If you're living with treatment-resistant depression, anxiety, or PTSD, you've probably heard about ketamine therapy. But choosing how to access it can be overwhelming. Two of the most popular options in 2026 are Spravato (esketamine nasal spray) and at-home ketamine microdosing through telehealth providers like Kalm Health.
Both approaches use ketamine — but the experience, cost, convenience, and accessibility couldn't be more different. Here's a straightforward comparison to help you decide which might be right for you.
What Is Spravato?
Spravato (esketamine) is an FDA-approved nasal spray manufactured by Janssen/Johnson & Johnson. It's specifically approved for treatment-resistant depression (TRD) and major depressive disorder with suicidal ideation.
-
Administration: Self-administered nasal spray under clinical supervision
-
Setting: Must be done at a certified REMS healthcare facility — you cannot take it home
-
Frequency: Twice weekly for the first month, then weekly or biweekly
-
Monitoring: Required to stay at the clinic for 2+ hours after each dose for observation
-
Insurance: Covered by many insurance plans, though prior authorization is usually required
What Is At-Home Ketamine Therapy?
At-home ketamine therapy uses sublingual (under-the-tongue) ketamine tablets or troches prescribed by a licensed provider through telehealth. Companies like Kalm Health offer monthly subscription programs that ship medication directly to your door.
-
Administration: Sublingual tablets taken at home on your own schedule
-
Setting: Your home — no clinic visits required
-
Frequency: Typically microdosed several times per week, as directed by your provider
-
Monitoring: Regular telehealth check-ins with your prescribing provider
-
Insurance: Generally not covered by insurance, but significantly lower out-of-pocket cost
Cost Comparison: Spravato vs At-Home Ketamine
This is where the difference gets real.
Spravato Costs
-
Without insurance: $600–$900+ per session
-
With insurance: Copays typically range from $10–$150 per session, but many plans require step therapy (trying other medications first)
-
Hidden costs: Travel to/from clinic, time off work for 2-3 hour appointments, parking, childcare
-
Monthly estimate (with insurance): $200–$600+ depending on frequency and copay
-
Monthly estimate (without insurance): $2,400–$7,200+
At-Home Ketamine Costs
-
Kalm Health: $124/month — includes medication, consultation, shipping, and ongoing provider access
-
Other telehealth providers: $150–$350/month
-
Hidden costs: Essentially none — no travel, no time off work, no facility fees
Bottom line: Even with insurance coverage, Spravato often costs more per month than at-home ketamine therapy. Without insurance, the difference is staggering.
Convenience Comparison
Spravato
- Requires scheduling appointments at a certified clinic
- Each visit takes 2-3 hours minimum (administration + observation period)
- Not available in all areas — limited certified facilities
- Cannot drive yourself home after treatment
- Twice weekly visits in the first month = significant time commitment
At-Home Ketamine
- Consultation and prescribing done via telehealth — often same day
- Medication shipped to your door
- Take your dose on your own schedule in your own home
- Available in all 50 states through licensed providers
- Automatic refills — no pharmacy visits or appointment scheduling
For people with busy schedules, limited transportation, or who live far from a certified Spravato clinic, at-home ketamine therapy removes nearly every logistical barrier.
Effectiveness: What Does the Research Say?
Both forms of ketamine have shown significant promise for treatment-resistant conditions:
-
Spravato: FDA-approved based on clinical trials showing improvement in depression symptoms. Works through the NMDA receptor pathway. Effects can be felt within hours to days.
-
Sublingual ketamine: While not FDA-approved specifically for depression (used off-label), extensive clinical research and real-world evidence support its effectiveness. Many patients report improvements in mood, anxiety, and PTSD symptoms within the first few weeks of microdosing.
The key difference: Spravato uses esketamine (the S-enantiomer), while at-home therapy typically uses racemic ketamine (both S and R enantiomers). Some researchers believe racemic ketamine may actually offer broader therapeutic benefits due to the R-enantiomer's additional mechanisms of action.
Who Is Each Option Best For?
Spravato might be better if you:
- Have insurance that fully covers it with low copays
- Live near a certified REMS facility
- Prefer in-person clinical supervision during treatment
- Have tried at-home options without success
At-home ketamine might be better if you:
- Want the most affordable option
- Value convenience and flexibility
- Don't live near a Spravato clinic
- Prefer managing your treatment from home
- Have a busy schedule that can't accommodate twice-weekly clinic visits
- Want to start treatment quickly without insurance authorization delays
