Lunesta vs. Hydroxyzine

See how Lunesta and Hydroxyzine compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Lunesta is FDA-approved specifically for insomnia, while hydroxyzine is approved for anxiety and itching and is only used for sleep off-label.

  • Both drugs can cause drowsiness and dry mouth, but Lunesta's signature side effect is an unpleasant taste while hydroxyzine's is weight gain.

  • Lunesta is a Schedule IV controlled substance with a boxed warning for complex sleep behaviors, while hydroxyzine carries no such controlled-substance restrictions.

Lunesta vs. Hydroxyzine Drug Summary

Lunesta

Lunesta (eszopiclone) is a nonbenzodiazepine sedative-hypnotic FDA-approved to treat insomnia in adults. It is taken as a single tablet by mouth right before bed, in 1 mg, 2 mg, or 3 mg strengths depending on response and other medications. It is a Schedule IV controlled substance due to its potential for dependence.

Hydroxyzine

Hydroxyzine is a first-generation antihistamine FDA-approved for short-term anxiety, itching from allergic skin conditions, and sedation before procedures. It is usually taken as an oral tablet, dosed at 50 to 100 mg up to four times a day for anxiety. It is sometimes used off-label at bedtime for sleep, which is not an FDA-approved use.

Lunesta vs. Hydroxyzine Indications

Lunesta

Lunesta is FDA-approved to treat insomnia in adults, helping people fall asleep faster and, at higher doses, stay asleep through the night. It is taken as one tablet right before getting into bed, only when a full night of sleep is possible. It is not approved for use in children.

  • Difficulty falling asleep

  • Difficulty staying asleep

  • For adults only, not children

  • Schedule IV controlled substance

Hydroxyzine

Hydroxyzine is FDA-approved for short-term relief of anxiety and tension, itching from allergic skin conditions, and sedation before or after medical procedures. It is not approved to treat insomnia, though its sedating effect leads some doctors to prescribe it off-label for occasional sleep trouble. Long-term anxiety use beyond four months has not been formally studied.

  • Short-term anxiety and tension

  • Itching from allergic skin conditions

  • Sedation before medical procedures

  • Off-label: occasional sleep trouble

Lunesta vs. Hydroxyzine Pros and Cons

Lunesta

Lunesta is purpose-built for insomnia, with dosing designed around a single nightly tablet rather than a schedule borrowed from another use. Like other sedative hypnotics, it carries a boxed warning for complex sleep behaviors such as sleepwalking or sleep-driving. Insurers often prefer the generic form, since brand pricing runs high.

Pros

  • FDA-approved specifically for insomnia, not off-label use

  • Only one dose needed at bedtime, no daytime dosing

  • Three strengths (1, 2, 3 mg) allow dose adjustment

  • Generic eszopiclone available at a fraction of brand cost

Cons

  • Schedule IV controlled substance with dependence potential

  • Boxed warning for complex sleep behaviors like sleepwalking

  • Unpleasant taste affects up to a quarter of users

  • Brand-name list price runs roughly $1,300 to $1,600 a month without insurance

Hydroxyzine

Hydroxyzine is not FDA-approved for sleep, so using it as a sleep aid relies on off-label judgment rather than insomnia-specific trial data. It is not a controlled substance, which means no special prescribing restrictions. Its anticholinergic effects, like dry mouth and weight gain, are more prominent than with hypnotics built specifically for sleep.

Pros

  • Not a controlled substance, no dependence monitoring required

  • Low-cost generic, commonly $10 to $40 a month without insurance

  • Also treats anxiety and itching, useful for overlapping conditions

  • No boxed warning for complex sleep behaviors

Cons

  • Not FDA-approved for insomnia; sleep use is off-label

  • Anticholinergic effects like dry mouth and weight gain are common

  • FDA dosing is four times daily, not designed for one nightly dose

  • Anxiety use beyond four months has not been formally studied
