Generic Nuvigil is currently FDA-approved to treat excessive daytime sleepiness associated with obstructive sleep apnea, narcolepsy, and shift work disorder. It is commonly used off-label to treat attention deficit hyperactivity disorder, chronic fatigue syndrome, and major depressive disorder.
Generic Nuvigil is approved by the U.S. FDA for the treatment of narcolepsy and shift work sleep disorder, and as an adjuvant therapy for obstructive sleep apnea. For narcolepsy and obstructive sleep apnea, armodafinil is taken as a once daily 150 mg. For shift work sleep disorder, 150 mg of Generic Nuvigil are taken one hour prior to starting work. Slow dose titration is needed to mitigate some side effects.
