The half-life of Modalert 200mg (modafinil) is usually 12 to 15 hours, which means it takes the body approximately that long to get rid of half of the medication. Modafinil’s effects usually subside 12 to 15 hours after use, however this might vary depending on a person’s metabolism, dose, and general health. The energizing effects, which include heightened alertness and decreased weariness, often persist for eight to twelve hours. After this period of time, you’ll probably notice a drop in attention or begin to feel more exhausted. Modafinil should not be taken too late in the day in order to prevent disrupting sleep. Regarding dose and time, always heed your doctor’s advice.
