The ketamine experience is unlike anything most patients have encountered in conventional medical treatment. It’s not like getting blood drawn or taking a pill. How you prepare for it, and how you care for yourself afterward, can meaningfully affect both the quality of the experience and the durability of the therapeutic benefit.

Here’s what we tell every patient at Mosaic before their first infusion.

Before: The Practical Checklist

Some of this is non-negotiable for your safety. Some of it is about setting yourself up for the best possible experience.

Arrange a Driver — This Is Non-Negotiable

You cannot drive yourself home after a ketamine infusion. Full stop. Ketamine impairs coordination, reaction time, and judgment for several hours after the infusion ends, and this is true even when you feel like you’ve returned to baseline. A responsible adult must be available to drive you home after every session.

If you don’t have someone who can do this regularly, we can talk through options during your consultation. Rideshare services are acceptable only if a trusted person accompanies you (not solo).

Fast for Four Hours

Eat nothing for at least four hours before your appointment. Water and essential medications are fine. Fasting significantly reduces the risk of nausea during the infusion, which some patients experience, particularly in their first session. The discomfort of a light stomach is much preferable to nausea mid-infusion.

Skip Caffeine That Morning

Caffeine can elevate your heart rate and anxiety level, which works against the calm, receptive state you want to be in. Skip your morning coffee on infusion days.

Wear Comfortable Clothing

You’ll be reclined in a comfortable chair for 45–60 minutes. Wear loose, non-restrictive clothing. Leave anything tight or uncomfortable at home.

Build Your Music Playlist

This is more important than it might sound. Music has a profound effect on the ketamine experience; it shapes the emotional and perceptual landscape during the dissociative state in ways that can meaningfully support the therapeutic process.

Bring headphones. Build a playlist in advance rather than trying to find something mid-session. Most patients do best with instrumental music: classical, ambient, or music specifically designed for therapeutic settings. Avoid music with jarring shifts, aggressive lyrics, or anything that tends to trigger anxiety for you. If you’d like playlist suggestions, we’re happy to share what our patients have found helpful.

Set an Intention

This isn’t required, but many patients find it valuable. Before your session, take a few minutes to reflect on what you’re hoping for, not a specific outcome, but an orientation. What would you like to be more open to? What are you ready to let go of? What does relief look like for you?

You don’t need to write it down or share it with anyone. Simply holding a clear intention going into the session can help give the experience direction.

During: What to Expect

Most patients, even those who have read extensively about ketamine, are somewhat surprised by the experience. Here’s what typically happens.

Within a few minutes of the infusion beginning, you’ll notice perceptual shifts: colors may seem more vivid, spatial perception may alter, time may feel stretched or compressed. As the infusion continues, most patients enter a more fully dissociative state: a sense of floating, detachment from the body, and sometimes vivid visual or auditory imagery.

This is the intended therapeutic state, not a sign that something is wrong. You remain conscious throughout. You can communicate with the care team at any time by simply speaking. If anything feels uncomfortable, tell us; we can adjust the rate or stop the infusion.

Let go of the need to control the experience. This is easier said than done for patients who are accustomed to managing their internal states closely, as many people who struggle with anxiety, OCD, or depression tend to be. The therapeutic value of ketamine often comes precisely from the experience of releasing control and allowing something different to emerge. Resistance tends to increase discomfort; openness tends to support a more meaningful experience.

An eye mask can be helpful if external visual stimulation feels distracting. Lie back, let the music carry you, and let the experience unfold.

After: Recovery and Integration

The immediate post-infusion period is predictable. The dissociative effects fade within 30–60 minutes of the infusion ending. You’ll feel gradually more yourself, though some patients remain somewhat spacey or emotionally tender for the rest of the day. This is normal.

Rest That Day

Clear your schedule for the remainder of the day. This is not a day for important meetings, difficult conversations, or complex decisions. Give yourself the gift of a quiet afternoon. Sleep if you can.

Avoid Alcohol and Cannabis

Both can interact unpredictably with the residual neurochemical effects of the infusion and may blunt or disrupt the therapeutic benefit. Avoid them for at least 24 hours after each session.

Journal — Even Just a Little

Many patients experience something during or after their infusion that feels meaningful: an insight, an image, an emotion, a shift in perspective. These experiences can fade quickly if not captured. Even a few sentences written immediately afterward can be valuable to revisit later, particularly in therapy.

You don’t need to analyze what you write. Just record what’s present: what you noticed, how you feel, what came up.

Consider the Integration Window

The 24–72 hours after a ketamine infusion represent what’s sometimes called a neuroplasticity window, a period when the brain appears more receptive to forming new patterns and connections. This is an ideal time for:

  • Therapy: If you work with a therapist, scheduling a session within 48 hours of your infusion can amplify the benefit.
  • Meaningful conversations: Some patients find this period good for difficult conversations they’ve been avoiding.
  • Gentle movement: Walks, stretching, or yoga rather than intense physical activity.
  • Creative expression: Writing, drawing, music, or whatever mode of expression feels natural to you.

What you do in this window matters. It’s not just recovery time; it’s an opportunity.

The Bigger Picture: Integration Over Time

A ketamine infusion is not a cure delivered in a single hour. It’s a catalyst, one that opens a window of neuroplasticity that can be used (or not used) to build something more lasting.

The patients who tend to do best are the ones who treat the infusion series as the beginning of a process, not a standalone event. That might mean combining infusions with therapy, making intentional changes in habits or relationships, or simply approaching their own patterns of thought with more curiosity and less judgment.

The brain is telling you it’s more flexible right now. The question is: what do you want to grow into that space?
