What Is Modafinil 200mg?
Modafinil is a wakefulness-promoting agent that affects certain neurotransmitters in the brain involved in alertness and cognitive function. Unlike stimulants such as amphetamines, Modafinil is considered milder in its mechanism and has a lower risk of dependence when used correctly.
Medical professionals generally prescribe Modafinil for:
-
Narcolepsy
-
Shift work sleep disorder
-
Daytime sleepiness due to sleep apnea
-
Excessive tiredness related to irregular sleep patterns
Although many people online talk about Modafinil as a “focus enhancer,” it is important to remember that its approved use is medical and requires proper guidance from a healthcare provider.

2. Shift Work Sleep Disorder (SWSD)
A condition affecting people who work night shifts or rotating shifts, leading to difficulty staying awake.
3. Obstructive Sleep Apnea (OSA)
