If you have booked your first ketamine infusion, or are considering one, the most common feeling beforehand is uncertainty about what actually happens in the room. Here is the short version of the ketamine infusion experience: you arrive, settle into a private treatment room, and a low dose of ketamine is delivered through an IV over about 40 to 60 minutes while a clinician monitors you. You may feel a calm, dreamlike sense of detachment during the session, which fades afterward. You rest until you feel steady, then a friend or rideshare takes you home. This guide walks through every stage in detail, so there are no surprises on the day.
| What we know
1. A ketamine infusion session at Village TMS lasts about 40 to 60 minutes, delivered in a private treatment room with continuous monitoring of your heart rate and blood pressure. 2. During the infusion, many patients feel a calm, dreamlike sense of detachment called dissociation. This is expected, is not painful, and fades as the medication wears off. 3. You cannot drive afterward. Plan for a friend, family member, or rideshare to take you home, and keep the rest of the day light. |
Before Your Session: How to Prepare
Good preparation makes the ketamine infusion experience smoother. Before your first session, your psychiatrist will have already completed a full consultation, reviewing your medical history, current medications, and goals. On the day itself, a few practical steps help shape a calm ketamine infusion experience.
Eat a light meal a few hours beforehand rather than arriving on a full or completely empty stomach, since ketamine can occasionally cause mild nausea. Wear comfortable clothing. Avoid alcohol the day before and the day of treatment. Most importantly, arrange your ride home in advance, because you will not be able to drive after the session. Many patients also find it helpful to set an intention for the session, a calm sense of what they hope to work on, though this is optional.
Arriving at the Clinic
When you arrive at Village TMS, at 80 5th Avenue in Manhattan, you check in and are shown to a private treatment room. The space is quiet and comfortable, meant to feel calm rather than clinical. You will not be in a busy hospital ward or a shared room.
A clinician will review how you are feeling that day, answer any last questions, and explain what is about to happen. This is a good moment to mention any anxiety you are carrying about the process. Feeling nervous before a first infusion is completely normal, and naming it usually helps.
Starting the Infusion
Once you are settled, a clinician places a small IV line, usually in your arm or hand. This is the only part of the process that involves a needle, and it takes just a moment. Your heart rate and blood pressure are checked to establish a baseline.
The infusion then begins at a low, carefully controlled dose. Ketamine for depression and other mental health conditions is given at a fraction of anesthetic doses. You remain awake and aware throughout. The medication is delivered slowly and steadily over the course of the session, and the clinician can adjust the rate if needed.
During the Ketamine Infusion Session: What the Experience Feels Like
This is the part most first-time patients wonder about. Within the first several minutes, you will likely begin to notice the effects of the ketamine.
The most commonly described sensation is dissociation, a feeling of gentle detachment from your body and surroundings. Patients describe it in different ways: a dreamlike state, a floating sensation, vivid colors or imagery, a sense of distance from their usual stream of thought. Time may feel different. Music, if you choose to listen to it, can feel immersive. For many people, the experience is calm and even pleasant, a quiet that depression and anxiety rarely allow.
It is important to know that this dissociation is expected and temporary. It is not painful. You are not unconscious, and a clinician is present the entire time. If at any point you feel uncomfortable, you can say so, and the clinician can respond. The sensations are strongest in the middle of the session and ease as it ends.
Monitoring and Safety During the Session
Throughout the infusion, a clinician monitors your vital signs, including heart rate and blood pressure. Ketamine can cause a temporary, mild rise in blood pressure, which is one of the reasons continuous monitoring matters. At Village TMS, you are never left alone in the room for the duration of an infusion.
This level of supervision is a core part of safe ketamine treatment, and it is one of the things to look for in any clinic. The clinician is there not only for safety but to help you feel grounded if the experience becomes intense.
After the Infusion: Recovery
When the infusion ends, the dissociative effects begin to fade fairly quickly, usually within 15 to 30 minutes. You will rest in the treatment room or a recovery space until you feel steady and clear-headed. Some patients feel slightly tired, mildly unsteady, or emotionally tender for a short while afterward. This is normal.
You will not be able to drive after the session, so a friend, family member, or rideshare needs to take you home. Plan a quiet rest of the day. Avoid important decisions, work that requires full concentration, and alcohol. Most patients feel back to their normal baseline by the next morning.
Integration: Making the Most of the Experience
The hours and days after a ketamine infusion are when the brain’s neuroplasticity is highest, the period when it is most open to forming new patterns. What you do with that window matters. This is where integration comes in. Reflecting on the session, journaling, gentle activity, and structured ketamine-assisted psychotherapy all help turn the experience into lasting change. Many patients find the integration work is what makes the difference between a temporary lift and a durable improvement.
How Many Sessions Will You Have?
A single infusion is rarely the whole treatment. The standard induction course is six infusions over two to three weeks. Most patients then move to maintenance sessions every four to eight weeks to sustain the benefit. For a fuller picture of how the effects build and last, see our article on how long ketamine lasts for depression. Each session follows the same general shape described above, and most patients find the experience becomes familiar and less daunting after the first one or two.
