It is indicated for several sleep‑related conditions: - Insomnia: assists adults in initiating and maintaining sleep. - Circadian rhythm sleep disorder: helps align the internal clock with the desired sleep schedule. - Jet lag: reduces the time needed to adjust to new time zones after rapid travel.
