Nuvigil (Modafinil): A Great Medication to Combat Fatigue, But Be Careful

Table of Contents

From NUVIGIL is a prescription medicine used to improve wakefulness in adults who experience excessive sleepiness (ES) due to one of the following diagnosed sleep disorders:

Obstructive sleep apnea (OSA)

In patients with OSA, NUVIGIL is used along with other medical treatments for this sleep disorder. NUVIGIL is not a replacement for your current treatment. Consult your doctor about the importance of continuing your current OSA treatment while taking NUVIGIL Shift work disorder (SWD)


You should be diagnosed with one of these sleep disorders before taking NUVIGIL. Sleepiness can be a symptom of other medical conditions that need to be treated. NUVIGIL will not treat the sleep disorders mentioned above. NUVIGIL may help with the sleepiness caused by these conditions, but it may not stop all of your sleepiness. NUVIGIL does not take the place of getting enough sleep. Follow your doctor’s advice about good sleep habits and using other treatments.


Armodafinil (brand name Nuvigil) is used to treat excessive sleepiness caused by narcolepsy (a condition of excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Armodafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome. Armodafinil is in a class of medications called wakefulness-promoting agents. It works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness. Some insurance companies do not want to pay for it. It is not an amphetamine and it does not require a special prescription since it not a class III DEA regulated drug. Many doctors have samples so that you can try it before you commit to using it. I got too anxious when I took a full dose. A quarter of a tablet (it contains 150 mg) worked fine for me only once or twice a day to keep me going if I had to work after a bad night sleep. A one month supply can last a long time if taken as needed and at a reduced dose. I did not take it after 3 pm since my sleep would be impaired.
