IV Ketamine Therapy

IV Ketamine Therapy is a medical treatment that uses low doses of ketamine delivered through an intravenous (IV) drip to help manage certain mental health conditions and chronic pain.

IV ketamine therapy is a promising, fast-acting option especially for people who haven’t found relief with traditional treatments. However, it should always be done under strict medical supervision.
