Modafinil is a wakefulness-promoting medication, and it is used to treat sleep disorders such as narcolepsy, sleep apnea, and shift work sleep disorder. It helps enhance alertness, focus, and cognitive performance without the jittery side effects associated with traditional stimulants. Often referred to as a “smart medication,” modafinil is also used off-label to enhance productivity and concentration. Despite its benefits, users should be cautious of potential side effects and consult a doctor before use. To have more details about Modafinil, visit the website of Health Matter.
