Lunesta is the brand name for eszopiclone, a sleep-aid approved by the FDA in 2004. Eszopiclone is available with a prescription under the brand name Lunesta. Eszopiclone is a non-benzodiazepine hypnotic of the cyclopyrrones family. Here's how eszopiclone is believed to work: GABA is an inhibitory neurotransmitter found in the brain. When eszopiclone enters the brain, it binds to a site on the GABA receptor, increasing inhibition and creating a powerful sedative effect, which induces sleep. Eszopiclone is used to treat insomnia. It is currently the only sleep-aid that works safely and effectively for longer periods of time, up to six months. Lunesta is taken orally and is available in one, two and three milligram tablets.This medication should be taken immediately before bed to induce rapid onset of sleep. Because eszopiclone can be addictive, it is important not to take extra doses. The most common side effects of eszopiclone include drowsiness, dizziness and poor motor coordination, but you should ask your doctor for a complete list.Also, be sure to tell your physician immediately if you experience signs of allergic reaction like facial swelling, difficulty breathing, seizures or any other changes. Eszopiclone should be avoided by pregnant women and should not be taken in conjunction with alcohol or drugs that cause drowsiness. Ask your doctor for a full list of medications and conditions that should not be combined with eszopiclone. Lunesta can be helpful for patients who have chronic difficulty sleeping.
