What Is Ketamine Therapy for Depression?

Ketamine is a well-established anesthetic that’s now being used off-label in low doses to treat major depressive disorder (MDD), treatment-resistant depression (TRD), bipolar depression, PTSD, and suicidal thoughts.

Unlike SSRIs, which adjust serotonin levels, ketamine acts on the glutamate system, promoting neuroplasticity — or the brain’s ability to grow, adapt, and heal. how long does ketamine work for depression

  • Reduction in suicidal ideation almost immediately
  • Improved energy, sleep, and emotional resilience after 1–3 sessions
