Furosemide
Lasix, Frusemide
Ibogaine and Hydrocortisone
Also known as: Cortef, Solu-Cortef
Systemic corticosteroid with the highest mineralocorticoid activity per anti-inflammatory unit of the common steroids, so potassium wasting is proportionally greater. Often prescribed as physiologic replacement for adrenal insufficiency, where stopping it is dangerous.
Severity
Moderate caution
Mechanism
Electrolyte disturbance
Protocol Status
Continue as prescribed — cleared by a measured lab value, not a waiting period
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 Hydrocortisone.
Establish WHY it is prescribed. If it is adrenal replacement it must never be interrupted and may need a stress dose. Measure K+ and Mg2+ before dosing.
Where the Washout Happens
Continue as prescribed — cleared by a measured lab value, not a waiting period
This medication is not stopped for treatment, and should not be stopped on our initiative — the condition it treats usually outranks the interaction. What it changes is monitoring: serum potassium and magnesium are measured before the flood dose and corrected to target, and the dose is deferred until those numbers are right rather than until a number of days have passed. Any change to the prescription belongs to the prescribing physician.
Post-Treatment Restart
Restart at physician discretion once acute window closes.
The Pharmacology
How Hydrocortisone interacts with ibogaine: electrolyte disturbance.
QTc is exquisitely sensitive to potassium and magnesium. Diuretics, laxatives, and conditions that lower these electrolytes lengthen QT and add to ibogaine's hERG effect. Pre-treatment electrolyte panels and IV repletion are routine.

Common Questions
Hydrocortisone and ibogaine treatment.
Can I take ibogaine if I am on Hydrocortisone?
Moderate caution. Systemic corticosteroid with the highest mineralocorticoid activity per anti-inflammatory unit of the common steroids, so potassium wasting is proportionally greater. Often prescribed as physiologic replacement for adrenal insufficiency, where stopping it is dangerous. Establish WHY it is prescribed. If it is adrenal replacement it must never be interrupted and may need a stress dose. Measure K+ and Mg2+ before dosing.
How long do I need to be off Hydrocortisone before ibogaine treatment?
Continue as prescribed — cleared by a measured lab value, not a waiting period. This medication is not stopped for treatment, and should not be stopped on our initiative — the condition it treats usually outranks the interaction. What it changes is monitoring: serum potassium and magnesium are measured before the flood dose and corrected to target, and the dose is deferred until those numbers are right rather than until a number of days have passed.

What is the mechanism of the interaction?
Electrolyte disturbance. QTc is exquisitely sensitive to potassium and magnesium. Diuretics, laxatives, and conditions that lower these electrolytes lengthen QT and add to ibogaine's hERG effect. Pre-treatment electrolyte panels and IV repletion are routine.
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 Hydrocortisone — contact us for an individual review.
