Spravato for Depression: Understanding Treatment, Side Effects, and Results

When antidepressants haven’t made enough of a difference, it’s easy to feel like you’ve run out of options.  Spravato tends to enter the conversation around then. Not as a cure-all, but as something that works on depression from a different angle than anything you’ve likely tried before.

Traditional antidepressants nudge serotonin levels over weeks. Spravato works on a different brain system entirely and can start shifting symptoms within hours for some patients. That’s a real distinction. It’s worth understanding properly – what Spravato treatment actually involves, what the side effects look like in practice, and what the research says about results, stated honestly as ranges rather than promises.

One thing to keep in mind as you read: nothing here replaces an actual evaluation. Whether Spravato fits your situation depends on your full history, and that’s a conversation for a licensed clinician, not an article. 

What Spravato Actually Is?

Spravato is the brand name for esketamine. It is a nasal spray derived from ketamine. Spravato is FDA-approved for treatment-resistant depression and for major depressive disorder with acute suicidal thoughts or behavior. It is the only ketamine-derived medication with that level of formal approval. IV ketamine infusion, which people often mention in the same breath, is used off-label for depression instead.

How does Spravato Work?

Most antidepressants target serotonin – one chemical messenger among many in the brain. Spravato works on glutamate instead, which does a lot more heavy lifting than serotonin does. It’s involved in learning, memory, and the brain’s ability to form and reshape connections generally, not just mood (Delivery of Esketamine for Treatment of Depression). That broader reach is part of the theory behind why Spravato can help when SSRIs haven’t: if depression involves whole networks of the brain going quiet on each other, a treatment that touches a wider system may do more than one that’s aimed at a single pathway.

Mechanically, esketamine blocks NMDA receptors, and that triggers a surge in glutamate activity in areas like the prefrontal cortex. That surge is linked to a rise in brain-derived neurotrophic factor – a protein that helps neurons grow, repair, and form new connections, which is the biological basis of what’s called neuroplasticity. Depression tends to come with reduced neuroplasticity; part of what Spravato may be doing is helping restore some of that flexibility, though researchers are still working out exactly how that translates into the symptom relief patients report.

There’s also a simpler, more practical reason Spravato acts fast: it’s a nasal spray, not a pill. It reaches the brain through the olfactory pathway instead of passing through digestion first, which shortens the path between taking the dose and feeling anything from it.

What Treatment Actually Looks Like

Nobody gets one dose and calls it done. The standard schedule starts with two sessions a week for the first month, then usually eases to weekly sessions for a couple more months, followed by maintenance dosing spaced out further as things stabilize. That front-loading is deliberate – the neurological changes associated with Spravato seem to build across sessions rather than land all at once, so the induction phase leans on frequency early to get that process moving.

Every session happens in a certified clinic under direct observation, and you’re required to stick around for at least two hours afterward while a provider checks your blood pressure and how you’re doing generally. You won’t be driving yourself home that day – arrange a ride before you go in, every time, not just the first visit.

Spravato Side Effects: What’s Normal and What Isn’t

Here’s a closer look at the most common Spravato side effects, the less common but more serious risks, and what you should know before your first appointment.

Dissociation – a floaty, disconnected feeling – along with dizziness, nausea, sedation, and a temporary rise in blood pressure are the side effects patients report most often (GoodRx). They tend to show up within the first half hour or so after dosing and settle down well within the two-hour monitoring window (Bright Horizons Psychiatry). A change in taste and mild vertigo come up often too, and most people find these effects get milder as they go through more sessions.

Spravato also carries what the FDA calls a boxed warning – its most serious warning category – for sedation, dissociation, and respiratory depression, meaning slowed or shallow breathing (Spravato.com). That’s not a scare tactic; it’s exactly why the two-hour observation period isn’t optional. There’s a separate boxed warning about misuse potential, which is why Spravato never leaves the clinic with you – it’s dispensed and administered entirely through the REMS program (Healthline).

Blood pressure is the one to watch most closely. It can stay elevated for up to four hours after a dose, so providers check it before you’re dosed, again around the 40-minute mark, and periodically after that until it comes back down (Spravato.com). If you have uncontrolled high blood pressure or a heart condition where even a temporary spike would be risky, that’s a conversation to have with your provider before you start, not after.

For context on how often side effects actually stop someone from continuing: in FDA trial data, the most common reason patients discontinued Spravato was anxiety, and even that affected just over 1 percent of patients. Worsening depression, blood pressure increases, and dizziness followed, each under 1 percent (FDA Prescribing Information). Side effects in a mild, passing form are common. Severe enough to end treatment is not.

What Results Actually Look Like

There’s no single number that captures this, because response depends heavily on the study and the person. One of the more useful data points comes from a 2023 trial that compared Spravato plus an oral antidepressant against quetiapine – an antipsychotic sometimes added to antidepressants for treatment-resistant depression. At eight weeks, just over a quarter of the Spravato group had reached remission, compared to under a fifth of the quetiapine group. By 32 weeks, nearly half the Spravato group was in remission versus under a third for quetiapine (Reif et al.). That comparison matters more than it might seem – it’s testing Spravato against an active, established treatment, not against a sugar pill, which is a much higher bar to clear.

For patients using Spravato for acute suicidal ideation specifically, trial data has shown improvement within 24 hours of a first dose for many patients, which is part of why it’s sometimes reached for in urgent situations where waiting weeks for relief isn’t an option (SUSTAIN-2 safety data). None of this is a guarantee for any one person. Whether Spravato is working for you is something your provider will typically assess over the first several weeks, not after a single visit.

Frequently Asked Questions

How much does Spravato treatment cost? 

Without insurance, Spravato typically runs $590 to $885 per dose, or roughly $1,000 to $1,500+ per session once in-office monitoring is included. With insurance and prior authorization approved, many patients pay between $10 and $250 per session, and Medicare Part B also covers it for eligible patients.

How long do Spravato side effects last? 

Most common side effects – dissociation, dizziness, nausea, and elevated blood pressure – peak within the first 30 to 40 minutes after dosing and resolve within the required two-hour monitoring window. Blood pressure can occasionally stay elevated for up to four hours.

How quickly does Spravato work for depression? 

Some patients notice improvement within hours to a day of a first dose, particularly for suicidal ideation, though full response is typically assessed over the first several weeks of a treatment course rather than after a single session. Individual timelines vary, and this isn’t something any provider can promise in advance.

Is Spravato safe long-term? 

Long-term studies, including one running up to a year, found that most patients tolerated Spravato well over time, with the majority of side effects being manageable rather than severe. As with any long-term medication, ongoing monitoring by a prescribing provider is part of responsible use.

Can Spravato be used with other antidepressants?

Yes – for the treatment-resistant depression indication, Spravato can now be used either alongside an oral antidepressant or as a standalone treatment, following a 2025 FDA label update. For the acute suicidal ideation indication, it’s used together with an oral antidepressant. Your provider will determine which approach fits your history.
