A single dose appears to interrupt drug withdrawal and craving and ease depression, anxiety, and trauma symptoms, with large, rapid reported effects. The evidence remains weak and mostly uncontrolled, and some carries financial conflicts. Ibogaine can dangerously disturb the heart's rhythm, cause coordination problems and seizures, and is illegal in the US. (Full Review)
| Marker | Target | Why |
|---|---|---|
| QTc interval (ECG) | < 440 ms (men), < 450 ms (women) | Detects the heart-rhythm delay that drives ibogaine's fatal arrhythmia risk |
| Serum potassium | 4.0–4.5 mmol/L | Low potassium worsens QTc prolongation and arrhythmia risk |
| Serum magnesium | High-normal (≥ 0.9 mmol/L) | Magnesium stabilizes cardiac rhythm and protects against QTc prolongation |
| Liver enzymes (ALT/AST) | ALT/AST < 25 U/L | Ibogaine is metabolized hepatically; impairment raises exposure and toxicity |
| CYP2D6 genotype | Normal (extensive) metabolizer | Poor metabolizers clear ibogaine slowly, raising toxic exposure |
Cadence: Baseline screening before treatment; continuous ECG and vital-sign monitoring during dosing and for at least 24 hours after, with electrolyte rechecks as needed; clinical and psychological follow-up at 1 week, 1 month, then periodically.
