Modafil MD is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts).

Modafil MD is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sleep and therefore doesn't get enough restful sleep). Modafil MD is in a class of medications called wakefulness promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.

Modafil MD works on multiple brain processes at the same time in order to produce its unique, clean sense of stimulation. Scientists think it affects the Noradrenaline neurotransmitters, Glutamate, Histaline and GABA. It results in the natural sense of being awake and alert. Other beneficial effects include increased motivation, which leads to slight mood elevation, increased productivity and an overall enhanced ability to focus on important matters.

Side effects: blurred vision, indigestion, nausea, hair fall, headache, abdominal pain.
