Modafinil, commonly known by its brand name Provigil, is a prescription medication primarily used to treat narcolepsy, sleep apnea, and shift work sleep disorder. This wakefulness-promoting agent is increasingly popular for enhancing cognitive function and combating fatigue. Understanding the appropriate dosage of Modafinil is crucial for maximizing its benefits while minimizing potential side effects.

- Shift Work Sleep Disorder: A dose of 200 mg is recommended approximately one hour before the start of the work shift.
- Maximum Daily Dose: The total daily dose should not exceed 400 mg, as higher doses could lead to adverse effects.
2. Factors Influencing Modafinil Dosage
Several individual factors can affect the appropriate dosage of Modafinil:
