Although there are several FDA-approved medications for use in narcolepsy, there are no FDA-approved medicines for idiopathic hypersomnia. Therefore, the wake-promoting medications used in narcolepsy are also commonly used off-label to help manage the excessive daytime sleepiness of idiopathic hypersomnia. "These treatments have not been studied to nearly the same extent in patients with idiopathic hypersomnia, and some patients with idiopathic hypersomnia do not achieve adequate control of symptoms with these medications."[5]
