Dayvigo
Dayvigo (lemborexant) is a dual orexin receptor antagonist FDA-approved to treat insomnia in adults who have trouble falling asleep, staying asleep, or both. It comes as a 5 mg or 10 mg tablet taken once nightly, right before bed.
Hydroxyzine

Dayvigo vs. Hydroxyzine Indications
Dayvigo
Dayvigo is FDA-approved specifically for insomnia in adults, covering both trouble falling asleep and trouble staying asleep. It works by blocking orexin receptors that promote wakefulness, rather than boosting a calming brain chemical the way older sleep medicines do.
Difficulty falling asleep (sleep onset insomnia)
Difficulty staying asleep (sleep maintenance insomnia)
Approved for adults only, not children
Not approved for narcolepsy
Hydroxyzine
Hydroxyzine's FDA-approved uses are short-term relief of anxiety and tension, and control of itching from allergic skin conditions like hives or eczema. Doctors sometimes prescribe it off-label at bedtime for occasional insomnia, but this use isn't FDA-approved and hasn't been studied in dedicated insomnia trials.
Anxiety and tension linked to psychoneurosis (FDA-approved)
Itching from hives, eczema, or contact dermatitis (FDA-approved)
Sedation before or after surgery (FDA-approved)
Occasional sleeplessness (off-label, not FDA-approved)
Dayvigo vs. Hydroxyzine Pros and Cons
Dayvigo
Dayvigo targets the specific brain pathway that keeps you awake, and its 12-month trial data show effects hold up without rebound insomnia when stopped. As a newer brand-name drug with no generic yet, it typically costs more out of pocket and is classified as a controlled substance.
Pros
Purpose-built and FDA-approved for chronic insomnia
12-month trial data show sustained effect without rebound insomnia
One tablet at bedtime, no daytime dosing needed
Non-GABA mechanism avoids anticholinergic side effects like dry mouth
Cons
Roughly $135 to $400 per month without insurance, no generic yet
Schedule IV controlled substance with dependence potential
Can cause complex sleep behaviors like sleepwalking or sleep-driving
Fewer years of real-world use than decades-old hydroxyzine
Hydroxyzine
Hydroxyzine has decades of use as a low-cost, non-addictive option, but it was never studied specifically as a sleep drug and its anxiety dosing calls for up to four doses a day. Its strong antihistamine effects mean more next-day grogginess and dry mouth for some people.
Pros
Roughly $10 to $40 per month without insurance, generic only
Not a controlled substance, no known abuse potential
Decades of clinical use across anxiety and allergy conditions
Also relieves itching if allergy symptoms overlap with sleep issues
Cons
Not FDA-approved for insomnia; sleep use is off-label
Approved anxiety dosing requires up to four doses a day
Strong anticholinergic effects like dry mouth and weight gain
No dedicated insomnia trials backing its sleep effectiveness
