Dayvigo: A New Medication for Insomnia

According to research, insomnia affects about 10% to 30% of the adult population, reaching as high as 50% to 60% in some demographics. An adult requires approximately seven to nine hours of sleep to maintain good physical and mental health. And inadequate rest hampers a person’s productivity at work and their overall quality of life.

There are three major ways to treat or manage sleep disorders: pharmacological, psychotherapy, or their combination. A patient’s treatment plan depends on whether he or she has a temporary or chronic sleep disorder. To prescribe treatment, the clinician also considers the severity of the disorder, and overall health conditions, among other factors.

When it comes to medicines, there are many options available. And while there are drugs that have been used for decades, there are also newer ones that can be more effective for some patients. One of them is Dayvigo medication, commonly used for chronic insomnia, and we will review it in the article below.

Prolonged insufficient sleep may cause problems with mental and physical health. Prevent unwanted outcomes, get help today.

What is Dayvigo

Dayvigo is a new sleep medication with the generic name lemborexant. It is meant for persons above 18 years old. Dayvigo is a controlled substance classified as a schedule IV prescription drug and is an FDA-approved medication.

Dayvigo (lemborexant), similar to Belsomra (suvorexant) and Quviviq (daridorexant), is an orexin receptor antagonist that regulates the sleep-wake cycle. Another benefit of Dayvigo is fewer side effects and its lower risk of abuse and addiction compared to Benzos drugs like Ambien.

How Dayvigo Treats Insomnia

Being an orexin receptor antagonist, Dayvigo acts on the sleep centers in the brain. This new sleeping pill targets the orexin hormone, also known as hypocretin, which is involved in brain arousal. By blocking orexin receptors, this medication slows the thought processes and ability to react fast. However, it does not make one constantly sleepy but helps a person fall asleep fast and sleep for at least seven hours.

Dayvigo Dosage for Insomnia

Dayvigo is an oral sleep aid available in 5 mg and 10 mg tablets. The daily recommended dosage is 5 mg and should be administered right before bedtime. The recommended maximum daily dosage is 10 mg. A clinician may review the dose depending on the response or sleep disorder severity.

Here are some additional recommendations to consider:

  • before taking Dayvigo, a patient should ensure to have at least seven hours to sleep before the planned waking time;
  • Dayvigo can be taken with, without, or right after a meal;
  • Lemborexant may pose a serious risk of addiction to some people, particularly anyone who has or has had a substance abuse disorder.

To prevent severe side effects, a patient should take the medication as instructed by the clinician.
