Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Dayvigo (Lemborexant).
Alcohol and other medications that cause drowsiness: Do not combine Dayvigo (Lemborexant) with alcohol or other medications (e.g., antidepressants, sleeping pills, anxiety medications) that cause drowsiness since additional drowsiness can occur, which can be dangerous. Taking Dayvigo (Lemborexant) with other medications that cause drowsiness increases the likelihood of experiencing drowsiness or decreased alertness during the day.
Breathing: Like other medications that affect the nervous system, Dayvigo (Lemborexant) can suppress breathing. If you have Asthma, or another lung disease that increases your risk for breathing difficulties, discuss with your doctor how Dayvigo (Lemborexant) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dayvigo (Lemborexant), and whether any special monitoring is needed.
Daytime drowsiness/reduced alertness: Even when taken at the lowest effective dose, Dayvigo (Lemborexant) may cause drowsiness or mental impairment in the daytime. The risk of daytime drowsiness is increased if Dayvigo (Lemborexant) is taken with less than a full night of sleep remaining (at least 7 hours). Avoid driving, operating machinery, or performing other tasks that require sound judgement until you have determined how you are affected by Dayvigo (Lemborexant).
Depression: Dayvigo (Lemborexant), like other medications to help with sleep, may cause mood swings and symptoms of depression, including thoughts of self-harm or suicide. If you have depression or a history of depression, discuss with your doctor how Dayvigo (Lemborexant) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dayvigo (Lemborexant), and whether any special monitoring is needed.
If you experience worsening or new symptoms of depression or such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking Dayvigo (Lemborexant) contact your doctor as soon as possible.
Inappropriate Use: Like other medications for help with sleep problems, Dayvigo (Lemborexant) can be abused or used inappropriately. If you have a history of past or current Substance Use Problems you may be at greater risk of developing abuse or addiction while taking Dayvigo (Lemborexant).
Lactose: Dayvigo (Lemborexant) contains lactose. If you have hereditary problems of galactose intolerance, lactase deficiency, or glucose-galactose malabsorption, discuss the appropriateness of Dayvigo (Lemborexant) with your doctor.
Liver function: Liver disease or reduced liver function may cause Dayvigo (Lemborexant) to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Dayvigo (Lemborexant) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Dayvigo (Lemborexant), and whether any special monitoring is needed.
Memory disturbance: Medications such as Dayvigo (Lemborexant) can cause memory loss (amnesia). Amnesia of varying severity has been reported following normal doses of Dayvigo (Lemborexant).
Performing activities while not fully awake: People taking Dayvigo (Lemborexant) may perform activities such as sleepwalking, driving, preparing and eating food, and making phone calls while not fully awake and are unaware of their actions. The next morning, they may not remember what happened. This may be more likely to occur if you use alcohol or other sedative medications. If you discover this has happened to you, contact your doctor immediately.
Family members or caregivers of people who are taking Dayvigo (Lemborexant) should contact the person's doctor immediately if they notice any of these unusual behaviours.
Other sleep conditions: Dayvigo (Lemborexant) may cause episodes of sleep paralysis, an inability to move or speak when you are awakening. These episodes may last seconds to several minutes before normal movement is possible.
Dayvigo (Lemborexant) has also been associated with muscle weakness and waking dreams, mental images that occur during the transition from sleep to wakefulness and also when falling asleep.
Pregnancy: Dayvigo (Lemborexant) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Dayvigo (Lemborexant), contact your doctor immediately.
Breast-feeding: It is not known if Dayvigo (Lemborexant) passes into breast milk. If you are a breast-feeding mother and are taking Dayvigo (Lemborexant), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using Dayvigo (Lemborexant) have not been established for children.
