Frequently Asked Questions (FAQ) About Ketamine Therapy

---

Ketamine therapy refers to the medical use of ketamine to treat conditions such as depression, anxiety, post-traumatic stress disorder (PTSD), and chronic pain. Originally developed as an anesthetic, ketamine has been found to have fast-acting antidepressant properties when administered in sub-anesthetic doses.​

Ketamine primarily interacts with the brain's glutamate system, a crucial neurotransmitter involved in neural communication and plasticity. By modulating glutamate receptors, ketamine promotes neural growth and enhances connectivity in brain circuits associated with mood and emotions, leading to rapid improvement in depressive symptoms. ​

Ketamine can be administered through various routes, each with unique characteristics:​

• Intravenous (IV) Infusion: Delivers ketamine directly into the bloodstream, allowing for precise control over dosage and rapid onset of effects.​
   
• Intramuscular (IM) Injection: Involves injecting ketamine into a muscle, offering a high bioavailability with effects typically manifesting within minutes.​
   
• Intranasal (IN) Administration: Utilizes a nasal spray to deliver ketamine through the nasal mucosa, providing a less invasive option with moderate bioavailability.​
   
• Sublingual Administration: Entails placing ketamine under the tongue for absorption through the mucous membranes, offering moderate bioavailability.​National Pain Centers®+1NCBI+1
   
• Nebulized (Inhaled) Ketamine: Involves inhaling ketamine vapor through a nebulizer, providing an innovative and non-invasive route of administration.​
   

Each route has its advantages and considerations, and the choice depends on individual patient needs, clinical settings, and treatment goals. ​

Ketamine therapy is often considered for individuals who have not responded adequately to traditional treatments, such as standard antidepressants or psychotherapy. It may be suitable for patients with treatment-resistant depression, severe anxiety disorders, PTSD, and certain chronic pain conditions. A comprehensive evaluation by a qualified healthcare professional is essential to determine eligibility for ketamine therapy.​

During a ketamine treatment session, the following can be expected:​

• Preparation: A healthcare provider will review your medical history and discuss the treatment process.​ 
• Administration: Ketamine is administered via the chosen route (e.g., IV, IM, IN) in a controlled clinical setting. 
• Monitoring: Patients are closely monitored throughout the session for vital signs and any potential side effects.​
• Duration: The effects of ketamine typically begin within minutes, with the acute experience lasting approximately 40 minutes to an hour.​
• Post-Treatment: Patients may need to rest briefly after the session before being discharged. ​

Common side effects of ketamine therapy may include:​

• Dissociation: A temporary feeling of detachment from reality or one's body.​
   
• Dizziness: Lightheadedness or a sensation of spinning.​
   
• Nausea: A feeling of queasiness or upset stomach.​
   
• Increased Blood Pressure: A temporary rise in blood pressure levels.​
   

These side effects are typically short-lived and subside shortly after the session. Ketamine therapy is generally considered safe when administered by trained professionals in a controlled setting. ​

One of the notable benefits of ketamine therapy is its rapid onset of action. Many patients report significant improvements in mood and reduction in depressive symptoms within hours to days after treatment, compared to traditional antidepressants that may take weeks to show effects. ​

The number of ketamine treatments varies based on individual response and the condition being treated. A common protocol involves an initial series of six infusions over two to three weeks, followed by maintenance sessions as needed. 

Coverage for ketamine therapy varies by insurance provider and the specific treatment administered. While some insurance plans may cover FDA-approved treatments like esketamine (Spravato), coverage for other forms of ketamine therapy may be limited. It's essential to consult with your insurance provider and treatment center to understand your options and coverage.
