If you’ve spent time researching ketamine therapy, you’ve probably run into the same question most patients ask: “What’s the difference between IV infusion and SPRAVATO — and which one is right for me?”
The honest answer is: it depends on your diagnosis, your insurance coverage, and a conversation with a physician who knows your history. And that’s exactly what this guide is for.
At Charleston Ketamine Center, Dr. Richard L. Bowen has guided thousands of patients through this decision. Below is a straight-talk breakdown of how these two treatments compare — including the clinical evidence, the costs, and the factors that actually drive the choice.
How Both Treatments Work
Ketamine IV infusion therapy and SPRAVATO® (esketamine) are both forms of ketamine-based treatment, and they share the same fundamental mechanism: they target NMDA receptors in the brain. This is a completely different pathway than traditional antidepressants, which primarily affect serotonin.
Because ketamine works on the brain’s glutamate system, it can reach patients who haven’t responded to SSRIs, SNRIs, or other standard psychiatric medications. And unlike most antidepressants — which can take weeks to produce results — ketamine-based treatments may begin working within hours to days for some patients.
But the two treatments differ significantly in how they’re delivered, who they’re approved for, and how they’re covered by insurance. Understanding those differences is the first step in making an informed decision.
Ketamine IV Infusion Therapy: Clinical Evidence and Flexible Reach
IV infusion therapy delivers ketamine directly into the bloodstream through an intravenous drip. This method gives your physician precise, real-time control over dosing — which is one reason it carries the deepest clinical evidence of any ketamine treatment available, with research published by Mayo Clinic, Cleveland Clinic, and the Journal of Clinical Psychiatry.
What to Expect at CKC
At Charleston Ketamine Center, the standard protocol for depression and anxiety is six one-hour infusions over two weeks, provided in a private, calm, monitored setting. This is usually followed by another single one-hour infusion two weeks later. At this time, most patients are started on low-dose at-home Ketamine lozenges. With the lozenges, patients then get infusions on a monthly basis for the next few months, then on an as needed basis thereafter.
For chronic pain conditions — including Complex Regional Pain Syndrome (CRPS) and peripheral neuropathy — treatment involves four-hour infusions on four consecutive days, with further sessions based on your individual response.
During an infusion, most patients experience a calm but unique state. Full cognitive function typically returns within 20 to 30 minutes after the session ends. You will need a driver, as motor function may take longer to fully normalize.
Conditions IV Infusion May Help
- Treatment-resistant depression (TRD) and major depressive disorder
- Anxiety disorders, including PTSD
- Chronic nerve pain, CRPS, and peripheral neuropathy
Pricing at CKC:Depression and anxiety infusions are $400 per session. Pain infusions are $850 per four-hour session. Advance Care Card and CareCredit financing are available. |
SPRAVATO®: FDA-Approved and Insurance-Covered
SPRAVATO is the brand name for esketamine, a nasal spray form of ketamine developed by Janssen Pharmaceuticals. Unlike IV ketamine — which is used off-label for depression — SPRAVATO received FDA approval specifically for treatment-resistant depression (TRD) and for major depressive disorder (MDD) with active suicidal ideation.
That FDA approval matters for a very practical reason: insurance covers it. Most major insurance plans cover SPRAVATO for patients with qualifying diagnoses — making it accessible to people for whom out-of-pocket IV infusion costs are prohibitive.
What to Expect With SPRAVATO
SPRAVATO is available only through clinics certified in the FDA’s REMS (Risk Evaluation and Mitigation Strategy) program. This requires careful patient screening, structured dosing protocols, and in-office monitoring at every session — no exceptions.
Each session involves self-administering the nasal spray under physician supervision, followed by a required two-hour monitoring period in the office.
Insurance note:Coverage varies by provider and policy. CKC’s team can assist with benefit verification and prior authorization before treatment begins. |
Which Is More Effective? The Honest Answer.
We believe patients deserve a straight answer: according to a 2021 peer-reviewed study, IV ketamine is clinically more effective than SPRAVATO for treating depression.
That’s an important fact — and it’s one we share with every patient, because physician-guided care means being honest about what the evidence actually shows.
That said, SPRAVATO still provides meaningful benefits for many people living with treatment-resistant depression. And for patients who cannot access IV ketamine due to cost, SPRAVATO may be the treatment that changes their life. Effectiveness is not only about which drug performs better in a study — it’s about which treatment a patient can actually access, afford, and complete.
Risks and Considerations
As with any medical treatment, both options carry risks that should be discussed with your physician before starting.
- Both treatments can cause temporary dissociation, dizziness, nausea, or changes in blood pressure during the session. These are closely monitored at CKC.
- SPRAVATO’s required two-hour monitoring period exists specifically because of the risk of sedation and dissociation — patients cannot drive after any session.
- IV infusion requires a driver or using a ride share service, as motor function may not fully recover within the standard post-infusion window.
- Neither treatment is appropriate for patients with certain cardiovascular conditions, uncontrolled hypertension, or a history of psychosis. Dr. Bowen screens carefully for these during the initial consultation.
This is one of the most important reasons to seek ketamine treatment from a physician-supervised clinic: the risks that exist can be effectively managed when a qualified medical team is overseeing every step.
When to Talk to a Physician
Ketamine therapy may be worth discussing with a physician if you:
- Are suffering from depression or anxiety and want to get rapid relief
- Have tried two or more antidepressants or psychiatric medications without lasting relief
- Are living with chronic nerve pain, CRPS, or neuropathy that hasn’t responded to standard treatments
- Are managing PTSD, severe anxiety, or postpartum depression that affects daily functioning
- Have concerns about your current treatment plan and want to explore evidence-based alternatives
If you are currently in crisis, please contact the Suicide and Crisis Lifeline by calling or texting 988 before pursuing any elective treatment options.
The Right Choice Starts With a Physician Conversation
There is no universal answer to whether IV infusion or SPRAVATO is the right choice — and anyone who tells you otherwise isn’t giving you the full picture. The right treatment depends on your diagnosis, your history with other medications, your insurance situation, and your goals for care.
Some patients are ideal candidates for SPRAVATO because insurance removes a major financial barrier. Others — particularly those with complex pain conditions or a history of failed psychiatric treatments — may see better outcomes with IV infusion therapy. Some patients use both, at different points in their treatment journey.
