How should I take modafinil?

Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Modafinil is usually given for 12 weeks or less. Follow the directions on your prescription label.

This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Modafinil is usually taken each morning to prevent daytime sleepiness, or 1 hour before the start of a work shift to treat work-time sleep disorders.

If you are taking modafinil to treat sleepiness caused by obstructive sleep apnea, you may also be treated with a continuous positive airway pressure (CPAP) machine. This machine is an air pump connected to a mask that gently blows pressurized air into your nose while you sleep. The pump does not breathe for you, but the gentle force of air helps keep your airway open to prevent obstruction.

Do not stop using your CPAP machine during sleep unless your doctor tells you to. The combination of treatment with CPAP and modafinil may be necessary to best treat your condition.

Modafinil will not cure obstructive sleep apnea or treat its underlying causes. Follow your doctor's instructions about all your other treatments for this disorder.

Talk with your doctor if you continue to have excessive sleepiness even while taking modafinil.

Taking this medication does not take the place of getting enough sleep.

Store at room temperature away from moisture and heat.

Take the missed dose as soon as you remember, but avoid taking the medication if you do not plan to be awake for several hours. If it is close to your normal bedtime hour, you may need to skip the missed dose and wait until the next day to take the medicine again.

Talk with your doctor about what to do if you miss a dose of modafinil. Do not take extra medicine to make up the missed dose.
