The full spectrum of ketamine’s antidepressant and antisuicidal effects have not been fully explained. However, we do know that this novel approach to therapy works with the brain’s NMDA receptors, which play a role in several neurological functions like memory, learning, movement and more. This is an alternative to SSRIs (Prozac, Paxil, Zoloft), which work with serotonin receptors.

We also know that ketamine affects other receptors and pathways in the brain, which creates a combination of positive effects that help combat depression.

Doctors will begin by assessing the patient, including vital signs, mood and response to previous treatment (if any). Patients will have their blood pressure checked to ensure a proper level since patients with high blood pressure are not eligible for ketamine therapy.

Patients will likely be asked to blow their nose and will then be reclined at a 45-degree angle. The patient is given the nasal spray and self-administers the drug by inhaling the spray in each nostril. After 5 minutes, a second dose will be administered, and then after another 5 minutes an optional third dose will be administered.

After the last dose is inhaled, the patient will be monitored and then periodically assessed for depression, suicidality, hallucinations, dissociation and physical symptoms. The doctor will also keep tabs on the patient’s blood pressure. After the 2-hour mark, the patient will be able to go home with the assistance of a driver if the doctor deems it safe.

For the first 8 weeks of treatment, there are 12 total sessions twice weekly for the first 4 weeks, and then once weekly for the next 4 weeks. After the initial 8 weeks patients can receive treatment as often as once per week or as infrequently as once per month.

• Drowsiness/grogginess
• Allergic reaction
• Anxiety or panic
• Blood pressure elevation
