Citalopram
Celexa
Ibogaine and Risperidone
Also known as: Risperdal
QTc prolongation + CYP2D6 substrate. Active metabolite paliperidone.
Severity
Major risk
Mechanism
QT-interval prolongation
Protocol Status
Pre-arrival washout (under your prescribing physician)
Restart Delay
Physician discretion
What "Major risk" Means
Serious clinical risk requiring physician-led tapering, washout, and monitoring. Treatment may proceed once the medication is appropriately cleared or transitioned.
Clinical Action
What our medical team does for patients on Risperidone.
Discontinue minimum 7 days before treatment.
Where the Washout Happens
Pre-arrival washout (under your prescribing physician)
Discontinuation is completed before arrival, under the patient's own prescribing physician, with the medication-specific washout interval observed before the flood dose.
Pre-Treatment Washout Window
7 days minimum before treatment.
Post-Treatment Restart
Restart at physician discretion once acute window closes.
The Pharmacology
How Risperidone interacts with ibogaine: qt-interval prolongation.
Ibogaine and noribogaine block the cardiac hERG (IKr) potassium channel, which lengthens ventricular repolarisation and the QTc interval on a 12-lead EKG. Adding a second QT-prolonging drug compounds the effect and raises the risk of torsades de pointes — a polymorphic ventricular tachycardia that can be fatal. Every patient receives a baseline EKG, electrolyte panel, and continuous cardiac monitoring; medications in this class must be washed out long enough to return QTc into a safe range.

Common Questions
Risperidone and ibogaine treatment.
Can I take ibogaine if I am on Risperidone?
Major risk. QTc prolongation + CYP2D6 substrate. Active metabolite paliperidone. Discontinue minimum 7 days before treatment.
How long do I need to be off Risperidone before ibogaine treatment?
Pre-arrival washout (under your prescribing physician). Discontinuation is completed before arrival, under the patient's own prescribing physician, with the medication-specific washout interval observed before the flood dose. 7 days minimum before treatment.
What is the mechanism of the interaction?
QT-interval prolongation. Ibogaine and noribogaine block the cardiac hERG (IKr) potassium channel, which lengthens ventricular repolarisation and the QTc interval on a 12-lead EKG. Adding a second QT-prolonging drug compounds the effect and raises the risk of torsades de pointes — a polymorphic ventricular tachycardia that can be fatal. Every patient receives a baseline EKG, electrolyte panel, and continuous cardiac monitoring; medications in this class must be washed out long enough to return QTc into a safe range.
Can I switch to a different medication so I can have ibogaine treatment?
In many cases yes. Our medical team works with your prescribing physician to taper or substitute medications safely before treatment. The right substitution depends on the underlying condition you are treating with Risperidone — contact us for an individual review.
