Product Information


Modvigil contains 200mg of Modafinil as the active ingredient. Modafinil belongs to a class of drugs called wakefulness promoting agents. This drug helps patients stay awake by reducing excessive sleepiness due to narcolepsy and other sleep problems. It is also used with other treatments to prevent excessive sleepiness caused by obstructive sleep apnea or hypopnea syndrome. Modvigil also helps people with shift work disorder to stay awake during working hours of those with graveyard or rotating shifts.  The exact mechanism of Modafinil is unknown, but is thought to change levels of neurotransmitters in the part of the brain responsible for controlling sleep and wake cycle. It is thought to increase brain activity in parts involved in alertness and raise dopamine levels.
