Esketamine, or Spravato, explained
What FDA-approved esketamine actually is, who it tends to help, what a supervised session looks like, and how to think about cost, safety, and expectations.
Esketamine, sold as Spravato, is one of the first genuinely new mechanisms for treating depression in decades. It is not a street drug, not a wellness trend, and not a cure. It is an FDA-approved medication given under medical supervision, and for some people it works when older options did not.
What it is
Spravato is a nasal spray form of esketamine, a molecule related to ketamine. The U.S. Food and Drug Administration approved it for adults with treatment-resistant depression, meaning depression that has not responded well to other antidepressants, and for depressive symptoms in adults with acute suicidal thoughts or behavior, used together with an oral antidepressant.
What makes it different is the mechanism. Standard antidepressants mostly act on serotonin and related systems and can take weeks to help. Esketamine acts on the brain's glutamate system, and some people notice a change in days. For someone who has waited out several slow medication trials, that speed can matter.
What a session actually looks like
Because of how it works, esketamine is not a prescription you fill and take at home. It is given in a certified healthcare setting under a program the FDA calls a Risk Evaluation and Mitigation Strategy. In practice, a typical visit looks like this:
- You take the nasal spray yourself, in the clinic, under staff supervision.
- You stay and are monitored for about two hours afterward, because it can temporarily affect blood pressure, alertness, and perception.
- You do not drive home. You arrange a ride, and you rest the remainder of the day.
- Treatments are more frequent at first, then spaced out based on how you respond.
The monitoring is not a warning sign. It is the safeguard that lets a powerful, fast-acting medication be used responsibly.
Who it tends to be for
Esketamine is generally considered when a person has already tried other antidepressants without enough relief. It is not usually a first step, and it is not right for everyone. A clinician will review your medical history, other medications, and blood pressure before recommending it. People with certain cardiovascular conditions, for example, may not be candidates.
It helps some people, not all
Esketamine has helped people who had lost hope in treatment, and that is worth saying plainly. It is also true that it does not work for everyone, and that response has to be weighed against time, cost, and the commitment of frequent visits. A good clinician will talk through both sides rather than sell you on it.
Cost and coverage
Because esketamine is an FDA-approved treatment delivered in a clinical setting, many insurance plans cover it, though coverage, prior authorization, and out-of-pocket costs vary widely. The practical move is to ask a certified provider to check your specific benefits before you commit. Our recommended provider, for example, accepts most insurance including MO HealthNet for eligible Missouri patients.

None of the reading here is a substitute for talking to a licensed clinician who knows your history.
The bottom line
If you have tried the standard steps and depression still has its grip on you, esketamine is a real, mainstream option to ask about, not a last resort to be ashamed of. Bring it up with a clinician, ask whether you are a candidate, and let the supervised structure do its job.
