However, alongside this rising curiosity often comes a degree of confusion, stigma, and hesitation. Many people considering these options wonder: Is ketamine an opioid? Is it safe? How does it actually work?
This comprehensive guide aims to demystify ketamine and esketamine therapy. We’ll explain what these treatments are, how they work, who they can help, and what prospective patients can truly expect throughout their journey.
If you or a loved one are considering exploring new avenues for mental health treatment, read on to gain clarity and confidence.
II. Understanding Ketamine and Esketamine
Ketamine’s journey in medicine began in the 1960s as an anesthetic, proving to be a highly effective and safe option for various medical procedures. Its versatility and unique pharmacological profile quickly made it a staple in operating rooms worldwide. Over time, researchers began to uncover its surprising potential beyond anesthesia, particularly in the realm of mental health.
It’s crucial to differentiate between ketamine and esketamine. While both are derived from the same compound, esketamine is a specific formulation — often recognized by its brand name, Spravato®. Spravato® holds the distinction of being an FDA-approved version of ketamine, specifically sanctioned for treatment-resistant depression and major depressive disorder with acute suicidal ideation or behavior. This FDA approval underscores its established safety and efficacy within a regulated medical framework. The esketamine drug class is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist.
These treatments are administered through different routes. Ketamine is typically delivered via ketamine infusion therapy, where it’s given intravenously in a controlled medical setting. Esketamine, on the other hand, is administered as a nasal spray, offering a less invasive option for patients.

III. Addressing Safety and Misconceptions
The relatively novel application of ketamine in mental health often leads to understandable questions and common misconceptions. Let’s address some of the most prominent ones head-on.
A. Myth 1: ‘Is Ketamine an Opioid?’
One of the most frequent questions we encounter is, “Is ketamine an opioid?” The answer is a definitive no.
Scientifically, ketamine belongs to a class of drugs known as dissociative anesthetics. Its primary mechanism of action involves targeting the NMDA receptor in the brain, which is distinctly different from how opioids work. Opioids primarily interact with opioid receptors, leading to pain relief and, in some cases, a high potential for physical dependence and addiction due to their impact on the brain’s reward system.
Ketamine, while capable of producing a “dissociative” state at higher doses, does not bind to opioid receptors. This fundamental difference in pharmacology means that ketamine does not carry the same risks associated with opioid use, such as respiratory depression or the specific withdrawal syndromes seen with narcotics.

B. Myth 2: ‘Is Ketamine Addictive?’
Another common question that arises is, “Is ketamine addictive?” While recreational misuse of any substance carries risks, clinical evidence and safety protocols surrounding medically supervised ketamine and esketamine treatments demonstrate a low potential for addiction when administered in a controlled healthcare setting.
Unlike substances with a high potential for abuse that rapidly stimulate dopamine release in the brain’s reward pathways, therapeutic ketamine use under medical supervision is structured to minimize such risks. Treatment plans typically involve carefully measured doses, infrequent administration, and close monitoring by trained medical professionals. This supervised approach, combined with the non-addictive nature of its pharmacological profile when used therapeutically, helps ensure patient safety and mitigate concerns about dependency. Medical literature consistently supports the safety of controlled use.

IV. How the Treatment Works
Understanding the “how” behind ketamine and esketamine therapy is key to appreciating their unique effectiveness. Unlike traditional antidepressants that often take weeks to show results by gradually adjusting neurotransmitter levels, ketamine and esketamine work through a different and more rapid neurobiological pathway.
These treatments primarily target the NMDA receptor, a crucial player in brain function. By modulating activity at this receptor, ketamine initiates a cascade of events that promotes synaptic plasticity — essentially, the brain’s ability to form new connections and pathways.
This process, often referred to as synaptogenesis, is believed to rapidly restore damaged neural circuits in areas of the brain responsible for cognition, mood, and emotional regulation. This is a significant departure from selective serotonin reuptake inhibitors (SSRIs), which primarily focus on increasing the availability of neurotransmitters like serotonin in the synaptic cleft.
Think of it like this: If traditional antidepressants are like adding more bricks to a wall, ketamine therapy is like rebuilding the foundation and repairing the framework, allowing new, stronger structures to form quickly. This rapid synaptic growth can lead to a quicker alleviation of severe depressive symptoms and improved mood regulation. Both ketamine infusion therapy and therapies using the esketamine drug class leverage this fascinating mechanism to provide relief.

V. What to Expect From the Patient Experience
Embarking on a new treatment journey can be daunting, but knowing what to expect can significantly ease anxieties. A typical ketamine or esketamine treatment session is a carefully monitored and structured process designed for patient safety and comfort.
Your experience will usually begin with an intake process, where medical staff will review your vital signs and overall well-being. During the treatment itself, whether it’s a ketamine infusion therapy or esketamine nasal spray, you’ll be in a comfortable, quiet environment. You may experience what is known as dissociation — a temporary feeling of detachment from your body or surroundings. This is a common and expected part of the experience, often described as feeling “light” or “dream-like.” It’s important to normalize these emotional and physical experiences; they are a sign that the medication is working on a neurological level. Some patients may also feel a sense of fatigue after the session.
Safety measures are essential. Before treatment begins, your medical history will be thoroughly reviewed to identify any esketamine contraindications, such as uncontrolled high blood pressure, aneurysmal vascular disease, or a history of psychosis. Throughout the session, your vital signs will be continuously monitored by trained healthcare professionals. After the treatment, there will be a recovery period, where you’ll be observed until the acute effects have subsided, ensuring you are stable before leaving the clinic. It’s often recommended to have someone drive you home after a session.

VI. How Long Do the Effects Last?
One of the most common questions patients have is, “How long does ketamine pain relief last?” Or, more broadly, “How long do the mood-elevating effects endure?” The timeline for symptom relief and the duration of benefits can vary significantly among individuals. Many patients report an improvement in their symptoms within hours or days of their initial treatment, a stark contrast to the weeks or months often required for traditional antidepressants.
The number of sessions needed also varies. Initially, a series of treatments is often recommended over a few weeks to achieve optimal results. Following this initial phase, many patients transition to a maintenance schedule, with booster sessions administered as needed to sustain the therapeutic effects. These maintenance sessions might be weekly, bi-weekly, or even monthly, depending on individual response and the severity of symptoms.
It’s crucial to understand that outcomes are highly individualized. Factors such as the nature and severity of the condition, individual metabolism, and adherence to the treatment plan can all influence the longevity of the effects. Our team works closely with each patient to develop a personalized treatment plan and ongoing support process to maximize and sustain the benefits.

VII. Who Might Be a Good Candidate?
Ketamine and esketamine therapy are not one-size-fits-all solutions, but they offer significant hope for specific patient profiles, particularly those who have struggled to find relief with conventional treatments. Ideal candidates often include individuals diagnosed with:
• Treatment-resistant depression (TRD): This is defined as major depressive disorder that has not responded to at least two different antidepressant treatments of adequate duration and dose.
• Severe anxiety disorders: For some forms of anxiety, especially when co-occurring with depression.
• Post-traumatic stress disorder (PTSD): Emerging research suggests benefits for certain PTSD symptoms.
Before any treatment begins, a thorough medical and psychiatric evaluation is mandatory. This process involves a comprehensive review of your health history, current medications, and a detailed assessment of your mental health status. This evaluation helps determine if ketamine or esketamine therapy is a safe and appropriate option for you.
During this assessment, potential ketamine or esketamine long-term side effects and any other risks will be thoroughly discussed. While generally well-tolerated, potential long-term considerations may include bladder issues with chronic, high-dose use (not typically seen with therapeutic doses) or mild cognitive effects that are usually transient. Comprehensive risk screening ensures that all potential factors are considered. It is vital to emphasize the importance of professional consultation rather than self-diagnosis. A qualified healthcare provider can accurately assess your condition and guide you toward the most suitable treatment path.
