Overview
How IM ketamine works
With intramuscular (IM) dosing, ketamine is injected into a muscle, usually the upper arm or shoulder. It's absorbed quickly and avoids the need for an IV line.
IM ketamine is commonly used in ketamine-assisted psychotherapy and for booster sessions, and visits tend to be shorter than infusions.
