Iboga + Lamotrigine

Lamotrigine brand name: Lamictal.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Iboga and Lamotrigine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Iboga and Lamotrigine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lamotrigine and Iboga in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Iboga safety at a glance

Iboga overall Avoid Iboga can cause dangerous heart rhythm problems and has been linked to deaths.
Pregnancy Avoid Not enough safety information; the risks make it unsafe during pregnancy.
Breastfeeding Avoid No safety data; avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Lamotrigine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lamotrigine is filed under 5 classifications — including anticonvulsants, glucuronidated drugs, cns depressants. Iboga has documented interactions with 6 drug classes — the most serious being paroxetine (paxil) (major), anticholinergic drugs (moderate) and cholinergic drugs (moderate) — and none of Lamotrigine’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Iboga and Lamotrigine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. 2 of them are worth acting on rather than waiting out — marked below.

  • Unsteadiness Worth acting on Additional detail

    Iboga

    “Ibogaine, a constituent of iboga, taken orally in doses ranging from 10-32 mg/kg may cause confusion, dizziness, dream-like states, hallucinations, and headaches. Ibogaine in doses up to 25 mg/kg has been associated with cases of extreme sensitivity to color and sound, sweating, cold sensations, increased energy and appetite, insomnia, and a strong aphrodisiac effect.”

Overlapping uses

What Lamotrigine Is Prescribed For, and What Iboga Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Lamotrigine is a prescription medicine with approved uses on its FDA label. Iboga is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Lamotrigine is prescribed for: Lamotrigine is used to treat several types of seizures in adults and children aged 2 and older — including partial-onset seizures, generalized tonic-clonic (grand mal) seizures, and seizures related to Lennox-Gastaut syndrome. In older teens and adults, it can also be used alone (monotherapy) after transitioning off another seizure medicine. For adults with bipolar I disorder, lamotrigine is used as a maintenance treatment — meaning it helps delay the return of mood episodes like depression, mania, or mixed states. It is not approved to treat an active manic or mixed episode that's happening right now.

Iboga has been studied for:

  • Depression studied, not established Iboga has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Iboga for depression

    Although there is interest in using oral iboga for depression, there is insufficient reliable information about the clinical effects of iboga for this condition.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Lamotrigine on your own; if you are taking Iboga for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Lamotrigine page

“Alcohol, ordinary beer or wine, sits at the top of the interaction list for lamotrigine (Lamictal), with well-documented added sedation, and it sets the tone for a list I would treat with real care. Of the 116 supplements and herbs on file, 78 have sedative effects of their own, so the biggest theme by far is stacked drowsiness and slo…”

About Iboga

What is Iboga?

Iboga
  • Drug and alcohol addiction
  • Opioid withdrawal
  • Spiritual and ceremonial rituals
  • Fatigue and stimulant effects
  • Mood and emotional issues

Iboga is a Central African shrub whose root bark contains ibogaine, a powerful hallucinogenic compound studied mainly for addiction. It carries serious safety risks, including dangerous heart rhythm changes and deaths, and ibogaine is illegal in the United States and many other countries. We do not recommend its use outside of tightly controlled research settings.

Tabernanthe iboga · Apocynaceae · Root bark · Root bark powder, capsules, extracts; the isolated alkaloid ibogaine (a controlled substance in many countries)

An interaction check asks whether these two react with each other — it does not ask whether Iboga is a good idea for someone in your situation. Here is what our Iboga record says about it on its own.

Iboga: dosing

There is no established safe or standard dose of Iboga or ibogaine for any condition. Because the compound is unpredictable and can harm the heart, doses cannot be recommended here.Ibogaine is a controlled substance in the United States, so it cannot be legally bought or used as a supplement. Do not attempt to dose yourself with Iboga.

Taking Iboga and Lamotrigine Together: Common Questions

Is it safe to take Iboga with Lamotrigine?
We do not list a known interaction between Iboga and Lamotrigine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Iboga and Lamotrigine have any of the same side effects?
Yes — our sources link each of them separately to 9 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Iboga and Lamotrigine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Iboga in each. That is a conversation for your prescriber, especially if Lamotrigine is being adjusted to a target.
How was the Iboga and Lamotrigine combination checked?
Interactions in our licensed database are recorded against drug classes. Lamotrigine is filed under 5 classifications, and Iboga has documented interactions with 6 drug classes — none of Lamotrigine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Iboga interact with any other medications?
Yes. Iboga has 502 documented drug interactions in our database — Lamotrigine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Lamotrigine interact with any supplements?
Yes. Lamotrigine has documented interactions with 116 supplements in our database — Iboga is not one of them. The Lamotrigine interaction page linked on this page lists every one, ranked by severity.
