Daridorexant (Quviviq) - Prescription Insomnia Treatment

What is Daridorexant?

Daridorexant belongs to a class of medicines called dual orexin receptor antagonists. It works by calming the brain’s “wakefulness signal,” helping reduce excessive alertness at night. This allows you to fall asleep more easily and stay asleep longer. It is sold under the brand name Quviviq and is a prescription-only medicine approved for adults with chronic insomnia.

Chronic insomnia is defined as sleep difficulties that have lasted at least three months and significantly affect your daytime life. People who may benefit from daridorexant often experience tiredness, trouble concentrating, or difficulties managing work and daily tasks.

Who Can Use Daridorexant?

Not everyone with insomnia is suitable for this medication. A qualified prescriber will review your medical history, current medications, and symptoms before deciding if daridorexant is right for you. In some cases, non-drug approaches or further assessment for other health conditions may be recommended.

You may be considered for daridorexant if you meet all of the following criteria:

• You are 18 or older
• Your insomnia has lasted 3 months or more
• Sleep problems occur on most nights and affect your daytime functioning
• You have tried CBT-I (Cognitive Behavioral Therapy for Insomnia) without sufficient improvement, or CBT-I is unavailable or unsuitable

How to Take Daridorexant

The usual adult dose is 50 mg once nightly, taken within 30 minutes of going to bed. Some patients may be prescribed 25 mg based on liver function, other medications, or clinical judgment.

Daridorexant can be taken with or without food, though taking it immediately after a large meal may slow its effects. If you forget a dose at bedtime, skip it and take your next dose at the usual time rather than taking it later in the night.

Safety and Side Effects

Most people tolerate daridorexant well. Common side effects may include headache, drowsiness, dizziness, nausea, or fatigue. Less commonly, people may experience sleep paralysis, unusual dreams or nightmares, sleepwalking, or allergic reactions such as rash.

Because daridorexant reduces wakefulness, it is important to avoid driving or operating machinery for at least 9 hours after taking it, especially when first starting treatment. Alcohol should also be avoided, as it can increase drowsiness. This medicine is not suitable during pregnancy or breastfeeding due to potential risks to infants.

Monitoring and Treatment Duration

Treatment should be as short as possible ( around 3 months) and stopped if insomnia does not improve. Patients who respond well can work with their prescriber on a long-term sleep management plan. Regular monitoring ensures that the treatment is safe and effective.
