Artvigil 150mg contains armodafinil and is primarily prescribed to promote wakefulness in conditions such as narcolepsy, obstructive sleep apnea, and shift work sleep disorder. It is not generally approved as a primary treatment for depression. Some research has explored wakefulness-promoting medicines as an add-on treatment for certain patients with depression, particularly when fatigue or excessive sleepiness remains despite antidepressant treatment, but this should only be considered under medical supervision.
