Magnolia and Eszopiclone

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

Moderate

CNS DEPRESSANTS

Why this applies to Eszopiclone

Eszopiclone falls under CNS DEPRESSANTS — the group Magnolia interacts with.

Theoretically, concomitant use of large doses of magnolia bark and CNS depressants might have additive effects.
In vitro and animal research shows that constituents extracted from magnolia bark, especially honokiol and magnolol, have sedative effects. These effects may be due to the inhibition of catecholamine release and modulation of gamma-aminobutyric acid-A (GABA-A) receptors.
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

Eszopiclone (Lunesta) already works by calming brain activity to help you fall asleep, so the worry here is doubling up on that effect. Magnolia bark contains honokiol and magnolol, which in lab and animal studies act on the same GABA pathways and seem to produce a sedating, calming effect. Taken together with Lunesta, the concern is that the two could stack up and make you more drowsy than expected.

In real life that could mean feeling extra groggy, dizzy, unsteady on your feet, or hard to wake the next morning. Keep in mind this is theoretical, based only on test-tube and animal research, and is more of a concern with concentrated magnolia supplements than tiny culinary amounts. Before combining them, check with your pharmacist or doctor.

From our pharmacist’s overview on the Eszopiclone page

“Eszopiclone (Lunesta) is a sedative sleep medicine, so the danger that matters most here is ending up more sedated than you intended, and that danger is real on this page. Nine of the 195 interactions rate major, and I'd read those first.”

About Magnolia

What is Magnolia?

Magnolia
  • Anxiety and stress
  • Sleep problems
  • Digestive upset
  • Inflammation
  • Nasal congestion and allergies (flower bud)

Magnolia bark and flower buds have a long history in traditional Chinese and Japanese medicine, often for stress, sleep, and digestion. Modern human research is still limited, so we can't be sure how well it works for most uses. Talk with your pharmacist or doctor before trying it, especially if you take other medicines or are pregnant.

About Eszopiclone

What Is Eszopiclone Used For?

Brand name: Lunesta

Eszopiclone tablets — sold under the brand name Lunesta and as generics — are indicated for the treatment of insomnia. In clinical studies, eszopiclone helped people fall asleep more quickly (reduced sleep latency) and stay asleep through the night (improved sleep maintenance).

Clinical trials supporting its effectiveness lasted up to 6 months in adults and up to 2 weeks in elderly patients. Lunesta and eszopiclone generics are approved for this same indication across the available tablet formulations.
