The medication Artvigil 150 mg, which contains armodafinil, acts for a long time and usually remains in the body for 12 to 14 hours. The benefits often peak two hours after use, and the majority of the day is marked by a considerable increase in focus and alertness. It takes around 12 to 15 hours for half of the dose of armodafinil to be removed from the body, which is known as its half-life. Consequently, Artvigil 150 traces may last in your body for as long as 24 to 36 hours. To prevent sleep disruptions at night, it is best taken in the morning.
