The Honest Answer

Iboga is a powerful medicine. For properly screened participants working with trained, experienced practitioners, it can be profoundly safe and transformative. For individuals with certain heart conditions, specific medications, or unstable psychiatric diagnoses, it carries serious risks — including, in poorly managed cases, fatalities.

The difference between a safe iboga experience and a dangerous one is almost entirely determined by the quality of medical screening and the experience of the practitioners.

This guide will tell you everything you need to know — honestly — about iboga safety.

The Primary Risk: Cardiac

Ibogaine, the primary alkaloid in iboga, prolongs the QTc interval — an electrical measurement of heart function that appears on an electrocardiogram (ECG). QTc prolongation can trigger potentially fatal cardiac arrhythmias, particularly Torsades de Pointes, a life-threatening irregular heartbeat.

This risk is well documented. An analysis of ibogaine-related deaths found that the majority involved one or more of the following:

• Pre-existing cardiac conditions, especially long QT or arrhythmia
• Concurrent use of opioids or other drugs around the time of dosing
• Contraindicated, QT-prolonging medications
• Inadequate or absent medical screening
• Unsupervised or self-administered use, often at home

When these factors are properly screened and eliminated, the cardiac risk drops dramatically. The 2024 Stanford study of 30 veterans found zero serious cardiac adverse events, because participants underwent rigorous pre-screening including a specific magnesium protocol that further protects against QTc prolongation.

Who Should NOT Take Iboga: Complete Contraindications

Absolute Contraindications (Do Not Proceed)

• Known long QT syndrome or a prolonged QTc on ECG
• Heart failure, previous heart attack, or structural heart disease
• History of cardiac arrhythmia
• Severe liver disease (iboga is metabolised by the liver)
• Severe kidney disease
• Active psychosis or schizophrenia
• Pregnancy or breastfeeding

Medications That Require Taper or Washout Before Iboga

The following medications must be safely reduced or discontinued under medical supervision before iboga is safe. Never stop any prescription medication abruptly without guidance from your prescribing doctor.

• Opioids — methadone in particular, because its long half-life requires switching to a shorter-acting opioid and a washout period
• Benzodiazepines
• SSRIs and SNRIs
• MAOIs
• Other QT-prolonging drugs (some antipsychotics, antiarrhythmics and antibiotics)
• Stimulants

Conditions Requiring Extra Caution and Medical Evaluation

• Controlled high blood pressure
• Diabetes
• History of seizures
• Stable, well-managed bipolar disorder
• Electrolyte imbalances (low potassium or magnesium)
• Eating disorders or very low body weight

What Proper Medical Screening Looks Like

A responsible iboga retreat or clinic will require the following before accepting any participant:

Mandatory Tests

• A 12-lead ECG to measure the QTc interval
• A comprehensive blood panel: electrolytes (potassium, magnesium), liver function (LFTs) and kidney function
• A full review of all medications and supplements
• Cardiac and psychiatric history
• Cardiology clearance for any borderline result

What Bwiti House's Screening Protocol Includes

At Bwiti House, no participant is accepted without complete medical clearance. Our protocol includes:

• A detailed pre-arrival medical questionnaire and history
• A required ECG and blood work (EKG and liver-function tests) before acceptance
• Medication review with supervised taper guidance where needed
• A magnesium and electrolyte optimisation protocol to protect the heart
• Continuous monitoring by trained Bwiti providers, with medical support, throughout the ceremony
• Individualised dosing decided only after medical clearance
• Aftercare and integration support

This process is not a formality. We decline participants whose screening results indicate unacceptable risk — because the safety of every person in our care is non-negotiable.

The 35-Year Safety Record

Bwiti House has been conducting iboga ceremonies with Western participants since 1990, making it one of the longest-running iboga retreat operations in the world. This 35-year track record, with thousands of initiations completed under Moughenda Mikala's guidance, represents a sustained safety record built on rigorous screening and authentic traditional practice.

The Bwiti tradition itself has practised with iboga for thousands of years. The tradition's accumulated knowledge about iboga preparation, dosing, ceremony structure, and participant monitoring is not incidental to safety, it is foundational to it.

Recognising an Unsafe Retreat

Red flags that suggest a retreat is not operating safely:

• No ECG or blood work required before booking
• No questions about your medications or medical history
• Claims that iboga is "100% safe" or "natural, so there's no risk"
• No medical personnel or emergency plan on site
• Group dosing with no individual screening
• Pressure to pay in full or book quickly with no assessment
• No aftercare or integration support

Frequently Asked Questions

Has anyone died from iboga?
Yes. There are documented cases of ibogaine-related deaths, the majority of which involve pre-existing cardiac conditions, concurrent drug use, or inadequate medical screening. When proper cardiac screening is performed and contraindicated medications are managed, the risk of serious adverse events is very low. Reputable centres have conducted thousands of sessions without serious cardiac events.

Is iboga safe for someone with a history of depression?
Depression itself is not a contraindication. The medications used to treat depression (particularly SSRIs and MAOIs) require careful management. Participants with depression who are not on contraindicated medications, or who have completed a safe medication taper, can typically participate safely.

Can I do iboga if I drink alcohol regularly?
Moderate social alcohol use is generally not a contraindication, but heavy alcohol use and alcohol use disorder require specific evaluation. Liver function is a key screening criterion — heavy drinkers often have elevated liver enzymes that need to be within safe range before iboga is appropriate.

What happens if something goes wrong during the ceremony?
Responsible retreat centres have emergency protocols and medical support on-site. Bwiti House operates with proximity to medical facilities and has trained staff who monitor participants throughout the ceremony. The continuous monitoring by the shaman and support team is one of the safety advantages of the traditional ceremonial setting over unsupervised use.

Is iboga safe for people over 50?
Age itself is not a contraindication. Cardiac health is the primary concern, and this is assessed via ECG regardless of age. Many participants in their 50s, 60s, and older have completed iboga ceremonies safely after proper medical clearance.
