Ketamine confusion
The rule on controlled substances has also caused some consternation, especially given that it does not differentiate between racemic ketamine and esketamine, said Lisa Marie Harding, MD, vice president of the board of the American Society of Ketamine Physicians, Psychotherapists & Practitioners.

Esketamine (Spravato) is approved by the Food and Drug Administration and, under a Risk Evaluation and Mitigation Strategy, can only be administered in FDA-monitored treatment facilities. Racemic ketamine is being prescribed – often for home use – with almost no regulatory oversight.
Dr. Harding, who is an approved Spravato provider and also administers intravenous ketamine in her practice, does not believe that ketamine should be used at home without supervision.
“I had a patient who had a very powerful dissociative experience in my office earlier this week,” Dr. Harding said in an interview. One of her staff asked what would happen if the patient had experienced that at home. “We don’t know. Nor do we want this to happen,” said Dr. Harding.
However, the DEA proposal would continue to allow for home use, at least initially. “If it’s open to interpretation, those people that prescribe ketamine for home use can use that leeway to then continue to do it,” she said. “That is not safe.”
Dr. Harding approves of the proposed DEA requirement for face-to-face visits. “It’s good patient care,” she said. But she wants the administration to adjust the rules to make it harder to offer home ketamine therapy.
“Lots of people are using racemic ketamine off-label for treating depression with success but doing it in treatment settings that are appropriate,” said Dr. Harding.
Dr. Hurley and Dr. Harding report no relevant financial relationships.
