What is Modvigil?

Modvigil is the brand name for Modafinil, a prescription medication that promotes wakefulness and alertness. It is primarily used to treat excessive sleepiness caused by conditions such as narcolepsy, obstructive sleep apnea (OSA), and shift work sleep disorder (SWSD).

Modvigil works by altering the natural chemicals (neurotransmitters) in the brain that regulate the sleep–wake cycle, helping you stay awake, focused, and alert throughout the day.

Uses of Modvigil

Doctors typically prescribe Modvigil for:

• Narcolepsy (a condition causing uncontrollable daytime sleepiness)

• Obstructive Sleep Apnea (OSA), to reduce excessive sleepiness despite CPAP therapy

• Shift Work Sleep Disorder (SWSD), to help night-shift or rotating-shift workers stay alert

• Off-label: Sometimes used (under medical supervision) for focus, concentration, or fatigue management

👉 Important: Modvigil is not a substitute for adequate sleep. It should be used as part of a complete treatment plan, which may include lifestyle changes, sleep hygiene, and medical supervision.

Typical Adult Dose:

• Narcolepsy / OSA: 200 mg once daily in the morning

How Does Modvigil Work?

Modvigil (Modafinil) is a central nervous system (CNS) stimulant that promotes wakefulness.

It works by increasing the levels of certain neurotransmitters—such as dopamine, norepinephrine, and histamine—which help enhance alertness and reduce fatigue.

Unlike traditional stimulants, Modvigil provides a smooth, sustained increase in focus without the jittery feeling or energy crash.
