Understanding Dayvigo and Its Mechanism

What is Dayvigo?

Dayvigo is a brand-name oral tablet prescribed to treat insomnia in adults. It contains the active ingredient lemborexant and belongs to a class of drugs known as dual orexin receptor antagonists (DORAs). This medication is specifically designed to address difficulties with sleep onset and/or sleep maintenance, offering a new approach to managing persistent sleep issues.

As a Schedule IV controlled substance, Dayvigo is regulated due to its potential for misuse. However, compared to more traditional sleep medications, it appears to have a lower risk of dependence or withdrawal symptoms. This makes it an attractive option for those seeking long-term insomnia treatment.

How Dayvigo works

Dayvigo’s mechanism of action sets it apart from many other sleep medications. Instead of targeting the gamma-aminobutyric acid (GABA) receptor like most insomnia treatments, Dayvigo works by blocking the action of a brain chemical called orexin. This unique approach to treating sleep disorders has shown promising results in clinical studies.

The orexin neuropeptide signaling system plays a crucial role in regulating wakefulness. By preventing orexin from attaching to two specific receptors (OX1R and OX2R) in the brain, Dayvigo effectively suppresses the wake drive. This helps patients fall asleep faster and stay asleep longer, addressing both aspects of insomnia.

Lemborexant, the active ingredient in Dayvigo, has a stronger affinity for the OX2R receptor. This selective binding contributes to its effectiveness in reducing sleep latency and improving sleep maintenance compared to other treatments.

Conditions treated by Dayvigo

Dayvigo is FDA-approved for the treatment of insomnia in adults. It is specifically indicated for patients who experience difficulty falling asleep, staying asleep, or both. Clinical trials have demonstrated its efficacy in improving various sleep parameters.

In studies comparing Dayvigo to placebo and zolpidem (another common sleep medication), Dayvigo showed significant improvements in both objective and subjective sleep measures. Patients taking Dayvigo fell asleep an average of 26 minutes faster after 12 months of nightly treatment, compared to their baseline delay of about one hour.

Moreover, Dayvigo has shown benefits in delaying the time to first awakening by approximately 43 minutes. This improvement in sleep maintenance is particularly noteworthy, as it addresses one of the most common complaints among insomnia sufferers.

For adults over 55 years old, Dayvigo has demonstrated superior results compared to zolpidem extended-release. It improved time to sleep onset by about 20 minutes, versus only 7.5 minutes with zolpidem. Additionally, Dayvigo provided a modest improvement over zolpidem in waking after sleep onset, offering an extra seven to nine minutes of sleep before the first awakening.

These results highlight Dayvigo’s potential as an effective treatment option for adults struggling with various forms of insomnia, particularly those who have found limited success with other sleep medications.

Dosage and Administration

Recommended dosage

The standard recommended dose of Dayvigo for treating insomnia in adults is 5 mg taken once per night. Patients should take this dose immediately before going to bed, ensuring they have at least 7 hours available for sleep before their planned wake-up time. If the 5 mg dose proves ineffective in managing insomnia symptoms, a healthcare provider may consider increasing the dosage. The maximum recommended dose of Dayvigo is 10 mg once daily.

For patients with moderate hepatic impairment, the maximum recommended dose is limited to 5 mg no more than once per night. Dayvigo is not recommended for use in patients with severe hepatic impairment due to potential risks.

When co-administered with weak CYP3A inhibitors, the maximum recommended dosage of Dayvigo should not exceed 5 mg once per night. This precaution helps to mitigate potential drug interactions and maintain the medication’s safety profile.

How to take Dayvigo

Dayvigo comes in the form of oral tablets that should be swallowed whole. Patients should take their prescribed dose right before bedtime, within minutes of their typical sleep time. It’s crucial to take Dayvigo only when there are at least 7 hours available for sleep to avoid the risk of next-day drowsiness.

For optimal effectiveness, it’s recommended to take Dayvigo on an empty stomach. Consuming the medication with food or shortly after eating may delay its onset of action, potentially increasing the time it takes to fall asleep. Ideally, patients should take Dayvigo about 2 hours after their last meal of the day.

Patients should follow their healthcare provider’s instructions carefully and not alter their dosage without consulting their doctor first. It’s important to note that Dayvigo tablets should not be crushed, chewed, or split. If a patient has difficulty swallowing the tablet whole, they should discuss alternative options with their healthcare provider or pharmacist.

Missed dose instructions

If a patient misses a dose of Dayvigo, they should only take it if they still have at least 7 hours available for sleep before their planned wake-up time. Taking Dayvigo with less than 7 hours of sleep time remaining significantly increases the risk of excessive daytime sleepiness. This can interfere with daily activities, work performance, and the ability to operate machinery or drive safely.

In cases where less than 7 hours of sleep time is available, patients should skip the missed dose and resume their regular dosing schedule the following night. It’s crucial not to double up on doses to make up for a missed one, as this can increase the risk of side effects and next-day impairment.

To help maintain a consistent dosing schedule, patients may find it helpful to use medication reminders or alarms. However, they should always prioritize having sufficient sleep time over taking a missed dose. If patients frequently struggle with missed doses or have concerns about their medication schedule, they should consult their healthcare provider for guidance on managing their Dayvigo treatment effectively.

Potential Side Effects

Like any medication, Dayvigo can cause side effects. These may be temporary, lasting a few days to weeks. However, if side effects persist, become bothersome, or severe, patients should consult their doctor or pharmacist.

Common side effects

In clinical trials, several common side effects were reported by people taking Dayvigo. These include:

1. Excessive sleepiness, including daytime drowsiness
2. Nightmares or unusual dreams
3. Headache

It’s important to note that these side effects may be temporary and often resolve on their own. However, if they persist or become problematic, patients should discuss them with their healthcare provider.

Serious side effects

While less common, Dayvigo can potentially cause more serious side effects. These include:

1. Sleep paralysis: Symptoms may occur when falling asleep or waking up and can include an inability to move or speak, sweating, and difficulty breathing.
2. Temporary muscle weakness: This typically affects the legs and can last from a few seconds to a few minutes.
3. Heart palpitations: Patients may experience a sensation of their heart pounding or a fluttery feeling in their chest.
4. Hallucinations: These can occur when first falling asleep or waking up and may include feeling like one is falling or floating, or sensing, seeing, or hearing things that aren’t real.
5. Suicidal thoughts or behaviors: Symptoms may include changes in mood or behavior, loss of interest in usual activities, or persistent sadness.
6. Unusual sleep behaviors: This can include sleepwalking.
7. Severe allergic reactions: Although rare, these can occur and may include symptoms such as skin rash, itchiness, flushing, or more severe symptoms like swelling of the face, tongue, or throat.

When to seek medical attention

Patients should seek immediate medical attention if they experience:

1. Signs of a severe allergic reaction, such as swelling under the skin (especially in the eyelids, lips, hands, or feet), swelling of the tongue, mouth, or throat, or difficulty breathing.
2. Persistent or severe heart palpitations.
3. Frequent episodes of sleep paralysis or hallucinations that are bothersome.
4. Suicidal thoughts or behaviors.
5. Unusual sleep behaviors that pose a risk to the patient or others.

It’s crucial to take Dayvigo as prescribed, at bedtime, when there are at least 7 hours available for sleep. This can help reduce the risk of excessive sleepiness and other side effects. If patients experience any concerning side effects or have questions about their treatment, they should promptly consult their healthcare provider. The doctor may recommend changes to the treatment plan or explore alternative options if side effects are persistent or severe.
