Ambien vs. Lunesta
See how Ambien and Lunesta compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Ambien and Lunesta are both Schedule IV non-benzodiazepine hypnotics prescribed for insomnia, though their FDA labels differ slightly on duration of use.
Ambien comes in just two doses, 5 mg or 10 mg nightly, while Lunesta offers three strengths from 1 mg to 3 mg for finer dose adjustment.
Ambien's most common side effect is dizziness, while Lunesta's signature complaint is an unpleasant taste that lingers into the next day.
Ambien vs. Lunesta Drug Summary
Ambien
Ambien (zolpidem) is a non-benzodiazepine sedative-hypnotic that treats short-term insomnia by acting on GABA-A receptors in the brain. It is an immediate-release tablet taken once nightly on an empty stomach, at a dose of 5 mg or 10 mg. It has been on the market since 1992 and is not intended for long-term nightly use.
Lunesta
Lunesta (eszopiclone) is a nonbenzodiazepine hypnotic approved to treat insomnia, also working through GABA-A receptor activity. It is taken once nightly as a tablet, with doses ranging from 1 mg to 3 mg depending on response and tolerability. Approved in 2004, its label does not carry the same short-term-only restriction as Ambien's.

Ambien vs. Lunesta Indications
Ambien
Ambien is FDA-approved for short-term treatment of insomnia in adults who have trouble falling asleep. It is not approved for chronic nightly use or for use in children. Doctors typically start women at a lower dose than men because women clear the drug more slowly.
Short-term insomnia with difficulty falling asleep
Not approved for long-term nightly use
Not approved for children
Lower starting dose recommended for women
Lunesta
Lunesta is FDA-approved to treat insomnia in adults, without the short-term-only limitation stated on Ambien's label. It is not approved for use in children. Elderly patients and those taking certain other medications need a reduced dose.
Treatment of insomnia in adults
Not approved for pediatric use
Reduced dose required in elderly patients
Dose adjustment needed with CYP3A4 inhibitors
Ambien vs. Lunesta Pros and Cons
Ambien
Ambien has decades of clinical use, low generic cost, and dosing tailored by sex to reduce next-day impairment. It carries the same complex-sleep-behavior and dependence warnings as other Z-drugs, and the 10 mg dose brings a stronger next-day driving impairment risk. Insurance coverage for generic zolpidem is usually straightforward given its low cost.
Pros
Generic zolpidem costs roughly $15 to $90 per month
Longer track record with more real-world safety data
Sex-specific dosing lowers next-day impairment risk
Cons
Higher risk of next-day driving impairment at 10 mg
Not approved for long-term nightly use
Elderly and liver-impaired patients limited to 5 mg dose
Lunesta
Lunesta offers more dosing flexibility with three strengths, and its label does not restrict use to short-term treatment the way Ambien's does. Its main tradeoff is a distinctive bad taste many patients notice the morning after, and brand-name pricing is far higher than generic zolpidem. Generic eszopiclone narrows some of that cost gap.
Pros
Three dose strengths allow finer titration
Label does not limit use to short-term treatment
Generic eszopiclone available at lower cost than brand
Cons
Brand list price runs roughly $1,300 to $1,600 per month
Unpleasant taste affects up to 26% of patients
Dose reduction needed with certain other medications
