How to Take Ketamine at Home: A Physician's Step-by-Step Guide

This guide is narrowly about technique — how to actually take the medication during a prescribed session. Buccal hold time, dose timing, what to do with the saliva, meal spacing, posture, aftercare. It assumes you already have a prescription and have done the clinical homework.

Looking for a broader guide? If you're researching what at-home ketamine therapy is, who qualifies, what it costs, and how the whole program works — start with our at-home ketamine therapy guide. That's the right entry point for "at-home ketamine" questions; this page is the follow-up for "once I have a prescription, how do I actually take it."

For background on every route ketamine can be administered (IV, intranasal, sublingual, IM, oral), see all the ways ketamine can be given.

Preparation

Fasting for Six Hours

Before your ketamine session, it's essential to fast for at least six hours. This ensures that the ketamine is absorbed more effectively and minimizes the risk of nausea and vomiting--risking aspiration--during your session.

Avoiding Sedative Medications

Ensure that you are not taking any sedative medications or alcohol that might interact with ketamine, as this could lead to adverse effects.

Set the Right Setting

Create a comfortable, safe, and calming environment in your home. A quiet, dimly lit room with a comfortable bed or couch can be an ideal space for your session. You may like to light a candle or burn incense.

Keep Out of Water

No hot tubs, bathtubs, swimming pools. You can drown.

Music

Play relaxing or meditative music to set a soothing atmosphere. Some recommend classical music such as Bach.

Trusted Companion

It is essential to have a close and trusted friend nearby who can provide emotional support and assist you if needed.

Monitor Blood Pressure and Oxygen Levels

If you have a history of high blood pressure, check your blood pressure before, during, and after the session. For those with respiratory issues, wear a pulse oximeter to monitor your oxygen levels during the treatment.

Use an Eye Mask

It is recommended to wear an eye mask during your ketamine session. It helps enhance the introspective experience and block out external visual distractions, allowing you to focus on your thoughts and feelings.

The Ketamine Ingestion Process

Taking the Ketamine Tablet

When ready, take the prescribed ketamine tablet and place it under your tongue. Ketamine tablets are designed to dissolve, so try to keep it in your mouth for as long as possible.

Managing Residue

The taste may be challenging, and saliva may accumulate, leading to unintentional swallowing. Spitting out the residue after 10 minutes may help reduce nausea. Some choose to swallow the residue which will prolong the effect. Having a cup handy is helpful.

During The Session

Prepare for Bed Rest

Expect to be lying in bed for at least two hours or more during the peak effect of the medicine. Ketamine's effects can vary, but it often induces a dreamy or dissociative state. During this state it is unsafe to walk around without assistance. Take a moment now to use the bathroom before the medicine sets in.

Minimize Distractions

Turn off your phone or put it on airplane mode. This is your time for self-care and introspection. Put on your eye mask. Relax and focus on your breath.

Onset and Peak

Effects typically begin within 10-20 minutes of ingestion. The peak of the experience--when dissociation and sensory changes are strongest--usually occurs 40 to 60 minutes after the dose and lasts for about 30-60 minutes and then gradually wears off.

Sensations and Experience

Expect to enter a dreamy or deeply dissociative state. Common sensations include a shift in perspective, altered sense of time and space, and feeling detached from your body. This is safe and expected.

Session Duration

Commit to a total session time of at least four hours from the moment you ingest the medicine. During this time, you will not be available for work or child-care related tasks.

Balance and Walking Issues

As ketamine can affect your coordination and balance, do not attempt to walk or move around during the peak of your session. It is advisable to remain lying down to prevent accidents or falls. If you must move, use extreme caution and have your trusted companion assist you.

Nausea Management

Be prepared for potential nausea and vomiting during the session. Your healthcare provider may prescribe anti-nausea medications to manage this issue.

Aftercare

Allow Time for the Effects to Wear Off

Ketamine's full effects typically wear off four to five hours after ingestion. Ensure that you remain at home during this period and avoid driving or operating machinery, as ketamine can impair coordination and cognitive function.

Emotional Support

Have a trusted friend or family member available to provide emotional support and assistance as you come down from the ketamine experience.

Integration

Integration: Take time and make the effort to integrate and implement change. Introspect on the experience and write or record what thoughts and feelings arise. Start a practice of spending time with yourself in nature, walk, meditate, really any practice that focuses on self improvement.

Conclusion

Ketamine therapy has shown promise in helping individuals with mental health challenges. While some opt for at-home treatment, it is essential to prioritize safety and proper preparation. Following these guidelines for at-home ketamine treatment can help ensure a comfortable and secure experience, promoting the potential benefits for your mental health while minimizing any associated risks. Always consult with a healthcare professional before beginning ketamine therapy to ensure it is appropriate for your specific needs.

Remember that safety, comfort, and a supportive environment are key to a successful ketamine treatment.

Frequently Asked Questions

How long does ketamine take to kick in?

For sublingual ketamine (troches and ODTs taken at home), onset typically begins 10-20 minutes after the dose, with the peak experience at 40-60 minutes. IV ketamine is faster (5-10 minutes to onset). The slower sublingual onset is actually a feature, not a bug — it gives you a more controlled, gradual entry into the dissociative state, which most patients find easier to manage at home.

How long does a ketamine session last?

The active dissociative experience lasts 90-120 minutes total: 10-20 minutes to onset, 30-60 minutes at peak, then a gradual comedown. After that, you'll feel pleasantly heavy and a little spaced out for another 1-2 hours. Plan to commit at least 4 hours from the moment you take the dose, with no driving, no work, and no important conversations during that window.

Can you swallow ketamine instead of holding it under your tongue?

You can, but the bioavailability drops dramatically. Swallowed ketamine loses 60-80% of the dose to first-pass liver metabolism, which is why sublingual administration exists in the first place. The whole point of holding the troche or ODT under your tongue for 10-15 minutes is to absorb the drug through the sublingual blood vessels before it can be swallowed and broken down.

What does ketamine feel like?

At therapeutic doses, most patients describe a quiet, dreamlike state with distance from anxious thoughts. Some experience visual patterns, a sense of floating, time distortion, or feelings of detachment from the body. The goal is gentle dissociation — distinct enough from yourself to see thoughts from outside, not so far that you panic. The subjective experience differs significantly from recreational ketamine use, where doses are higher and the context very different.

How often should you take ketamine for depression?

The standard induction protocol is 6-12 sessions over 4-8 weeks, typically twice weekly during the early phase. After induction, most patients transition to maintenance dosing — every 1-4 weeks depending on response. Your prescribing physician adjusts frequency based on how you're responding, and there's no universal protocol that fits every patient.

Can you drive after taking ketamine?

No. Ketamine impairs coordination, judgment, and reaction time for at least 4-5 hours after the dose, often longer. Don't drive, operate machinery, or do anything safety-critical until the next day. Most patients schedule sessions for evening or weekends precisely so this isn't a concern.

What should you do if you feel uncomfortable during the session?

Focus on slow breathing through the nose. The intensity is always temporary — it builds over 15-30 minutes and fades within an hour of the peak. If you can lie still, keep your eye mask on, and stay with the breath, the experience usually settles within minutes. Have a trusted person reachable nearby (not necessarily in the room with you) who can check in if you need help.
