Lunesta is a fast-acting drug that is rapidly-absorbed in the body. This results in quick effects within an hour after taking it. The National Institutes of Health (NIH) recommends planning to go to sleep directly after taking the drug and expecting to stay asleep for at least seven to eight hours.

How soon before bed should I take Lunesta?

Take eszopiclone just before going to bed, when you are ready to go to sleep, or when you are having trouble falling asleep. This medicine works very quickly to put you to sleep. Do not take this medicine when your schedule does not permit you to get a full night's sleep (7 to 8 hours).

Is 3 mg of Lunesta a lot?

The total dose of Lunesta should not exceed 3 mg, once each evening immediately before bedtime. Elderly patients and patients with hepatic impairment should not be prescribed doses of more than 2 mg.
