Is ketamine only used to treat depression? What can it be used to treat?

Ketamine has been most well-researched and well-studied for depression that has not responded to other forms of treatment, and this is the most common and strongest indication for ketamine treatments. For this reason, treatment-resistant depression is the condition for which Being Health offers ketamine treatments. 

At the same time, some research has been done into the potential benefits of ketamine treatments for conditions, such as anxiety disorders, PTSD and OCD. That said, research is rather limited. For this reason, consideration of ketamine treatments for these conditions would be made on a case-by-case basis and particularly in the context of ongoing psychotherapy that is oriented toward treatment of these conditions.
