Ramelteon
Generic: ramelteon · Brand: Rozerem® · Class: Hypnotic — Melatonin Receptor Agonist (Non-Controlled)
🧠
How It Works
Ramelteon is a melatonin receptor agonist — the first and only sleep medication in its class. It works by selectively activating MT1 and MT2 melatonin receptors in the suprachiasmatic nucleus (the brain's circadian clock), mimicking the action of natural melatonin to promote the transition to sleep. Unlike benzodiazepines and Z-drugs, it does not enhance GABA activity, does not cause dependence, has no abuse potential, and is not a controlled substance. It is specifically effective for sleep onset problems and circadian rhythm disruption. It is the safest prescription sleep medication available for long-term use.

Important Safety Information
Fluvoxamine Interaction: Fluvoxamine (Luvox) dramatically increases ramelteon levels by inhibiting its metabolism. This combination should be avoided — tell your provider if you take fluvoxamine.
Alcohol: Do not combine with alcohol — can increase sedative effects.
Liver Disease: Ramelteon is primarily metabolized by the liver. Use with caution in liver disease.
Hormonal Effects: Long-term use may rarely affect prolactin and testosterone levels. Discuss with your provider if you notice changes in libido, fertility, or menstrual cycle.
Pregnancy: Discuss risks and benefits with your provider.
