Lithium
Lithobid, Eskalith
Ibogaine and Propranolol
Also known as: Inderal
CYP2D6 substrate + beta-blocker. Risk of severe bradycardia.
Severity
Moderate caution
Mechanism
Cardiac conduction (bradycardia / AV node)
Protocol Status
Pre-arrival washout (under your prescribing physician)
Restart Delay
Physician discretion
What "Moderate caution" Means
Use with caution. Often requires a brief hold, dose reduction, or enhanced monitoring rather than full discontinuation.
Clinical Action
What our medical team does for patients on Propranolol.
Hold on treatment day. Resume cautiously post-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
Hold on dosing day; physician-directed timing.
Post-Treatment Restart
Restart at physician discretion once acute window closes.
The Pharmacology
How Propranolol interacts with ibogaine: cardiac conduction (bradycardia / av node).
Ibogaine slows the sinus node and AV conduction. Beta-blockers, non-dihydropyridine calcium channel blockers, digoxin, and lithium can deepen bradycardia or generate higher-degree AV block. Heart-rate-slowing medications are typically held on dosing day with continuous telemetry monitoring.
Same Mechanism
Other medications that interact via cardiac conduction (bradycardia / av node).
Same Severity Tier
Other moderate caution medications (different mechanism).
Common Questions
Propranolol and ibogaine treatment.
Can I take ibogaine if I am on Propranolol?
Moderate caution. CYP2D6 substrate + beta-blocker. Risk of severe bradycardia. Hold on treatment day. Resume cautiously post-treatment.
How long do I need to be off Propranolol 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. Hold on dosing day; physician-directed timing.
What is the mechanism of the interaction?
Cardiac conduction (bradycardia / AV node). Ibogaine slows the sinus node and AV conduction. Beta-blockers, non-dihydropyridine calcium channel blockers, digoxin, and lithium can deepen bradycardia or generate higher-degree AV block. Heart-rate-slowing medications are typically held on dosing day with continuous telemetry monitoring.
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 Propranolol — contact us for an individual review.
