What to expect
Before your Ketamine infusion is scheduled, a comprehensive diagnostic assessment will be completed. This will include history of psychiatric disorders and substance use disorders, previous antidepressant treatments, medications, allergies, toxicology screen, and an informed consent process.

Ketamine infusions take place in private rooms in an out-patient basis. The infusion takes about one hour. Patients generally stay another 15-20 minutes before leaving, but you may stay as long as you like. We encourage you to be accompanied for at least the first visit.

During the infusion, you will sit in comfortable reclining chairs and are encouraged to listen to music of your choice from your own playlists. Wi-Fi is available. During the infusion, you will experience some dissociation. Dissociations are not hallucinations, but rather altered reality. Most patients find it pleasurable and non-threatening. If it does make you uncomfortable, the infusion can be stopped. While rarely necessary, medication can also be given which will cease the altered sensations within a minute.

By the time you leave the office, your mental state will be close to normal. Some patients are able to return to work or carry on an otherwise normal day following the infusion. Others prefer to go home and take a short nap. The only restriction after leaving the office is no driving until the next day.

Your improvement in mood will not be immediate. The earliest you might expect to feel better is several hours following the infusion. Doctors are available 24/7 by phone to answer any questions you may have following the infusion.

Monitoring of symptoms
We will regularly monitor your mental health state and any symptoms. We may ask about depression, dissociation, general well-being, side effects, and misuse of the drug.
