For depression, it says an infusion takes about an hour, followed by an hour of rest in the clinic before going home, and most patients receive a series of six infusions over two weeks. Depending on the condition and dose, an infusion can take one to four hours. IV ketamine isn’t FDA-approved for depression and is usually self-pay.
The center treats major depression, treatment-resistant depression, bipolar depression, anxiety, PTSD and OCD, and says ketamine’s rapid action makes it useful for patients with suicidal thoughts. For chronic pain, it lists fibromyalgia, neuropathic pain, chronic back pain, complex regional pain syndrome, phantom limb pain, acute and chronic migraines and postherpetic neuralgia.
Ebrahim Sadighim, MD, a board-certified internist, administers the infusions and monitors patients throughout. He earned his medical degree from Tehran University of Medical Sciences, completed an internal medicine residency at Brookdale Hospital in Brooklyn, and received board certification in internal medicine in 2000. Before joining the center, he spent nearly two decades in private practice in Great Neck.
Before your first infusion, Dr. Sadighim reviews your medications and asks you to avoid eating or drinking for several hours before the appointment. After the infusion, you rest in the clinic until the medication has cleared your system. The center doesn’t publish prices or say whether it accepts insurance, so ask for a quote when you call, and it doesn’t list Spravato or ketamine-assisted psychotherapy.
