Provigil Dosage: An Introduction

The dose of Provigil® (modafinil) that your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • Your age
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

A lower Provigil dose (usually 100 mg a day) may be recommended for elderly people, people with certain medical conditions (such as liver disease), or people who take certain medications (see Provigil Drug Interactions).
