Ibogaine Drug Interaction Checker

Ibogaine and its active metabolite noribogaine are potent serotonin reuptake inhibitors. Stacking a full SSRI dose with the HCl flood dose creates serotonin syndrome risk — agitation, hyperthermia, autonomic instability, seizures. At MindScape, however, the SSRI taper is performed onsite, not at home: patients arrive on their current prescribed dose and are stepped down under continuous physician supervision and telemetry, supported by twice-daily ibogaine TA (total alkaloid) booster doses that bridge serotonergic tone during washout. The HCl flood dose is administered only after the SSRI has been titrated to the protocol-defined safe threshold. The pharmacology that drives the timing differs by drug — fluoxetine (Prozac) has a 4-6 day half-life with a 4-16 day metabolite half-life, so its onsite taper schedule is materially longer than for shorter-half-life SSRIs.

Methadone is a major-risk medication that requires careful tapering rather than abrupt discontinuation. We taper patients to 30 mg/day or lower over weeks, then transition to a short-acting opioid where appropriate, then time the last opioid dose 36-48 hours before ibogaine dosing so the patient is in objective withdrawal (COWS ≥ 8). Methadone also prolongs QTc, so a baseline EKG and electrolyte panel are mandatory.

MAOIs (phenelzine, tranylcypromine, isocarboxazid, selegiline at non-selective doses) combined with ibogaine's serotonergic activity create a life-threatening risk of serotonin syndrome and hypertensive crisis. This is non-negotiable: a minimum 14-day washout is required before any ibogaine session, regardless of clinical urgency.

Long-term benzodiazepine users require slow, supervised tapers — abrupt discontinuation can cause seizures, and home-based tapers are exactly the scenario that produces withdrawal seizures. At MindScape you do not taper at home: you arrive on your currently prescribed benzodiazepine and the entire taper is conducted onsite under 24/7 physician supervision and telemetry. The protocol typically begins with a crossover to diazepam (long half-life, smoother withdrawal curve) followed by graduated dose reduction supported by twice-daily ibogaine TA booster doses, which modulate GABA-A stability during the taper. The HCl flood dose is administered only after the benzodiazepine has been titrated to the protocol-defined safe threshold; chronic benzodiazepine pharmacology is never stacked at full dose with the flood-dose session.

Our database covers 96 of the most common interacting medications. If your prescription is not listed, contact our medical team for a manual review — washout windows for less-common drugs depend on half-life, CYP2D6 involvement, QTc effect, and serotonergic activity, all of which require clinician judgment.

Yes — we include St. John's Wort (potent CYP3A4 inducer + serotonergic), 5-HTP and tryptophan (serotonergic), grapefruit juice (CYP3A4 inhibitor), kava (hepatotoxic), and other clinically significant supplements. Always disclose every supplement to our medical team during screening.

Amiodarone has an unusually long half-life (40-55 days) and dramatically prolongs QTc. The combined cardiac risk with ibogaine is potentially fatal. Because amiodarone cannot be safely washed out within any reasonable timeline, patients on amiodarone are typically ineligible for ibogaine treatment until alternative antiarrhythmic management is established with cardiology.

Yes. Ibogaine is metabolized primarily by CYP2D6. Strong CYP2D6 inhibitors (paroxetine, fluoxetine, bupropion, quinidine) increase ibogaine plasma exposure and prolong noribogaine action — increasing both efficacy and risk. Genotyping or phenotyping for CYP2D6 status, plus dose adjustment, is part of our pre-treatment workup whenever indicated.

Our /ibogaine-drug-interactions page is a comprehensive narrative reference covering categories, mechanisms, and clinical reasoning. This tool lets you search the same dataset by drug or brand name and see washout/restart windows at a glance. Use the reference page to understand the why; use this tool to look up a specific medication.
