One drug that is frequently prescribed to help adults and children with deficit hyperactivity disorder (ADHD) is Provigil 100 mg. Still, it is generally not recommended for children younger than six. This medication can significantly reduce hyperactivity and impulsivity in ADHD patients as well as help them focus more intently on their tasks. It is essential to take Provigil 100 mg every day to obtain the maximum benefit; ideally, do so at the same time every day to help with memory. As directed by the physician, take it orally two or three times a day; ideally, this should be done 30 to 45 minutes before meals.
