If you have insomnia (trouble sleeping), your doctor may recommend Quviviq. It’s a prescription drug that’s taken at bedtime to help you fall asleep and achieve a full night’s sleep.
For this purpose, Quviviq is only used in adults.
Quviviq comes as a tablet that you swallow. It contains the active ingredient daridorexant. (An active ingredient is what makes a drug work.) This drug belongs to a newer group of insomnia medications called dual orexin receptor antagonists (DORAs). It’s not currently available as a generic drug.
Read on to learn more about how Quviviq compares with Ambien, side effects Quviviq can cause, and more.
The active ingredient in Quviviq is daridorexant, while the active ingredient in Ambien is zolpidem. (An active ingredient is what makes a drug work.)
These medications belong to different drug groups and work in different ways. Quviviq is a kind of drug called a dual orexin receptor antagonist (DORA). It blocks brain signals that keep you awake. Ambien is a sedative-hypnotic. It increases brain signals that cause sleepiness. Both drugs can help you fall asleep faster and stay asleep longer.
The drugs have some similar and some different side effects. For example, both drugs can cause sleepiness that lasts into the next day, especially if you don’t get a full night’s sleep. Complex sleep behaviors, such as sleepwalking, are also possible with both drugs. With Ambien, abnormal thinking and behavior changes have been reported. But these side effects haven’t been reported with Quviviq.
Both Quviviq and Ambien are controlled substances that have a risk of misuse and of dependence. These risks are higher with Ambien. Withdrawal symptoms* can occur if you suddenly stop taking Ambien, but this doesn’t appear to be a problem with Quviviq. To learn more about Quviviq misuse and dependence, see the “Can Quviviq be misused?” section below.
There are several other differences between these drugs. To find out more, talk with your doctor.
To learn how Quviviq compares with other drugs used to treat insomnia, see the “What are some frequently asked questions about Quviviq?” section below. You can also talk with your doctor about how Quviviq compares with alternative treatments.
* Withdrawal symptoms are side effects that can occur when you stop taking a drug that your body has become dependent on.
Like most drugs, Quviviq may cause mild or serious side effects. The lists below describe some of the more common side effects that Quviviq may cause. These lists don’t include all possible side effects.
Keep in mind that side effects of a drug can depend on:
- your age
- other health conditions you have
- other medications you take
Your doctor or pharmacist can tell you more about the potential side effects of Quviviq. They can also suggest ways to help reduce side effects.
Mild side effects
Here’s a list of some of the mild side effects that Quviviq can cause. To learn about other mild side effects, talk with your doctor or pharmacist, or read Quviviq’s prescribing information.
Mild side effects of Quviviq that have been reported include:
* An allergic reaction is possible after taking Quviviq. But this side effect wasn’t reported in studies of the drug. To learn more about this side effect, see the “Allergic reaction” section below.
Mild side effects of many drugs may go away within a few days to a couple of weeks. But if they become bothersome, talk with your doctor or pharmacist.
Serious side effects
Serious side effects from Quviviq can occur, but they aren’t common. If you have serious side effects from Quviviq, call your doctor right away. But if you think you’re having a medical emergency, call 911 or your local emergency number.
Serious side effects of Quviviq that have been reported include:
- sleepiness, reduced alertness, and slowed reaction times the day after taking Quviviq, which could make driving dangerous*
- sleep paralysis (being unable to move or talk for a few seconds or minutes as you’re falling asleep or waking up)
- hallucinations (seeing or hearing things that aren’t real) that occur as you’re falling asleep or waking up
- complex sleep behaviors (doing activities while asleep, such as sleepwalking, eating, driving, making phone calls, or having sex)
- severe allergic reaction†
* This side effect is more likely if you don’t get at least 7 hours of sleep after taking Quviviq. It’s also more likely if you take a dose higher than your doctor recommends.
† An allergic reaction is possible after taking Quviviq. But this side effect wasn’t reported in studies of the drug. To learn more about this side effect, see the “Allergic reaction” section below.
Symptoms of a mild allergic reaction can include:
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, usually in your eyelids, lips, hands, or feet. They can also include swelling of your tongue, mouth, or throat, which can cause trouble breathing.

Quviviq is used to treat insomnia (trouble sleeping) in adults. It’s a sleep aid that’s prescribed for the following kinds of insomnia:
- Sleep onset insomnia (trouble falling asleep). With this kind of insomnia, it takes a long time for you to fall asleep.
- Sleep maintenance insomnia (trouble staying asleep). With this kind of insomnia, you wake in the night and having trouble falling back to sleep.
Your doctor may prescribe Quviviq if you have one or both of these sleep problems.
Quviviq belongs to a newer group of insomnia medications called dual orexin receptor antagonists (DORAs). Taking a DORA medication before going to bed reduces the brain signals that make you stay awake. This helps you fall asleep faster. It also helps you stay asleep throughout the night.
Find answers to some commonly asked questions about Quviviq.
How does Quviviq compare with Dayvigo and other alternatives?
Quviviq belongs to a newer group of insomnia treatments called dual orexin receptor antagonists (DORAs). Other drugs in this group include lemborexant (Dayvigo) and suvorexant (Belsomra). All these drugs are very similar. But Quviviq may start to work slightly faster than Dayvigo and Belsomra. It also works for a shorter time than these drugs, so it may be less likely to cause sleepiness the next day.
DORAs such as Quviviq work in a different way than other insomnia treatments. These include Z-drugs, such as zolpidem (Ambien), benzodiazepines such as temazepam (Restoril), and melatonin agonists such as ramelteon (Rozerem). DORAs reduce brain signals that keep you awake. Z-drugs and benzodiazepines work by increasing brain signals that cause sleepiness. Melatonin agonists help create a natural sleep-wake cycle.
These drugs have different pros and cons. To learn more about how Quviviq compares with Ambien, see the “What should I know about Quviviq vs. Ambien?” section above. For details about how Quviviq compares with other insomnia treatments, talk with your doctor.
Does Quviviq cause any long-term side effects?
No, Quviviq isn’t known to cause long-term side effects.
In studies, people took Quviviq for up to 12 months. No long-term side effects were reported in these studies. Taking the drug for long periods of time doesn’t appear to increase the risk of side effects.
If you have any concerns about long-term side effects while taking Quviviq, talk with your doctor.
Is Quviviq safe for older people to take?
Yes, Quviviq is generally safe for older people to take. But older people may have a higher risk of certain side effects.
In studies, people ages 65 years and older were more likely to have daytime sleepiness and fatigue (low energy) with Quviviq. These side effects could increase the risk of falls in older people. They could also make it unsafe for older people to drive while taking this drug.
If you’re age 65 years or older, your doctor may want to monitor you closely while you’re taking Quviviq.
There are several factors to consider before deciding whether Quviviq is right for you. For example, Quviviq may interact with other conditions you have and other medications you take. Be sure to talk with your doctor about your health history and other treatments before taking Quviviq.
Some things to consider are discussed below.
Taking a medication with certain vaccines, foods, and other things can affect how the medication works. These effects are called interactions.
Before taking Quviviq, be sure to tell your doctor about all medications you take, including prescription and over-the-counter kinds. Also describe any vitamins, herbs, or supplements you use. Your doctor or pharmacist can tell you about any interactions these items may cause with Quviviq.
For information about drug-condition interactions, see the “Warnings” section below.

This list does not contain all of the kinds of drugs that may interact with Quviviq. Your doctor or pharmacist can tell you more about these interactions and any others that may occur with Quviviq.
You should avoid eating grapefruit or drinking grapefruit juice while taking Quviviq. Grapefruit can stop your body from breaking down Quviviq, so the drug builds up in your body. This can increase your risk of side effects.
Quviviq can sometimes cause harmful effects in people who have certain conditions. This is known as a drug-condition interaction. Other factors may also affect whether Quviviq is a good treatment option for you.
Talk with your doctor about your health history before you take Quviviq. Factors to consider include those described below.
Allergic reaction. If you’ve had an allergic reaction to Quviviq or any of its ingredients, your doctor will likely not prescribe Quviviq. Ask them what other medications are better options for you.
Narcolepsy. People with narcolepsy have problems with the brain signals that keep them awake during the day. Quviviq blocks brain signals that keep people awake, so it could worsen narcolepsy. If you have narcolepsy,your doctor will likely not prescribe Quviviq. Ask your doctor what other medications are better options for you.
Liver problems. Quviviq is broken down by the liver. In people with liver problems, Quviviq could build up in the body and increase the risk of side effects. Due to this risk, your doctor will likely not prescribe Quviviq if you have severe liver problems. Ask your doctor what other medications are better options for you.
If you have moderate liver problems, your doctor may prescribe a Quviviq dosage that’s lower than usual.
Cataplexy. Drugs similar to Quviviq can sometimes cause mild cataplexy. This side effect wasn’t reported in studies of Quviviq, but it could happen. If you have cataplexy, Quviviq could worsen your symptoms. Talk with your doctor about whether Quviviq is right for you.
Breathing problems. Quviviq could worsen breathing problems, such as chronic obstructive pulmonary disease (COPD) or obstructive sleep apnea (OSA). It isn’t known whether Quviviq is safe for people with severe COPD or OSA. And it’s not known whether the drug is safe for people with moderate OSA who use continuous positive airway pressure (CPAP) therapy. If you have breathing problems, talk with your doctor about whether Quviviq is right for you.
Depression or suicidal thoughts. Insomnia medications can sometimes worsen depression and suicidal thoughts. This side effect wasn’t reported in studies of Quviviq, but it could happen. If you have a mental health condition such as depression, talk with your doctor about whether Quviviq is right for you. If you take Quviviq and experience worsening depression or suicidal thoughts, talk with your doctor right away.

It’s not likely. Quviviq is a controlled substance. Controlled substances are drugs regulated by the United States government because they may result in dependence or misuse. With Quviviq, these risks are low.
Misuse refers to taking a drug in way or for a use that’s not prescribed. An example is taking a drug prescribed to someone else. Dependence refers to the need to keep taking a drug to function, either physically or mentally.
In studies, there were no reports of Quviviq misuse or dependence. But if you’ve ever misused or developed mental dependence on drugs or alcohol, you may be at risk of Quviviq misuse and dependence. In this case, talk with your doctor about whether Quviviq is right for you.
Do not take more Quviviq than your doctor prescribes. Taking more than this can lead to serious side effects.
Symptoms of overdose
Symptoms caused by an overdose can include:
- muscle weakness
- sleep paralysis (being unable to move or talk for a few seconds or minutes as you’re falling asleep or waking up)
