Ketamine for Mental Health: Effectiveness and Options
December 7, 2025
For individuals with treatment-resistant depression, conventional antidepressants don’t always work, leaving a critical need for new options. Ketamine therapy offers a different kind of hope by working on a different brain pathway to provide rapid relief—often within hours or days instead of weeks.
The FDA-approved nasal ketamine infusion, Spravato (based on esketamine), has made this treatment more accessible, especially for those who haven’t found success with other therapies. This article explains how ketamine therapy works, who can benefit, what to expect during treatment, and how to navigate insurance coverage while choosing the right clinic for your care.
Key takeaways
- Ketamine therapy provides rapid relief for treatment-resistant depression—often within hours or days—by targeting glutamate receptors instead of serotonin.
- Spravato has been proven effective and safe by clinical trials, and it is covered by insurance most of the times, as it is approved by the Food and Drug Administration.
- FDA-approved Spravato is typically covered by insurance, while intravenous ketamine (IV ketamine) usually requires out-of-pocket payment.
- Spravato is only FDA-approved for treatment-resistant depression/ major depressive disorder. Systemic reviews are still needed on the treatment response for using Spravato for other mood disorders, mental health disorders, and psychiatric conditions (like post-traumatic stress disorder, bipolar disorder, refractory anxiety disorders, etc.)
- You may qualify if you’ve tried at least two antidepressants for 6-8 weeks each without adequate relief.
- Marpa Minds combines medical expertise with spa-like environments for safe, comfortable treatment.
- Getting started involves verifying insurance, consulting experienced providers, and planning ongoing support.
What is ketamine therapy for mental health
Ketamine therapy is a medical treatment that uses controlled doses of ketamine to help people with depression and other mental health conditions. This means you receive the medication in a clinical setting while healthcare professionals monitor your safety and comfort.
Originally developed as an anesthetic in the 1960s, ketamine now serves a new purpose in mental health care. The FDA approved a form of ketamine called esketamine (brand name Spravato) specifically for treatment-resistant depression in 2019.
Unlike traditional antidepressants that target serotonin, ketamine works on a different brain chemical called glutamate. This unique approach can provide relief within hours or days instead of the weeks required by conventional medications.
How does ketamine therapy work
Ketamine blocks specific receptors in your brain called NMDA receptors in the brain glutamate systems. When these receptors are blocked, your brain releases more glutamate, which triggers a cascade of changes that can rapidly improve mood.
This process also promotes neural plasticity — your brain’s ability to form new connections between nerve cells. These new connections help your brain develop healthier patterns of thinking and emotional processing.
The rapid action happens because ketamine bypasses the usual pathways that traditional antidepressants use. While SSRIs work by gradually increasing serotonin levels, ketamine creates immediate changes in brain chemistry that can lift severe depression symptoms quickly.
Who can benefit from ketamine treatment
You might be a candidate for ketamine therapy if you have treatment-resistant depression. This means you’ve tried at least two different antidepressants for 6-8 weeks each without finding adequate relief.
The FDA specifically approved Spravato for:
- Adults with treatment-resistant depression: Those who haven’t responded to multiple medication trials
- Adults with major depressive disorder and suicidal thoughts: For rapid symptom relief in crisis situations
Before starting treatment, you’ll need a comprehensive evaluation. Marpa Minds and similar clinics assess your medical history, current medications, and overall health to ensure ketamine is safe for you.
Some conditions may prevent you from receiving ketamine therapy, including uncontrolled high blood pressure, active psychosis, or current substance abuse issues.
7 ways to experience ketamine for depression, anxiety, and more
Ketamine therapy can be administered a number of ways, especially when it comes to treatment-refractory depression. Although its antidepressant effects are similar, the different ways of administration can make a very big difference in terms of behavioral effects and approachability.
Here’s what you need to know about this:
1. Infusion therapy (intravenous ketamine)
IV ketamine delivers the medication directly into your bloodstream through a small needle. The infusion typically takes about 40 minutes while you relax in a comfortable chair.
Intravenous ketamine allows precise dosing and immediate adjustments if needed. Though considered off-label for depression, IV ketamine has extensive research support.
2. Nasal spray (intranasal ketamine)
Spravato is the FDA-approved nasal spray form of ketamine (sometimes referred to as intranasal ketamine). You administer it yourself under medical supervision at certified treatment centers like Marpa Minds.
Insurance often covers intranasal esketamine for eligible patients, making it more accessible than other forms of ketamine therapy.
3. Oral or sublingual doses
Some clinics offer ketamine as a tablet you swallow or dissolve under your tongue. These methods work more slowly than IV or nasal spray options.
Absorption can vary between individuals, requiring careful dose adjustments.
4. IM (intramuscular) injections
Intramuscular injections deliver ketamine into muscle tissue, usually in your arm or thigh. This method works faster than oral doses but may be less predictable than IV administration.
5. Combining therapy sessions with ketamine
Ketamine-assisted psychotherapy pairs medication with talk therapy. The altered state ketamine creates can help you process emotions and gain new insights during therapy sessions.
6. Ongoing follow-up and monitoring
Regular check-ins with your provider ensure the treatment continues working effectively. Your team adjusts dosing and frequency based on your response and needs.
7. Leveraging a serene clinical environment
The setting matters for your comfort and outcomes. Spa-like environments with soft lighting and comfortable furnishings help you relax during treatment.
Are there side effects, or does ketamine therapy get you high?
Ketamine can cause temporary side effects during treatment, but these are carefully managed in clinical settings. You might experience mild dissociation — feeling detached from your surroundings or having dreamlike sensations.
In most cases, these psychoactive effects are actually what promote functional brain connectivity and create the new neural path your brain needs to overcome depressive symptoms.
Common side effects during treatment include:
- Floating sensations: Feeling disconnected from your body
- Mild nausea: Usually manageable with anti-nausea medication
- Blood pressure changes: Monitored throughout your session
- Drowsiness: Most people feel tired after treatment
These effects typically resolve within two hours after your session ends. The doses used for depression are much lower than those used for anesthesia, and you won’t experience the intense high associated with recreational use.
Marpa Minds staff monitor you throughout treatment to ensure your safety and comfort.
How to manage insurance and costs for ketamine psychiatry
Insurance coverage depends on which type of ketamine treatment you choose. Understanding your options helps you plan financially for your care.
Spravato typically receives insurance coverage because of its FDA approval. Most major insurance plans, including Blue Cross Blue Shield, Aetna, and United Healthcare, cover it for eligible patients.
For Spravato coverage, you’ll need:
- Prior authorization: Your doctor submits documentation showing you meet criteria
- Treatment history: Proof you’ve tried other antidepressants without success
- Ongoing documentation: Regular updates on your progress
IV ketamine usually requires out-of-pocket payment since it’s considered off-label use. However, you can often use HSA or FSA funds for these treatments.
At Marpa Minds, we believe your well-being should not lie in the hands of fate. So our ketamine clinic will help you get help for your mental health disorder, from the beginning to the end (including dealing with insurance companies and even psychological therapy to help you make the most out of your treatment).
Choosing a calming, professional setting for ketamine mental health treatment
The right treatment environment significantly impacts your experience and outcomes. Look for clinics that prioritize both medical excellence and patient comfort.
Essential features of a quality ketamine clinic include:
- Licensed medical professionals: Psychiatrists or anesthesiologists should oversee treatment
- Emergency preparedness: Proper equipment and protocols for any complications
- Comfortable spaces: Relaxing environments that reduce anxiety
- Privacy protection: Discrete locations and confidential care
Marpa Minds exemplifies this approach with spa-like treatment rooms, experienced medical staff, and comprehensive support throughout your journey.
What to expect during ketamine infusion therapy and other formats
1. Preparation and assessment
Your first appointment includes a detailed medical evaluation. The team reviews your health history, current medications, and treatment goals.
You’ll receive specific instructions about eating and drinking before treatment. Some medications may need temporary adjustment.
2. During the session (monitoring and support)
Once settled in a comfortable treatment room, the medication administration begins. Staff monitor your vital signs continuously throughout the session.
You might listen to calming music or simply rest during the 40-minute to 2-hour treatment period. Many people describe the experience as peaceful and relaxing.
3. Post-treatment integration
After the medication effects wear off, you’ll rest until you feel ready to leave. This usually takes about two hours total.
You cannot drive for 24 hours after treatment, so arrange transportation in advance. Follow-up appointments help track your progress and plan future sessions.
5 steps to begin your ketamine therapy journey
Step 1: Verify insurance coverage
Call your insurance company to ask about ketamine therapy benefits. Request specific information about Spravato coverage and any requirements for approval.
