Ketamine vs. Spravato: What's the Difference?

Short answer: IV ketamine and Spravato are both forms of ketamine used for depression, but they are not the same. They differ in chemistry, how they are delivered, their FDA status, how insurance treats them, and the logistics of treatment. IV ketamine is flexible, fast-acting, off-label, and usually self-pay. Spravato is a standardized, FDA-approved nasal spray that insurance often covers. Neither is universally better. Here is how they compare.

They are chemical cousins

Ketamine is made of two mirror-image molecules, called R and S. Most IV ketamine is racemic, meaning it contains both. Spravato is esketamine, which uses only the S part. They work through similar mechanisms in the brain, but that difference in composition, along with how each is delivered, drives most of the practical distinctions below.

How they are given

This is the most noticeable difference. IV ketamine is delivered as an intravenous infusion by a clinician, usually over about 40 minutes, with the dose adjustable in real time to keep you comfortable. Spravato is a nasal spray you self-administer in the clinic under supervision, at a fixed dose, followed by a required two-hour monitoring period before you can leave. Both happen in a medical setting; the experience and the timing differ.

FDA approval, and why it matters

Spravato is FDA-approved specifically for treatment-resistant depression and for major depressive disorder with acute suicidal thoughts. IV ketamine is FDA-approved as an anesthetic, so its use for depression is off-label. This is not a statement about how well IV ketamine works; it is about how it is regulated, and it has big downstream effects on insurance.

Insurance and cost

Because Spravato is FDA-approved for depression, commercial insurance and Medicare often cover it for eligible patients. IV ketamine, being off-label, is usually self-pay, commonly a few hundred dollars per session, though many clinics offer course pricing and financing. There is also a logistics difference: IV ketamine tends to require far fewer visits over a year than Spravato, which involves frequent, closely scheduled appointments especially at the start. Our guide to whether insurance covers ketamine digs into the coverage side.

Effectiveness

Here is the reassuring part: head-to-head, the two are broadly comparable in effectiveness and side effects. Some observational data suggest IV ketamine may achieve remission in fewer sessions and hold between treatments a bit longer, thanks in part to its flexible dosing. Spravato brings a standardized protocol and strong relapse-prevention data within an FDA-approved framework. The honest takeaway is that neither wins for everyone; the right choice depends on the person.

Which is right for you?

A few things tend to guide the decision. If insurance coverage is a priority, Spravato has the clear advantage. If you value flexible dosing, fewer visits, and a rapid, adjustable infusion, IV ketamine may suit you better. Your history, your response, and your logistics all matter, which is why this is a conversation to have with a knowledgeable provider rather than a decision to make from a chart.

At Ketamine Uplift

We currently offer IV ketamine therapy for depression and related conditions, and Spravato is almost here.

The bottom line

IV ketamine and Spravato are related but distinct: IV ketamine is a flexible, fast, off-label infusion usually paid out of pocket, while Spravato is a standardized, FDA-approved nasal spray that insurance often covers but requires more frequent visits. Effectiveness is similar, so the best choice comes down to your situation. If you would like help thinking it through, call us at (310) 280-4440.

Frequently asked questions

What is the difference between ketamine and Spravato?
IV ketamine is racemic ketamine given as a flexible, clinician-controlled infusion; it is off-label and usually self-pay. Spravato is esketamine, a fixed-dose nasal spray, FDA-approved for treatment-resistant depression and often covered by insurance. Effectiveness is broadly comparable.

Is Spravato the same as ketamine?
They are closely related. Spravato uses only the S part of the ketamine molecule, while most IV ketamine contains both R and S. Similar mechanisms, different delivery, approval, and cost.

Is IV ketamine or Spravato more effective?
Comparisons generally find similar effectiveness. Some data suggest IV ketamine may reach remission in fewer sessions with more durable effects, while Spravato offers a standardized, insurance-accessible path. Neither is best for everyone.

Does Ketamine Uplift offer both?
We currently offer IV ketamine, and Spravato is almost here; we are in the final stage of credentialing to add it. Once it is available, we can help you choose the option that best fits your needs and coverage.
