What Is Dayvigo 10 mg Tablet?

Dayvigo Tablet contains lemborexant, a prescription medicine used for insomnia. It is a type of sleeping pill for adults who have trouble getting to sleep or staying asleep through the night. Rather than simply making you feel sleepy, Dayvigo works with the brain’s sleep-wake system to reduce the signals that keep you awake.

Lemborexant belongs to a group of medicines called dual orexin receptor antagonists (DORAs). It works by blocking two orexin receptors, known as OX1R and OX2R. Orexin is a natural chemical messenger in the brain that helps promote wakefulness and alertness. By reducing orexin signalling, lemborexant helps support the transition from wakefulness to sleep and may help maintain sleep through the night.

What Is Dayvigo Tablet Used For?

Dayvigo Tablet is used to manage insomnia, a condition in which a person has trouble falling asleep, staying asleep, or getting enough sleep. It contains lemborexant, which acts on the brain pathways involved in wakefulness and sleep.

Dayvigo may be prescribed when insomnia affects a person’s ability to get normal, restful sleep. The choice of treatment and strength depends on the individual’s condition and the advice of their healthcare professional.

How Does Dayvigo Work?

Dayvigo contains lemborexant, which works on the orexin system in the brain. Orexin is involved in keeping us awake and alert. Lemborexant reduces the activity of this system, helping the body move towards sleep.

In simple terms:

  • Lemborexant blocks orexin receptors: It acts on two receptors called OX1R and OX2R.
  • Wake-promoting signals are reduced: Blocking these receptors lowers the signals involved in maintaining wakefulness.
  • Sleep can become easier: By reducing these wake signals, Dayvigo helps support the normal sleep-wake process.

Because it acts on both OX1R and OX2R, lemborexant is known as a dual orexin receptor antagonist (DORA).

How to Take Dayvigo Tablet

Dayvigo should be taken exactly as directed by your doctor. The way it is taken can affect how well it works and how you feel afterward.

  • Take Dayvigo Tablet by mouth with a small amount of water.
  • It is generally taken shortly before going to bed, when you are ready to sleep.
  • Make sure you have enough time available for a full night’s sleep after taking the tablet.
  • Avoid taking it with or immediately after a meal because food may affect how quickly lemborexant takes effect.
  • Swallow the tablet as directed. Do not change the dose unless your doctor tells you to do so.

If you are unsure about when or how to take Dayvigo, ask your doctor or pharmacist for advice based on your prescription.

Dayvigo Tablet Dosage Information

The dose of Dayvigo is decided by a doctor based on the person’s sleep problem, other medicines, and overall health. Since this page is for the 10 mg tablet, it should only be taken in the amount prescribed by your healthcare professional.

Do not take more Dayvigo than prescribed, even if you feel that the medicine is not working as expected. Changing the dose without medical advice can increase the risk of unwanted effects.

Missed Dose

If you forget to take Dayvigo at bedtime, do not take it later if you do not have enough time left for a full night’s sleep. Follow your doctor’s instructions if you are unsure what to do.

Overdose

Taking more Dayvigo than prescribed may cause excessive sleepiness and other unwanted effects. If you think you have taken too much, seek medical advice promptly rather than taking another dose.
