Modafinil is a wakefulness-promoting medication primarily used to treat narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD). It works by stimulating certain chemicals in the brain to promote alertness and reduce excessive daytime sleepiness. Modafinil is also sometimes used off-label as a cognitive enhancer or to improve focus and attention in individuals with attention-deficit/hyperactivity disorder (ADHD) or other cognitive conditions.
