Insomnia Home > Lunesta

Lunesta is a sleep medicine that is commonly prescribed for the treatment of insomnia in adults. The medication is available in three different strengths. While Lunesta has proven to be effective in helping people fall asleep faster and stay asleep longer, it should be taken with caution because it is a controlled substance that can be abused. Headache, drowsiness, and unpleasant taste are some of the more common side effects of this drug.

How Does It Work?

Lunesta is part of a class of medications called sedative/hypnotics, which are known more commonly as sleep medicines. Like many other sleep medications, it is a controlled substance and may be abused.

Lunesta Effects

The drug has been evaluated in several clinical studies for insomnia. In studies for chronic insomnia, people who took it fell asleep faster and stayed asleep longer than people who did not take Lunesta. Similar results were seen in a study in people with transient insomnia (insomnia that comes and goes).
Also, studies have shown that the medication can cause mild rebound insomnia (worsening of insomnia after stopping a medication). Rebound insomnia symptoms usually occurred for only one night after the drug was stopped, after which people returned to their normal sleeping patterns.
