Preparation is where the safety is created.

The medical phase begins with a comprehensive history and physical examination. Particular attention goes to the cardiovascular system because ibogaine's blockade of hERG potassium channels can prolong the QT interval and predispose to arrhythmias. A baseline 12-lead ECG is therefore essential, and any QTc prolongation, conduction abnormality, or suggestive symptom requires specialist review.

Laboratory testing focuses on electrolytes, especially potassium and magnesium, because even mild depletion amplifies cardiac risk. Liver and renal function, full blood count, and pregnancy testing when relevant round out the initial panel. Abnormal results are corrected and repeated before any administration is scheduled.

Hydration and nutrition

Dehydration, poor oral intake, vomiting, diarrhoea and prolonged substance use all disturb electrolytes. Preparation includes restoring hydration and nutritional status before arrival, not scrambling to correct them on the day of treatment.

Ibogaine is metabolised in part by CYP2D6 and can interact with drugs that prolong the QT interval. Relevant categories include certain antidepressants, antipsychotics, cardiac medications, antibiotics, antiemetics, and some over-the-counter or herbal products. Methadone and buprenorphine also require careful handling.

Because of these interactions, a qualified clinician must review every medication and supplement. Some may need to be tapered or switched; others may make ibogaine inadvisable. The decision is never a do-it-yourself adjustment. Stopping medication abruptly can cause withdrawal, relapse, or cardiac destabilisation.

Psychological preparation is not positive thinking. It is a realistic review of what the experience may involve: its long duration, the possibility of difficult content, the physical recovery period, and the fact that the session itself does not automatically produce lasting change.

Useful preparation also clarifies intentions, identifies current stressors, reviews past trauma responses, and arranges support for the return home. People who enter with a clear plan for sleep, nutrition, relationships, and ongoing therapy generally integrate better than those who expect the medicine to do the work alone.

Informed consent should be specific, documented, and reviewed in conversation rather than signed at a desk. It must cover the investigational status of ibogaine, cardiac and neurological risks, potential drug interactions, the possibility of psychological distress, and the limits of the evidence. It should also confirm that the person can withdraw at any stage.

Logistics include travel plans, length of stay, who will know the person is away, how prescribed medications will be managed, and what support exists for the recovery period. During that period, fatigue, unsteadiness and disrupted sleep are common, so practical arrangements matter.

Integration planning begins before the experience, not after it. The preparation process should identify continuing therapeutic support, medical follow-up, peer or community resources, and any coordination with existing clinicians. The observational literature suggests that durable change depends more on what happens in the weeks and months after ibogaine than on the acute session itself.
