Waklert 150 is a prescription drug that contains armodafinil and is used to treat narcolepsy, shift-work sleep disorder, and daytime sleepiness caused by sleep apnea. Regular daily dose under medical supervision is normal; it is not meant for "as-needed" use as a wakefulness enhancer in healthy individuals.
