Who is a good candidate for ketamine treatment for OCD?

A good candidate for ketamine treatment for OCD is: someone who has persistent, intrusive thoughts or compulsive behaviors that have not improved or plateaued with standard oral medications. Ketamine may be appropriate for individuals who: Have treatment-resistant OCD, meaning they’ve tried multiple medications (such as SSRIs) or Exposure and Response Prevention (ERP) therapy without enough relief Experience symptoms like depression or anxiety that significantly interfere with daily life or functioning Cannot tolerate the side effects of traditional OCD medications Are motivated to continue therapy or ERP while receiving ketamine, as ketamine can enhance treatment response

Ketamine Therapy for
OCD

More than 2 million Americans live with obsessive-compulsive disorder (OCD), and many patients do not achieve full relief with traditional treatments such as talk therapy or medication. Ketamine therapy offers a new approach for those seeking lasting relief.

Understanding OCD

What is OCD and how is it treated?

Obsessive-compulsive disorder (OCD) is a chronic mental health condition characterized by recurring, unwanted thoughts and repetitive behaviors. While many patients respond to treatment, others continue to experience persistent symptoms that interfere with daily life.

Key symptoms

The science

How ketamine treats OCD

“For many patients, relief begins within hours of their first session — not weeks.”

Unlike traditional antidepressants that can take weeks or months to work, ketamine targets the brain’s glutamate system to help form new neural connections. This process can disrupt entrenched thought patterns and repetitive behaviors, allowing the brain to shift away from obsessive-compulsive cycles.

Studies show ketamine can rapidly reduce OCD symptoms, with some patients experiencing improvement soon after treatment.

For many patients, this offers a new option when traditional therapies have not provided sufficient relief.

FAQs

Ketamine reduces obsessive thoughts and compulsive behaviors in patients living with OCD by blocking NMDA receptors and increasing the neurotransmitter glutamate, which promotes neuroplasticity and neural regeneration. This works differently than traditional medications by producing a surge in neuroplasticity that can help the brain form new, less rigid patterns of thinking and behavior, which may reduce obsessive thoughts and compulsive responses and help people feel less “stuck”.

Many patients experience symptom relief within hours to days after a treatment, and some report early improvements after the first session. A typical induction course of ketamine for OCD lasts three to four weeks with six to eight sessions depending on the type of ketamine, and full benefits often emerge across that period. Individual responses vary in terms of timeline and extent.

Most patients continue their SSRI while receiving ketamine therapy for OCD. Our physicians will review your medication list during the initial consultation and coordinate care with your prescribing clinician to ensure safety and optimize effectiveness.

Ketamine infusions are off-label and therefore not covered by insurance. For patients who also have treatment resistant depression, Spravato® (esketamine) may be an option.

Spravato is FDA-approved and many insurance providers will cover it for depression related to OCD. Keta Medical Center will work with your insurer to complete the required prior authorization and provide documentation of your treatment history. Superbills for patients to submit to insurance providers are available.
