Spravato vs Ketamine: Choosing the Best Depression Relief

You've tried two, maybe three antidepressants. Each time, you waited weeks hoping this one would finally work. Now you're researching ketamine-based treatments and running into confusing terminology: Spravato, esketamine, IV ketamine, sublingual ketamine. Which one actually makes sense for your situation?

About one-third of people with major depression don't respond to standard medications. If you're among them, understanding the differences between these options matters.

Your choice comes down to three factors: insurance coverage, time commitment, and how quickly you need relief. Spravato requires clinic visits but is often covered by insurance. IV ketamine works faster but costs $400–800 per session out-of-pocket. At-home sublingual ketamine through providers like Innerwell offers convenience with integrated therapeutic support, starting at $54 per session with insurance.

What Is Spravato?

Spravato is the brand name for esketamine, an FDA-approved nasal spray for treatment-resistant depression. The FDA approved it on March 5, 2019. It was the first NMDA receptor antagonist authorized specifically for depression treatment.

Spravato has two approved uses: treatment-resistant depression in adults (typically defined as not responding to at least two adequate antidepressant trials) who may take it as monotherapy or with an oral antidepressant, and depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior, in conjunction with an oral antidepressant.

Because of its potential for misuse, Spravato carries Schedule III classification. You can only receive it at certified healthcare facilities enrolled in the federal REMS program. You cannot take it at home.

What Is Ketamine for Depression?

Ketamine is an FDA-approved anesthetic that doctors prescribe off-label for depression. Research shows response rates of 50–70% in treatment-resistant depression following a single low-dose IV infusion, with symptom relief occurring as early as two hours.

Intravenous (IV) infusion delivers ketamine directly into your bloodstream. The standard protocol involves 0.5 mg/kg infusion over 40 minutes, typically six infusions over two to three weeks. IV infusion has the most extensive research support.

Sublingual/oral administration involves dissolving ketamine under your tongue. Your liver metabolizes much of the medication before it reaches your bloodstream, so higher doses are needed compared to IV administration. Sublingual ketamine is used primarily for maintenance or home-based protocols through telehealth providers.

How Do They Work Differently?

Both Spravato and ketamine target NMDA receptors and glutamate signaling in the brain. Traditional antidepressants work on serotonin, norepinephrine, or dopamine and typically take four to six weeks to show effects. Ketamine-based treatments work through a fundamentally different mechanism.

The chemical distinction matters. Spravato contains only esketamine (the S-enantiomer), while IV ketamine is racemic, containing equal parts of both S-ketamine and R-ketamine molecules. Preclinical research suggests the R-ketamine component may contribute to longer-lasting effects with fewer dissociative side effects, though human evidence is still emerging.

Both medications promote neuroplasticity, your brain's ability to form new neural connections. The neuroplasticity window creates an opportunity where your brain becomes more capable of breaking entrenched patterns that depression reinforces. The medication opens a door; therapy helps you walk through it.

Why does speed matter? According to the McLean study, the first head-to-head comparison, IV ketamine showed improvement immediately after the first treatment, while Spravato showed significant improvement after the second treatment. When you've been experiencing symptoms for months or years, even a few days matters.

Comparing Your Options

How Do Access, Cost, and Risks Compare?

Access and Time Commitment

Spravato requires the highest ongoing commitment: eight clinic visits during the first month, each lasting 1.5–3 hours including mandatory observation. In one long-term continuation study, about 76% of patients who responded to esketamine remained in maintenance treatment for two years or longer, with depressive symptoms generally staying improved.

IV ketamine involves fewer initial sessions (typically six infusions over two to three weeks) with maintenance frequency varying based on individual response, often monthly.

At-home ketamine eliminates travel time entirely. Treatment happens in your own space. Unlike Spravato's two-hour observation requirement, at-home protocols involve telehealth check-ins rather than in-person monitoring.

Cost Reality

Safety Profiles

Both Spravato and ketamine share similar side effects because they work through the same mechanism:

• Dizziness (33.9%)
• Nausea (24.8–33.6%)
• Headache (36.9%)
• Dissociation (25.5%)

Dissociation (feeling temporarily detached from your surroundings) occurs during treatment and typically resolves within the observation period, though experiences can vary. Your blood pressure will be checked before and after each session, as both treatments cause temporary increases.

Contraindications include aneurysmal vascular disease, history of intracerebral hemorrhage, and hypersensitivity to ketamine or esketamine. Pregnancy carries a major warning due to embryo-fetal toxicity risk, with recommendations to avoid use. Review the full prescribing information with your provider before starting treatment.

What Improvement Actually Looks Like

Depression distorts your sense of what's possible. So what should you watch for once treatment begins?

People often notice changes before their mood fully lifts. The first shift is frequently described as the "heavy blanket" sensation easing: that crushing weight that makes getting out of bed feel impossible. Many report being able to imagine a positive future for the first time in months, even if they don't feel happy yet.

Energy and motivation often improve before emotional symptoms resolve. You might find yourself doing small tasks you'd been avoiding, not because you feel better, but because the paralysis has loosened. Sleep improvements frequently occur early in treatment, and better sleep creates a foundation for other gains.

The dissociation you experience during treatment is temporary and distinct from improvement; it's part of the process, not the result. Most people see meaningful improvement within four to six sessions, though some notice changes after their very first treatment.

Which Is Right for You?

Spravato may make sense if:

• Your insurance covers it and you can commit to eight clinic visits over the first month, then ongoing visits potentially for two or more years
• You value FDA approval and standardized safety protocols
• You're willing to continue taking an oral antidepressant alongside Spravato

The time commitment is substantial. If eight clinic visits in the first month feels unsustainable, completion rates may suffer.

IV ketamine may be better if:

• You need immediate symptom relief after your first treatment
• You're paying out-of-pocket regardless of treatment choice
• Your area has established ketamine infusion clinics

Costs add up quickly. Six initial infusions at $400–800 each means $2,400–$4,800 before maintenance begins.

At-home ketamine may be ideal if:

• Clinic visits create significant barriers (work schedules, childcare, distance)
• You want therapeutic support integrated into treatment
• You value the privacy and comfort of your own space

Watch for: Any program that skips mental health follow-up, promises permanent cures, or lacks proper supervision isn't prioritizing your safety.

How Innerwell's Approach Works

What does treatment actually look like? And can you access it without rearranging your life around clinic visits?

Innerwell delivers at-home ketamine therapy paired with licensed psychotherapist support. This isn't ketamine dropped off with minimal supervision. It's a comprehensive program built around the idea that the therapeutic relationship matters as much as the medicine.

Phase 1: Evaluation. A virtual psychiatric assessment by licensed providers (Master's or Doctoral level) determines whether ketamine is right for you, reviews your medical history and current medications, and creates a personalized protocol.

Phase 2: Delivery. Sublingual ketamine tablets ship securely to your door with dosing instructions and direct clinician access through secure messaging.

Phase 3: Preparation and integration. Before your first session, you'll work with a licensed psychotherapist who helps you prepare, set intentions, and understand what to expect. After each session, integration therapy helps you process insights and apply them to lasting change.

Phase 4: Ongoing monitoring. Your care team tracks progress continuously, adjusting protocols based on your response. Regular check-ins and secure messaging keep you connected to clinical support.

Evidence suggests ketamine therapy produces better outcomes when combined with psychotherapy. The medication creates a window of neuroplasticity: a period when your brain is more receptive to change. Without therapeutic guidance, that window may close before meaningful patterns shift.

In Innerwell's internal outcomes tracking, people report a 69% reduction in depression symptoms and 60% reduction in anxiety symptoms after 10 weeks. 87% see improvement within four weeks. Average satisfaction ratings reach 4.7 out of 5.

Making Your Decision

Spravato offers FDA approval and insurance coverage but demands significant clinic time: eight visits in the first month alone. IV ketamine may work faster but costs $400–800 per session out-of-pocket. At-home ketamine through Innerwell combines convenience with integrated therapeutic support that clinic-based treatments often lack.

There's no universally "best" option. The right treatment is the one you can actually access, afford, and sustain long enough to see results. If you've been stuck in the antidepressant trial-and-error cycle, ketamine-based treatments offer a fundamentally different approach.

Frequently Asked Questions

What does dissociation during ketamine treatment feel like?

Dissociation involves temporary feelings of detachment from your body or surroundings. Things may look or sound different; time may seem to move faster or slower. Effects typically peak within 40 minutes and resolve within 1.5–3 hours. Most people describe the experience as tolerable, especially knowing it's temporary. Learn more about what ketamine feels like.

How long will I need to continue ketamine treatment?

Treatment duration varies significantly. After a single ketamine infusion, effects typically last 3–7 days; repeated infusions extend benefit to 18–19 days. Most people need ongoing maintenance, though frequency decreases over time. Your care team will help determine the right schedule based on your symptom patterns. Read more about treatment duration.

Is at-home ketamine as effective as clinic-based treatment?

At-home sublingual ketamine has less peer-reviewed research than IV ketamine or Spravato. However, the therapeutic support integrated into at-home programs may improve outcomes; several studies suggest ketamine works best when combined with psychotherapy. The convenience also improves adherence: you're more likely to complete treatment you can fit into your life.

Will my employer or insurance company find out I'm using ketamine?

Spravato treatment appears on insurance claims. IV ketamine paid out-of-pocket creates no insurance record. HIPAA generally prevents health plans and providers from sharing your protected health information with employers without your authorization, except in limited, legally defined situations. If privacy concerns you, discuss payment options with your provider before starting treatment. Check state regulations for specific rules.
