Dayvigo®
Dayvigo is a newer treatment for insomnia, designed to help adults fall asleep more easily and stay asleep throughout the night.
Dayvigo belongs to a class of medicines called orexin receptor antagonists.
Orexin is a natural chemical in the brain that promotes wakefulness. By blocking orexin receptors (OX1 and OX2), Dayvigo helps the brain transition smoothly from a wakeful state into sleep.
One of its key characteristics is its relatively long elimination half-life (approximately 47.4–50.6 hours). This allows it to:
- Support sleep onset
- Provide stable sleep maintenance
- Reduce nighttime awakenings
If you struggle with waking up during the night or too early in the morning, Dayvigo may offer consistent overnight support.
- The usual adult dose is 5 mg once daily, taken immediately before bedtime.
- Depending on symptoms and physician judgment, the dose may be adjusted.
- The maximum dose is 10 mg once daily.
- Do not exceed 10 mg per day.
Important:
Avoid taking Dayvigo with food or immediately after a meal, as this may delay its sleep-inducing effect. It is best taken on an empty stomach or just before bedtime.
As with all medications, side effects may occur.
Common side effects include:
- Somnolence (drowsiness): 10.7%
- Headache: 4.2%
- Fatigue: 3.1%
- Vivid or unusual dreams
- Sleep paralysis (temporary inability to move when falling asleep or waking)
If side effects persist or worsen, consult your healthcare provider.
Why people choose Davyigo®
For nighttime or early morning awakenings
Because of its longer duration of action, Dayvigo is particularly suitable for individuals who wake frequently during the night, wake too early and struggle to fall back asleep, or want consistent, uninterrupted sleep through the morning.
Flexible use with certain medications
Some antibiotics or antifungal medications affect how sleep medicines are processed in the body. With Dayvigo, dose adjustment (to 2.5 mg) may allow continued treatment under medical supervision.
Lower risk of dependence
Dayvigo works through a different mechanism than traditional benzodiazepine sleep medications. It is considered to have a relatively lower risk of dependence.
