Ketamine Therapy for Post-Traumatic Stress Disorder: What You Should Know

In 2025, a large number of Australians will live with post-traumatic stress disorder (PTSD), a debilitating condition triggered by traumatic events like combat, assault, or natural disasters. For those with treatment-resistant PTSD, where traditional therapies like SSRIs or psychotherapy fall short, ketamine for PTSD offers a promising alternative. Clinics like Mind Connections Specialist Health Services are exploring ketamine PTSD treatments to provide rapid relief.

Understanding Ketamine Therapy for PTSD

Ketamine, originally an anesthetic, is used off-label at low doses (0.5 mg/kg IV) to treat PTSD, often via intravenous infusions over 40 minutes in clinical settings. It targets NMDA receptors, boosting glutamate and synaptic connectivity in brain regions like the hippocampus and prefrontal cortex, reducing fear and traumatic memories. Recent studies show ketamine achieves symptom reduction within a day, especially when paired with therapies like prolonged exposure (PE).

Why Consider Ketamine for PTSD?

Addresses treatment-resistant PTSD unresponsive to SSRIs or therapy.
Offers rapid symptom relief, often within hours to days.
Shows promise in reducing suicidal ideation and co-occurring depression.

Pros and Cons of Ketamine Therapy

Pros

Effective for Treatment-Resistant PTSD:

Studies show success in alleviating symptoms in patients unresponsive to antidepressants or therapy, offering hope for chronic cases.

Enhances Psychotherapy:

Ketamine PTSD therapy, paired with PE or TIMBER, boosts efficacy by enhancing memory reconsolidation, sustaining benefits for weeks.

Reduces Co-occurring Depression:

Ketamine alleviates depression and anxiety in 60–70% of PTSD patients, reducing the need for multiple medications.

Minimal Long-Term Side Effects:

When supervised, ketamine has transient side effects like dizziness, unlike SSRIs’ systemic effects. Patients tolerate it well with monitoring.

Cons

Short-Term Effects:

Benefits may fade within weeks, requiring repeat infusions costing $600–$800 each, per Harvard Health, challenging for long-term management.

Potential Side Effects:

Dissociation, nausea, and elevated blood pressure occur during infusions, requiring 1–2 hours of monitoring, which may unsettle some patients.

Requires Medical Supervision:

Ketamine for PTSD needs psychiatrist oversight and pre-treatment screening, delaying access in areas with limited specialists.

Effectiveness and Safety

Ketamine for PTSD achieves symptom reduction within hours. It’s particularly effective for veterans and those with co-occurring depression, reducing suicidal ideation.

Side effects like dissociation or nausea are transient and managed in-clinic. Esketamine (Spravato), an FDA-approved nasal spray, shows similar benefits but requires strict supervision. Costs range from $600–$800 per infusion, with 6–8 sessions recommended, though private insurance may offset expenses in Australia. Always consult a psychiatrist to assess eligibility, especially for those with heart conditions or substance use history.
