Spravato Side Effects: What Patients Should Know

Intro

If you are considering Spravato, it is reasonable to ask what treatment days actually feel like. Spravato (esketamine) can help some adults with treatment-resistant depression and some adults with major depressive disorder with acute suicidal ideation or behavior, but it can also cause short-term side effects that need monitoring in a certified medical setting.

Most side effects happen soon after dosing and usually improve the same day. This page explains the common effects patients ask about most, why clinics monitor you after treatment, and when you should contact your care team. For a broader overview of how treatment is scheduled, visit our Spravato near me in Sacramento guide or our Spravato treatment page.

The most common side effects

Spravato can cause several short-term side effects on treatment days. Commonly discussed effects include:

Not everyone has all of these effects, and the intensity can vary from one session to the next. Some patients notice mostly fatigue or dizziness, while others describe dissociation as the most noticeable part of the visit.

When side effects usually happen

For many patients, side effects begin shortly after the nasal spray is given. That is one reason Spravato is not taken at home. Clinics monitor patients after each dose because the period right after treatment is when sedation, dissociation, and blood pressure changes are most relevant.

Many of the common side effects improve over the course of the monitoring period and are gone by later the same day. Even if you feel better before you leave, you still should not drive or do anything that requires full alertness until the next day after a restful sleep.

Why monitoring is required

Spravato is available only through a REMS safety program. In outpatient settings, patients are treated under direct observation and monitored for at least two hours after each session.

That monitoring is not just a formality. Staff typically:

This structured observation period is one of the main safeguards that makes treatment safer. If you want more detail about who may or may not be a good fit, see our Who qualifies for Spravato treatment in Sacramento? article.

What side effects may feel like in real life

Patients often want practical language, not just a list. Here is how these effects are commonly described:

These effects can feel unsettling, especially during early sessions, but they are also part of why the visit includes supervised monitoring rather than a quick medication pickup.

What to plan for on treatment days

A little preparation can make treatment days easier. Patients are usually advised to:

Because nausea can happen, some patients are told not to eat for at least two hours before treatment or drink liquids for 30 minutes before dosing. Your clinic may also give instructions about when to use nasal decongestants or nasal steroids if you take them.

When to contact your clinician right away

Your treatment team should review this with you, but in general you should contact a clinician promptly if side effects feel more intense than expected, last longer than usual, or if you develop new concerning symptoms after leaving the clinic.

Urgent symptoms that deserve immediate medical attention can include:

Spravato also requires careful mood monitoring. If you feel suddenly less safe, have worsening suicidal thoughts, or believe you may harm yourself, call 911 or go to the nearest emergency room right away.

Side effects do not tell the whole story

Some people worry that stronger side effects mean the medication is "working," while others worry that having few side effects means it is not. In reality, symptom improvement and side-effect intensity do not always move together in a simple way.

Your clinician looks at the bigger picture over time: mood symptoms, functioning, tolerability, blood pressure response, and whether treatment still appears appropriate for your diagnosis and goals.

Frequently asked questions

How long do Spravato side effects usually last?

Many side effects start soon after dosing and improve during the observation period or later the same day. Clinics still require monitoring after each treatment and ask patients not to drive until the next day after a restful sleep.

Is it normal for blood pressure to go up during a session?

Spravato can temporarily raise blood pressure, which is why clinics check it before treatment and again after dosing. Your clinician will decide whether the change is acceptable and whether you are stable to go home.

Can I drive myself home if I feel fine?

No. Even if you feel mostly normal by the end of the visit, patients should not drive, operate machinery, or do anything requiring full alertness until the next day after a restful sleep.

Are side effects the same every visit?

Not always. Some patients notice a similar pattern each time, while others find that one session feels easier or harder than another. Your team will monitor how you tolerate treatment over time.

Does dissociation mean something is wrong?

Not necessarily. Dissociation is a known effect of Spravato and one reason monitoring is required. Still, you should tell staff exactly what you are experiencing so they can support you and make sure you remain safe and comfortable.
