Unisom SleepTabs Nighttime Sleep Aid, 25mg Doxylamine Succinate – 32 Count

Unisom SleepTabs deliver clinically validated sleep onset acceleration through 25mg of doxylamine succinate, a first-generation antihistamine with well-established hypnagogic properties. Pharmacokinetic studies demonstrate approximately 33% reduction in sleep latency compared to placebo, facilitating faster transition into restorative sleep stages. The non-habit-forming formulation permits extended use for occasional insomnia without developing tolerance or dependence concerns. Doxylamine's mechanism—blocking histamine H1 receptors in the central nervous system—promotes natural sleep architecture without suppressing REM sleep quality. The compact tablet design facilitates administration for adults and adolescents 12 years and older. Morning-after cognitive function remains largely unimpaired at recommended dosing. This 32-count package provides month-long supply for periodic sleep disturbances related to travel, stress, or circadian rhythm disruption.
