Modafinil, commonly sold under the brand name Provigil, is a medication that is used to promote wakefulness in individuals with conditions such as narcolepsy, sleep apnea, and shift work sleep disorder. It is a prescription drug that is classified as a eugeroic, which means it is a wakefulness-promoting agent that does not have the same side effects as traditional stimulants.

Modafinil works by affecting certain neurotransmitters in the brain that are involved in regulating the sleep-wake cycle. It is believed to increase levels of dopamine in the brain, which can help improve alertness, focus, and cognitive function. Unlike other stimulant medications, Modafinil does not typically cause jitteriness, anxiety, or agitation.

Provigil is often prescribed to individuals who struggle with excessive daytime sleepiness or difficulty staying awake during normal waking hours. It is also sometimes used off-label to enhance cognitive function, improve memory, and increase productivity in healthy individuals.
