Spravato vs. Ketamine Infusions: What's the Difference?

Spravato (esketamine) is a nasal spray with FDA approval for certain kinds of depression. You take it under close supervision at a certified clinic, and there is a defined path to insurance coverage. Ketamine infusions rely on the original IV form of ketamine — FDA-approved as an anesthetic, prescribed off-label for mood conditions — and patients usually pay out of pocket. Both trace back to the same parent molecule; where they really diverge is approval status, supervision rules, how each is administered, and cost.

Are Spravato and ketamine infusions the same thing?

Close — but not quite. Chemists describe ketamine as a chiral molecule, meaning it exists in two mirror-image forms — the way a left hand mirrors a right. Spravato contains just the "S" form, called esketamine. Traditional ketamine infusions use racemic ketamine, a mix of both forms, delivered through an IV line.

Both work on the brain's glutamate system — a different pathway than the one most standard antidepressants target — and for some people, either one can shift mood noticeably in relatively little time. Still, "same family" doesn't mean "same treatment." How they're regulated, how they're given, who supervises them, who pays for them — the two differ on all of it, and those differences shape what your experience will actually look like.

Is Spravato FDA-approved? What about ketamine infusions?

Spravato is FDA-approved for specific psychiatric uses. In 2019, the FDA approved it, taken together with an oral antidepressant, for treatment-resistant depression — meaning depression that has not improved enough after adequate trials of at least two antidepressants. In 2020, the approval was expanded to include depressive symptoms in adults with major depressive disorder who have acute suicidal thoughts or behavior. In 2025, the FDA also approved Spravato as a standalone treatment for treatment-resistant depression, so an oral antidepressant is no longer always required alongside it.

Ketamine itself has been FDA-approved for decades — but as an anesthetic, not as a psychiatric medication. When clinics offer ketamine infusions for depression or other mental health conditions, that use is off-label. Off-label prescribing is legal and common throughout medicine. It simply means the FDA has not formally reviewed and approved the evidence for that particular use. The practical result is fewer built-in guardrails and less standardization, which matters most when we get to supervision and insurance below.

What does REMS supervision mean for Spravato?

Because Spravato can cause temporary sedation, dissociation (a dreamlike or detached feeling), and elevated blood pressure, and because ketamine-type medications have misuse potential, the FDA requires Spravato to be dispensed under a Risk Evaluation and Mitigation Strategy, or REMS. In plain terms, that means:

• Spravato is given only at certified treatment centers. You never take it home.
• You administer the nasal spray yourself, but a trained staff member observes you do it.
• You are monitored in the office for at least two hours afterward, including blood pressure checks.
• You cannot drive until the next day, after a restful night's sleep, so you'll need someone to take you home.

Ketamine infusion clinics are not governed by a REMS program. Reputable clinics monitor vital signs and have emergency protocols, but there is no single federal framework that requires it, and standards genuinely vary from clinic to clinic. If you're considering infusions, it's fair — and wise — to ask any clinic exactly how you'll be monitored and by whom.

How is each treatment actually given?

Spravato comes as single-use nasal spray devices. At your appointment, you spray the medication into your own nose while a staff member watches, then rest in a comfortable chair for the two-hour monitoring period. Under the FDA label, a common schedule is twice-weekly sessions for the first four weeks, then weekly sessions, and then weekly or every-other-week sessions depending on how you respond. Your prescriber sets the exact plan with you.

Ketamine infusions involve an IV placed in your arm, with the medication delivered slowly — often over roughly forty minutes to an hour — followed by a recovery period. Many clinics start with a series of infusions over a few weeks and then offer maintenance "booster" infusions, but because there is no FDA label for this use, protocols differ by clinic.

With either option, you may feel dissociated, drowsy, or a little unsteady afterward, so plan for a ride home either way.

Does insurance cover Spravato or ketamine infusions?

This is often the biggest practical difference for patients and families.

Because Spravato is FDA-approved, there is a defined path to getting it covered. Plans that cover it usually require prior authorization — your clinician documents your diagnosis and the antidepressants you've already tried — and coverage isn't automatic. Whether and how much your specific plan pays varies by plan and state, so it's worth confirming with your insurer before you start. You can also check whether your plan is among the insurance plans we accept.

Because infusions are off-label for depression, most insurers will not pay for the medication or its administration for psychiatric use. Some plans reimburse small portions, such as the office visit itself, but in most cases ketamine infusions are self-pay, charged per infusion — and a full series plus maintenance boosters can add up quickly. If you're comparing costs, ask any infusion clinic for the total price of the recommended series in writing, not just the per-session rate.

How does qualifying work — and how is it different for each?

The clearest difference is that Spravato has defined criteria and infusions don't. Spravato's approval covers adults with treatment-resistant depression — generally meaning you've tried at least two antidepressants at an adequate dose and duration without enough relief — and adults with major depressive disorder who are experiencing acute suicidal thoughts or behavior, as part of a broader plan of care for depression. If you're wondering whether your own history fits those criteria, our Spravato treatment page walks through the evaluation in more detail. Spravato is not approved for bipolar depression, so if you've been diagnosed with or suspect bipolar disorder, tell your clinician; the safest treatment path looks different.

Because ketamine infusions are off-label, there is no single qualification standard — each clinic sets its own. Some infusion clinics focus on depression; others also treat chronic pain or other conditions, and the depth of psychiatric screening varies. Sensible questions to ask: Who performs the psychiatric evaluation? Is medical staff present during the infusion? Will the clinic coordinate with your existing psychiatrist?

How do I decide which one is right for me?

This isn't a decision to make alone, and it doesn't have to be. The right choice depends on your diagnosis, what you've already tried, your medical history, your insurance, and honestly, your logistics — how far you can travel and how often. For many people with treatment-resistant depression and health insurance, Spravato is the more accessible and more structured option; for others, an infusion clinic may be part of the conversation.

A psychiatric clinician can walk through it with you. You can meet the psychiatrists and nurse practitioners on our team, and when you're ready, book a first appointment to talk through which option fits your situation.

Frequently asked questions

Is Spravato just ketamine in a nasal spray?

Not exactly. Spravato contains esketamine, one of ketamine's two mirror-image forms, while infusions use racemic ketamine, which contains both. They're close relatives with different regulatory status, delivery methods, and supervision requirements.

Which works faster, Spravato or ketamine infusions?

Both can act more quickly than standard antidepressants for some people — sometimes within days rather than weeks. Individual responses vary widely, though, and neither option works for everyone. There isn't enough head-to-head research to say one is reliably faster than the other.

Can I drive myself home after a session?

No. Spravato's REMS rules prohibit driving until the next day, after a restful night's sleep, and responsible infusion clinics require a ride home as well. Arrange transportation before your first appointment.

How long does a Spravato appointment take?

Plan on roughly two and a half hours: a brief check-in, the nasal spray itself, and then the required two-hour monitoring period with blood pressure checks before you're cleared to leave.

Does Spravato treat anxiety, PTSD, or OCD?

Spravato's FDA approvals are specific to depression. Researchers are studying ketamine-type medications for other conditions — trauma and PTSD among them — but those uses remain off-label. If you're struggling with anxiety, trauma, or obsessive-compulsive symptoms, a clinician can walk you through the established treatment options for each.

Do I have to stop my current antidepressant to start Spravato?

Usually not. Spravato was originally approved to be taken alongside an oral antidepressant, and since 2025 it can also be prescribed on its own. Your prescriber will decide what combination makes sense for you — don't stop any medication without talking to them first.

Is ketamine addictive?

Ketamine-type medications carry misuse potential, which is one reason the FDA requires the REMS program for Spravato. In a supervised setting, the medication is stored, administered, and monitored by the clinic — you never take it home. If you have a history of substance use, bring it up honestly; it doesn't automatically disqualify you, but it shapes the safest plan.

What if I'm in crisis right now?

If you are having thoughts of suicide or self-harm, or you're worried about someone who is, call or text 988 to reach the Suicide & Crisis Lifeline, available 24/7. If you or someone else is in immediate danger, call 911 or go to the nearest emergency room.
