safe ride home | Trouble staying awake after the observation period, confusion that doesn't clear |
| Numbness or tingling | Note where it is and how long it lasts | Assess whether it's resolving, document it | Numbness that spreads, lingers well past the session, or comes with weakness |
| Anxiety or distress | Slow breathing, ask for support, use grounding | Talk you through it, adjust the environment, note the trigger for next time | Rising panic, chest tightness, shortness of breath, a sense of doom |
| Blood pressure rise | , (staff-monitored) | Recheck at intervals, keep you resting, follow the clinic's protocol | Severe headache, vision changes, chest pain, shortness of breath |
The expected-versus-emergency distinction
Most esketamine side effects are short-lived and peak early in the observation period. That pattern is what makes them expected.
A practical rule many clinicians use: if a symptom is new, severe, or following a different course than your previous sessions, escalate. If it's familiar, mild, and easing on the same timeline as before, it's usually safe to manage and log.
Grounding steps to use in the moment
When perception shifts, grounding gives you something concrete to do. Try these in order until one helps:
- Name five things you can see in the room.
- Press your feet flat into the floor and notice the pressure.
- Breathe in for four counts, out for six.
- Hold a familiar object and describe its texture.
- Tell staff how you feel so they can reassure you.
These steps won't stop dissociation, but they make it easier to ride out, and telling staff turns a private experience into something they can monitor.
Tracking patterns across sessions
This plan gets more useful the more you use it. After each session, jot down which symptoms showed up, how intense they were, when they started and eased, and what helped. Bring that log to your next appointment. Patterns, a symptom that shows up every time, one that's getting stronger, one that responds to a particular coping step, are exactly what your prescriber needs to fine-tune your care.

Frequently Asked Questions
How long do Spravato side effects last after a session?
Most side effects from Spravato, including dissociation, dizziness, and sedation, peak within 40 to 60 minutes of dosing and ease within two hours. Clinics keep you under observation for at least two hours after each dose to confirm you are stable before you leave. Some people notice mild tiredness or a headache later in the day. If effects linger well beyond the observation period or worsen at home, contact your clinician.
What should I do if I feel dizzy or sleepy after Spravato?
Tell your clinician right away so they can check your blood pressure and adjust your position. Sit or lie back, move slowly when standing, and avoid walking unassisted until the feeling passes. Do not drive, operate machinery, or make important decisions for the rest of the day. Arrange a ride home in advance. If dizziness comes with fainting, chest pain, or a severe headache, seek urgent medical care.
Can I eat before esketamine therapy, and what should I avoid?
Follow your treatment center's instructions, which often include avoiding heavy meals and alcohol before a session. Alcohol and sedatives can amplify sleepiness and raise risk during treatment. Tell your care team about all medications, including stimulants and blood pressure drugs, because some can interact with esketamine. Skip driving yourself and plan for a companion to take you home.
Why do I feel worse after Spravato, and when should I call my clinician?
Some people feel drained, foggy, or emotionally raw for a few hours after a session, which usually settles with rest and hydration. Contact your clinician if you have a severe headache, repeated vomiting, blood pressure that stays high, confusion that does not clear, or thoughts of self-harm. These are not typical recovery patterns and need prompt review. Never wait to report symptoms that worry you.
