If you have been researching treatment options for depression, especially treatment resistant depression, you may have come across two terms that sound almost identical: ketamine and Spravato.

Many people ask me the same question in my office: Is Spravato the same as ketamine?

The short answer is no. They are closely related, but they are not exactly the same. The differences matter, especially when it comes to safety, insurance coverage, effectiveness, and long term planning.

In this article, I will break-down the science in simple language so you can understand clearly and confidently.

What Is Ketamine?
Ketamine has been used in medicine since the 1970s. It was originally developed as an anesthetic, meaning it was used for surgery and emergency procedures. It is still used today in operating rooms and emergency departments.

Over the last twenty years, researchers discovered something surprising. At much lower doses than those used for anesthesia, ketamine can rapidly improve symptoms of severe depression.

Unlike traditional antidepressants that may take four to six weeks to work, ketamine can sometimes reduce depressive symptoms within hours to days. That discovery changed psychiatry!

What Is Spravato?
Spravato is a prescription nasal spray that contains a specific part of the ketamine molecule called esketamine.

Spravato was approved by the FDA in 2019 for adults with treatment resistant depression and later for major depressive disorder with suicidal thoughts.

It is given in a certified medical office under supervision. Patients self administer the nasal spray while medical staff monitor blood pressure and overall response for about two hours.

Spravato is not taken at home. It is part of a structured treatment program.

Racemic Mixture Versus Single Enantiomer
This is where things get scientific, but I will explain it in everyday terms.

Ketamine as it was originally developed is a racemic mixture. That means it contains two mirror image forms of the same molecule. These are called enantiomers.

Think of your hands. Your left and right hands are mirror images of each other. They look similar but are not identical.

Traditional ketamine contains both the left handed and right handed versions of the molecule mixed together.

Spravato contains only one of those mirror image forms. Specifically, it contains the S enantiomer called esketamine.

Why does this matter?
Research suggests that the S enantiomer may bind more strongly to certain brain receptors involved in mood regulation. By isolating this specific form, scientists created a more targeted medication.

So ketamine is both mirror images together. Spravato is just one mirror image purified and studied independently. This difference allowed Spravato to go through the full FDA approval process for depression.

How Do They Work in the Brain?
Both ketamine and Spravato affect a brain receptor called the NMDA receptor. This is part of the glutamate system, which plays a major role in mood, learning, and memory.

Most traditional antidepressants work on serotonin or norepinephrine. Ketamine and Spravato work differently.

They help stimulate new neural connections in areas of the brain involved in mood. Some researchers describe this as helping the brain form new pathways after being stuck in depressive patterns. This may explain why they can work more quickly than standard antidepressants.

Effectiveness
Both intravenous ketamine and Spravato have been shown to significantly reduce symptoms of depression, especially in people who have not responded to multiple antidepressants. Spravato went through large clinical trials before FDA approval. These trials showed that when combined with an oral antidepressant, Spravato improved depressive symptoms more than placebo.

Many patients report:
• Improved mood
• Reduced suicidal thoughts
• Increased motivation
• Greater emotional flexibility

No treatment works for everyone, but for individuals with treatment resistant depression, Spravato has become one of the most promising options available today.

Routes of Administration
​This is another major difference.
Ketamine for depression is most commonly given as:
• Intravenous infusion
• Intramuscular injection
• Sometimes oral or lozenge form

Spravato is given as:
• Nasal spray administered in a medical office

Each route has pros and cons.
Intravenous Ketamine Pros:
Precise dosing
Rapid onset
Strong research support

Cons
Not covered by insurance for depression
Higher out of pocket cost
Requires IV access

Oral or Lozenge Ketamine Pros
Convenience
Lower cost in some settings

Cons
Less predictable absorption
Not FDA approved for depression
Usually not covered by insurance

Spravato Nasal Spray Pros
FDA approved specifically for depression
Insurance coverage is common
Structured safety monitoring
Standardized dosing
Extensive research data

Cons
Must remain in clinic for observation
Requires transportation home after treatment

Insurance Coverage
This is a critical issue.

Spravato is FDA approved for treatment resistant depression. Due to this, most commercial insurance plans and many Medicare plans provide coverage for Spravato  when criteria are met.

Patients typically must:
• Have a diagnosis of major depressive disorder
• Have failed at least two antidepressants

Traditional ketamine infusions for depression are often considered off label. The vast majority of insurance companies do not cover them, which can lead to significant out of pocket expenses.

From a practical standpoint, Spravato is often more financially accessible.

Safety and Monitoring
Spravato is administered in a certified treatment center under a Risk Evaluation and Mitigation Strategy program required by the FDA.

Patients are monitored for:
• Blood pressure changes
• Sedation
• Dissociation
• Nausea

Most side effects occur during the observation period and resolve within a few hours.

Common side effects include:
• Dizziness
• Feeling disconnected
• Nausea
• Temporary increase in blood pressure

These effects are expected and usually manageable.

Common Contraindications
Spravato and ketamine are not appropriate for everyone.

They are typically avoided or used with caution in people with:
• Uncontrolled high blood pressure
• Aneurysms
• Certain vascular diseases
• History of psychosis
• Active substance misuse
• Pregnancy

A thorough psychiatric and medical evaluation is essential before starting treatment.

Is One Better Than the Other?
It depends on the situation.

Ketamine infusions may offer flexibility and individualized dosing. Cost and insurance barriers can limit access.

Spravato offers:
• FDA approval
• Standardized protocols
• Insurance coverage
• Structured safety oversight
• Extensive clinical trial data

For many patients, those factors provide reassurance and accessibility.

What Is the Treatment Experience Like?
Spravato treatment usually begins with twice weekly sessions for the first four weeks. After that, treatments gradually space out based on response.

Patients remain in a comfortable treatment room. Many listen to calming music or rest quietly during the observation period. You cannot drive the day of treatment. Most people feel back to baseline by the evening. Over a short time, many patients report that the “weight” of depression begins to lift.

A Positive Perspective
Depression can feel hopeless, especially when multiple medications have failed.
Spravato represents something different. It is based on a new understanding of how the brain regulates mood. It works faster than traditional antidepressants in many cases. It is supported by rigorous clinical research. It is covered by insurance for many patients.

It is not a miracle cure. It does not replace therapy or healthy lifestyle changes, but for individuals with treatment resistant depression, it can open a door that previously felt closed.

If you have struggled for years without meaningful relief, discussing Spravato with a qualified psychiatrist may be a worthwhile step.
​
You deserve options. You deserve hope. And modern psychiatry now offers more than ever before.

If you have lived with depression for a long time, you may know the feeling of doing everything “right” and still feeling stuck. You try therapy. You try medication. You adjust your sleep. You push yourself to function. The heaviness keeps returning like a fog that will not lift.

Many people I meet are not looking for hype. They are looking for something simple and honest with a real chance of relief.

Spravato is one of the most important advances in depression treatment in decades. It is not for every person with depression, and it is not a magic cure. For some adults with treatment resistant depression, Spravato can be a fantastic option that is worth a thoughtful, medically supervised trial.

What is Spravato?
Spravato is the brand name for esketamine, a nasal spray used for certain severe forms of depression. It is related to ketamine, an anesthetic that has been used in medicine for decades. Esketamine is one specific form of the ketamine molecule that was developed and studied for depression.

Spravato is a controlled medication and is only given in certified clinics under a safety program called REMS. You take it in the clinic, you are monitored, and you go home the same day with a responsible ride. It is not dispensed for home use.

What conditions is Spravato approved to treat?
Spravato has several FDA approvals that matter to patients:
Spravato was first approved in 2019 for adults with treatment resistant depression. 

In 2020, an additional approval covered depressive symptoms in adults with major depressive disorder who have acute suicidal thoughts or behaviors, in combination with an oral antidepressant. 

In January 2025, the FDA approved Spravato as monotherapy for treatment resistant depression. This means it can be used as a standalone treatment rather than only alongside a daily oral antidepressant.

That 2025 change matters for some patients who cannot tolerate standard antidepressants, or who have tried many traditional options.

What does “treatment resistant depression” really mean?
Treatment resistant depression usually means you have tried at least two different antidepressants at adequate doses and duration, and you still have significant symptoms.

This is not a personal failure. It does not mean you are “not trying hard enough.” Depression is a medical condition, and some forms are simply harder to treat.
One reason psychiatrists take treatment resistant depression seriously is that it tends to come with higher risks over time.

Why Spravato feels like a breakthrough for some people
Most traditional antidepressants work mainly through serotonin and norepinephrine systems. They can be helpful, but they often take weeks to work. Some people do not respond at all.

Spravato is different because it affects glutamate signaling, which is deeply involved in how brain circuits adapt, recover, and build healthier connections. That difference is one reason some patients notice improvement faster than they ever did with standard antidepressants.

Some patients describe Spravato as the first time in years they felt the depression “loosen its grip,” even if life is still complicated.  Some studies say Spravato is the most effective anti-depressant option in existence. 

A realistic story of how Spravato often enters someone’s life
Consider a patient I will call David.

David is 44. He runs a business, keeps showing up for his family, and looks “fine” on the outside. On the inside, he has been dragging himself through each day for years. He tried multiple medications. Some blunted the edge, but none brought him back to himself. He did therapy and learned skills, but his mood still felt stuck in a low gear.

Eventually he said, “I can function, but I’m not living.”

When David heard about Spravato, he was hopeful. He read reviews. He worried it would be intense. He also worried that hoping again would set him up for disappointment.

This is where I usually guide patients toward a balanced mindset:
You do not have to believe Spravato will fix everything.
You only need to be open to a well supervised trial to see whether your brain is one of the brains that responds.
For many people with treatment resistant depression, that openness is the beginning of a new chapter.

What do Spravato reviews most commonly say?
When you read Spravato reviews online, you will see patterns. Here are the most common themes, translated into plain language.
1) “It worked faster than anything else.” Many patients say they noticed something shift earlier than expected. Not always happiness, but often relief: less darkness, less hopelessness, more mental space.

This aligns with clinical studies showing meaningful symptom improvement in some patients, including early improvements in certain trials.

2) “It is strange, but manageable.” A lot of people describe the treatment session as unusual, dreamy, or disorienting, but not scary once they understood what to expect.

3) “The clinic experience matters.” People who report the best experiences often describe a calm setting, staff who communicate well, and a plan that includes therapy or coaching, not just the medication.

4) “It helped, but I needed ongoing structure.” Some patients feel better during the treatment course, but then notice symptoms return if treatment stops too suddenly. That is why maintenance planning is a big part of quality care.

Long term follow up research has focused on how to maintain response and reduce relapse risk over time.

5) “Side effects were real, but temporary.” Many reviews mention dizziness, nausea, sleepiness, and dissociation, mostly during the observation period.

Those match the adverse reactions listed in prescribing information.

How Spravato is given and why it requires supervision
Spravato is taken in the clinic because it can cause sedation, dissociation, and temporary changes in blood pressure. For safety, patients must be monitored for at least two hours after each dose.

You cannot drive yourself home after a session.

This supervision is not meant to make life difficult. It is meant to make treatment safe and predictable.

What happens at a typical Spravato visit?
While clinics vary, most follow a similar structure:
You arrive and check in
Your blood pressure is checked
You use the nasal spray under staff guidance
You sit in a comfortable monitored space for at least two hours
Your blood pressure, oxygen, and symptoms are rechecked
You are discharged when clinically stable
You go home with a ride and take it easy the rest of the day

The “two hour chair time” is one of the biggest barriers for busy people. For many treatment resistant patients, that time is an investment that can be well worth it, especially if symptoms have been dominating life for years.

Dosing schedule: what the treatment course usually looks like
Spravato treatment is commonly described in phases:
An induction phase with more frequent visits
A continuation phase with gradually reduced frequency
A maintenance phase tailored to your response

The induction typically involves doses 2x/week for 4 weeks.  The continuation phase is typically 1x/week for 4 weeks.  The maintenance phase is often one treatment every two weeks.

The FDA label describes dosing schedules for treatment resistant depression, and the key idea is that the plan is adjusted based on benefit and tolerability. A good clinic will not only follow the label, but also talk with you about goals, progress, and what “success” looks like for you.

What does Spravato feel like?
Most patients do not feel “knocked out.” Instead, they may feel a temporary shift in perception.

Common descriptions include:
Feeling detached from the body
Feeling like time is different
Feeling floaty or heavy
Feeling emotionally distant from distress
Feeling sleepy
Feeling mildly nauseated
This is usually time limited and improves during the observation period.

Spravato can also raise blood pressure temporarily, peaking around 40 minutes after dosing and usually resolving over a few hours. 

Side effects and safety concerns you should know
Spravato has important safety warnings, and being honest about them is part of good psychiatric care. Common side effects include dissociation, nausea, dizziness, headache, feeling drunk, increased blood pressure, and sedation. 

Due to risks like sedation, dissociation, and respiratory depression, Spravato is restricted to certified settings with monitoring. Do not judge Spravato by a scary headline. Judge it by how responsibly it is delivered in a medical setting.

Is Spravato addictive?
Spravato is a Schedule III controlled substance and carries warnings about misuse and abuse potential. The reassuring aspect is that the REMS system is designed specifically to reduce misuse risk by keeping dosing in the clinic and preventing take home dispensing. 

If you have a history of substance misuse, that does not automatically disqualify you, but it does mean your psychiatrist should evaluate carefully and discuss safeguards. Some more recent studies even suggest that Spravato reduces the risk of alcohol abuse.

Who is most likely to benefit from a Spravato trial?

Spravato is most often considered when:
You have treatment resistant depression and have tried multiple standard options.
Depression is causing real impairment in work, relationships, parenting, or basic functioning
You have persistent hopelessness or chronic suicidal thinking
You need a different mechanism of action than you have tried before

Spravato is not a typical first step. If you have been fighting depression for a long time, it can be a very reasonable next step. If your depression has not responded after solid trials of standard treatments, it is often worth exploring Spravato rather than resigning yourself to “this is just my life now.”

Not everyone responds, but many do, and you cannot know which group you are in without a thoughtful trial.

Who should be cautious or may not be a good candidate?

Spravato requires careful screening, especially for:
Uncontrolled high blood pressure or certain blood vessel problems, because of blood pressure increases
Certain psychiatric histories where dissociation may be destabilizing
Active uncontrolled substance use
Pregnancy

A good evaluation is not a gatekeeping exercise. It is how we make treatment safer and more successful.

Why the best Spravato reviews often mention therapy
Spravato can reduce symptoms, but recovery is usually more than symptom reduction. When depression improves, patients often need to rebuild routines, relationships, and confidence. Therapy can help you use the window of improvement to make durable changes.

How to judge a Spravato clinic before you start?
If you are considering a trial, here are signs of high quality care:
They do a real psychiatric evaluation, not a quick checklist
They review your medication history carefully
They monitor blood pressure and safety properly and follow the REMS rules
They explain what dissociation is and how they support you through it
They talk about a plan for induction, continuation, and maintenance
They coordinate with therapy or encourage psychotherapy support
They set expectations clearly, including what happens if you do not respond

Frequently asked questions that come up in Spravato reviews
How soon will I know if it is working?
Some people notice improvement early, within hours. Others need several sessions to see a clear trend.

Will I feel high?
Some people feel altered or detached temporarily. Many do not describe it as a euphoric “high” as it is more like a brief shift in perception that fades.

Do I have to take an oral antidepressant with it?
As of the January 2025 approval, Spravato can be used as monotherapy for treatment resistant depression in appropriate patients.

What if it works and then fades?
That is common enough that maintenance planning matters. Clinicians use structured tapering and symptom guided frequency to sustain benefit when possible.
