Armodafinil is a medicine that is taken by mouth every morning to treat narcolepsy and obstructive sleep apnea. It is also given to people with shift work sleep problem. They take it once a day, an hour before their shift starts. You can take it with or without food, but it may take longer to work if you don't. If it is used to treat sleep apnea, keep using other treatments unless your doctor tells you to stop.

The right amount to give varies on the patient's health and how well they respond to treatment. If a person stops taking armodafinil all of a sudden, withdrawal signs may happen, and the doctor may slowly lower the amount. If a person has used armodafinil for a long time or in high amounts, withdrawal is more likely to happen. Talk to the doctor if the medicine stops working well. Buy Armodafinil can sometimes make people addicted, especially if they already have a problem with drugs. Follow the amount instructions to lower the chance of getting hooked. If the problem doesn't get better or gets worse, you should see a doctor.
