[Posted 05/15/2014] ISSUE: FDA has notified health professionals and their medical care organizations of a new warning that the insomnia drug eszopiclone (Lunesta) can cause next-day impairment of driving and other activities that require alertness. FDA recommends a decreased starting dose of eszopiclone to 1 mg at bedtime. Women and men are equally susceptible to impairment from eszopiclone, so the recommended starting dose of 1 mg is the same for both. FDA approved changes to the eszopiclone prescribing information and the patient Medication Guide to include these new recommendations. The drug labels for generic eszopiclone products will also be updated to include these changes.
BACKGROUND: A study of eszopiclone found that the previously recommended dose of 3 mg can cause impairment to driving skills, memory, and coordination that can last more than 11 hours after receiving an evening dose (see Data Summary). Despite these driving and other problems, patients were often unaware they were impaired. The new lower recommended starting dose of 1 mg at bedtime will result in less drug in the blood the next day.
RECOMMENDATION: Health care professionals should follow the new dosing recommendations when starting patients on eszopiclone. Patients should continue taking their prescribed dose of eszopiclone and contact their health care professionals to ask about the most appropriate dose for them. FDA is continuing to evaluate the risk of impaired mental alertness with the entire class of sleep aid drugs, including over-the-counter drugs available without a prescription, and will update the public as new information becomes available.

Eszopiclone is used to treat insomnia (difficulty falling asleep or staying asleep). Eszopiclone is in a class of medications called hypnotics. It works by slowing activity in the brain to allow sleep.
Eszopiclone comes as a tablet to take by mouth. It is usually taken once a day at bedtime or after unsuccessfully trying to fall asleep. Do not take eszopiclone with or shortly after a heavy, high-fat meal. Eszopiclone may not work well if it is taken with high fat foods. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take eszopiclone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
You will probably become very sleepy soon after you take eszopiclone and will remain sleepy for some time after you take the medication. You should only take eszopiclone immediately before you go to bed or after you have gone to bed and have been unable to fall asleep. Only take eszopiclone if you will be able to stay in bed for at least 8 hours after taking the medication. If you do not go to bed right after you take eszopiclone or if you get up too soon after taking eszopiclone, you may experience dizziness, lightheadedness, hallucinations (seeing things or hearing voices that do not exist), and problems with coordination and memory.
Your doctor may change your dose of eszopiclone during your treatment. Your doctor may increase your dose to help you sleep better or decrease your dose if you are too drowsy during the daytime.
You should be sleeping well within 7 to 10 days after you start taking eszopiclone. Call you doctor if your sleep problems do not improve during this time, if they get worse at any time during your treatment, or if you notice any changes in your thoughts or behavior.
Do not stop taking eszopiclone without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking eszopiclone you may experience withdrawal symptoms such as anxiety, unusual dreams, stomach and muscle cramps,nausea, vomiting, sweating, shakiness, and rarely, seizures.
After you stop taking eszopiclone, you may have more difficulty falling asleep and staying asleep than you did before you took the medication. These sleep problems are normal and usually get better without treatment after one or two nights.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with eszopiclone and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Eszopiclone should only be taken at bedtime. If you did not take eszopiclone before you went to bed and you are unable to fall asleep, you may take eszopiclone if you will be able to stay in bed for at least 8 hours afterward. Do not take a double dose of eszopiclone to make up for a missed dose.
