Uses of Waklert 150 mg Tablet

How Waklert 150 mg Tablet works

Armodafinil is a wakefulness-promoting agent that increases alertness by modulating neurotransmitters in the brain (including dopamine pathways via dopamine transporter inhibition) and other arousal systems. It helps reduce excessive sleepiness without being a traditional amphetamine stimulant.

Take exactly as prescribed. For narcolepsy/OSA: usually taken once daily in the morning. For SWSD: usually taken about 1 hour before the start of the work shift. Can be taken with or without food; swallow tablet whole with water. Avoid taking late in the day unless directed, as it may cause insomnia.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
