Understanding ibogaine's effect on QT interval: what the research says

There's a lot of fear around ibogaine and cardiac safety, and while that caution is warranted, I want to share what the current research actually shows. **Key findings from recent studies (2024-2026):** 1. **QT prolongation is real but manageable** — Ibogaine typically prolongs the QT interval by 50-100ms. This returns to baseline within 24-72 hours in most patients. 2. **Pre-screening eliminates most risk** — A comprehensive cardiac workup (12-lead EKG, echocardiogram for high-risk patients) identifies the vast majority of contraindicated individuals. 3. **Noribogaine is the main concern** — The metabolite noribogaine has a longer half-life and causes more sustained QT prolongation than ibogaine itself. CYP2D6 poor metabolizers are at higher risk. 4. **Beond Health data** — Their published data on 3,000+ treatments shows zero cardiac fatalities with proper medical screening and monitoring. 5. **Drug interactions matter most** — Most reported cardiac events involved concurrent use of contraindicated medications (methadone, SSRIs, etc.). **Bottom line:** Ibogaine does carry cardiac risk. But with proper medical screening, continuous cardiac monitoring during treatment, and appropriate patient selection, the risk is manageable. The key is choosing a provider that takes these precautions seriously. I'm happy to discuss specific studies if anyone wants references.
