What you do before, during, and after a ketamine session shapes how much you get out of it. Whether you’re receiving ketamine in a clinical setting for depression or anxiety, or taking it under medical supervision at home, the choices you make about your environment, mindset, and physical preparation all influence the quality of the experience and its therapeutic benefits. Here’s a practical guide to each phase.
Set an Intention Before You Start
One of the most useful things you can do before a ketamine session is decide what you want to focus on. This doesn’t need to be elaborate. A simple, honest statement about what you hope to explore or release gives your mind a direction when the experience begins to shift your perception. Common intentions include exploring the roots of anxiety, practicing self-compassion, understanding grief, or simply staying present with whatever comes up.
Good intentions tend to be open-ended rather than rigid. “I want to understand what’s driving my self-judgment” works better than “I want to fix my anxiety today.” The goal is to give yourself a loose compass, not a checklist. If you’re working with a therapist, they can help you refine this before your session. Writing your intention down on paper and reading it once before treatment starts can help anchor it.
Prepare Your Body
Nausea is one of the most common side effects of ketamine, and fasting beforehand reduces the risk significantly. Most clinics recommend not eating for at least four to six hours before a session. You can sip water, but a full stomach makes nausea more likely, especially with higher doses.
Certain substances interfere with how well ketamine works. Benzodiazepines like Xanax, Ativan, and Valium, along with alcohol, appear to blunt ketamine’s therapeutic effects. These substances act on the same brain receptor and seem to prevent ketamine from triggering the nerve growth signals that drive its antidepressant benefits. The American Society of Ketamine Physicians notes that the greater the consumption of these substances, the more they diminish treatment outcomes. If you take a benzodiazepine regularly, talk with your prescriber well before your session about how to manage this.
Set Up Your Environment
Your physical surroundings matter more than you might expect. If you’re at home with a prescription, choose a room where you feel safe and won’t be interrupted. Dim the lights or use warm-toned lighting. Research on treatment room environments has found that yellow and white light tend to promote positive mood states and a sense of energy, while blue and red lighting are associated with increased feelings of confusion and low mood. Soft, warm light is your best bet.
Temperature should be comfortable enough that you don’t need to get up and adjust it. Have a blanket nearby, since your body temperature perception can shift during the experience. A couch or recliner where you can lie back safely is ideal. Remove anything you could trip over if you need to stand.
Eye Masks and Music
Two of the simplest tools make a measurable difference. A randomized controlled trial found that combining an eye mask with curated music during ketamine infusion led to deeper engagement with the experience, a stronger sense of connection, increased focus, moments of relief from sadness, and feelings of awe and spiritual insight, compared to ketamine alone. Participants described the experience as more meaningful and emotionally rich.
The eye mask works by reducing visual distraction, letting you turn attention inward. For music, choose something without lyrics, with a slow build. Many clinics use ambient, classical, or specially designed psychedelic therapy playlists. Have your playlist ready before you start so you don’t need to fiddle with your phone once the effects begin.
What to Do During the Experience
Once ketamine takes effect, the most important thing you can do is let go. The onset depends on how it’s administered: intravenous ketamine begins working within seconds and peaks quickly, while intramuscular injection takes three to five minutes. Oral and intranasal forms take longer, typically 15 to 30 minutes before you feel the full effect.
You may feel a floating sensation, changes in how your body feels, or a sense of detachment from your usual thought patterns. Colors, sounds, and emotions can intensify. Some people experience vivid imagery or memories surfacing. None of this is something you need to control. The instinct to resist or analyze what’s happening is natural, but letting the experience unfold without fighting it tends to produce better outcomes.
If you set an intention beforehand, you can gently return to it when your mind wanders, the way you might return to your breath during meditation. But don’t force it. Sometimes the most productive sessions go in completely unexpected directions. Trust the process. If something uncomfortable arises, try to observe it with curiosity rather than panic. Difficult emotions during a session often correspond to meaningful breakthroughs in the days that follow.
Practically speaking, stay lying down. Ketamine significantly impairs coordination and spatial awareness, and trying to walk around increases the risk of falls. Keep a glass of water within reach. If you feel nauseous, slow, deep breathing through the nose can help. Some people find it useful to keep a journal nearby to jot down a few words or images immediately after the peak fades, while the impressions are still fresh.
What Not to Do
Do not drive. Ketamine’s effects on motor coordination last anywhere from 15 minutes to several hours depending on dose and how it was administered, and the impairment is severe enough that it significantly increases the risk of fatal accidents. For the prescription nasal spray form (esketamine), clinics are required to monitor patients for a full two hours after each dose before they’re allowed to leave, and even then you need someone else to drive you home.
Do not take a bath or go near water. Drowning is a documented cause of death among people using ketamine, even in something as seemingly safe as a bathtub. Your ability to gauge danger and coordinate your body is profoundly reduced. A shower the next morning is fine. A bath during or shortly after a session is not.
Avoid screens. Scrolling your phone, watching TV, or reading during the experience pulls you out of the internal space where ketamine does its most valuable work. If you’re using ketamine therapeutically, distracting yourself with entertainment defeats the purpose. Put your phone on silent, face down, and out of reach.
After the Session
The hours immediately following a ketamine experience are sometimes called the “integration window,” and what you do with them matters. Your brain is in a temporarily more flexible state, which is part of why ketamine works for depression: it promotes the growth of new neural connections. Activities that support reflection help solidify whatever insights emerged during the session.
Journaling is one of the most effective integration tools. Write freely about what you saw, felt, or realized, even if it doesn’t fully make sense yet. Don’t edit or judge what comes out. Some people find it helpful to sketch images or describe emotional textures rather than narrating a linear story. If you’re working with a therapist, sharing these notes at your next session gives them valuable material to work with.
Keep the rest of your day low-key. Avoid making major decisions, having intense conversations, or returning to stressful work. Go for a gentle walk if you feel steady enough. Eat something light. Drink plenty of water. Sleep tends to come easily that night, and many people report that the day after a session feels noticeably lighter.
Substances That Reduce Effectiveness
Beyond the pre-session fasting window, your ongoing substance use can shape how well ketamine treatment works over time. Regular benzodiazepine use and frequent alcohol consumption both appear to progressively weaken ketamine’s antidepressant effects by interfering with the same brain signaling pathway ketamine targets. This isn’t just about the day of treatment. Chronic use of these substances seems to create a cumulative dampening effect.
If you drink regularly or take a prescribed benzodiazepine, this doesn’t necessarily disqualify you from ketamine treatment, but it’s something to discuss openly with your provider. In some cases, a gradual taper of benzodiazepines before starting ketamine therapy can improve outcomes. Alcohol is worth reducing or eliminating during any course of ketamine treatment if you want the best results.
