Brand name:

Provigil

Generic name: Modafinil

Why is Provigil prescribed?

Provigil is a stimulant drug used to treat unusually sleepy people who have been diagnosed with narcolepsy, obstructive sleep apnea/hypopnea syndrome, or shift work sleep disorder. You should be diagnosed with one of these sleep disorders before taking Provigil, since sleepiness can be a symptom of other medical conditions.

Most important fact about Provigil

Provigil will not cure any sleep disorder; it merely treats the symptom of sleepiness. This medication should not be used in place of getting enough sleep. You should follow your doctor's advice about maintaining good sleep habits.

Provigil, like other stimulants, has the potential for abuse. It can alter your mood, perception, thinking, and feelings, providing an artificial "lift" and potentially leading to a certain degree of dependence (although discontinuation of the drug does not produce physical withdrawal symptoms). Make a point of taking only the prescribed dose: Never increase the dose or take additional doses.

How should you take Provigil?

Food does not reduce the effectiveness of this medication. However, it will delay the onset of action by approximately 1 hour.

• If you miss a dose...
  Take it as soon as possible. If you don't remember until the next day, skip the dose you missed and go back to your regular schedule. Do not take a double dose.

• Storage instructions...
  Store at room temperature.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Provigil.

  Anxiety, depression, diarrhea, difficulty sleeping, dizziness, dry mouth, headache, infection, loss of appetite, loss of muscle strength, lung problems, nausea, nervousness, prickling or tingling feeling, runny nose, sore throat
