Excessive daytime sleepiness can make it difficult to remain alert during important daily activities. It may be associated with narcolepsy, obstructive sleep apnea, or shift work disorder. Waklert 150 mg contains armodafinil, a wakefulness-promoting medicine used for these conditions. Identifying the underlying sleep problem is important rather than treating tiredness as a normal issue. Medical guidance can help determine whether armodafinil is appropriate for an individual.
