Does modafinil improve sleep quality?

Modalert is given for narcolepsy and sleep apnea. The goal is awake and alertness, not sleep quality. Modafinil alters brain chemicals to keep people alert. For people with sleep difficulties, modafinil may disturb sleep patterns or cause insomnia if taken too close to bedtime. Modalert must be used as prescribed to avoid sleep disruption. Other therapies and lifestyle adjustments are advised to improve sleep.
