Ketamine is a cutting-edge psychiatric treatment being used to target severe medication and treatment resistant depression. Ketamine has been widely used as an anesthetic for minor procedures since the 1960s.  In many countries, it is used by first aid response workers when dealing with minor trauma.  The safety of Ketamine is such that it is used as outpatient anesthetic by non-physicians.  The dose used to treat depression is about one quarter (1/4) of anesthetic dose.

While it has not yet been formally approved by the FDA, there are now many studies that demonstrate that Ketamine infusions for depression may be an effective and rapid treatment option. Benefits may occur after only one treatment, though typically an initial course of several treatments are required for a more robust response. 

Our Ketamine infusions take place at our convenient midtown New York City location in a private room with state-of-the-art medical equipment under the supervision of Dr. Cohen. Each infusion takes about one hour and is administered intravenously.

The American Psychiatric Association (APA) Council of Research Task Force on Novel Biomarkers and Treatments has issued a consensus statement that “ketamine may be beneficial to some patients with mood disorders,” and encouraging doctors to weigh benefits and risks of this therapy with potential patients based on available data.
