Armodafinil comes as a tablet to take by mouth. It is usually taken once a day. If you are taking armodafinil to treat narcolepsy or OSAHS, you will probably take it in the morning. If you are taking armodafinil to treat shift work sleep disorder, you will probably take it 1 hour before the start of your shift. Take armodafinil at around the same time every day. Do not change the time of day that you take armodafinil without talking to your doctor. Talk to your doctor if your work shift does not begin at the same time every day. Follow the directions on your prescription label carefully, and ask our doctor or pharmacist to explain any part you do not understand. Take armodafinil exactly as directed.

Armodafinil may be habit forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.

Armodafinil may decrease your sleepiness, but it will not cure your sleep disorder. Continue to take armodafinil even if you feel well-rested. Do not stop taking armodafinil without talking to your doctor.

Armodafinil should not be used in place of getting enough sleep. Follow your doctor's advice about good sleep habits. Continue to use any breathing devices or other treatments that your doctor has prescribed to treat your condition, especially if you have OSAHS.
