Rachel Dalthorp, M.D.

Rachel Dalthorp M.D., Diplomate American Board of Psychiatry and Neurology, developed the Ketamine Infusion Clinic in Oklahoma as a special part of her existing medical practice, Balance Women's Health, to treat those suffering from treatment resistant mood disorders. Dr. Dalthorp is board certified by the American Board of Psychiatry and Neurology.

Dr. Dalthorp received her medical degree from the University Of Oklahoma College Of Medicine. Following medical school, she completed a four year psychiatric residency at the University of Oklahoma Health Sciences Center (OUHSC) where she focused on developing expertise in the assessment and treatment of mood disorders. Dr. Dalthorp augmented her residency education by completing specialized training in psychotherapy provided by the Oklahoma Society for Psychoanalytic Studies. As a Clinical Assistant Professor for OUHSC, Dr. Dalthorp supervises and teaches medical residents. Additionally, Dr. Dalthorp is an expert witness with testifying experience in hormone related mood disorders. 

After becoming increasingly frustrated by the lack of progress for some of her treatment resistant patients, Dr. Dalthorp began investigating ketamine infusion therapy. Following months of research and consultation with experienced physicians, she made the decision to offer this therapy to her patients. Dr. Dalthorp completed her first ketamine infusion treatment in December 2015 and has since completed over 1,500 infusions with significant improvement in symptoms in nearly 75-80% of patients. While ketamine doesn’t work for every patient, when it does, the results are dramatic and life changing.

Dr. Dalthorp is a proud member of the American Society of Ketamine Physicians. 



Ketamine is a medicine developed more than 50 years ago and has been used in general anesthesia for decades in children, adults, and animals. It is a so-called "dissociative anesthetic," which means that it causes an altered state of sensory perception without loss of consciousness. It is used illicitly as a recreational drug, a fact which might bias many of us against considering it potential benefit in medicine.

Recent, exciting news about Ketamine is that a single dose can lead to a dramatic improvement in symptoms of depression, even in patients who have severe, chronic, treatment-refractory mood disorders. Additionally, the nasal spray Spravato (esketamine) was recently FDA approved as a therapeutic option for treatment resistant depression. The Ketamine Infusion Clinic is a provider of Spravato. 

Ketamine has been found to be valuable and highly effective treatment for depression, anxiety, and certain pain disorders.
