This medication is used to treat a certain sleep problem (insomnia). It may help you fall asleep faster, stay asleep longer, and lessen how often you wake up during the night, so you can get a better night's rest. Eszopiclone belongs to a class of drugs called sedative-hypnotics. It acts on your brain to produce a calming effect.

Use of this medication is usually limited to short treatment periods of 1 to 2 weeks or less. If your insomnia continues for a longer time, talk to your doctor to see if you need other treatment.

Read the Medication Guide provided by your pharmacist before you start using eszopiclone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once nightly just before you get into bed. Do not take it with or right after a high-fat or heavy meal since it may not work as well. The dosage is based on your medical condition, age, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

To reduce your risk of side effects, your doctor will direct you to start this medication at a low dose and gradually increase your dose if needed. Follow your doctor's instructions carefully. Do not take more of this medication than prescribed because your risk of side effects will increase.

(See also Precautions section.)

If you suddenly stop using this medication, you may have withdrawal symptoms (such as nausea, vomiting, flushing, stomach cramps, nervousness, shakiness). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used eszopiclone for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.
