The bottom line No known interaction

We found no known interaction between Goat's Rue and Lemborexant in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist.

Interaction report

Goat's Rue and Lemborexant

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Lemborexant and Goat's Rue in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Goat's Rue safety at a glance

Goat's Rue overall Use caution The fresh plant can be toxic, and well-controlled human safety data on supplements are limited.

Pregnancy Avoid Not enough safety data exists, so it is best avoided during pregnancy.

Breastfeeding Use caution It is traditionally used to support milk supply, but quality and safety vary, so use only with professional guidance.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Lemborexant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lemborexant is filed under 3 classifications — cns depressants, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Goat's Rue has documented interactions with 1 drug class — the most serious being anticoagulant/antiplatelet drugs (moderate) — and none of Lemborexant’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Lemborexant’s Own FDA Label Lists

This is not an interaction — none of it involves Goat's Rue. These are the most notable effects listed in the ADVERSE REACTIONS section of Lemborexant’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 3 of them are worth acting on rather than waiting out — marked below.

Thoughts of self-harm Worth acting on mentioned in 10.1% of FDA reports for Lemborexant
Hallucinations Worth acting on
Low mood Worth acting on
Vivid dreams or nightmares
Drowsiness mentioned in 5.1% of FDA reports for Lemborexant
A fast or pounding heartbeat
Trouble sleeping
Tiredness
Headache mentioned in 3.4% of FDA reports for Lemborexant

From the ADVERSE REACTIONS section of the FDA label for Lemborexant. Read the label on DailyMed › Where a percentage is shown, it is the share of 2,745 voluntary FDA FAERS reports for Lemborexant that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Goat's Rue’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Goat's Rue side to compare — that is a limit of the record, not a statement that Goat's Rue has no side effects.

Everything else you take

See Every Supplement That Interacts With Lemborexant

This page covers Goat's Rue only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Lemborexant page lists 195 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: 1,4-butanediol (major), Activated Charcoal (major), Beer (major), Gamma-hydroxybutyrate (ghb) (major) and Grapefruit (major).

By severity: 9 major · 147 moderate · 39 minor.

From our pharmacist’s overview on the Lemborexant page

“Lemborexant (Dayvigo) works by quieting the brain's wake signals, so the biggest risks on this list come from anything else that sedates you. Alcohol sits at the top; a drink layered over a dose can deepen drowsiness into real impairment, and a few entries carry the added danger of slowed breathing.”

About Goat's Rue

What is Goat's Rue?

Boosting breast milk supply
Blood sugar support
Traditional digestive remedy
General tonic

Goat's rue is a traditional herb most often used by nursing parents to try to increase milk supply, and it has a historical link to diabetes research. Solid human evidence for either use is limited, and the plant can be toxic in larger amounts, so use it only under the guidance of a pharmacist or doctor.

Galega officinalis · Fabaceae · Above-ground parts (leaves, flowering tops, and seeds) · Tea, capsules, tincture, dried herb

An interaction check asks whether these two react with each other — it does not ask whether Goat's Rue is a good idea for someone in your situation. Here is what our Goat's Rue record says about it on its own.
