Understanding Ketamine Therapy and Its Contraindications
Ketamine therapy has emerged as a promising treatment for various mental health conditions, including depression, anxiety, and PTSD. Originally used as an anesthetic, ketamine's potential in mental health care has been recognized due to its rapid-acting antidepressant effects. However, identifying individuals who may not be suitable for this treatment is crucial for safety and efficacy.
