People often hear about ketamine and esketamine, but many are unsure how they differ. Both treatments can help people with hard-to-treat depression, but they work in different ways and are used in different settings. This guide breaks down ketamine vs esketamine in simple, clear language so you can understand which option may be right for you.
Dr. Clayton L. Allison, Medical Director at NorTex Psychiatry, explains: “Patients don’t need a medical background to understand their options. When we explain ketamine comparison details in simple terms, people feel more confident and hopeful.”
Below is an easy guide to help you see the key differences.
Ketamine vs Esketamine: What’s the Difference? | Complete Treatment Comparison
Ketamine is an anesthetic that has been safely used for decades. Mental-health providers later discovered it can rapidly improve mood.
Esketamine is a newer form of ketamine. It is FDA-approved for treatment-resistant depression.
Here’s what that means in simple terms:
• Ketamine is the “parent” medicine
• Esketamine is one part of ketamine made into a nasal spray
• Both can help depression, but they follow different rules and dosing systems
Esketamine vs Ketamine Explained | Key Differences in Safety, Use & Results
Esketamine is more regulated. It must be used in a medical office under supervision. Ketamine infusions are also supervised, but the rules are different because it is an off-label treatment.
Key differences:
• Safety rules: Esketamine has FDA-required monitoring
• Effectiveness: Both may help depression when other treatments fail
• Experience: Esketamine is a nasal spray; ketamine is usually IV or IM
Brittany Huckaby, PHNP, shares: “Some patients prefer the structure of esketamine visits, while others respond better to IV ketamine. It’s our job to help match the treatment to the patient.”
Spravato vs Ketamine: Which Treatment Works Better for Depression?
There is no single “best” option for every person. Many people respond well to IV ketamine. Others do better with esketamine nasal spray. Your history, symptoms, and medication response help guide the choice.
Helpful points to consider:
• Esketamine may be better if you prefer an FDA-approved treatment
• Ketamine may help people who need a more flexible treatment plan
• Both work quickly compared to many antidepressants

Understanding Spravato Differences | FDA-Approved Esketamine vs Ketamine Infusions
Esketamine is only approved for treatment-resistant depression and must be paired with an oral antidepressant. Ketamine infusions can be used for several mood conditions and are not tied to one medication plan.
Ketamine vs Esketamine Treatments | Which Option Is Right for You?
Choosing between ketamine and esketamine depends on:
• Your health history
• Your past responses to medicine
• Your comfort level with IV vs nasal spray
• Whether you want an FDA-approved treatment
• Insurance and cost
Dr. Allison notes: “The right treatment is the one that fits the patient’s goals, symptoms, and safety needs. There is no one-size-fits-all answer.”
Esketamine (Spravato) vs Ketamine Infusions | A Side-by-Side Breakdown
Esketamine:
