Armodafinil Tablet: Uses, Dosage, Side Effects, Precautions and Alternates product

Quick overview

Armodafinil Tablet, sold under the brand name Nuvigil, is a prescription CNS stimulant that promotes wakefulness. It is used for narcolepsy, obstructive sleep apnea, and shift work disorder, but it is not a cure for these sleep disorders. It works by changing levels of certain natural brain chemicals involved in controlling sleep and wakefulness.

What is Armodafinil Tablet

Armodafinil is a prescription medicine that promotes wakefulness. It is sold under the brand name Nuvigil and is not a cure for sleep disorders.

Armodafinil Tablet uses

  • Narcolepsy, a condition that causes overwhelming daytime sleepiness
  • Obstructive Sleep Apnea (OSA), used along with treatments like a CPAP machine
  • Shift Work Disorder (SWD), sleepiness caused by a work schedule that disrupts normal sleep

Benefits of Armodafinil Tablet

  • Helps maintain wakefulness and focus throughout the day or during a work shift
  • Contains the part of modafinil designed to give a longer-lasting wake-promoting effect

How Armodafinil Tablet works

Armodafinil changes the levels of certain natural brain chemicals in the area of the brain that controls sleep and wakefulness, though exactly how it works for sleep disorders isn't fully known.

Armodafinil Tablet dosage

Armodafinil is usually taken once a day. For narcolepsy or OSA, it is usually taken each morning. For shift work disorder, it is usually taken about one hour before the start of the work shift. It can be taken with or without food. Take it at the same time each day, and do not change the time without talking to your doctor. If taken too close to bedtime, it may be harder to fall asleep.

Continue using your CPAP machine or other prescribed treatments, since this medicine does not replace them. Keep taking it even if you feel well-rested, and do not stop without talking to your doctor. It is not approved for use in children.
