What is Modafinil?

Modafinil, also known as Provigil, is a medication used to treat sleepiness caused by narcolepsy, shift work sleep disorder, or obstructive sleep apnea. While it has been used off-label as a purported cognitive enhancer, the research on its efficacy for this purpose is inconclusive.

Modafinil Uses

Modafinil decreases sleepiness caused by narcolepsy and other sleep disorders, such as periods of no breathing while sleeping (obstructive sleep apnea). It is also used to help you stay awake during the workday if your work schedule prevents you from having a regular sleep routine (shift work sleep disorder). This medication does not treat sleep disorders and may not completely eliminate your sleepiness. It is not a substitute for getting enough sleep. It should not be used to treat tiredness or to keep people from sleeping if they do not have a sleep disorder. It's unclear how this works to keep you awake. It is thought to work by influencing certain brain chemicals.

How to use Modafinil

Before you begin using modafinil, and each time you get a refill, read the Medication Guide provided by your pharmacist. If you have any confusion regarding the dosage, consult your doctor or pharmacist.

Take this medication orally with or without food as directed by your doctor for narcolepsy, usually once daily in the morning. Alternatively, if directed by your doctor, the total daily dose of this may be divided into morning and noon dose.

Take this medication orally with or without food as directed by your doctor for obstructive sleep apnea, usually once daily in the morning. Continue with other treatments (such as the CPAP machine or mouth device) unless your doctor instructs you to discontinue them.

For a sleep disorder, take it orally, with or without food, as directed by your doctor, usually once a day, 1 hour before your work shift begins.

The dosage is dependent on your medical condition as well as your response to treatment. To get the advantage of this medication, take it on a regular basis.

If you stop taking this medication abruptly, you may experience withdrawal in symptoms (such as shaking, sweating, chills, nausea, vomiting, confusion). To prevent symptoms of withdrawal, your doctor might gradually decrease your dose. Withdrawal is more likely if you have used this medicine for an extended period of time or in high doses.

When this medication is used for an extended period of time, it may lose its effectiveness. Consult your doctor if this medication is no longer working properly.

Despite the fact that it benefits many people, this medication can sometimes lead to addiction. If you have a substance use disorder (such as overuse or addiction to drugs/alcohol), your risk may be increased.
