What to expect at your first ketamine infusion

Eat lightly and stop food four hours before; sips of water are fine until arrival. Take your usual medications unless the clinic told you to hold one (benzodiazepines and lamotrigine can blunt the effect and are sometimes paused). Arrange a ride.

What does a ketamine infusion feel like?

Within ten minutes, a sense of detachment from your body and surroundings, changes in perception of light and sound, and sometimes emotional release. Anxiety is common in the first few minutes and usually passes. Nausea affects about a third of patients; ondansetron is typically available. Blood pressure rises modestly and is watched.

What happens after the infusion?

Tiredness, mild headache and unsteadiness for a few hours. No driving, no important decisions, no alcohol that day; Driving and monitoring rules for Spravato and ketamine explains the wait. Mood improvement, when it happens, often appears within 24 hours of the first or second infusion and builds over the series.

How can you get the most from each infusion?

Some clinics offer integration sessions with a therapist after each infusion; even journaling for ten minutes afterward helps people notice and keep gains. See ketamine-assisted psychotherapy and the ketamine therapy guide.
