Corn Poppy and Lemborexant

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

Moderate

CNS DEPRESSANTS

Why this applies to Lemborexant

Lemborexant falls under CNS DEPRESSANTS — the group Corn Poppy interacts with.

Theoretically, concomitant use of corn poppy with CNS depressants might increase the risk of sedation.
Animal research suggests that corn poppy leaf extract has sedative effects.
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 simple version: Lemborexant (Dayvigo) already works by calming activity in your brain to help you sleep. Corn poppy has been studied mostly in animals, where its leaf extract seemed to have a mild calming, sleepy effect. So the worry is that stacking the two could add up and make the sedation stronger than you expect.

In real life that might mean feeling extra drowsy, groggy, dizzy, or slow the next morning, which can affect things like driving or steady walking. To be clear, this is a theoretical concern based on lab and animal data, not strong human studies, so it may not amount to much. Still, since both can make you sleepy, it's worth a quick chat with your pharmacist or doctor before combining them.

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 Corn Poppy

What is Corn Poppy?

Corn Poppy
  • Cough and sore throat
  • Sleep and restlessness
  • Mild pain
  • Anxiety and nervousness
  • Digestive complaints

Corn poppy is a red-flowered plant traditionally used in teas and syrups for cough, sleep, and mild pain. Solid human research is very limited, so its benefits are not well proven, and unlike its relative the opium poppy, it contains only small amounts of weak alkaloids. Talk to a pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.
