Guggul and Lemborexant

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Lemborexant

Lemborexant falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Guggul interacts with.

Theoretically, guggul might reduce the effects of CYP3A4 substrates.
In vitro research shows that guggul constituents known as guggulsterones can induce CYP3A4.
Severity Moderate Likelihood Probable Evidence D

Interaction 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..

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

Here's the gist for your sleep aid. Lemborexant (Dayvigo) is cleared from your body by a liver enzyme called CYP3A4. Lab and animal studies hint that guggul (specifically its guggulsterone compounds) may speed that enzyme up. If it does, your body could break down lemborexant faster than usual, which might leave less of it working and make it less effective at helping you fall or stay asleep.

Keep in mind this is theoretical and based only on test-tube and animal research, not human studies, so it may not pan out in real life. Still, if you take Dayvigo and want to try guggul, check with your pharmacist or doctor first rather than adjusting anything on your own.

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.”
