Ketamine therapy, emerging from its initial use in the 1960s as an anesthetic, has captivated professionals like Dr. Ken Stewart with its profound potential in mental health treatment. This dissociative anesthetic, known for alleviating pain and inducing sedation, unexpectedly revealed its prowess against depression and suicidal thoughts, particularly in emergency situations. Insightful cases, such as long-term relief following a crisis intervention, have propelled experts to consider ketamine’s promising role in combatting severe mental health conditions.


Potential Side Effects:


While ketamine offers new horizons in depression treatment, it’s important to acknowledge it isn’t officially licensed for this purpose, and its long-term impacts remain unclear. Additionally, rare acute side effects may surface, adding to the unpredictability of its application.


Approximately 10% of individuals undergoing ketamine infusion face significantly challenging experiences. Should side effects become intolerable, they typically subside within 15 minutes of halting the infusion. However, a notable concern is the potential intensification of depressive symptoms and suicidal thoughts, persisting for up to two weeks post-administration. This aftermath is occasionally so distressing that some individuals discontinue treatment. Conversely, continued therapy often turns a corner after an additional one or two sessions, marking the commencement of relief.


In the broader experience spectrum, while 10% undergo discomfort, about half of the remaining recipients report a particularly positive response, with the rest finding the experience neutral—neither harmful nor particularly enjoyable. This underscores the diverse responses to ketamine treatment, necessitating a personalized approach to care.


Ketamine’s Interaction with the Brain: A Gateway to Healing


Diving into the mechanics of ketamine reveals its extensive impact beyond anesthesia. Its magic lies in the ability to target NMDA receptors in the brain, crucial nodes that regulate neural stimulation through neurotransmitters like glutamate.


Under normal circumstances, these receptors are beneficial, maintaining the brain’s electrical rhythm. However, prolonged neural excitement can be detrimental, causing neurons to deteriorate and potentially triggering psychological conditions such as depression or anxiety, often rooted in NMDA receptor dysfunctions.


Ketamine intervenes by blocking these receptors, fostering the creation of new neural pathways and synapses that facilitate the brain’s healing from past traumas or dysfunctions. By also inhibiting glutamate, a key player in memory and emotional regulation, ketamine induces calm and temporary amnesia, beneficial during post-surgical recovery.


Beyond Anesthesia: The Versatility of Ketamine Treatment


W recognize ketamine’s transformative role outside surgical settings. Its calming and pain-relieving attributes have surpassed medical expectations, providing relief in diverse conditions including, but not limited to:



One notable benefit is ketamine’s ability to reduce reliance on narcotic pain relievers, minimizing the risks associated with their prolonged use, such as tolerance and potential complications. For those battling chronic pain, ketamine emerges as a compelling alternative.


What sets ketamine apart is its rapid action — a stark contrast to conventional antidepressants that require an extended period to take effect. Patients can feel changes within hours of ketamine therapy, a critical attribute, especially in treating acute depressive episodes.


Furthermore, ketamine assures safety in its application, particularly during surgeries, given its minimal impact on breathing and blood pressure. This aspect renders it favorable compared to other sedatives known to compromise physiological functions.


Despite its promising outcomes, ketamine therapy necessitates a thorough evaluation. It isn’t a universal remedy and may not suit everyone. We are committed to guiding you through the nuances of this treatment, ensuring an understanding of its potential side effects and assessing its appropriateness for your unique health context.


Understanding Ketamine’s Side Effects: A Comprehensive Overview


Ketamine, while renowned for its therapeutic effects, can also induce a spectrum of transient side effects. These reactions tend to escalate with higher doses, though the correlation between dosage and side effects varies, often unpredictably, even within the same individual.


Immediate Reactions During or Post-Treatment:


  1. Dissociation: Patients often report a detachment where the mind and body seem disconnected. This can escalate to an ‘out-of-body’ experience or a sensation of disowning parts of the body, such as feeling that one’s feet are not one’s own.
  2. Ego Dissolution: Some individuals describe a profound sense of unity with the surroundings or a minimization of the self, akin to being a minuscule entity within a vast space. While often accompanied by a sense of wonder, this can be intimidating or unsettling.
  3. Physical Discomforts: These encompass dizziness, light-headedness akin to intoxication, and post-treatment fatigue.
  4. Perceptual Changes: Altered visual or auditory perceptions, making the environment appear strange or unfamiliar.
  5. Nausea or Vomiting: Preventable or manageable with anti-nausea medications. Patients are advised to avoid heavy meals pre-treatment to mitigate this.
  6. Anxiety or Panic: Unexpected surges of anxiety, occasionally reaching panic levels or manifesting as a ‘near-death’ experience, can occur. These episodes, however abrupt, typically wane quickly once the ketamine infusion ceases, resolving within minutes.
  7. Headache: Generally responsive to common pain relief medications like paracetamol.
  8. Tinnitus: An emergence or amplification of a ringing noise in the ears, potentially intensified by certain concurrent medications. If persistent, it’s crucial to report this as continued ketamine treatment may impact hearing.

Physical Implications of the Infusion Process:


It’s paramount for patients to communicate any distressing or persistent side effects to our team, ensuring a safe and more comfortable treatment experience. Individual responses may vary, emphasizing the importance of personalized care and attention.


Eligibility Criteria for Ketamine Therapy: Understanding the Scope and Limitations


Ketamine therapy represents a beacon of hope for those grappling with treatment-resistant depression, unresponsive to conventional interventions such as medications or psychotherapy. However, while its potential is undeniable, it’s crucial to delineate who might not be suitable for this treatment due to the overriding risks associated with certain health profiles.


Potential Contraindications: Assessing the Risks


The therapeutic promise of ketamine could be counterbalanced by substantial risks in patients with specific health conditions, including:


  1. Cardiovascular Complications: Individuals with a history of hypertension, angina, arrhythmias, or previous instances of heart attacks or strokes may face elevated risks.
  2. Hyperthyroidism: Patients with overactive thyroid glands could encounter adverse effects.
  3. Advanced Liver Disease: The presence of significant liver dysfunction can hinder the safe administration of ketamine.
  4. Certain Psychiatric Conditions: Those experiencing acute phases of delirium, psychosis, or schizophrenia may find the therapy exacerbating their symptoms.
  5. Substance Use Disorders: A history of alcohol or drug abuse might complicate the treatment’s outcomes.
  6. Pregnancy: Due to potential risks to the unborn child, pregnant individuals are advised against undergoing ketamine therapy.
  7. Mobility Restrictions: Certain limitations in movement may impact the feasibility of regular treatment sessions.

Navigating the Decision-Making Process


Given these considerations, the journey towards deciding on ketamine therapy should be navigated hand-in-hand with a trusted healthcare provider. A thorough discussion regarding one’s specific risk factors, medical history, and the balancing of potential benefits against possible risks is imperative.


This dialogue ensures an informed and safety-centric approach, allowing patients and doctors to consider ketamine therapy not as a universal solution but as a tailored intervention aligned with the individual’s overall health context
