Rabdosia Rubescens and Elagolix Sodium

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

Why Are There 2 Interactions?

Rabdosia Rubescens interacts with whole categories of medication. Elagolix Sodium falls into 2 of those categories, so it can interact with Rabdosia Rubescens 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 Elagolix Sodium

Elagolix Sodium falls under P-GLYCOPROTEIN SUBSTRATES — the group Rabdosia Rubescens interacts with.

Rabdosia rubescens might increase levels of p-glycoprotein substrates. In vitro research shows that Rabdosia rubescens extract inhibits p-glycoprotein levels and activity. Drugs that might be affected include some chemotherapeutic agents (doxorubicin, etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir, saquinavir), H2 antagonists (cimetidine, ranitidine), some calcium channel blockers (diltiazem, verapamil), digoxin, corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.
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 situation with Orilissa (elagolix) and this herb. Elagolix is carried around your body partly by a transporter pump called p-glycoprotein, which normally helps push the drug back out and limit how much builds up. In test-tube studies, Rabdosia rubescens seems to slow that pump down. If that held true in people, a bit more elagolix could stay in your system, which might mean stronger effects or more side effects like hot flashes, headaches, nausea, trouble sleeping, or mood changes.

The key thing to know is that this is only laboratory evidence, not proven in humans, so it may not amount to much in real life. Still, since safety data for this herb is thin, I'd run it past your pharmacist or doctor before combining the two rather than guessing.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

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

In vitro research shows that oridonin, a constituent of Rabdosia rubescens, induces cytochrome P450 3A4 (CYP3A4) enzyme. Also, in an animal model, oridonin induces a gene homologous to CYP3A4. So far, this interaction has not been reported in humans. However, watch for a decrease in the levels of drugs metabolized by CYP3A4 in patients taking Rabdosia rubescens. Some drugs metabolized by CYP3A4 that might be affected are some benzodiazepines such as alprazolam (Xanax), diazepam (Valium), midazolam (Versed), triazolam (Halcion); calcium channel blockers such as amlodipine (Norvasc), diltiazem (Cardizem, Dilacor, others), felodipine (Plendil), verapamil (Calan, Verelan, others); cyclosporine (Neoral, Sandimmune); some HIV antivirals such as indinavir (Crixivan), ritonavir (Norvir), saquinavir (Fortovase, Invirase); some HMG CoA reductase inhibitors such as atorvastatin (Lipitor), lovastatin (Mevacor); some macrolide antibiotics such as erythromycin and clarithromycin (Biaxin); quinidine; and many others.

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

Here's the gist for Orilissa (elagolix). Your body relies on a liver enzyme called CYP3A4 to help process this medication. Lab research suggests that a compound in Rabdosia rubescens, called oridonin, may speed up that enzyme. If that happened in real life, your body could clear elagolix a little faster, which might lower its levels and make it less effective at controlling your endometriosis pain and bleeding.

I want to keep this in perspective, though. This concern comes only from test-tube and animal studies, and it has not been reported in actual patients. So the real-world risk is uncertain. Still, before adding this herb, it's worth a quick chat with your pharmacist or doctor so they can weigh in.

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.”
