A single Waklert 150mg pill of armodafinil usually lasts 12 to 15 hours, depending on the sensitivity and metabolism of the individual. It provides prolonged wakefulness and mental alertness throughout the day because of its greater half-life compared to modafinil. Its effects usually start to manifest 1 to 2 hours after administration, and they peak 6 to 8 hours later. For this reason, it can be used to treat drowsiness throughout the day in people with narcolepsy or shift work disorder. Waklert works, however if taken too late in the day, it might have negative consequences including sleeplessness.
