Ibogaine and Fluoxetine
Also known as: Prozac, Sarafem
Serotonin syndrome risk. Fluoxetine has extremely long half-life (4-6 days; norfluoxetine 4-16 days). Noribogaine is a potent serotonin reuptake inhibitor.
Severity
Contraindicated
Mechanism
Serotonergic activity (serotonin syndrome)
Protocol Status
Pre-arrival washout (under your prescribing physician)
Restart Delay
14 days
What "Contraindicated" Means
Absolute prohibition without an enforced washout. Treatment cannot proceed safely until the medication has been cleared from the body for the protocol's required interval.
Clinical Action
What our medical team does for patients on Fluoxetine.
MUST discontinue minimum 5 weeks (35 days) before treatment due to active metabolite.
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
35 days minimum (long half-life — extended washout).
Post-Treatment Restart
Wait at least 14 days post-treatment before restarting.
The Pharmacology
How Fluoxetine interacts with ibogaine: serotonergic activity (serotonin syndrome).
Noribogaine is a potent serotonin reuptake inhibitor. Combining it with another drug that raises synaptic serotonin (SSRIs, SNRIs, MAOIs, triptans, tramadol, MDMA, St John's Wort) can trigger serotonin syndrome — autonomic instability, hyperthermia, neuromuscular hyperactivity, and altered mental state. This is a leading cause of preventable harm in psychedelic medicine and the reason serotonergic medications carry the longest washout windows.

Common Questions
Fluoxetine and ibogaine treatment.
Can I take ibogaine if I am on Fluoxetine?
Contraindicated. Serotonin syndrome risk. Fluoxetine has extremely long half-life (4-6 days; norfluoxetine 4-16 days). Noribogaine is a potent serotonin reuptake inhibitor. MUST discontinue minimum 5 weeks (35 days) before treatment due to active metabolite.
How long do I need to be off Fluoxetine 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. 35 days minimum (long half-life — extended washout). Wait at least 14 days post-treatment before restarting.

This is a leading cause of preventable harm in psychedelic medicine and the reason serotonergic medications carry the longest washout windows.
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 Fluoxetine — contact us for an individual review.
