St. Mark's Institute for Health
St. Mark's Institute for Health in New York City offers ketamine therapy as a transformative treatment for depression, anxiety, PTSD, bipolar disorder, and chronic pain, tailored to each individual's needs. Ketamine is administered in a controlled environment via IV infusion or intranasal spray, allowing rapid improvement in symptoms, often within hours or days.
A medical doctor monitors the entire treatment, and during ketamine-assisted therapy a therapist is also in the room. Ketamine creates a dream-like state in which patients remain fully conscious and able to participate in therapy, with sessions lasting about one to one and a half hours, followed by recovery time until medically cleared.
The practice also offers Spravato nasal esketamine, approved by most insurances, along with therapy and medication management, taking a compassionate, personalized approach to mental health care.
