What Is Ketamine Therapy?

Ketamine therapy is the supervised medical use of ketamine or one of its derivatives to help treat certain mental health conditions and chronic pain disorders.

Treatment is performed in licensed medical clinics where patients are carefully monitored throughout each session.

The two most common treatment options include:

Ketamine Infusion Therapy

Ketamine is administered through an intravenous (IV) infusion or intramuscular (IM) injection. Most patients receive a series of treatments over several weeks.

Esketamine (Spravato)

Spravato® is an FDA-approved nasal spray containing esketamine for certain forms of treatment-resistant depression. It is administered only in certified healthcare settings under medical supervision.

Important: While Spravato is FDA-approved for specific indications, many ketamine treatments are prescribed off-label. Patients should discuss treatment options with a qualified healthcare professional.

How Does Ketamine Therapy Work?

Ketamine therapy works differently from traditional antidepressants by affecting the brain's glutamate system, which may help improve communication between brain cells and support the formation of new neural connections.

Unlike many traditional antidepressants that target serotonin, ketamine primarily affects the brain's glutamate system.

Researchers believe ketamine helps strengthen communication between brain cells and encourages the formation of new neural connections. These changes may help improve mood, reduce symptoms of depression, and decrease certain chronic pain symptoms.

One reason ketamine therapy has received significant attention is its rapid onset. Some patients report improvement within hours or days, although individual results vary.

Ketamine therapy is generally most effective when combined with an overall treatment plan that may include psychotherapy, medication management, healthy lifestyle habits, and ongoing medical care.

Who May Benefit From Ketamine Therapy?

Healthcare providers may consider ketamine therapy for patients experiencing:

• Treatment-resistant depression

• Major depressive disorder

• Anxiety disorders

• Post-traumatic stress disorder (PTSD)

• Chronic pain conditions, including Complex Regional Pain Syndrome (CRPS)

• Fibromyalgia

• Other conditions evaluated individually by a healthcare provider

Treatment recommendations always depend on an individual's medical history, symptoms, and overall health.

Who Should Avoid Ketamine Therapy?

Ketamine therapy may not be appropriate for everyone. Depending on your medical history, your healthcare provider may recommend alternative treatments.

People who may require additional evaluation include those with:

• Uncontrolled high blood pressure

• Certain cardiovascular conditions

• Active psychosis

• Certain substance use disorders

• Pregnancy or breastfeeding, unless advised by a healthcare provider

• Other medical conditions that may increase treatment risks

A comprehensive medical evaluation helps determine whether ketamine therapy is an appropriate option for each patient.
