About Ketamine
For what psychiatric disorders is ketamine best proven to be effective for?
At the CRTCE we treat Major Depressive Disorder, and Bipolar Depression. Individuals Post Traumatic Stress Disorder (PTSD) or Obsessive-Compulsive Disorder (OCD) will be considered on a case-by-case basis for potential investigational use of intravenous ketamine.
How long will the effects of ketamine last?
The long-term efficacies of ketamine in individuals who have responded to this treatment modality are not yet fully known. Emerging evidence indicates that some individuals remains well for several months. Undoubtedly, there will be some individuals who remain well for longer periods of time. It’s also known that other individuals will require booster sessions to maintain their feelings of wellness. The booster sessions are typically administered approximately once per month.

Treatments at CRTCE
What formulations of ketamine are available at CRTCE?
Ketamine is delivered through intravenous infusion, or a intranasal spray.
How long do ketamine treatments take and how long do I need to stay at the clinic?
IV Ketamine infusions are given over 40 minutes. Post infusion patients will be required to stay up to 30 minutes of recovery time. Patients who receive intranasal ketamine are required to stay 2 hours at the clinic.
How many treatments of ketamine will I require?
For IV Ketamine the acute treatment phase consists of 4 to 6 infusions over a course of 2 weeks. For esketamine the acute treatment phase consists of 2 intranasal administrations per week for 2 to 4 weeks.
How many infusions do I need?
Typically patients who will need to come back for maintenance therapy is every 2-6 weeks.
How long does it take before ketamine begins to work?
Based on the available evidence, individuals receiving ketamine begin to report relief of depression within one day of administration of the first infusion. Others may take longer but overall the majority of people who are going to benefit from ketamine benefit from 1-2 weeks.
What is the usual dose of ketamine administered for treatment resistant mood disorders?
Generally speaking, the dose of ketamine administered is 0.5mg/kg to 0.75mg/kg. This dose results in a blood concentration of ketamine of about 10%-20% of what is usually used in anesthesia. Intranasal ketamine doses vary from 28mg to 84mg.
Can I eat during an infusion?
You’ll be asked to not eat or drink during the infusion and approximately 6-8 hours before the treatment.
What are common side effects?
The most common side effects of ketamine are dissociation, which is when images appear somewhat distorted. Dissociation can affect up to a third of people during the first infusion. The overall number of people who experience dissociation decreases with each subsequent infusion. It is also noted that some people may have an increase in blood pressure or heart rate during infusion therapy. That will be monitored closely during by your health care team. Although it is rare, some people may experience changes in liver or kidney function, and/or notice blood in their urine. These are considered rare events and more typically associated with much higher doses of ketamine for longer periods of time and/or people who abuse ketamine.
Is it safe for me to drive home after ketamine treatments?
No. You’ll need to be accompanied on your way home following the infusion of ketamine treatment.
Are there any medications that interfere?
Drugs that may interfere with ketamine treatments may be determined by your health care team at the CRTCE during assessment.
Will there be research studies conducted at the Canadian Rapid Treatment Center of Excellence that I may be able to participate in?
Yes. The Canadian Rapid Treatment Center of Excellence is associated with the Mood Disorder Psychopharmacology Unit, one of the world’s leading centers for identifying causes and cures of mood disorders. There are many research protocols that will be conducted in addition to offering ketamine treatment for mood disorders.
How much do treatments cost at the CRTCE?
Depending on the ketamine formulation (eg, IV ketamine versus sublingual ketamine versus esketamine nasal spray) prices range from $200 to $1000 per dose. The number of doses for an acute course of treatment also varies from 4-8 treatments.
