Kava and Atogepant

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

Why Are There 2 Interactions?

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

Moderate

P-GLYCOPROTEIN SUBSTRATES

1 of 2

Why this applies to Atogepant

Atogepant falls under P-GLYCOPROTEIN SUBSTRATES — the group Kava interacts with.

It is unclear if kava inhibits P-glycoprotein (P-gp); research is conflicting.
In vitro research shows that kava can inhibit P-gp efflux. However, a clinical study in healthy volunteers shows that taking kava standardized to provide 225 mg kavalactones daily for 14 days does not affect the pharmacokinetics of digoxin, a P-gp substrate. It is possible that the use of other P-gp substrates or higher doses of kava might still inhibit P-gp.
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 gist for your migraine medicine, atogepant (Qulipta). Your body uses a kind of cellular bouncer called P-glycoprotein to help shuttle this drug out. In the test tube, kava looks like it might slow that bouncer down, which in theory could let a little more atogepant build up. If that happened, you might notice more of its usual side effects, like nausea, constipation, tiredness, or low appetite.

That said, the real-world evidence is thin and actually a bit reassuring. A human study using kava alongside another P-gp drug found no meaningful change. So this is mostly a lab-based concern, not a proven problem. Still, since kava carries its own liver risks, I'd run the combo by your pharmacist or doctor before starting it.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Atogepant also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

It is unclear if kava inhibits CYP3AA; research is conflicting.
Although in vitro research suggests that kava inhibits CYP3A4, more robust clinical evidence shows that kava has no effect on CYP3A4. In a clinical study in healthy volunteers, taking kava 1000 mg twice daily (containing a daily dose of 138 mg kavalactones) for 28 days had no effect on CYP3A4 activity.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the short version on combining kava with atogepant (Qulipta). Atogepant is cleared from your body by a liver enzyme called CYP3A4. In theory, if kava slowed that enzyme down, atogepant could build up a bit and you might notice more of its usual side effects, like nausea, tiredness, or constipation.

But here's the reassuring part: while early lab studies hinted kava might block CYP3A4, a better human study showed it actually had no real effect on that enzyme. So a meaningful interaction here is unlikely. My bigger concern with kava is its rare risk of liver damage, which matters because the liver handles atogepant. Please run this by your pharmacist or doctor before starting kava.

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.

This page covers Kava only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Atogepant page lists 144 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 103 moderate · 38 minor.

From our pharmacist’s overview on the Atogepant page

“Grapefruit is the single interaction I would want every Qulipta user to know first. Atogepant, a preventive migraine medicine, is cleared by a liver enzyme called CYP3A4, and grapefruit juice blocks that enzyme, so the drug can build up and side effects become more likely.”

About Kava

What is Kava?

Kava

  • Menopausal symptoms

Kava is a Pacific Island plant traditionally used to promote relaxation and ease anxiety, and some studies suggest it may help mild anxiety. However, kava has been linked to rare but serious liver damage, so it should be used with caution, avoided by people with liver problems, and only used after talking with your pharmacist or doctor.

Qulipta (atogepant) is used to prevent migraines in adults — both episodic migraine (fewer monthly migraine days) and chronic migraine (15 or more headache days a month). It is a preventive treatment, meaning you take it regularly to reduce how often migraines happen, not to stop a migraine that has already started.
