Getting Patients Started With DAYVIGO® (lemborexant) CIV


This is an advertisement paid for by Eisai Inc.

This brief tool provides information to help pharmacists prepare for counseling sessions with patients prescribed DAYVIGO®(lemborexant), a dual orexin receptor antagonist that is indicated for the treatment of adult patients with insomnia, characterized by difficulties with sleep onset and/or sleep maintenance.1 Pharmacists have an opportunity to counsel patients and help them get started with DAYVIGO at every prescription pickup.


As a part of the counseling session, consider the following steps:

  • Review key administration instructions.
  • Set patient expectations of treatment.
  • Emphasize the importance of sleep hygiene.

For patients seeking additional support or information, a savings program is available for eligible patients as well as patient education and support tools.


•DAYVIGO is contraindicated in patients with narcolepsy

Please see additional selected safety information below and full Prescribing Information.


DAYVIGO is supplied as 5 mg and 10 mg tablets. The recommended starting dose of DAYVIGO is 5 mg.

  • The dose may be increased to the maximum recommended dose of 10 mg based on clinical response and tolerability.
  • There is no need for dose adjustment based on age, sex, BMI, and renal impairment.
  • Patients aged 65 years or older should use caution when taking DAYVIGO 10 mg.
  • Patients with severe renal impairment may experience an increased risk of somnolence.

For patients with moderate hepatic impairment, the maximum recommended dose is 5 mg once per night.

  • DAYVIGO is not recommended for patients with severe hepatic impairment.
  • Patients with mild hepatic impaiment may experience an increased risk of somnolence.

Advise patients to avoid concomitant use of DAYVIGO with strong or moderate CYP3A inhibitors and inducers.

  • The maximum recommended dose of DAYVIGO is 5 mg no more than once per night when coadministered with weak CYP3A inhibitors.

Provide patients with these key administration instructions for DAYVIGO:

  • Take DAYVIGO immediately before getting into bed and only if they can stay in bed for a full night (≥ 7 hours) before the planned time of awakening.
  • The effect of DAYVIGO may be delayed if taken with or soon after a meal.
  • DAYVIGO should not be taken more than once per night.


Remind patients to read the FDA-approved patient labeling (Medication Guide) that comes with their DAYVIGO prescription.

Review the Patient Counseling Information in Section 17 of the DAYVIGO Prescribing Information to advise patients of potential side effects.


As it may take a few days to assess patient response, the prescribing physician may have recommended a trial period of 7 to 10 days of DAYVIGO (lemborexant) treatment.

  • Remind patients that it is important to give DAYVIGO a trial of at least a week and see how it’s working.
  • Inform your patients that they may feel differently when they fall asleep and stay asleep while taking DAYVIGO than their previous experience or expectations.
  • Advise patients to follow up with their provider after 7 to 10 days—their doctor will determine if insomnia persists and will reassess for comorbid conditions.


In addition to treatment, patients may benefit from improving their sleep hygiene—habits that can help them optimize sleep. During counseling, ask your patients about their sleep patterns, such as:

  1. Do you take any medications before bedtime?
  2. Are you currently taking or have you tried taking any medications to help you sleep?
  3. How much time elapses between consuming your last meal and drink of the day and going to bed?
  4. Do you have trouble falling asleep, staying asleep, or both?
  5. How long have you been experiencing insomnia symptoms?

Counsel your patients on examples of good sleep hygiene.

Encourage your patients to:

  • Ensure adequate exposure to natural light.
  • Exercise daily.
  • Limit daytime napping.
  • Have a regular bedtime routine and stick to a sleep schedule with the same bedtime and wake-up time (even on weekends).
  • Establish a pleasant sleep environment, create a relaxing ritual, and prepare their bedroom (eg, turn off lights, remove their phone or laptop, and keep their bedroom cool [between 60° and 70°F]).
  • Avoid stimulants (eg, caffeine and nicotine) in the evening close to bedtime.
  • Avoid alcohol use on days they plan on taking DAYVIGO.
  • Avoid late evening meals, as DAYVIGO also may take longer to work if they take it with or soon after a meal.

Central Nervous System (CNS) Depressant Effects and Daytime Impairment:
DAYVIGO can impair daytime wakefulness. CNS depressant effects may persist in some patients up to several days after discontinuing DAYVIGO. Prescribers should advise patients about the potential for next-day somnolence.
Driving ability was impaired in some subjects taking DAYVIGO 10 mg. Risk of daytime impairment is increased if DAYVIGO is taken with less than a full night of sleep remaining or at a higher than recommended dose. If taken in these circumstances, patients should not drive or engage in activities requiring mental alertness.
Use with other classes of CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol) increases the risk of CNS depression, which can cause daytime impairment. Dosage adjustments of DAYVIGO and concomitant CNS depressants may be necessary when administered together. Use of DAYVIGO with other insomnia drugs is not recommended. Patients should be advised not to consume alcohol in combination with DAYVIGO.
Because DAYVIGO can cause drowsiness, patients, particularly the elderly, are at a higher risk of falls.
Sleep Paralysis, Hypnagogic/Hypnopompic Hallucinations, and Cataplexy-Like Symptoms:
Sleep paralysis, an inability to move or speak for up to several minutes during sleep-wake transitions, hypnagogic/hypnopompic hallucinations, including vivid and disturbing perceptions can occur with DAYVIGO. Prescribers should explain these events to patients.
Symptoms similar to mild cataplexy can occur with DAYVIGO and can include periods of leg weakness lasting from seconds to a few minutes, can occur either at night or during the day, and may not be associated with identified triggering event (e.g., laughter or surprise).
Complex Sleep Behaviors:
Complex sleep behaviors, including sleep-walking, sleep-driving, and engaging in other activities while not fully awake (e.g., preparing and eating food, making phone calls, having sex), have been reported to occur with the use of hypnotics such as DAYVIGO. Events can occur in hypnotic-naïve and hypnotic-experienced persons. Patients usually do not remember these events. Complex sleep behaviors may occur following the first or any subsequent use of DAYVIGO, with or without the concomitant use of alcohol and other CNS depressants. Discontinue DAYVIGO immediately if a patient experiences a complex sleep behavior.
Patients with Compromised Respiratory Function:
The effect of DAYVIGO on respiratory function should be considered for patients with compromised respiratory function. DAYVIGO has not been studied in patients with moderate to severe obstructive sleep apnea (OSA) or chronic obstructive pulmonary disease (COPD).
Worsening of Depression/Suicidal Ideation:
Incidence of suicidal ideation or suicidal behavior, as assessed by questionnaire, was higher in patients receiving DAYVIGO than placebo (0.3% for DAYVIGO 10 mg, 0.4% for DAYVIGO 5 mg, and 0.2% for placebo). In primarily depressed patients treated with hypnotics, worsening of depression and suicidal thoughts and actions (including completed suicides) have been reported. Suicidal tendencies may be present in such patients and protective measures may be required. Intentional overdose is more common in this group of patients; therefore, the lowest number of tablets that is feasible should be prescribed at any one time. The emergence of any new behavioral sign or symptom of concern requires careful and immediate evaluation.
Need to Evaluate for Comorbid Diagnoses:
Treatment of insomnia should be initiated only after careful evaluation of the patient. Re-evaluate for comorbid conditions if insomnia persists or worsens after 7 to 10 days of treatment. Worsening of insomnia or the emergence of new cognitive or behavioral abnormalities may be the result of an unrecognized underlying psychiatric or medical disorder and can emerge during the course of treatment with sleep-promoting drugs such as DAYVIGO.

•The most common adverse reaction (reported in 5% of patients treated with DAYVIGO and at least twice the rate of placebo) with DAYVIGO was somnolence (10% for DAYVIGO 10 mg, 7% for DAYVIGO 5 mg, 1% for placebo).

CYP3A Inhibitors: The maximum recommended dose of DAYVIGO is 5 mg no more than once per night when co-administered with weak CYP3A inhibitors. Avoid concomitant use of DAYVIGO with strong or moderate CYP3A inhibitors.
CYP3A Inducers: Avoid concomitant use of DAYVIGO with moderate or strong CYP3A inducers.

Pregnancy and Lactation: There is a pregnancy exposure registry that monitors pregnancy outcomes in women who are exposed to DAYVIGO during pregnancy. Healthcare providers are encouraged to register patients in the DAYVIGO pregnancy registry by calling 1-888-274-2378. There are no available data on DAYVIGO use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
There are no data on the presence of lemborexant in human milk, the effects on the breastfed infant, or the effects on milk production. Infants exposed to DAYVIGO through breastmilk should be monitored for excess sedation.
Geriatric Use: Exercise caution when using doses higher than 5 mg in patients ≥65 years old.
Renal Impairment: Patients with severe renal impairment may experience an increased risk of somnolence.
Hepatic Impairment: The maximum recommended dose of DAYVIGO is 5 mg in patients with moderate hepatic impairment. DAYVIGO is not recommended in patients with severe hepatic impairment. Patients with mild hepatic impairment may experience an increased risk of somnolence.

•DAYVIGO is a Schedule IV-controlled substance.
•Because individuals with a history of abuse or addiction to alcohol or other drugs may be at increased risk for abuse and addiction to DAYVIGO, follow such patients carefully.
