Ibogaine and Morphine
Also known as: Ms Contin, Kadian
Ibogaine potentiates opioid effects. Must be in withdrawal.
Severity
Major risk
Mechanism
Opioid receptor potentiation
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 Morphine.
Last dose 12-24h before treatment. COWS score ≥8.
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
Last dose at least 24 hours before treatment.
Post-Treatment Restart
Restart at physician discretion once acute window closes.
The Pharmacology
How Morphine interacts with ibogaine: opioid receptor potentiation.
Ibogaine resets and re-sensitises the mu-opioid receptor. Any opioid still circulating during dosing is potentiated, raising the risk of respiratory depression. Patients must be in measurable, monitored withdrawal (typically COWS ≥ 8) before ibogaine is administered, and long-acting opioids like methadone or buprenorphine must be tapered or transitioned in advance.
Same Mechanism
Other medications that interact via opioid receptor potentiation.

Common Questions
Morphine and ibogaine treatment.
Can I take ibogaine if I am on Morphine?
Major risk. Ibogaine potentiates opioid effects. Must be in withdrawal. Last dose 12-24h before treatment. COWS score ≥8.
How long do I need to be off Morphine 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. Last dose at least 24 hours before treatment.
What is the mechanism of the interaction?
Opioid receptor potentiation. Ibogaine resets and re-sensitises the mu-opioid receptor. Any opioid still circulating during dosing is potentiated, raising the risk of respiratory depression. Patients must be in measurable, monitored withdrawal (typically COWS ≥ 8) before ibogaine is administered, and long-acting opioids like methadone or buprenorphine must be tapered or transitioned in advance.
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 Morphine — contact us for an individual review.
