Dayvigo is a prescription medication used to treat insomnia in adults who have difficulty falling or staying asleep. Its active ingredient, lemborexant, belongs to a newer class of drugs called dual orexin receptor antagonists (DORAs). These drugs work by targeting the brain’s wake-promoting system, helping you fall asleep faster and stay asleep longer without causing traditional sedative side effects.
In this guide, you’ll learn what Dayvigo is, how it works, who it’s for, how to take it correctly, potential side effects, safety information, pricing insights, and answers to the most-searched questions online (Dayvigo vs other sleeping pills, cost without insurance, dosage, side effects, etc.).

What Is Dayvigo?
Dayvigo is the brand name for lemborexant, a once-daily oral medication approved by the FDA for the treatment of adult insomnia. It is available in 5 mg and 10 mg tablets, taken shortly before bedtime.
Unlike older sleep medications like benzodiazepines or non-benzodiazepine “Z-drugs,” Dayvigo works by blocking orexin—a chemical in your brain that keeps you awake. Because of its novel mechanism, Dayvigo tends to preserve natural sleep patterns and has a lower risk of dependence.
Available strengths:
- Dayvigo 5 mg tablet
- Dayvigo 10 mg tablet
Both are film-coated, round tablets taken orally.
How Does Dayvigo Work?
Dayvigo is a dual orexin receptor antagonist (DORA) that blocks orexin receptors (OX1R and OX2R) in the brain. Orexins are neurotransmitters that promote wakefulness, and by blocking them, Dayvigo allows your body to naturally transition into sleep.
- Not a sedative: It doesn’t knock you out or force sleep.
- Preserves sleep architecture: Allows for a more natural pattern of REM and deep sleep.
- Low addiction potential: Unlike older medications, it does not bind to GABA receptors.
Common Uses of Dayvigo
Doctors prescribe Dayvigo to treat:
- Sleep onset insomnia (difficulty falling asleep)
- Sleep maintenance insomnia (waking up during the night)
- Chronic insomnia in adults
It is not approved for use in children and should not be used for occasional sleeplessness or travel-related jet lag.

Step-by-Step Usage Tips:
