Staying awake and alert during the day is an important part of maintaining a normal routine. While occasional tiredness can happen after a busy day or an inadequate night's sleep, persistent excessive daytime sleepiness can sometimes be related to an underlying sleep disorder. Sleep apnea, narcolepsy, shift work, and other sleep-related conditions can all affect normal alertness.

When excessive sleepiness is associated with certain diagnosed conditions, healthcare professionals may prescribe medicines designed to promote wakefulness. Modafinil is one such prescription medicine and is used in adults with excessive sleepiness associated with narcolepsy, obstructive sleep apnea, or shift work disorder.

One product associated with the 200mg strength is Modafresh 200mg. Understanding modafinil, the meaning of its 200mg strength, its medical uses, and responsible-use considerations can help provide a clearer picture before considering this type of treatment.
