If you are preparing for your first ketamine series, you are likely navigating a mix of anticipation and vulnerability. That is entirely normal. IV ketamine therapy is a highly rigorous medical treatment you are screened by a board-certified physician, your vitals are monitored by a registered nurse, and the intravenous delivery allows your dose to be tailored to your body in real time.
But the clinical protocol is only half of the equation.
The clinical truth: The medicine opens the door, but what you bring to the experience determines what comes back across the threshold.
The intentions you set, the rest you actively protect, and the mental space you carve out afterward are not “extras” around the edges of your treatment they are the treatment. If you are the type of person who researches deeply before making a commitment, this guide is designed to help you approach your first series as a deliberate, profound investment in your healing, rather than just six medical appointments to check off a list.
What This Guide Covers
We won’t be diving into the clinical logistics here (the IV lines, the eye masks, or the clinic timing). If you are looking for a step-by-step walk-through of the physical environment, you can read our companion piece, What to Expect During a Ketamine Infusion.
Instead, this guide is about the practice around the medicine. It is your roadmap for preparing your mind, your environment, and your schedule to get the absolute most out of your upcoming sessions.
How to prepare for ketamine: the week before your first infusion
Preparation begins days before you arrive. The goal is to settle your body and clarify your mind so the treatment meets you in a receptive state.
Tend to your body first. In the days leading up to your infusion, prioritize sleep and hydrate well. Ease back on alcohol and caffeine, since both can leave your nervous system more reactive than you want it to be. Light movement, like a walk through the park or some gentle stretching, helps your body arrive calm rather than wound up. In a city that runs at full speed, giving yourself a slower week before treatment is its own kind of preparation.
Then clarify your intention. Most people skip this, and it matters more than they realize. Intention-setting isn’t mystical; it’s a practical exercise in naming what you’re here to work on. Ask yourself a few honest questions:
- What pattern am I hoping to shift?
- What would relief actually feel like, day to day?
- If this treatment reaches what it’s meant to reach, what changes in my life?
Write the answers down as a baseline, a snapshot of where you are now and where you hope to go. An intention differs from an expectation: it points you in a direction without demanding a specific result, which leaves room for whatever genuinely surfaces.
There is reason to take this seriously. A meta-analysis pooling more than 12,000 psychotherapy patients found that people who expected to improve tended to do better than those who didn’t. Mindset is not the whole story, but it is part of it.
Tell the people who matter. Decide who in your life will know you’re doing this, and who can be available afterward. A trusted person you can talk to in the day or two following an infusion is one of the most useful things you can arrange.
Then the basics. Fast as your care team instructs, arrange a ride home since you can’t drive afterward, and bring whatever helps you feel at ease, like a soft layer or a meaningful object. Planning your trip home from our Midtown clinic in advance, a car service or a friend in the lobby, keeps the end of your session calm. And confirm with your care team whether any of your other medications need adjusting beforehand.
The experience itself: how to be in it
Ketamine brings on a temporary, dreamlike state where you may feel a little detached from your body, your thoughts, or your usual sense of self. For many people that’s the point: it loosens fixed patterns and gives you some distance from the same old mental ruts. How you meet that state shapes how it feels. For more on the mechanics of the session, see our guide to ketamine for depression and anxiety.
Let go rather than grip. Dissociative experiences tend to feel harder when you fight them. If you can soften and let the experience carry you, it usually moves more gently. Resistance is natural, especially the first time. Naming it, as in “I’m bracing,” often loosens it.
Let music guide you inward. Sound is a powerful anchor in this state. Many people find that a curated playlist supports going inward, and your clinical team can offer recommendations if you’d like a starting point.
Return to your intention if you drift. If the experience becomes disorienting, bringing your intention to mind can steady you. You set it for exactly this reason: a quiet thread to follow back.
There is no correct experience. Yours may be profound, gentle, strange, or moving. Some sessions feel significant in the moment; others reveal their meaning only later. All of it is valid, and none of it is a test you can fail.
The integration window: the 24 to 72 hours after each infusion
This may be the most useful section in the guide: the hours after your infusion are when much of the real work happens.
For a short stretch afterward, your brain becomes unusually good at forming new connections. Researchers call this heightened neuroplasticity; the everyday version is simpler: your mind is more open, more able to take in something new and let it stick. Lab research shows these changes begin within hours of a dose. In people, a clinical trial measured brain changes within 24 hours of a single infusion and concluded the window can be used “to augment the antidepressant effects of ketamine by combining it with other therapies.” That open window lasts roughly one to three days, with some effects reaching further.
Think of it this way: the infusion opens a door. Integration is walking through it. Here is how to use the window well.
- Journal before the insights fade. Impressions from the session are vivid at first and slip away fast. Capture them within a day, in whatever form feels natural, whether full sentences, fragments, or a voice memo.
- Schedule therapy within 48 hours. This is when reflective work tends to land differently. Combining ketamine with psychotherapy has stronger support than ketamine alone: a systematic review of 19 studies covering more than 1,000 patients found outcomes were largely positive for adding therapy across depression, post-traumatic stress disorder, and substance use disorders.
- Rest, don’t re-immerse. Resist the urge to plunge back into high-stakes demands; protect a quiet day if you can. If your week tends to swallow you whole, blocking the day after each infusion on your calendar ahead of time is one of the simplest, most protective moves you can make.
A few things to avoid in this window: alcohol, recreational drugs, and unnecessary high-stress situations, all of which may blunt the very signal you’re trying to use.
Between sessions: building on each infusion
A first series is often six infusions, and the time between them is where the work consolidates. Each session can build on the last.
Keep journaling. Track what’s shifting. Which thoughts feel different? Which patterns are loosening their grip? Noticing change helps it take hold.
Stay with your therapy. Integration isn’t a single appointment. Continued therapeutic engagement gives each infusion somewhere to land.
Move your body. Exercise seems to support the same brain chemistry ketamine taps into, so movement may help reinforce the changes the infusion sets in motion. A review of 29 studies found that even a single workout gave that chemistry a boost, and regular exercise strengthened the effect. A daily walk counts.
Let the opening reach your relationships. Healing rarely stays neatly inside your inner life. Allow it to soften how you connect with the people around you, and let those relationships support you back.
Approaching healing with intention
The people who get the most from ketamine therapy treat the whole series as a healing practice, not a calendar of appointments. The medicine is a catalyst, and it works best when it has something to catalyze.
You don’t have to do any of this perfectly. Miss a journal entry or have a stressful week and the treatment still works, because healing is cumulative. Preparation simply tilts the odds in your favor, and you have more influence over the outcome than you might think.

Frequently asked questions
How do I prepare for ketamine therapy the week before? Focus on rest, hydration, and easing off alcohol and caffeine, then clarify your intention by writing down what you hope to shift and what relief would feel like. Arrange a ride home and someone to check in with afterward.
