Before arrival
Screening is not paperwork.
A credible safety conversation starts before travel. Ibogaine has recognized cardiac risk, including effects on electrical conduction that can lengthen the QT interval and raise concern for dangerous rhythm disturbances. The U.S. Food and Drug Administration has described serious safety concerns around ibogaine, including cardiac arrhythmias and deaths reported in association with its use.
Pre-arrival review should therefore be specific: medical history, prior fainting or arrhythmia, cardiac disease, current prescriptions and non-prescription substances, and a recent ECG interpreted by an appropriately qualified clinician. Electrolytes and other relevant laboratory findings may matter because potassium or magnesium abnormalities can add to rhythm risk. A careful medication review is central, particularly where drugs affect cardiac conduction, seizure threshold, metabolism, or serotonin activity.
Psychiatric risk also requires plain discussion. Acute distress, confusion, mania, psychosis, suicidality, and trauma-related destabilization are not problems that can be screened away with a checkbox. Substance use may need stabilization before travel as well, especially where alcohol, benzodiazepines, opioids, stimulants, or other substances create withdrawal, intoxication, or interaction concerns. The broader care around ibogaine in Mexico should make room for this preparation instead of treating it as an obstacle to a scheduled date.
