Tell your doctor you are considering ibogaine ceremony. Request an EKG and a full blood panel — liver function, kidney function, complete blood count. List every medication you currently take, including supplements and anything prescribed by other physicians. Most doctors are unfamiliar with ibogaine specifically; that is not a reason to withhold the information. Your ibogaine provider will require this documentation before confirming candidacy. Your own doctor needs it to support the process — particularly if a supervised medication taper is required before ceremony can proceed.
Every candidate for ibogaine ceremony requires: EKG and cardiovascular assessment, blood panel (liver enzymes, kidney function, CBC), full medication review, medical history, and psychiatric history. In Canada, ibogaine is not listed under the Controlled Drugs and Substances Act — it is not prohibited. The medical screening is not about legality. It is about whether ibogaine is safe for your specific cardiovascular and metabolic situation. Ceremony costs $2,000–$5,000 CAD at Transcend in Vancouver, BC. Every application receives a personal response within 2–3 business days.

What ibogaine providers require before ceremony
A legitimate ibogaine provider will not confirm a ceremony date without reviewing medical records. Not because they are being bureaucratic — because ibogaine has real cardiac contraindications, and the only way to identify them before ceremony rather than during it is a pre-ceremony EKG. The screening is not a formality. It is how providers establish whether ceremony is safe for you specifically.
At Transcend in Vancouver, BC, the required pre-ceremony documentation includes:
- EKG with cardiovascular assessment. Ibogaine prolongs the QT interval throughout the 12–24 hour active experience. Pre-existing QT prolongation on an unchecked EKG is a serious arrhythmia risk. The EKG identifies this before ceremony. A 12-lead EKG can be obtained at any cardiology clinic or most walk-in centres. The provider reviews the results before any date is confirmed.
- Blood panel: liver enzymes, kidney function, complete blood count.Ibogaine is metabolised hepatically via the CYP2D6 enzyme. Compromised liver function — common in people with a history of alcohol use disorder — extends ibogaine's active duration unpredictably and increases cardiac exposure. Severe liver or kidney disease is an absolute contraindication. Elevated-but-improving enzyme levels require reassessment, not a permanent no.
- Complete medication list. Every prescription, every supplement, every psychiatric medication — including anything taken intermittently. SSRIs and SNRIs are absolute contraindications not because providers prefer you not take them, but because the combination with ibogaine creates conditions for serotonin syndrome, which can be fatal. Methadone requires a specific transition protocol. Lithium is an absolute contraindication with no protocol that makes it safe.
- Full medical history. Cardiac conditions, recent surgeries, significant illnesses. A history of myocardial infarction, certain arrhythmias, or significant hypertensive disease requires additional cardiovascular assessment before candidacy can be established.
- Psychiatric history. Current diagnosis, past hospitalisations, family history of psychosis or schizophrenia-spectrum disorder. Active psychosis and schizophrenia-spectrum conditions are absolute contraindications. A first-degree family member with schizophrenia is a contraindication. Current acute psychiatric instability is a disqualifier, not a reason to rush to ceremony. The experience amplifies what is present. It does not stabilise it.
Any ibogaine provider who does not require an EKG before ceremony is not operating safely. Full stop. The cardiac risk from ibogaine in someone with unidentified QT prolongation is not theoretical — ibogaine-related fatalities have occurred in this exact scenario. Providers who skip cardiac screening are not cutting costs on something incidental. They are removing the mechanism that identifies the people who cannot survive the ceremony.
How to talk to your own doctor
Most general practitioners in Canada and the United States have not been asked about ibogaine. Your GP may have no position on it. They may be unfamiliar with its pharmacology. They may be sceptical. None of this excuses withholding the information.
The conversation has a specific purpose: to get the documentation your ibogaine provider needs. An EKG, a blood panel with the markers your provider requests, a review of your current medications, and any relevant cardiac or psychiatric history. You are not asking for permission. You are gathering the information that will determine whether this is safe for you specifically.
Tell your doctor exactly what you are considering. Something like: “I am researching ibogaine ceremony for [depression / opioid dependence / PTSD] and I need an EKG and blood panel as part of the intake screening for a programme in Vancouver, BC.” This is accurate. It is also how you get the referral instead of a vague conversation about whether this is advisable.
In Canada, ibogaine is not listed under the Controlled Drugs and Substances Act. It is not prohibited. Your doctor does not need to worry about being implicated in anything by ordering routine diagnostic tests. The EKG and bloodwork are standard clinical tools. The context of ibogaine screening does not change what they are.
If your GP is unreceptive, a walk-in clinic can order an EKG. Private blood panel services operate in most Canadian cities. The screening does not require your GP's endorsement — it requires the test results.
Your GP also needs to know if you are on any medication that requires tapering before ceremony. The SSRI taper must be supervised by the prescribing physician. This is not something to attempt alone. Stopping SSRIs abruptly carries its own risks, and the taper timeline must be long enough to ensure full clearance. Fluoxetine has a significantly longer half-life than other SSRIs — in some cases requiring 4–6 weeks of clearance after the final dose. Your prescribing physician sets the taper schedule. Your ibogaine provider confirms the clearance window is adequate before a ceremony date is confirmed.
Medications — what must be disclosed and what disqualifies
Medication disclosure is the most consequential part of the intake conversation. The interaction profile for ibogaine is broad. Several common medications are absolute contraindications. Others require preparation — supervised tapering or transition protocols — before ceremony can proceed.
Absolute contraindications — ceremony cannot proceed without full clearance
SSRIs and SNRIs. Selective serotonin reuptake inhibitors (fluoxetine, sertraline, escitalopram, and others) and serotonin-norepinephrine reuptake inhibitors (venlafaxine, duloxetine) must be fully cleared before ibogaine ceremony. The mechanism of concern is serotonin syndrome — an acute, potentially fatal condition. SSRIs are the most common medications in the population seeking ibogaine treatment, because they are the first-line treatment for depression, anxiety, and PTSD — the exact conditions ibogaine is most often sought for. This is the most frequent reason applications require preparation rather than a direct yes. A supervised taper is required, not optional.
Lithium. Lithium is an absolute contraindication with no exception and no workaround protocol. This is not a taper-and-wait situation in the way SSRIs are — lithium use is a permanent disqualifier until the medication has been discontinued under physician supervision for an appropriate washout period. Any decision about changing lithium dosing must involve both the ibogaine provider and the prescribing psychiatrist.
Methadone. Methadone maintenance therapy requires a specific transition protocol before ibogaine is safe to administer. Methadone cannot simply be tapered — the transition to a shorter-acting opioid must be completed first under physician supervision. This is not a fast process. For people on methadone who want ibogaine treatment, the preparation timeline is typically longer than for any other medication situation — but ibogaine treatment is accessible through the correct protocol.
MAOIs and ayahuasca.Monoamine oxidase inhibitors — including the beta-carbolines present in ayahuasca — are an absolute contraindication for ibogaine. The combination creates conditions for serotonin syndrome and dramatically amplifies ibogaine's effects. If you have used ayahuasca within the past month, tell your ibogaine provider directly. A minimum washout period applies; the specific window depends on the compound and duration of use.
Most antipsychotics. Current antipsychotic use is contraindicated in most cases. Any current antipsychotic use — typical or atypical — requires specific discussion with the ibogaine provider, and in most cases rules out candidacy.
Situations requiring preparation rather than an automatic no
Benzodiazepines post-detox. For candidates who have recently completed alcohol or sedative withdrawal treatment, benzodiazepines must be fully cleared before ibogaine ceremony. The clearance timeline depends on the specific drug and duration of use. Long-acting benzodiazepines (diazepam, clonazepam) take longer than short-acting ones. Do not misrepresent the date of your last dose.
QT-prolonging medications. Many medications beyond psychiatric drugs affect the QT interval — certain antibiotics, antifungals, antihistamines, and cardiac drugs. The CredibleMeds QTDrugs List categorises medications by their QT risk. Your ibogaine provider will review your medication list against it. The EKG establishes your baseline; the medication review establishes whether any current drugs are adding to that risk.
The cardiac mechanism is well-documented: ibogaine blocks hERG potassium channels, prolonging the QT interval throughout the active experience. In someone with a pre-existing abnormality — whether from genetics, prior cardiac disease, or QT-prolonging medications — the additional prolongation ibogaine introduces can push the interval into arrhythmic territory. The EKG is the only way to rule this out in advance. Providers who skip it are not simplifying the process. They are skipping the only safeguard that matters for the most serious risk.

Who this is not right for
The following are absolute disqualifiers. They apply regardless of motivation, clinical history, or willingness to proceed.
- QT prolongation or significant cardiac arrhythmia on EKG. Identified during pre-ceremony screening. Cannot be determined without the test. If the EKG reveals QT prolongation, ceremony cannot proceed — the risk of ibogaine-induced ventricular arrhythmia is too high.
- Recent myocardial infarction or unstable cardiovascular disease. A recent MI or unstable cardiac condition disqualifies. The specific timeframe and clinical picture require physician assessment.
- Severe liver or kidney disease.Impaired hepatic function extends ibogaine's active duration unpredictably and increases cardiac exposure. Severe impairment is a hard contraindication. Elevated-but-improving enzyme levels require reassessment.
- Active psychosis or schizophrenia-spectrum disorder. Cannot be administered safely. The experience does not stabilise acute psychotic symptoms — it amplifies them. A first-degree family member with schizophrenia is a contraindication in most screening protocols.
- Current SSRIs, SNRIs, lithium, methadone, or most antipsychotics without completed preparation. The medication cannot simply be omitted the day before ceremony. The washout periods and transition protocols are specific and take weeks.
- Pregnancy. No ceremony at any provider, at any dose, during pregnancy.
- Acute psychiatric instability at the time of application. Active suicidality, recent psychiatric hospitalisation, or current acute self-harm requires different support before ceremony is appropriate. The medicine is not a stabilising intervention. It confronts what is present.
Some of these disqualifiers are permanent. Others require preparation time rather than a definitive no. The complete ibogaine contraindications guide explains which is which and what each situation requires.
What the screening conversation looks like
The intake conversation with an ibogaine provider is not a sales call. It is a medical assessment. The provider is trying to establish whether ceremony is safe for you specifically — not whether you want it, not whether your case is compelling, not whether you have read the Stanford study. Whether it is safe.
The conditions ibogaine addresses most effectively — opioid dependence, treatment-resistant depression, PTSD — are also the conditions most commonly treated with the medications that are absolute contraindications for ibogaine. A person who has been on SSRIs for years and is in real distress is exactly the person who needs to know their taper timeline before a ceremony date can be discussed. That is not a bureaucratic hurdle. It is the work.
Not everyone who applies is an appropriate candidate. Some have cardiac findings that make ibogaine genuinely dangerous. Some are on medications that cannot be tapered in any reasonable timeframe. Some are in states of acute instability that require a different kind of support first. The conversation that ends in “this is not the right path for you at this moment” is one of the most important things a legitimate provider does. People in crisis who have found a thread of hope do not receive that no easily. Saying it clearly — without softening — is an act of care, not rejection.
At Transcend, every application receives a personal response within 2–3 business days. The people who receive a no receive the same quality of response as the people who receive a yes. If the situation is “not yet,” that is also explained directly. The guide to ibogaine therapy in Canada covers what the full intake and preparation sequence involves.
The 2023 Stanford study published in Nature Medicine documented 88% reductions in PTSD symptoms, 87% reductions in depression symptoms, and 81% reductions in anxiety symptoms at one month in 30 special operations veterans. That population had exhausted conventional approaches. But it was also a screened population. The results at one month were not independent of the assessment that came before ceremony.
Is this right for you?
If you are researching ibogaine treatment, the next step is not a ceremony — it is a screening conversation. Before that conversation, get an EKG and review your current medications against the contraindication list. Both can be obtained before you contact a provider. Both shorten the intake timeline.
If you are on SSRIs, SNRIs, methadone, lithium, or an antipsychotic, that does not mean ibogaine is permanently unavailable to you. It means the timeline requires planning. Do not attempt to stop any psychiatric medication without physician supervision in order to accelerate access to ceremony. That is not preparation — it is a separate risk that serves no one.
If you have a cardiac history or have never had an EKG, get it first. It will either confirm that ceremony is a possibility or identify a contraindication before either party has invested further in the process.

Frequently Asked Questions
Do I need to tell my doctor I am planning an ibogaine ceremony?
Yes. Your doctor needs to know to provide the required documentation — EKG, blood panel — and to supervise any medication taper before ceremony. They may be unfamiliar with ibogaine. That is not a reason to withhold the information. Tell them specifically what you are considering and what tests you need. The documentation can be obtained without your GP's endorsement of the decision — it requires their clinical services, not their approval.
What should I tell my ibogaine provider during intake?
Everything. Every medication — including supplements and anything taken intermittently. Any cardiac history, including palpitations or anything identified on a previous EKG. Any psychiatric history, including hospitalisations and family history of psychosis. Any current substance use, including the last date of use. The intake conversation is where safety is established. Incomplete disclosure does not protect you from a contraindication — it means the contraindication is not identified before ceremony.
Can I do ibogaine if I am on antidepressants?
Not without a completed physician-supervised taper first. SSRIs and SNRIs are absolute contraindications — the risk is serotonin syndrome, which can be fatal. A supervised taper is required. Fluoxetine has a significantly longer half-life than other SSRIs and may require 4–6 weeks of clearance after the final dose. Do not stop any psychiatric medication on your own in order to access ceremony faster. The taper must be supervised and the clearance window confirmed with the ibogaine provider before any ceremony date is set.
What is QT prolongation and why does it matter for ibogaine?
QT prolongation is an extension of the electrical recovery phase of the heartbeat, visible on an EKG as a lengthened QT interval. Ibogaine further prolongs this interval throughout the active experience via hERG channel blockade. In someone with pre-existing QT prolongation, ibogaine can push the interval into the range associated with ventricular arrhythmia. The EKG identifies this before ceremony. It is why no legitimate provider confirms a ceremony date without reviewing one.
Can I do ibogaine if I am on methadone?
Not without completing a specific transition protocol first. The protocol requires transitioning from methadone to a shorter-acting opioid under physician supervision — a process that takes weeks and must be coordinated between the patient, the prescribing physician, and the ibogaine provider. The preparation timeline for someone on methadone maintenance is longer than for most other medication situations. But ibogaine treatment is accessible for this population through the correct protocol.
How long before ibogaine do I need to stop SSRIs?
The taper timeline depends on which SSRI and the duration of use. Most SSRIs require a supervised taper followed by a clearance period of at least 2–4 weeks after the final dose. Fluoxetine is the exception — its significantly longer half-life means clearance may require 4–6 weeks or more after the final dose. The prescribing physician sets the taper. The ibogaine provider confirms the clearance window is adequate. No ceremony date is confirmed before both conditions are met.
Who should not apply for ibogaine ceremony?
Anyone with QT prolongation or significant cardiac arrhythmia; severe liver or kidney disease; active psychosis or schizophrenia-spectrum disorder; a first-degree family member with schizophrenia; or acute psychiatric instability should not apply until those conditions are assessed and addressed. Pregnancy is an absolute disqualifier. Someone primarily seeking a shortcut — rather than prepared for a physically and psychologically demanding process — is also not an appropriate candidate. The medicine tends to show people what they have been avoiding, not what they came to find.
