The Benefits of Ketamine Therapy
for Boston Patients
In this patient story, one person shares his experience with treatment.
Ketamine has a growing evidence base for depression. In a 2023 Mass General Brigham trial of 403 patients with treatment-resistant depression, 55% of those who received ketamine experienced sustained improvement in depressive symptoms (Anand et al., New England Journal of Medicine, 2023). For Boston patients searching for an alternative to medications that have not worked, ketamine therapy can offer a faster path to relief. Individual results vary.
Ketamine: An Advanced Approach to Mental Health Treatment
At Cambridge Biotherapies, we provide ketamine therapy to patients across Boston and Greater Boston from our treatment center in Central Square, Cambridge. Ketamine is an evidence-based option for several mood disorders, delivered by our clinical team in a setting built for safety, privacy, and recovery.
Ketamine Therapy: A Beacon of Hope
Ketamine was first introduced as an anesthetic in the 1960s and has been used in clinical and surgical settings for decades. Its fast-acting properties, including pain relief, sedation, and altered states of consciousness, made it a staple of modern medicine long before researchers recognized its potential for mental health treatment.
Ketamine is FDA-approved as an anesthetic. Its use for depression, anxiety, PTSD, and OCD is considered off-label, meaning it is supported by clinical evidence but is not part of ketamine’s specific FDA approval. Off-label treatment is legal and common in medicine when supported by clinical evidence and a clinician’s judgment.
Today, ketamine’s therapeutic role extends well beyond the operating room. Over the past two decades, it has emerged as an important advance in psychiatric care for patients with treatment-resistant depression, anxiety, PTSD, and OCD. This is especially true for those who have not found relief through traditional antidepressants.
Ketamine therapy in Boston, MA is a carefully structured experience. Patients receive a series of intravenous infusions in a private, medically supervised treatment room, monitored throughout by licensed clinicians. The setting is intentionally calm and supportive, with quiet rooms, soft lighting, and a focus on safety, so the focus stays on healing.
Ketamine Therapy for Mood Disorders
Ketamine is an important advance in psychiatric care for mood disorders, including depression, anxiety, PTSD, and OCD. For Boston patients, ketamine therapy at Cambridge Biotherapies™ can offer an evidence-based path to relief for symptoms that have not responded to traditional therapy and medication.

Advantages of Ketamine in Treating Mood Disorders
In clinical research, ketamine has shown the potential to help with mood disorders. For some Boston patients with depression, anxiety, PTSD, or OCD, ketamine therapy may:
- Reduce the severity and frequency of depressive symptoms
- Ease acute anxiety and trauma-related distress
- Support emotional stability and day-to-day functioning
- Improve engagement in therapy by easing the cognitive fog that can accompany severe depression

Conditions We Treat With Ketamine Therapy
Ketamine is FDA-approved as an anesthetic. Its use for the psychiatric conditions described below is considered off-label, meaning it is supported by clinical evidence but is not part of ketamine’s specific FDA approval. Off-label treatment is legal and common in medicine when supported by clinical evidence and a clinician’s judgment.
Depression
For depression that has not improved with standard antidepressants, including treatment-resistant depression, ketamine offers a different approach. Clinical evidence suggests it may help ease depressive symptoms for some patients when other treatments have not been enough. We provide ketamine therapy for Boston patients from our Cambridge treatment center, with professional monitoring throughout each session. Individual results vary.
Anxiety
Ketamine is one of the more closely studied options for people whose anxiety has not responded to standard treatment. Clinical evidence suggests it may help ease acute anxiety and support emotional stability for some patients, particularly alongside ongoing therapy. Sessions take place in a private, calming room at our Cambridge treatment center with professional monitoring. Individual results vary.
PTSD
When trauma-related symptoms have not eased with standard PTSD treatment, ketamine may be worth exploring. Clinical evidence suggests it may help reduce trauma-related distress and support emotional stability, especially when paired with trauma-informed therapy. We provide ketamine therapy in a private, supportive setting with professional monitoring throughout. Individual results vary.
OCD
Ketamine works through a different mechanism than the SRI medications typically used first for OCD, which is part of why it is being studied for patients who have not responded to standard care. Clinical evidence suggests it may help ease obsessive thoughts and compulsive urges for some patients, especially when combined with ongoing therapy. Sessions take place at our Cambridge treatment center with professional monitoring. Individual results vary.
Bipolar Disorder
For depressive symptoms in bipolar disorder, ketamine is used carefully and always as part of a closely supervised plan. Because rapid-acting treatments can affect mood state, it is considered only after a thorough evaluation, and your response is monitored throughout care at our Cambridge treatment center. Clinical evidence suggests it may help ease depressive symptoms for some patients. Individual results vary.
Postpartum Depression
Ketamine may be considered when postpartum depression has not improved with standard treatment. It is used only after a careful evaluation that includes a conversation about breastfeeding and your overall health, and clinical evidence suggests it may help ease depressive symptoms for some patients. Sessions take place at our Cambridge treatment center with professional monitoring. Individual results vary.
