How Does It Work?

Rozerem works by stimulating melatonin receptors in the body. This helps people to fall asleep. Unlike many other insomnia medications, it is not habit-forming and is not a controlled substance.


The medication has been evaluated in several clinical studies for insomnia. In studies of Rozerem for chronic insomnia, people who took it fell asleep faster than people who did not take it. Similar results were seen in a study in people with transient insomnia (insomnia that comes and goes).
Studies have shown that it does not cause a "hangover" effect in the morning and does not cause rebound insomnia (worsening of insomnia after stopping a medication).
