Understanding Duration, Effects, and What to Expect
If you’re considering Spravato® (esketamine) for depression, one of the most common questions is: How long does it actually last? The answer depends on what you mean by “last”—because Spravato works on multiple timelines: immediate effects, short-term relief, and long-term symptom improvement.
What Is Spravato?
Spravato is an FDA-approved nasal spray form of esketamine used to treat:
Major depressive disorder with suicidal thoughts
Unlike traditional antidepressants, Spravato works on the glutamate system, allowing for rapid symptom relief—sometimes within hours to days.
How Long Do Spravato Effects Last After Each Session?
Immediate Effects (0–2 Hours)
Dissociation or “floaty” feeling
Mild sedation
Changes in perception
These effects typically peak within the first hour
Wear off within 1.5–2 hours
This is why patients are monitored in the clinic after each session.
Short-Term Relief (Days to Weeks)
Many patients notice mood improvement within 24–72 hours
Relief may last several days after a single treatment
Effects build with repeated sessions
Long-Term Benefits (Weeks to Months)
With consistent treatment, benefits can last weeks or longer
Maintenance dosing helps sustain improvement
Some patients transition to less frequent treatments over time
How Long Does Spravato Stay in Your System?
Half-life: ~7–12 hours
Detectable in body: up to 2–3 days
Functional (antidepressant) effects: much longer
👉 Important: The therapeutic effects outlast the drug itself due to neuroplastic changes in the brain.
Why Do Spravato Effects Last Longer Than the Drug?
Spravato doesn’t just temporarily alter mood—it helps reset brain pathways.
Key Mechanisms:
Increases glutamate signaling
Promotes new neural connections (neuroplasticity)
Strengthens mood-regulating circuits
This is why some patients say:
“It feels like my brain is finally able to respond again.”
How Often Do You Need Spravato Treatments?
Induction Phase (Weeks 1–4)
2 sessions per week
Stabilization Phase (Weeks 5–8)
1 session per week
Maintenance Phase
Every 1–2 weeks (or individualized)
👉 This schedule is designed to extend how long the benefits last over time.
Factors That Affect How Long Spravato Lasts
Not everyone experiences the same duration of benefit. It can vary based on:
Severity of depression
Presence of PTSD or anxiety
Brain chemistry and treatment history
Consistency of sessions
Integration with therapy
How to Make Spravato Last Longer
You can extend and strengthen results by:
Attending all scheduled sessions
Engaging in therapy alongside treatment
Journaling or reflecting after sessions
Prioritizing sleep and stress management
Avoiding alcohol or substances (ie benzodiazepines) that blunt effects
Does Spravato Wear Off?
Yes—but in a controlled and manageable way.
Effects gradually taper without abrupt crashes
Maintenance treatments prevent relapse
Many patients experience increasingly longer relief over time
When Should You Expect to Feel Better?
Some patients: within hours to days
Most patients: noticeable change within 2–4 weeks
Full benefit: often builds over 1–2 months
Is Spravato a Long-Term Solution?
For many patients, yes it is.
Spravato is often used as part of a long-term treatment strategy, especially for:
Treatment-resistant depression
Chronic depression
Depression with suicidal thoughts
It can be combined with:
Oral antidepressants
Therapy
Lifestyle interventions
