The short answer: ayahuasca preparation involves dietary restrictions to avoid tyramine-rich foods, a medically supervised review of your current medications, adequate sleep and hydration, and time set aside for mental preparation. The dietary and medication pieces exist because ayahuasca contains MAO-inhibiting beta-carbolines, which can interact with certain foods and drugs. This article is educational and is not medical advice; your preparation plan should be reviewed with your own physician, especially if you take any prescribed medication.
Preparation is often described in soft, general terms — eat clean, get rest, set an intention — but the most consequential parts of it are quite specific and grounded in ayahuasca's actual pharmacology. Because the medicine contains compounds that inhibit monoamine oxidase, an enzyme responsible for processing both certain medications and certain dietary compounds, the preparation period is not simply a wellness ritual. It is the window in which real interaction risks are identified and managed, ideally with enough lead time that a medication adjustment, if one is needed, can be handled safely by the physician who prescribed it. The ten points below separate the dietary and medical preparation that carries genuine safety weight from the physical and mental preparation that supports a smoother experience but is not itself a clinical safeguard.
1–3: The Dietary Foundation
1. Tyramine-rich foods are restricted before a ceremony. Aged cheeses, cured and smoked meats, fermented products, and certain alcoholic beverages are commonly restricted because of ayahuasca's MAO-inhibiting effect. Our ayahuasca diet guide lists specifics.
2. The restriction window typically spans one to two weeks. Programs vary in exact timing, so ask for a written schedule rather than relying on general guidance found online.
3. Reducing caffeine, sugar, and processed food is commonly recommended. This is generally framed as supportive preparation rather than a strict medical requirement, but it is worth asking your program what they specifically advise.
The reasoning behind the tyramine restriction deserves a bit more explanation than a simple list of foods. Tyramine is a naturally occurring compound that forms as proteins break down during aging, curing, fermentation, and smoking. Under normal circumstances, monoamine oxidase in the gut and liver processes tyramine efficiently, keeping it from building up. When MAO activity is inhibited, as it is during and for some time after an ayahuasca ceremony, that processing slows down, and tyramine can accumulate to a degree that would not occur otherwise. This is the same underlying mechanism responsible for the well-known dietary restrictions associated with pharmaceutical MAO-inhibiting antidepressants, and it is treated with the same seriousness in a responsible ayahuasca preparation protocol. Common foods on a restriction list include aged cheeses, cured meats like salami and prosciutto, smoked or pickled fish, sauerkraut and other fermented vegetables, soy sauce and miso, overripe fruit, and most forms of alcohol, particularly tap beers and certain wines.
A practical detail worth noting is that the restriction window generally extends slightly beyond the ceremony itself, not just beforehand. Because MAO inhibition from ayahuasca does not end the instant a ceremony concludes, many programs advise maintaining dietary caution for a day or two afterward as well. Ask your specific program for the exact after-ceremony window they recommend rather than assuming it ends the moment you leave the ceremonial space.
4–6: Medication Review and Physician Coordination
4. A full medication review must happen before you are approved. SSRIs, SNRIs, stimulants, and several other medication classes can interact with ayahuasca's MAO-inhibiting compounds. Disclose everything you take, including over-the-counter supplements, during intake.
A complete list means everything — not just the medications you consider significant, but occasional over-the-counter drugs, herbal supplements, and anything you take intermittently rather than daily. People sometimes leave out supplements or "natural" products on the assumption that they don't count as medication, but several supplement categories are also relevant to MAO-inhibition risk. The safest approach is to write down literally everything you take, however minor it seems, and let the reviewing physician decide what is and isn't relevant, rather than making that judgment yourself.
5. Any medication adjustment must be physician-supervised and planned early. If your prescribing physician determines a change is appropriate before a ceremony, that change should follow a slow, supervised schedule specific to the medication involved — never a sudden stop initiated on your own.
6. Coordination between your home physician and the retreat program is a good sign. Programs that request records or a brief consultation with your prescribing doctor are treating the interaction risk with appropriate seriousness. See our preparing for ayahuasca guide for more on this coordination.
Good coordination often looks like a written summary from your physician, a signed release allowing the retreat's medical staff to speak with your doctor directly, or a short consultation between the two. This isn't about your home physician needing to approve of the retreat itself; it's about the retreat's medical team having the clinical context they need to make an informed decision about your candidacy and to plan appropriately around your specific medication history.
The medication classes most frequently discussed in connection with ayahuasca are SSRIs and SNRIs, prescribed widely for depression and anxiety, along with stimulant medications used for attention conditions, certain migraine medications, some over-the-counter cold and cough preparations, and a handful of dietary supplements marketed for mood or energy support. This is not an exhaustive list, and it should never be treated as one; the point of the physician-led review is precisely that a qualified clinician, not a general online list, makes the determination for your individual case, based on the specific medication, dose, and how recently you have taken it. A medication that is a genuine concern for one person may be a non-issue for another depending on dosage and timing, which is exactly why self-diagnosis from a checklist is not a substitute for a real physician review.
It is worth repeating, because it is easy to underestimate: no responsible program will tell you to unilaterally stop a prescribed medication on your own initiative in order to attend a ceremony. If a change is warranted, it is planned in coordination with your prescribing physician, on a schedule that accounts for the specific medication's half-life and withdrawal profile, and with enough lead time before the ceremony that the change has time to take full effect. Some medications require weeks of tapering; others may not require any change at all. This variability is one more reason the review has to happen early and has to involve someone with the clinical training to make that judgment, rather than being decided based on general information found in an article like this one.
7–8: Physical Readiness and Screening
7. Hydration and sleep matter in the days leading up to a ceremony. Arriving well-rested and adequately hydrated is commonly recommended as part of general physical preparation.
Travel itself can undermine this without anyone intending it to — time zone changes, dehydration on long flights, and disrupted sleep in the days before a ceremony can leave someone more depleted than they realize going into a long ceremony night. Building in a day or two to rest and adjust after travel, rather than arriving and going straight into ceremony preparations, is worth discussing with your program if your schedule allows for it.
8. Medical screening should happen before you finalize travel. Cardiac history, psychiatric diagnoses, and pregnancy status are typically reviewed as part of intake, and a program should be willing to decline a candidate when a genuine contraindication is present.
A thorough intake process typically asks about personal and family cardiac history, any history of psychiatric hospitalization or diagnosed conditions such as bipolar disorder or psychosis, current pregnancy or the possibility of it, and any recent major surgery or acute illness. This is not an attempt to disqualify people unnecessarily; it is a recognition that ayahuasca is contraindicated for certain conditions and that a program licensed by COFEPRIS, Mexico's federal health regulator, has an obligation to screen for those contraindications rather than accept every applicant who wants to attend. A program willing to decline a candidate, or to require additional medical clearance before approving one, is generally a program treating physical and psychiatric screening as more than a formality.
9–10: Mental Preparation and What Comes Next
9. Setting an intention is a common part of preparation. Many practitioners recommend taking time beforehand to reflect on what you hope to explore, though this is a personal practice rather than a medical requirement.
10. Preparation extends into planning for integration afterward. Ask what support is available once the ceremony concludes, including guidance on resuming any paused medication under physician direction.

A Short Preparation Checklist
- Written dietary restriction schedule covering tyramine-rich foods and alcohol
- Complete medication and supplement list disclosed to a physician
- Any medication adjustment planned and supervised by your prescribing doctor
- Confirmed screening for cardiac, psychiatric, and pregnancy contraindications
- Hydration and sleep prioritized in the days before travel
- Time set aside for intention-setting and mental preparation
- A defined integration plan for after the ceremony
- Complete disclosure of every medication and supplement, however minor it seems
- Time built in for rest and adjustment after travel, before the ceremony itself
It helps to put your preparation plan in writing rather than keeping it as a loose mental list. A simple document noting your dietary restriction start date, every medication and supplement you take, any adjustment timeline agreed with your physician, and the name of who to contact at your program with questions gives you something concrete to refer back to as your ceremony date approaches, and something you can also share with your prescribing physician so everyone involved is working from the same information.
It is also worth being honest about the limits of preparation itself. No amount of dietary discipline, rest, or intention-setting changes the fact that ayahuasca is a potent substance that affects each person differently, and no program can promise a particular outcome from the experience. Careful preparation reduces specific, known risks — the interaction risk from MAO-inhibition being the clearest example — but it does not guarantee comfort, insight, or a smooth night. Approaching preparation with this honest framing, rather than as a formula for a certain kind of outcome, tends to serve people better once they are actually in ceremony.
Preparation for ayahuasca is not a single checklist item but a layered process spanning weeks, involving your own physician as much as the retreat program itself. Treating the dietary and medication pieces with the seriousness their underlying pharmacology deserves, while allowing the physical and mental preparation to unfold in whatever way suits you personally, is a reasonable way to approach the weeks before a ceremony.
