Can modafinil replace sleep?

Modafinil is mostly used to treat sleep problems, such as narcolepsy, but it doesn’t take the place of sleep. It encourages vigilance and wakefulness, but it cannot replace sleep’s restorative qualities, which include memory consolidation, cell repair, and the restoration of general cognitive function. Modafinil usage for sleep deprivation over time can have detrimental repercussions for both physical and mental health, including mood swings and diminished cognitive function. While it could momentarily cover up weariness, it cannot replace the biological necessity of regular sleep for optimum health. Sleep continues to be essential for long-term health.
