IM Ketamine Injection Clinics

How IM Ketamine Injection Works

Intramuscular (IM) ketamine is a single injection into the shoulder or thigh rather than an IV drip. It reaches high blood levels quickly, requires less equipment and setup time than an infusion, and is offered by many psychiatric practices as a simpler, often less expensive alternative with broadly similar effects.

The trade-off versus IV is precision: an IM dose can't be adjusted once given, so clinics typically titrate across sessions instead of within one. Session structure otherwise mirrors IV programs — an induction series followed by boosters, with in-office monitoring and a no-driving rule after each visit.

What to Expect at Your Appointment

Visits are usually shorter than IV appointments — the injection itself takes seconds, the dissociative experience peaks over 20–45 minutes, and clinics monitor you until effects settle. Expect roughly 60–90 minutes on site.
