Rozerem product identity in Japan
Use this table to avoid confusing Rozerem with other Japanese insomnia medicines. It is a product-identification guide, not a medical recommendation.

|---|---|---|
| Brand name | ロゼレム錠 / Rozerem Tablets | Confirm the exact Japanese product name from package or listing. |
| Ingredient | ラメルテオン / Ramelteon | Confirm it is ramelteon, not an orexin receptor antagonist or Z-drug sleep medicine. |
| Common package dose amounts | 8 mg | Confirm amount printed on package and tablet count. |
| Class | Melatonin receptor agonist | Compare separately from Z-drug or benzodiazepine sleep medicines. |
| Japan information holder | Manufactured by MSD; sales and information activities transferred to Daiichi Sankyo in Japan | Use current Japanese product source and package evidence when possible. |
Review points before support
Confirm the medicine class
Rozerem is a melatonin receptor agonist. It should be separated from Dayvigo, Quviviq, Belsomra, Vorzzz, and Lunesta when comparing product identity.
Check interaction context
Japanese materials flag strong CYP3A inhibitor concerns. Support should ask about current medicines when reviewing a sleep-medicine request.
Check next-day safety context
Sleep medicines can involve next-day drowsiness, impaired alertness, abnormal sleep behavior, and safety-sensitive work concerns.
Rozerem should not be treated as a simple product-name lookup. Sleep-medicine requests should include current-medicine context, interaction context, destination country, and quantity. This page does not diagnose insomnia or choose a dose.
