KETAMIND is New York City's premier psychiatric ketamine clinic. KETAMIND offers an innovative and simple non-invasive ketamine nasal spray. Ketamine is one of the most recent and promising options for the treatment of depression, OCD and PTSD. This anesthetic agent, in use for decades, has demonstrated to be effective in rapidly alleviating depressive symptoms at a sub-anesthetic dose with minimal side effects. Unlike the weeks or months for a response using conventional antidepressants, ketamine may provide results quickly, often within hours.
