Introduction
One of the most common questions new patients ask is, “How long does ketamine stay in my system?” Understanding this helps set expectations and plan post-treatment recovery.
The Science of Ketamine Metabolism
Half-life: Intravenous ketamine has a short half-life—about 2.5 to 3 hours.
Clearance: The liver metabolizes ketamine into norketamine, which is excreted via urine within 24 hours.
Brain activity: Even after the drug clears, its neurochemical effects—especially on NMDA receptors—can continue for days, driving antidepressant benefits.
