Nuvigil – Everything You Need to Know

What is Nuvigil?

Nuvigil (armodafinil) is a wakefulness-promoting agent used to treat excessive sleepiness caused by narcolepsy, obstructive sleep apnea, and shift work sleep disorder. Nuvigil is available as a generic drug. Armodafinil may also be used for purposes not listed in this medication guide. There are no quick fixes for these sleep problems with Nuvigil. You will likely need to take this medication for several weeks before noticing the full effects.

Nuvigil is a central nervous system (CNS) stimulant. It works by promoting wakefulness and reducing the desire to sleep.

Nuvigil is not for use in treating tiredness or drowsiness that is not caused by a sleep disorder.

Nuvigil may be habit-forming and should be used only by the prescribed person.

Nuvigil should never be given to another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Nuvigil is available as an oral tablet. Nuvigil is usually taken once a day. Follow all directions on your prescription label. Never take this medicine in larger or smaller amounts or longer than recommended.

How does Nuvigil Work?

Nuvigil works by inhibiting the reuptake of dopamine, a neurotransmitter associated with wakefulness and alertness. Armodafinil also has a weak inhibitory effect on the norepinephrine and serotonin transporters. The exact mechanism of action of armodafinil is unknown.

Nuvigil Uses

Nuvigil treats excessive sleepiness caused by narcolepsy, shift work sleep disorder, and sleep apnea.

Narcolepsy is a condition that causes you to fall asleep suddenly and unexpectedly.

Shift work sleep disorder is a condition that causes you to have trouble sleeping when you are working odd hours or rotating shifts.

Sleep apnea is when you stop breathing for short periods during sleep.

Nuvigil may also be used for purposes not listed in this medication guide.

What are the possible side effects of armodafinil (Nuvigil)?

Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Stop taking armodafinil and call your doctor at once if you have:

  • Headache with chest pain and severe dizziness
  • Fainting
  • Fast or pounding heartbeats
  • Skin rash, hives, sores in your mouth, or blistering and peeling skin

Call your doctor at once if you have:

  • New or worsening mental depression;
  • Mood changes including aggression, hostility, anxiety, panic attacks;
  • Hallucinations (seeing things that are not there);
  • Thoughts of suicide; or
  • An extreme increase in activity and talking (mania).

Armodafinil can decrease or increase the activity of enzymes in the liver that metabolize other drugs. Taking armodafinil with other drugs that make you sleepy or slow your breathing can cause dangerous side effects or death. Ask your doctor before taking a sleeping pill, narcotic pain medicine, prescription cough medicine, a muscle relaxer, or medicine for anxiety, depression, or seizures.

Modafinil (Provigil), another medication similar to armodafinil, has been associated with congenital disabilities in some babies of mothers who were taking modafinil while pregnant.

  • It is not known if armodafinil also causes these defects. Tell your doctor if you are pregnant or plan to become pregnant.
  • It is unknown if armodafinil passes into breast milk. 
  • Armodafinil may decrease the effectiveness of hormonal birth control such as pills, patches, or rings. This could cause pregnancy. 
  • Use a barrier method of birth control (such as a condom or diaphragm with spermicide) to prevent pregnancy while using this medication and for at least 1 month after your last dose. 
  • Armodafinil may interfere with certain lab tests (including urine drug screening). 

Be sure your doctor and lab personnel know you are using armodafinil.
