Eszopiclone 3 mg, marketed as Lunesta, is a nonbenzodiazepine hypnotic prescribed for insomnia treatment by boosting GABA activity in the central nervous system. It is advised to be consumed right before bedtime as it might cause next-day drowsiness and complex sleep-related behaviors. Common side effects can include dizziness and dry mouth, with potential for dependence and withdrawal symptoms. This medication is metabolized by the liver and processed by the kidneys, so caution is recommended when taken with other central nervous system depressants.
