Naratriptan brand name: Amerge.

Moderate Interaction
Medically reviewed by · Updated September 2026
The bottom line Moderate

Naratriptan falls into 2 drug categories that Iboga can interact with; the most serious is rated moderate. Theoretically, taking iboga with serotonergic drugs might increase levels of serotonin, resulting in additive effects with serotonergic drugs.

Interaction report

Iboga and Naratriptan

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Iboga interacts with whole categories of medication. Naratriptan falls into 2 of those categories, so it can interact with Iboga in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

SEROTONERGIC DRUGS

1 of 2

Why this applies to Naratriptan

Naratriptan falls under SEROTONERGIC DRUGS — the group Iboga interacts with.

Theoretically, taking iboga with serotonergic drugs might increase levels of serotonin, resulting in additive effects with serotonergic drugs.
Ibogaine, a constituent in iboga, has serotonergic effects. Theoretically, combining serotonergic drugs with iboga might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders. Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using iboga with serotonergic drugs.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing naratriptan (Amerge) with iboga. Naratriptan is a triptan that works on serotonin receptors to ease migraines. Iboga, through its active compound ibogaine, also nudges up serotonin activity in the brain. Stacking two things that both raise serotonin can, in theory, push serotonin too high. That can lead to serotonin syndrome, with symptoms like agitation, a racing heart, sweating, shivering, muscle twitching, or confusion.

To be fair, this warning is theoretical and based on how these substances work, not on real reports with this exact pair. Still, iboga carries serious heart rhythm risks on its own, so I'd steer clear of it. Please talk with your doctor or pharmacist before combining anything like this.

QT INTERVAL-PROLONGING DRUGS

2 of 2

Naratriptan also falls under QT INTERVAL-PROLONGING DRUGS.

Theoretically, iboga may have an additive effect with drugs that prolong the QT interval.
Numerous case reports suggest that ibogaine, a constituent in iboga, can cause QT interval prolongation.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing Iboga and naratriptan. Iboga (through ibogaine) has been linked in real-world case reports to a heart rhythm change called QT prolongation, where the heart's electrical reset takes longer than it should. Naratriptan is one of those triptan migraine medicines that can also nudge the QT interval a bit. Put them together and the worry is an additive effect, meaning the two could stack up and raise the risk of a dangerous, irregular heartbeat.

To be fair, this is mostly theoretical and rests on scattered case reports, not strong studies. Still, ibogaine carries serious heart risks (and is illegal in the U.S.), so this isn't a combination to take lightly. Please check with your doctor or pharmacist before mixing anything with your migraine medicine.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

From our pharmacist’s overview on the Naratriptan page

“Naratriptan (Amerge) treats migraines by acting on serotonin receptors, so it matters that 20 of the 50 supplements flagged for it can also push serotonin activity higher, raising the risk of serotonin syndrome, a dangerous overload. This is a list to approach with real caution, not a quick skim.”

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.

About Naratriptan

What Is Naratriptan Used For?

Brand name: Amerge

Naratriptan tablets are used to treat migraine headaches — with or without aura — when a migraine is already happening. It is a rescue treatment, meaning you take it during an attack, not daily to prevent migraines.

It is not used to prevent migraines, and it has not been proven effective for cluster headaches. Naratriptan should only be used when a doctor has clearly confirmed a diagnosis of migraine.
