ARMOGARD 250mg, containing the active ingredient Armodafinil, is used to improve wakefulness in adult patients with excessive daytime sleepiness (EDS) caused by narcolepsy, obstructive sleep apnea (OSA) (also known as hypopnea syndrome), or shift work disorder (SWD). It does not cure these conditions but helps patients stay awake during the day and maintain a normal sleep-wake cycle.
