Interaction report

Evodia and Elagolix Sodium

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

Why Are There 2 Interactions?

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Elagolix Sodium

Elagolix Sodium falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Evodia interacts with.

Theoretically, evodia might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that evodia extract inhibits hepatic CYP3A4. This effect has not been reported in humans.
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 short version: your body uses a liver enzyme called CYP3A4 to help clear elagolix (Orilissa) out of your system. In lab studies (test tube only), evodia appears to slow that same enzyme down. If that held true in people, elagolix could build up a bit more than usual, which might mean stronger effects and more of its typical side effects, like hot flashes, headaches, nausea, trouble sleeping, or mood changes.

I want to be honest about the evidence here. This is theoretical, based only on lab research, and it has not actually been shown in humans. So it's not a reason to panic. Still, since elagolix is an active medicine and not a prodrug, the smart move is to run the combination by your pharmacist or doctor before mixing the two.

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

2 of 2

Elagolix Sodium also falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS.

Theoretically, taking CYP3A4 inducers might decrease the levels and clinical effects of evodia.
Animal research shows that concomitant administration of dexamethasone, a known CYP3A4 inducer, with the alkaloid constituents of evodia significantly reduces the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents.
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 thing worth knowing if you're taking Orilissa (elagolix) and thinking about Evodia. In this case, the direction of the interaction is a little different than people expect. Elagolix can act as a mild CYP3A4 inducer, meaning it can speed up that liver enzyme. Evodia's active compounds (like evodiamine) appear to be broken down by that same enzyme, so a CYP3A4 inducer could clear them out faster and lower the levels of Evodia in your body. In plain terms, the medication may make the supplement less effective, not the other way around.

I want to be honest about how soft this evidence is. It comes from lab and animal studies only, so it's mostly theoretical. We don't expect a big change to how your elagolix works for endometriosis pain. Still, since Evodia isn't well studied in people, please run it by your pharmacist or doctor before combining the two.

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 Elagolix Sodium page

“The list of supplements that interact with elagolix sodium (Orilissa), a pill taken daily for endometriosis pain, is one I would read carefully, starting with its three major entries. Grapefruit can raise elagolix blood levels by blocking the liver enzyme that clears it, inviting more side effects.”

About Elagolix

What Is Elagolix Used For?

Brand name: Orilissa

Orilissa (elagolix) is used to treat moderate to severe pain associated with endometriosis — a condition where tissue similar to the uterine lining grows outside the uterus, causing significant pain.

This includes general pelvic pain as well as pain during sex (dyspareunia). How long you can take it depends on your dose and your overall health, so your prescriber will tailor the treatment duration to you.
