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

If you've decided ketamine therapy might help your depression, you've probably hit a fork in the road: IV ketamine or Spravato? They sound like two versions of the same thing, and in a sense they are. But the way each one is regulated, priced, and covered by insurance is different enough that it often decides which one you can actually get.

Here's the short version. Spravato is the FDA-approved nasal spray that most insurance plans cover for treatment-resistant depression. IV ketamine is the off-label infusion that usually costs more out of pocket but treats a wider range of conditions and gives your provider more control over the dose. Which one fits you comes down to your diagnosis, your budget, and what you can access near you.

To write this, we pulled real pricing data from the hundreds of ketamine clinics listed in our directory, so the cost numbers below reflect what clinics actually charge, not vague estimates. Below we break down how the two compare on cost, insurance, results, and what each one feels like, so you can walk into a consultation knowing which questions to ask.

IV Ketamine vs. Spravato: The Short Answer

Spravato (esketamine) is an FDA-approved nasal spray covered by most insurance plans for treatment-resistant depression. IV ketamine is racemic ketamine delivered through an infusion, used off-label for depression and several other conditions, and it's usually self-pay.

That single regulatory difference drives almost everything else. Because Spravato has FDA approval, insurance treats it like any other covered medication. Because IV ketamine is off-label, it sits outside most insurance coverage, which changes what you pay and how you access it.

Quick Comparison: IV Ketamine vs. Spravato at a Glance

Before we get into the details, here's how the two stack up side by side. This table covers the differences that matter most when you're choosing.

Factor	IV Ketamine	Spravato (Esketamine)
Active molecule	Racemic ketamine	Esketamine
How it's given	IV infusion	Nasal spray
FDA status	Off-label	FDA-approved for TRD and MDD with suicidal ideation
Typical cost per session	$350 to $600 self-pay	List price higher, but often a copay after insurance
Insurance coverage	Rarely covered	Covered by most plans
Session length	About 40 to 60 minutes	About 2 hours
Monitoring	Nurse-monitored throughout	Two-hour observation required
Conditions treated	Depression, anxiety, PTSD, OCD, bipolar depression, chronic pain	Treatment-resistant depression, MDD with suicidal ideation
Dosing flexibility	High, provider adjusts dose and rate	Fixed approved doses
Ride home needed	Yes	Yes

Keep this table in mind as we go, because most of the decision comes down to trading flexibility and breadth (IV) against approval and coverage (Spravato).

What Is IV Ketamine Therapy?

IV ketamine is racemic ketamine delivered straight into your bloodstream through an infusion, with a nurse or provider monitoring you the whole time. A typical infusion runs about 40 to 60 minutes, and most people start with a series of six infusions over two to three weeks before moving to occasional maintenance sessions.

The biggest practical feature is dose control. Because the medication goes in through an IV, your provider can adjust the dose and the rate in real time based on how you respond. That flexibility is part of why clinics use IV ketamine off-label for more than just depression, including anxiety, PTSD, OCD, bipolar depression, and certain chronic pain conditions.

The word "off-label" sounds alarming, but it does not mean experimental or unregulated. Ketamine has been an FDA-approved anesthetic since the 1970s, and doctors are allowed to prescribe approved medications for other uses when the evidence supports it. You can read more about the basics in our guide on what ketamine therapy is and how it works.

What Is Spravato (Esketamine)?

Spravato is the brand name for esketamine, a nasal spray version derived from ketamine. The FDA approved it in 2019 for treatment-resistant depression and expanded that approval in 2020 to cover major depressive disorder with acute suicidal thoughts or actions. It's taken alongside an oral antidepressant, not on its own.

You self-administer the spray in the clinic, but you don't take it home. Spravato falls under an FDA safety program called REMS, which requires you to stay for a two-hour monitored observation period after each dose. A provider checks your blood pressure and watches for side effects during that window, and you'll need someone to drive you home afterward.

That structure makes Spravato more standardized than IV ketamine. The doses are fixed and FDA-studied, the protocol is consistent from clinic to clinic, and the approval is what allows insurance to cover it.

IV Ketamine vs. Spravato: Cost Compared

Cost is where these two treatments split the most, and it's usually the deciding factor. The sticker prices can be misleading, so it helps to separate what a treatment lists for from what you actually pay.

How Much IV Ketamine Costs

Across the clinics in our directory, a single IV ketamine infusion typically runs between $350 and $600, with many clinics landing around $400 to $450 per session. Since the standard starting protocol is six infusions, the upfront cost of an induction series often falls in the $2,100 to $3,600 range.

Most clinics treat IV ketamine as self-pay because insurance rarely covers it. Some offer package pricing that brings the per-infusion cost down if you pay for the full series at once.

How Much Spravato Costs

Spravato's list price per session is higher than a single IV infusion, but that number is misleading because most patients never pay it in full. When insurance covers Spravato, your real cost is usually a copay, which can range from very little to a moderate amount depending on your plan.

Spravato also requires more sessions early on. The typical schedule is twice a week for the first four weeks, then weekly, then every one to two weeks for maintenance, so the frequency is higher even when the per-session cost to you is lower.

The Real Out-of-Pocket Difference

Here's the honest takeaway: Spravato has the higher list price, but insurance usually makes it far cheaper than self-pay IV ketamine. For a lot of patients with treatment-resistant depression, a Spravato copay over several weeks costs less than a single self-pay IV induction series.

If cost is your main concern, this is the gap that matters most. For a full breakdown of pricing across every treatment type, see our guide on how much ketamine therapy costs.

Does Insurance Cover IV Ketamine or Spravato?

Insurance is the flip side of the cost question, and it follows directly from FDA status. One treatment is built for coverage, and the other mostly isn't.

Spravato and Insurance

Because Spravato is FDA-approved, most commercial insurance plans, Medicare, and many Medicaid plans cover it for patients who qualify. Coverage almost always requires prior authorization, which means your provider documents that you've tried other antidepressants without enough relief before the plan approves treatment.

That approval step takes some patience, but clinics that offer Spravato handle it regularly and usually manage the paperwork for you.

IV Ketamine and Insurance

IV ketamine is a different story. Its off-label status means most plans won't cover the infusion itself, so you're typically paying out of pocket.

Some patients recover part of the cost by asking the clinic for a superbill, an itemized receipt you can submit to your insurer for possible out-of-network reimbursement. Approval isn't guaranteed, but it's worth trying if your plan has out-of-network benefits.

How to Get Either One Approved

Getting coverage comes down to documentation and persistence. A few steps make the process smoother:

Gather your treatment history: have a record of the antidepressants you've tried and how they worked, since prior authorization depends on it.
Ask the clinic to handle prior authorization: most Spravato providers do this routinely and know what each insurer wants.
Request a superbill for IV ketamine: even when the treatment isn't covered directly, an out-of-network claim might recoup part of the cost.

Which Works Better, IV Ketamine or Spravato?

This is the question everyone wants a clean answer to, and the honest response is that neither one is universally better. They're both effective for treatment-resistant depression, and the right choice depends on your situation.

What the Research Shows

Both IV ketamine and Spravato have solid evidence behind them for treatment-resistant depression, and both can work within hours to days rather than the weeks oral antidepressants take. Direct head-to-head studies comparing the two are still limited, so there's no definitive proof that one beats the other for the average patient.

Some clinicians find IV ketamine useful for people who didn't respond to Spravato, partly because of how the dosing can be adjusted. That's a clinical observation more than a settled fact, but it's a common reason patients switch.

Why IV's Dosing Flexibility Matters

The main clinical advantage of IV ketamine is control. Your provider can fine-tune the dose and the infusion rate to match how you respond, which can help when a standard dose isn't doing enough.

That flexibility also lets clinics treat conditions beyond depression. If you're dealing with PTSD, OCD, or chronic pain alongside or instead of depression, IV ketamine's broader off-label use can be a better match.

Why Spravato's Standardization Matters

Spravato's strength is the opposite: consistency. The doses are FDA-studied, the protocol is the same everywhere, and the treatment comes with insurance backing and a clear safety framework.

For many people with treatment-resistant depression, that standardized, covered, well-monitored path is exactly what makes treatment realistic to start and stick with.

What Each Treatment Feels Like

Knowing what actually happens in the chair takes a lot of the anxiety out of starting. The two sessions feel different, mostly because of how the medication enters your body.

An IV Ketamine Session Start to Finish

You'll settle into a reclining chair, and a provider will place an IV in your arm. The medication starts working gradually, and over the next 40 to 60 minutes you may feel a floating or dissociative sensation, which is expected and temporary.

A nurse or provider monitors your vital signs the entire time. When the infusion ends, you rest until you feel steady, and then someone drives you home.

A Spravato Session Start to Finish

For Spravato, you spray the medication into your nose yourself, under a provider's supervision. After your dose, you stay in the clinic for a two-hour observation period while staff monitor your blood pressure and watch for side effects like drowsiness or dissociation.

Once the observation window is over and you're feeling clear, you head home with your ride. You can't drive yourself for the rest of the day.

Whichever route you choose, plan for that ride home. Neither IV ketamine nor Spravato lets you drive after a session.

IV Ketamine vs. Spravato: Which Is Right for You?

By now the pattern is clear: the choice depends on your diagnosis, your budget, and what you want out of treatment. These two short profiles can help you see where you land.

IV ketamine may be the better fit in a few specific situations. Consider it if the following sound like you:

You have a condition beyond depression: IV ketamine's off-label use covers PTSD, OCD, bipolar depression, and chronic pain.
You've tried Spravato without enough relief: the adjustable dosing gives your provider another lever to pull.
Cost isn't your main barrier: self-pay pricing is workable for you, or you want maximum dosing flexibility.

Spravato tends to be the better fit for a different set of priorities. Lean toward it if these apply:

You have treatment-resistant depression specifically: that's exactly what Spravato is approved to treat.
You want insurance to cover it: FDA approval is what makes coverage possible.
You prefer a standardized protocol: fixed, FDA-studied doses and a consistent process appeal to you.

One reassuring point: plenty of clinics offer both treatments, so you're not locked in. A provider can start you on one and switch you to the other if your response calls for it.

How to Find a Clinic That Offers IV Ketamine or Spravato

Once you know which route you're leaning toward, the next step is finding a clinic that offers it. There's a built-in quality filter worth knowing about here.

Any clinic that offers Spravato has to be REMS-certified, which means it meets the FDA's requirements for safely administering esketamine. That certification is a useful signal that you're dealing with a legitimate provider rather than an unregulated operation.

Many clinics offer both IV ketamine and Spravato, which gives you room to start with one and adjust later. You can filter our directory by treatment type and location to see verified clinics near you that offer the route you want, along with their pricing and insurance details where available.

Bottom Line

The choice between IV ketamine and Spravato really comes down to two trade-offs. Spravato wins on FDA approval and insurance coverage, which makes it the more affordable and accessible option for most people with treatment-resistant depression. IV ketamine wins on dosing flexibility and the range of conditions it can treat, but you'll usually pay for it out of pocket.

If your main barrier is cost and you have treatment-resistant depression, Spravato is often the practical starting point. If you have a condition beyond depression, or you've already tried Spravato without enough relief, IV ketamine's flexibility may serve you better.

Frequently Asked Questions

Below are quick answers to the questions people ask most when comparing these two treatments.

Is Spravato Just Ketamine?

Not exactly. Spravato is esketamine, a component derived from the ketamine molecule, while IV ketamine uses racemic ketamine, which contains two mirror-image forms. They're closely related but not identical, and they're regulated very differently.

Is IV Ketamine or Spravato Better for Depression?

Both are effective for treatment-resistant depression, and neither is proven better for the average patient. Spravato has FDA approval and insurance coverage, while IV ketamine offers more dosing flexibility, so the better choice depends on your needs and access.

Why Is IV Ketamine Not FDA-Approved?

Ketamine itself is FDA-approved as an anesthetic, but not specifically for depression, so using it that way is off-label. Generic ketamine is inexpensive and hard to patent, which removed much of the financial incentive to fund the large trials FDA approval for depression would require.

Can You Switch From Spravato to IV Ketamine?

Yes, and patients do it in both directions. If one treatment isn't giving you enough relief, a provider can move you to the other, which is one reason many people choose a clinic that offers both.

Is Spravato Cheaper Than IV Ketamine?

Often, yes, once insurance is involved. Spravato has a higher list price, but because most plans cover it, your real cost is usually a copay that comes out lower than self-pay IV ketamine.

Does Insurance Cover IV Ketamine Infusions?

Usually not, because IV ketamine is off-label for depression. Some patients submit a superbill to recover part of the cost through out-of-network benefits, but coverage isn't guaranteed.
