- Lunesta is a hypnotic drug, one that is designed to help regulate a chemical imbalance in the brain that can cause insomnia. It works by inducing a relaxed state which helps the patient to fall asleep and remain asleep for an extended period of time. Because Lunesta induces drowsiness, patients must ensure they will not need to drive or operate machinery for at least 8 hours after taking Lunesta.
- Common side effects reported after taking Lunesta include dry mouth, headache, dizziness, difficulty remaining alert the following morning, bad aftertaste and feeling like you have a cold. Some people have reported memory loss, feelings of anxiety, confusion and abnormal thoughts or behavior. In patients with a history of depression Lunesta may cause a worsening of this condition, including suicidal urges.
- Some patients may be allergic to one or more of the ingredients in Lunesta. Allergic reactions may include nausea, vomiting, swelling of the throat and tongue and difficulty breathing.
- Lunesta should not be used by patients with a history of mental illness or depression. Patients with liver disease should not use this sedative, nor should people with a history of drug or alcohol abuse. Women who are pregnant, nursing, or may become pregnant should not use Lunesta.
- Although Lunesta is non-narcotic, it may still be habit-forming. Patients who stop taking Lunesta abruptly may experience withdrawal. Patients should discuss the decision to stop using Lunesta with their doctor. A gradual reduction of the dosage will help prevent withdrawal symptoms.
