Quviviq vs. Hydroxyzine
See how Quviviq and Hydroxyzine compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Quviviq is FDA-approved specifically for insomnia, while hydroxyzine's use for sleep is off-label, borrowed from its antihistamine side effects.
Quviviq is a Schedule IV controlled substance costing roughly $520 to $685 a month, while generic hydroxyzine typically runs $10 to $40 a month.
Both drugs can cause next-day drowsiness, so caution with driving or operating machinery the morning after applies to either one.
Quviviq vs. Hydroxyzine Drug Summary
Quviviq
Quviviq (daridorexant) is a dual orexin receptor antagonist, a class of sleep medication that blocks brain chemicals that keep you awake. It is FDA-approved for adults with insomnia and comes as a 25 mg or 50 mg tablet taken once nightly, within 30 minutes of bedtime.
Hydroxyzine
Hydroxyzine is a first-generation antihistamine FDA-approved for anxiety, itching, and pre-procedure sedation, and it's sometimes used off-label for sleep because of its sedating effects. It's taken by mouth, with typical anxiety dosing of 50 mg to 100 mg four times a day.

Quviviq vs. Hydroxyzine Indications
Quviviq
Quviviq is FDA-approved to treat insomnia in adults who have trouble falling asleep, staying asleep, or both. It works by blocking orexin receptors in the brain that keep you awake, helping you fall asleep and stay asleep through the night.
Difficulty falling asleep
Difficulty staying asleep
Adults only (not studied in children)
Not for narcolepsy (contraindicated)
Hydroxyzine
Hydroxyzine is FDA-approved for short-term anxiety relief, itching from allergic skin conditions, and pre-procedure sedation. It is not approved for insomnia, though it's often prescribed off-label at bedtime because drowsiness is one of its most common side effects.
Anxiety and tension (short-term)
Itching from allergic skin conditions
Pre-procedure sedation
Off-label: trouble sleeping (not FDA-approved)
Quviviq vs. Hydroxyzine Pros and Cons
Quviviq
Quviviq is the newest FDA-approved insomnia medication, backed by trial data on both falling asleep and staying asleep. As a Schedule IV controlled substance without a generic option, it tends to cost more and may need insurance prior authorization.
Pros
FDA-approved specifically for insomnia, with trial data on falling and staying asleep
Once-nightly dosing with no titration schedule required
No signs of physical dependence or withdrawal seen in clinical trials
No dose adjustment needed for kidney (renal) impairment
Cons
Schedule IV controlled substance, subject to prescription monitoring
Contraindicated in narcolepsy and needs caution with other CNS depressants
No generic version yet; costs roughly $520 to $685 a month without insurance
Newer drug (approved 2022) with less long-term real-world data than older options
Hydroxyzine
Hydroxyzine is a decades-old antihistamine doctors sometimes prescribe off-label for sleep because drowsiness is one of its main side effects. It's inexpensive and widely available, but it lacks insomnia-specific trial data and carries more anticholinergic baggage.
Pros
Inexpensive generic, typically $10 to $40 a month without insurance
Decades of clinical use across anxiety, allergy, and sedation settings
Not a controlled substance, so no misuse classification or extra monitoring
Also treats itching and pre-procedure anxiety, useful for overlapping symptoms
Cons
Not FDA-approved for insomnia; sleep use is off-label
Anticholinergic effects like dry mouth and constipation, more pronounced in older adults
Carries a QT-prolongation warning on its label
Efficacy specifically for sleep hasn't been studied the way Quviviq's has
