IV Ketamine vs Spravato: What’s the Difference?

What Each One Is
IV Ketamine
Ketamine has been FDA approved as an anesthetic since 1970. Its use for depression, PTSD, anxiety, and chronic pain is considered off-label and is supported by peer-reviewed research dating back to the early 2000s. IV ketamine is the form most studied in mental health research.
Spravato (esketamine)
A chemically related compound, one of the two mirror-image molecules that make up ketamine. The FDA approved Spravato in 2019 for treatment-resistant depression, administered as a nasal spray at REMS-certified providers under supervision. The REMS program (Risk Evaluation and Mitigation Strategy) requires patients to remain at the clinic for 2 hours after each dose.
Side-by-Side Comparison
Delivery
- IV ketamine is delivered through a small IV catheter directly into the bloodstream. This produces predictable blood concentrations and allows the clinician to adjust the infusion rate during the session if needed.
- Spravato is delivered as a nasal spray. The patient self-administers under provider supervision.
FDA Status
- IV ketamine is FDA approved as an anesthetic. Use for depression and other mental health conditions is considered off-label. Off-label prescribing is a normal and legal part of medical practice, particularly when supported by peer-reviewed evidence.
- Spravato is FDA approved specifically for adults with treatment-resistant depression. This is the formal regulatory recognition of ketamine-related compounds in mental health treatment.
What Each Treats
- IV ketamine is used for depression, treatment-resistant depression, PTSD, anxiety, and chronic pain.
- Spravato is FDA approved only for treatment-resistant depression. It is not approved for PTSD, anxiety, or chronic pain (though research continues).
Dosing Flexibility
- IV ketamine dosing is individualized by the clinician based on body weight, prior response, and clinical judgment. The infusion can be adjusted in real time.
- Spravato is a fixed-dose nasal spray (56 mg or 84 mg). Less individualization.
Session Logistics
- IV ketamine at Hydrate Asheville is a 40 to 60 minute infusion plus 30 minutes recovery. Total time at clinic: 1.5 to 2 hours.
- Spravato is a fixed nasal spray protocol plus a 2-hour REMS-mandated monitoring window. Total time at REMS clinic: about 3 hours per session.
Where You Can Get It
- IV ketamine is offered at independent ketamine clinics, including Hydrate Medical Asheville.
- Spravato is restricted to REMS-certified providers, mostly hospital systems and certain large practices.
Insurance and Cost
- IV ketamine is typically not covered by insurance. Patients pay out of pocket. HSA and FSA accepted where eligible.
- Spravato is sometimes covered by insurance, especially for patients with treatment-resistant depression who have failed multiple antidepressants. Copays and out-of-pocket costs vary widely.
Which One Is the Better Fit?
When IV Ketamine Fits Better
- You have depression, PTSD, anxiety, or chronic pain (Spravato is only approved for treatment-resistant depression)
- You want individualized dosing based on your specific case
- You prefer a shorter session (1.5 to 2 hours vs. 3+ hours for Spravato)
- You do not have access to a REMS-certified Spravato provider nearby
- You want the option of KAP (ketamine-assisted psychotherapy), which Spravato does not support
When Spravato Fits Better
- You have treatment-resistant depression specifically
- You have insurance coverage for Spravato and want to minimize out-of-pocket cost
- A REMS-certified provider is accessible to you
- You have a strong preference for nasal delivery over IV
- Your psychiatrist has specifically recommended Spravato
Can I try both? Yes. Some patients work with both treatments, sometimes in sequence. Discuss with your psychiatrist or our clinical team during evaluation.

Frequently Asked Questions
Is one safer than the other?
Both have similar safety profiles in monitored clinical settings. Both can cause dissociation, mild blood pressure elevation, and nausea during the session. The REMS program for Spravato exists to ensure monitoring; we provide the same monitoring for IV ketamine.
Does insurance cover either?
Spravato is sometimes covered. IV ketamine is rarely covered.
Is one more effective?
Direct head-to-head trials are limited. Both work through similar receptor mechanisms (NMDA antagonism). Individual response varies regardless of formulation.
Can I switch from Spravato to IV ketamine?
Yes. Many patients do, particularly when looking for individualized dosing or treatment of conditions beyond depression.
Why does Hydrate Asheville offer IV and not Spravato?
We focus on IV ketamine and KAP. Spravato requires REMS certification which is a separate regulatory program. Many ketamine-focused clinics make this same choice.
