What is the most important information I should know about Armodafinil?

Armodafinil is a federal controlled substance (C-IV) because it can be abused or lead to dependence. Keep armodafinil in a safe place to prevent misuse and abuse. Selling or giving away armodafinil may harm others, and is against the law. Tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or street drugs.

Armodafinil may cause serious side effects including a serious rash or a serious allergic reaction that may affect parts of your body such as your liver or blood cells. Any of these may need to be treated in a hospital and may be life-threatening.

Stop taking armodafinil and call your doctor right away or get emergency help if you have any of these symptoms:

  • skin rash, hives, sores in your mouth, or your skin blisters and peels
  • swelling of your face, eyes, lips, tongue, or throat
  • trouble swallowing, breathing, or hoarseness
  • fever, shortness of breath, swelling of the legs, yellowing of the skin or whites of the eyes, or dark urine.

If you have a severe rash with armodafinil, stopping the medicine may not keep the rash from becoming life-threatening or causing you to be permanently disabled or disfigured.

Armodafinil is not approved for use in children for any medical condition.

It is not known if armodafinil is safe and effective in children under the age of 18.

What is armodafinil?

Armodafinil is a prescription medicine used to improve wakefulness in adults who are very sleepy due to one of the following diagnosed sleep disorders:

  • narcolepsy
  • obstructive sleep apnea (OSA). Armodafinil is used with other medical treatments for this sleep disorder. Armodafinil does not take the place of using your CPAP machine or other treatments that your doctor has prescribed for this condition. It is important that you continue to use these treatments as prescribed by your doctor.
  • shift work disorder (SWD)

Armodafinil will not cure these sleep disorders. Armodafinil may help the sleepiness caused by these conditions, but it may not stop all your sleepiness. Armodafinil does not take the place of getting enough sleep. Follow your doctor's advice about good sleep habits and using other treatments.

Do not take armodafinil tablets if you:

  • are allergic to any of its ingredients. See the end of this Medication Guide for a complete list of ingredients in armodafinil tablets.
  • have had a rash or allergic reaction to either armodafinil (NUVIGIL®) or modafinil (PROVIGIL®). These medicines are very similar.

Before you take armodafinil, tell your doctor about all of your medical conditions, including if you:

  • have a history of mental health problems, including psychosis
  • have heart problems or had a heart attack
  • have high blood pressure. Your blood pressure may need to be checked more often while taking armodafinil.
  • have liver or kidney problems
  • have a history of drug or alcohol abuse or addiction
  • are pregnant or planning to become pregnant. It is not known if armodafinil will harm your unborn baby.
    Pregnancy Registry: There is a registry for women who become pregnant during treatment with armodafinil. The purpose of this registry is to collect information about the safety of armodafinil during pregnancy. Contact the registry as soon as you learn that you are pregnant, or ask your doctor to contact the registry for you. You or your doctor can get information and enroll you in the registry by calling 1-866-404-4106.
  • are breastfeeding. It is not known if armodafinil passes into your milk. Talk to your doctor about the best way to feed your baby if you take armodafinil.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Armodafinil and many other medicines can interact with each other, sometimes causing side effects. Armodafinil may affect the way other medicines work, and other medicines may affect how armodafinil works. Your dose of armodafinil or certain other medicines may need to be changed.

Especially, tell your doctor if you use or take:

  • a hormonal birth control method, such as birth control pills, shots, implants, patches, vaginal rings, and intrauterine devices (IUDs). Hormonal birth control methods may not work while you take armodafinil. Women who use one of these methods of birth control may have a higher chance for getting pregnant while taking armodafinil, and for 1 month after stopping armodafinil. You should use effective birth control while taking armodafinil and for 1 month after your final dose. Talk to your doctor about birth control choices that are right for you while taking armodafinil.

Know the medicines you take. Keep a list of them and show it to your doctor and pharmacist when you get a new medicine. Your doctor or pharmacist will tell you if it is safe to take armodafinil and other medicines together. Do not start any new medicines with armodafinil unless your doctor has told you it is okay.
