How does this medication work? What will it do for me?
Daridorexant belongs to the class of medications called hypnotics. It is used to treat difficulties falling or staying asleep. There is a chemical called orexin, which binds to certain receptors in the brain to keep you awake. Daridorexant works by temporarily blocking these receptors.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Are there any other precautions or warnings for this medication?
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 this medication.
Alcohol and other medications that cause drowsiness: Do not combine this medication with alcohol or other medications that cause drowsiness (e.g., antidepressants, sleeping pills, anxiety medications) since additional drowsiness can occur, which can be dangerous.
Breathing: Like other medications that affect the nervous system, daridorexant can suppress breathing. If you have asthma, or another lung disease that increases your risk for breathing difficulties, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Daytime drowsiness/reduced alertness: Even when taken at the lowest effective dose, daridorexant may cause drowsiness or mental impairment in the daytime. This impairment may not cause symptoms but can cause unsafe activity, such as poor judgement, focus, or reaction time. If you notice that you are drowsy or more frequently want to sleep, stop taking the medication and contact your doctor.
Depression: Daridorexant, 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 this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication contact your doctor as soon as possible.
Performing activities while not fully awake: People taking daridorexant 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 this medication should contact the person's doctor immediately if they notice any of these unusual behaviours.
Other sleep conditions: This medication 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.
Daridorexant 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: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if daridorexant passes into breast milk. If you are breast-feeding and taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
