Esketamine, sold under the brand name Spravato, is one of the more talked-about developments in depression care in years. It is also widely misunderstood. It is not a party drug, not a cure, and not something you take home in a bottle. Here is a calm, honest account of what it actually is.
What it is
Esketamine is a medication derived from ketamine, delivered as a nasal spray. The US Food and Drug Administration has approved it, used together with an oral antidepressant, for adults with treatment-resistant depression, and for depressive symptoms in adults with major depression who have acute suicidal thoughts or behavior. It acts on the brain's glutamate system, a different pathway than standard antidepressants, which is part of why it can help some people who have not responded to other medications.
How a session works
Spravato is only given in a certified healthcare setting, never at home. On a treatment day, you self-administer the nasal spray under supervision, then stay to be monitored, typically for about two hours, because it can temporarily raise blood pressure and cause dissociation, a floaty, detached feeling. Because of those effects, you cannot drive afterward and arrange a ride home. Early on, sessions usually happen twice a week, then taper in frequency over time based on how you respond.
The monitoring is not a red flag, it is the safety design. Being observed by trained staff for a couple of hours is exactly what makes a stronger, faster-acting medication reasonable to use. It is a feature of the treatment, not a warning about it.
Who it tends to be for
Esketamine is generally considered when at least a couple of standard antidepressants have not brought enough relief. It is not usually a first medication to try, and it is prescribed and supervised by clinicians who assess whether it fits your history and health. It is one tool among several, weighed against options like TMS and adjustments to other treatment.
The honest version: it helps some people meaningfully, it is not magic, and it is done carefully for a reason.
Honest limits
Esketamine does not work for everyone, and it is not a one-time fix. It requires a real time commitment for the treatment schedule and the monitoring. Common short-term effects include dissociation, dizziness, nausea, and raised blood pressure during the session. It is used within a controlled program precisely because it is a serious medication. Your clinician is the right person to weigh the benefits and risks for your situation.
Coverage and access
Because it is FDA-approved, esketamine is covered by many insurance plans, though coverage and prior-authorization rules vary. A certified provider can check your specific coverage.
