Grape and Elagolix, Estradiol Norethindrone Acetate, Elagolix

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Elagolix, Estradiol Norethindrone Acetate, Elagolix

Elagolix, Estradiol Norethindrone Acetate, Elagolix falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Grape interacts with.

It is unclear if grape seed extract inhibits or induces CYP3A4; research is conflicting.
In vitro evidence suggests that grape seed extract might inhibit CYP3A4 enzymes. However, evidence from animal research shows that grape seed extract may induce CYP3A4 in the liver. So far, these interactions have 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 honest picture with Oriahnn (elagolix with estradiol and norethindrone) and grape seed extract. All three hormones in Oriahnn are handled in part by a liver enzyme called CYP3A4. Grape seed extract might nudge that enzyme, but the research is genuinely mixed: some lab studies suggest it slows CYP3A4 (which could let the drug build up), while animal studies hint it may speed it up (which could weaken it). So far, nothing like this has actually been seen in real people.

If levels went up, you might notice more hot flashes, headaches, mood changes, or nausea; if they dropped, your bleeding could be less controlled. This is theoretical and based only on lab and animal work, so I wouldn't lose sleep over an occasional handful of grapes. Before starting a concentrated grape seed supplement, though, just run it by your pharmacist or doctor.

From our pharmacist’s overview on the Elagolix, Estradiol Norethindrone Acetate, Elagolix page

“A woman managing heavy fibroid bleeding with Oriahnn (elagolix, estradiol, and norethindrone acetate) often reaches for supplements too, and here that deserves genuine care. Nearly all 161 entries change how much of the medication reaches her blood, mostly by speeding up or slowing down CYP3A4, the liver enzyme that processes it.”

About Elagolix, Estradiol, and Norethindrone

What Is Elagolix, Estradiol, and Norethindrone Used For?

Brand name: Oriahnn

Oriahnn is used to manage heavy menstrual bleeding linked to uterine leiomyomas — the medical name for fibroids, which are noncancerous growths in the uterus. It is approved for premenopausal women who experience abnormally heavy periods because of these fibroids.

Because the treatment can cause ongoing bone loss, it should be used for no more than 24 months. It is not a cure for fibroids — it manages symptoms while you are taking it.
