Ayahuasca is an extraordinarily profound medicine that has assisted hundreds of thousands across the world to heal from a variety of health problems.
However, it’s not suited for every issue and every person. There are various supplements, medications and health conditions that are contraindicated with Ayahuasca and could cause much more harm than good when combined.
Please carefully read through the following page which contains a large list of contraindicated medications and health issues. This list can never be entirely complete however because there are always new medications being manufactured and sold on the market.
It is very important that you honestly disclose, in confidence, any known physical or mental health conditions and use of medications, past and present, when applying to one of our Ayahuasca retreats in Peru.
If you decide to ween off any medications because they are contraindicated with Ayahuasca, it is very important that you ask permission and discuss this with your doctor first.
By attending one of our Ayahuasca retreats in Peru, you are declaring that you are in a physical and mental condition appropriate to the ceremonies and activities described in our retreat info page and you are agreeing to our Guest Guidelines & Commitments, here.
It’s essential to seize taking the following substances and give your system sufficient time to remove them from the body, before you attend an Ayahuasca retreat. Please consult your doctor if you are in any doubt: you certainly should not suddenly stop taking prescribed medications (especially antidepressants) without consulting your doctor.
It is not safe to work with Ayahuasca if you take the following medications or have any of the following health conditions:
- Any medication that contains Monoamine Oxidase Inhibitors (MAOI’s) – these are known to cause dangerous side effects when taken in conjunction with ayahuasca. It is critical that you stop taking these medications under the supervision of your doctor and allow plenty of time for your system to be cleared of these substances before working with ayahuasca.
- Any medication which has an effect on the serotonin system, including Selective Serotonin Re-uptake Inhibitors (SSRIs) (i.e. antidepressants such as Wellbutrin, Prozac, Zoloft, Effexor, etc). Combining these medications with ayahuasca can induce serotonin syndrome – far more severely than with foods containing tryptophan, and with potentially fatal results. We require guests discontinue taking SSRI medications under the supervision of their doctor prior to applying for a retreat to allow the system to clear in time. Some of these drugs may cause side effects when discontinued, and plenty of time should be allowed for these to subside. Do not abruptly stop taking any medication without discussing the matter with your doctor. Please note that the herbal antidepressant St. John’s Wort (hypericum perforatum) also must not be taken within 2 weeks of working with ayahuasca.
- Other medications that must be discontinued are decongestants, cold medications, allergy medications, antihistamines, sedatives, tranquilizers, amphetamines (including Adderall), some hypertensive medications, sympathomimetic amines (including pseudoephedrine and ephedrine), carbamazipine, methylphemidate (Ritalin), macromerine, phenelanine, tyrosine, tryptophan, asarone/calamus, some asthma inhalers, and diet pills.
- Although ayahuasca has not been found to cause psychosis or other psychiatric disturbances, it can be dangerous to those with a history of psychological problems. Please tell us if you have any history of mental health conditions.
- If you are pregnant or have a heart condition or chronic high blood pressure, we will not be able to accommodate you for a retreat.
Advice on drugs and medications to avoid when working with Ayahuasca:
- This is a comprehensive information page of medical, botanical, and nutrition interaction guidelines provided by Ayahuasca Forums.
- In general, from an Amazonian plant healers’ traditional perspective, when a patient or an apprentice is working with medicinal plants, especially ayahuasca and some other important medicinal plants like chirisanango, huayracaspi, Toé etc., it is preferable to not take any other substances or medicines, as it may cause cutipado, or, in other words, interfere with the plant’s energy and provoke unwanted reactions.
- It is important to suspend any kind of psycho-pharmacy and pharmaceutical depression treatments under the supervision of your doctor between 14 to 60 days before drinking ayahuasca. We will provide more specific requirements upon receipt of your medical information and application for a retreat.
- Before applying to attend a workshop, it is important that we have full disclosure of all medications/drugs and the length of time taking them.
- Guests/volunteers with hepatic conditions must first consult with us and provide more information about their condition. People with tuberculosis must not take ayahuasca.
Family History of Severe Mental Illness
The right and appropriate use of ayahuasca in the tradition facilitated by El Camino Sagrado in Peru has been specifically utilized with significant results for the support and improvement of psychological trauma and its resultant symptomatology. At the same time, potential guests with a close / strong family history of bipolar mood disorder, schizophrenia, and depersonalization should realize they are at an increased risk for the expression of these symptoms, and it is conceivable (although highly unlikely) that ayahuasca can unmask such symptoms in predisposed individuals. Consequently, people who meet this criteria should undertake this type of work with due consideration and at their own risk.
If you have history of psychosis in your family, we would firstly need to ascertain that you:
- Have no direct history of major issues of mania, psychosis, or depersonalization
- Have not previously taken any medication for these conditions
- Are not currently taking any psychiatric medication
Provided none of these three points are aplicable, then we may be able to accommodate you for a retreat. However, please inform us if you have any history of severe mental illness in your family and we will assess the appropriateness of an Ayahuasca retreat for you on an individual basis.
These drugs and medications are potentially dangerous with MAOIs:
- Other MAOIs
- SSRI’s (any selective serotonin reuptake inhibitor)
- Antihypertensives (high blood pressure medicine)
- Appetite suppressants (diet pills)
- Medicine for asthma, bronchitis, or other breathing problems; antihistamines, medicines for colds, sinus problems, hay fever, or allergies (Actifed DM, Benadryl, Benylin, Chlor-Trimeton, Compoz. These include Bromarest-DM or -DX, Dimetane-DX cough syrup, Dristan Cold & Flu, Phenergan with Dextromethorphan, Robitussin-DM, Vicks formula 44-D several Tylenol cold, cough, and flu preparations, and many others — any drug with DM or Tuss in its name.)
- CNS (central nervous system) depressants
Illegal or recreational drugs that are very dangerous to combine with MAOIs:
- Amphetamines (meth-, dex-, amphetamine)
- MDMA (Ecstasy)
- Dextromethorphan (DXM)
Illegal or recreational drugs that may be dangerous to combine with MAOIs:
- Mescaline (any phenethylamine)
Other psychoactives that should not be combined with MAOIs:
Due to a very limited number of of past guests who have not adhered to dietary restrictions before and / or after leaving a workshop, we need to emphasize that maintaining the Ayahuasca diet is an absolutely essential factor in the healing process. The three most fundamental restrictions before and after a workshop are street drugs (cocaine, ecstasy, heroin, etc), sexual activity and pork. If a guest decides to not adhere to this critical advice after leaving our Ayahuasca Retreat, we cannot be held liable for the consequences (which can be severe psychological and energetic damage).
For the safety and well-being of all guests, if we suspect that street drugs have been taken or if it is clear that alcohol has been consumed immediately prior to arrival at El Camino Sagrado, we reserve the right to refuse admission to a workshop.
Note about interaction with cannabis:
Smoking cannabis before the ayahuasca session may possibly stupefy and darken the overall experience acting as a blockage for the visionary plant to manifest in the fullest way. Given the general amplified sensitivity of all participants in an ayahuasca session, cannabis can sometimes negatively affect not just the person who used it, but also potentially other participants’ experiences as well as the overall energy level of the medicine circle. We recommend not smoking cannabis for two weeks prior to the retreat.

Additional Information and Contraindications
Using stimulants with MAOIs is particularly dangerous and can be potentially fatal. Using cocaine, amphetamines, or MDMA (ecstasy) with MAOIs may cause a severe increase in blood pressure, increasing the chances for stroke and cerebral hemorrhage and making it possible to overdose on a relatively small amount of cocaine. (A fatality has been recorded involving combining peganum harmala and cocaine. Fatalities resulting from combining amphetamines with pharmaceutical MAOIs have been recorded in the medical literature.)
Using other serotonin agonists or precursors with an MAOI can lead to serotonin syndrome. The main symptom of serotonin symptom may be a severe and long-lasting headache (the same symptom as MAOI tryptamine interaction) and/or fever (as high as 40 °C / 104 °F or more) Other symptoms of serotonin syndrome may include rapid heartbeat, shivering, sweating, dilated pupils, intermittent tremor or twitching, overactive or over-responsive reflexes, hyperactive bowel sounds, or high blood pressure. Severe serotonin syndrome may lead to shock, agitated delirium, muscular rigidity and high muscular tension, renal failure, or seizures, and can be life-threatening.
Using tricyclic antidepressants within two weeks of taking MAOIs may cause serious side effects including sudden fever, extremely high blood pressure, convulsions, and death.
Using Fluoxetine (Prozac) within five weeks of taking MAOIs may cause high fever, rigidity, high blood pressure, mental changes, confusion, and hypomania.
Using Benzedrine, Benzphetamine, Desipramine, Desoxyn, Dexedrine, Dopamine, Ephedrine (contained in Marax, Quadrinal, and other asthma drugs), Epinephrine, Guanadrel, Guanethidine, Hydralazine, Isoproterenol, L-dopa, Metaraminol, Methyldopa, Mirtazamine, Norepinephrine Oxymetazoline, Phendimetrazine, Phentermine, Phenylephrine, Phenylpropanolamine, Pseudoephedrine, Ritalin, or Venlafaxine with MAOIs may cause a hypertensive crisis (severe spike in blood pressure).
Using Adderall with MAOIs can result in high body temperature, seizure, and in some cases, coma.
Using Bupropion (Wellbutrin) within two weeks of taking MAOIs may cause serious side effects such as seizures.
Using Buspirone (Buspar) with MAOIs may cause high blood pressure and increased sedative effects.
Using Carbamazepine (Tegretol) with MAOIs may result in fever and may increase seizures, especially in epileptics.
Using Clomipramine with MAOIs may cause high fever (hyperpyrexic crisis) and seizures.
Using CNS depressants with MAOIs may increase the depressant effects.
Using Desipramine (Norpramin, Pertofrane) with MAOIs may result in hypertensive crisis.
Using Dextromethorphan with MAOIs may cause excitement, high blood pressure, and fever, or brief episodes of psychosis.
Using Fenfluramine with MAOIs may result in fever (hyperpyrexic crisis).
Using Kava with MAOIs may result in hypotensive crisis (severe blood pressure drop).
Using Lithium with MAOIs may cause fever and serotonin syndrome.
Using Meperidine (Demerol) with pharmaceutical MAOIs has resulted in deaths from a single dose.
Using Metaproterenol or other beta-adrenergic bronchodilators with MAOIs may cause blood pressure elevation and rapid heartbeat.
Using Mirtazapine (Remeron) with MAOIs may result in hypertensive crisis.
Using Nefazodone (Serzone) may result in high fever.
Using Temaril with MAOIs may increase chance of side effects.
Using Terfenadine with MAOIs may cause an increase in MAOI blood levels.
Using Theophylline with MAOIs may cause rapid heartbeat and anxiety.
Using Trazodone (Desyrel) with MAOIs may result in high fever.
Using Tryptophan or L-tryptophan with MAOIs may cause disorientation, confusion, amnesia, delirium agitation, memory impairment, hypomanic signs, or shivering.
Using Venlafaxine (Effexor) with MAOIs may result in hypertensive crisis.
Using Ziprasidone (Geodon) with MAOIs may cause serotonin syndrome.
Using alcohol with MAOIs may cause side effects like angina (chest pain) or headaches. The headache may mask or be mistaken for hypertensive crisis caused by MAOI interaction. MAOIs can also increase the sedative effect of alcohol.
Using opiates with MAOIs carries a risk of respiratory depression.
Using diuretics with MAOIs may cause a greater drop in blood pressure than normal and increase in MAOI blood levels.
Using anesthetics with MAOIs may potentiate the anesthetic effect.
Using sleeping pills, tranquillizers (major or minor), or barbiturates with MAOIs may increase the sedative effect.
