Shift Work Sleep Disorder (SWSD) arises when irregular work hours, such as night shifts or rotating shifts, disturb the circadian rhythm. This may cause insomnia, tiredness, and concentration issues. Modalert 200 (modafinil) stimulates brain chemicals that increase alertness, treating SWSD. It may help SWSD patients remain alert and attentive throughout shifts by reducing daytime drowsiness.
