Looking for a Dayvigo coupon? Dayvigo (lemborexant) is a brand-name prescription sleep medicine for adults with insomnia, and because there is no generic version yet, the cash price can be high.

Enter your ZIP code above to see today's Dayvigo price at pharmacies near you and compare your options in one place.
What is Dayvigo and how does it work?
Dayvigo is the brand name for lemborexant, a prescription medicine that is FDA-approved to treat insomnia in adults who have trouble falling asleep, staying asleep, or both. It belongs to a newer class of sleep medicines called dual orexin receptor antagonists (DORAs). Instead of broadly sedating the brain the way older sleep drugs do, Dayvigo works by blocking orexin, a natural brain chemical that promotes wakefulness. By quieting the "stay awake" signal, it helps the body transition into sleep.
Dayvigo is a non-benzodiazepine sedative-hypnotic and is a Schedule IV (C-IV) controlled substance. It is taken by mouth, and your prescriber will decide the right dose for you. This is general information only and not medical advice; always follow your provider's instructions.
Dayvigo cost: manufacturer savings card vs. Rx.com cash coupon
There are two main ways people lower the cost of Dayvigo. The first is the official manufacturer savings card from Eisai. Programs like this are typically limited to people with commercial (private) insurance and usually exclude those with government coverage such as Medicare or Medicaid. Terms, eligibility, and any savings amounts vary and can change, so check the official page for current details: Dayvigo prescription savings. If you are uninsured, on Medicare, or the manufacturer card is declined, that route may not help you.
The second way is an Rx.com cash coupon, which works differently. It is a cash-discount price you can use whether or not you have insurance, including if you have Medicare or the manufacturer card does not apply to you. There is currently no generic version of Dayvigo, so a generic is not yet an option for extra savings. To find the lowest current price, enter your ZIP above to see today's Dayvigo price at nearby pharmacies. If cost is a barrier, it is also worth asking your prescriber whether a manufacturer patient-assistance program is available for your situation.
Dayvigo alternatives and how it compares
Dayvigo is one of several prescription options for insomnia, and the best choice depends on your health history and what your prescriber recommends. Two other medicines in the same orexin-blocking class are Belsomra (suvorexant) and Quviviq (daridorexant). These work through a similar mechanism to Dayvigo.
Older, more familiar sleep medicines include Ambien (zolpidem) and Lunesta (eszopiclone), which are in a different, benzodiazepine-like class. Another option, Rozerem (ramelteon), works on the melatonin system rather than orexin. These medicines differ in how they work, their side effects, and their cost. Only your provider can tell you which is most appropriate for you, so use this as a starting point for that conversation.
Dayvigo safety and important warnings
Dayvigo does not carry a boxed warning, but there are important safety points to know. Because it is a central nervous system (CNS) depressant, it can cause next-day drowsiness and impairment. Do not drive or do anything that requires full alertness unless you can get at least 7 hours of sleep and feel fully awake. Avoid alcohol and other CNS depressants while taking it. Rarely, people have done complex sleep behaviors such as sleep-walking, sleep-driving, eating, making phone calls, or having sex while not fully awake and with no memory of it; if this happens, stop the medicine and contact your provider.
Dayvigo may worsen depression or cause suicidal thoughts, and some people experience sleep paralysis, temporary muscle weakness, or hallucinations while falling asleep or waking. Use caution if you have breathing problems, liver impairment, or a history of substance use. Dose adjustments may be needed with certain drugs that affect the CYP3A liver enzyme. This is not a complete list of risks and is not medical advice; talk with your provider or pharmacist about your full health history and all the medicines you take.
