Provigil is the brand name for modafinil, a prescription medication primarily used to improve wakefulness in people with certain sleep disorders. It is approved to treat excessive daytime sleepiness associated with conditions such as narcolepsy, obstructive sleep apnea (when used alongside appropriate treatment), and shift work sleep disorder.
Provigil works by affecting chemicals in the brain that regulate the sleep-wake cycle. Although its exact mechanism of action is not fully understood, it is considered a wakefulness-promoting medication rather than a traditional stimulant.
Common Medical Uses
Healthcare providers may prescribe Provigil for the following approved conditions:
Narcolepsy
Obstructive sleep apnea with persistent daytime sleepiness
Shift work sleep disorder
In some cases, healthcare professionals may prescribe modafinil for other medical purposes based on their clinical judgment. Patients should always use the medication only as directed by their healthcare provider.

Provigil is available as an oral tablet. The dosage and timing depend on the condition being treated and the patient's medical history.
