What NUVIGIL is used for
NUVIGIL is used to improve wakefulness in people with excessive daytime sleepiness associated with the medical condition known as narcolepsy or with Obstructive Sleep Apnoea/Hypopnoea Syndrome (OSAHS), or shift work sleep disorder (SWSD).
In narcolepsy, there is a sudden and irresistible tendency to fall asleep during normal waking hours. This happens at unpredictable times, even when it is inappropriate or may be unsafe to do so. NUVIGIL decreases this unwanted excessive daytime sleepiness.
With OSAHS, daytime sleepiness may occur due to an interrupted night time sleep. NUVIGIL only treats the symptom of sleepiness and does not treat the cause of OSAHS. Whilst taking NUVIGIL you should continue with treatments intended to help manage your underlying medical condition, such as Continuous Positive Airway Pressure, unless your doctor tells you otherwise.
If you have been diagnosed with moderate to severe chronic Shift Work Sleep Disorder (SWSD) and non-drug therapies have been unsuitable or unsuccessful, NUVIGIL may be prescribed to keep you awake during your work shift.
Precisely how NUVIGIL works is not known, but it is known that it acts on the central nervous system (the brain). It differs from other stimulant medicines that promote wakefulness. NUVIGIL increases wakefulness.
Your doctor may have prescribed NUVIGIL for another reason. Ask your doctor if you have any questions about why NUVIGIL has been prescribed for you.

How to take NUVIGIL
It is important that you take this medicine as directed by the doctor. Your doctor will tell you how much you should take, when and how often. Follow your doctor's instructions. If you are unsure ask your doctor or pharmacist.
How much should you take
Each NUVIGIL tablet contains 50mg, 150mg or 250mg of armodafinil.
The usual daily dose of armodafinil depends on individual response. For sleepiness associated with narcolepsy or OSAHS, the dose ranges from 150mg to 250mg.
For SWSD, a dose of 150mg is recommended.
Do not exceed the recommended daily dose unless directed to do so by your doctor.
When and how should you take the tablets
For sleepiness associated with narcolepsy or OSAHS, you should take your NUVIGIL tablet as one dose, in the morning.
For narcolepsy or OSAHS, do not take your NUVIGIL tablet later than midday, or you may have trouble sleeping at night.
For SWSD, you should take your NUVIGIL tablet as a single dose 1 hour prior to commencing your shift work.
Swallow the tablet whole with a little water.
Take your dose before food as food can slow down the rate at which the treatment enters your blood stream and may delay the effects of your medication.
If you are currently on another treatment for narcolepsy, your doctor will advise you how best to withdraw from that treatment and begin taking NUVIGIL. Other stimulants used for narcolepsy may cause a "high" feeling. Be aware therefore that you may feel different as you withdraw from other stimulants. NUVIGIL is not associated with this "high" feeling. It works on excessive daytime sleepiness.
NUVIGIL only treats the symptom of sleepiness. Other treatments intended to help manage your underlying medical condition should still be used regularly, unless your doctor tells you otherwise. You should commence or continue disease-modifying interventions (for example, Continuous Positive Airway Pressure).
REMEMBER: This medicine is only for you. Only a doctor can prescribe it for you. Never give it to anyone else. It may harm them, even if their symptoms appear to be the same as yours.
If you forget to take it
If you miss a dose of NUVIGIL tablets, just take the next dose at your usual time. Do not take an extra dose to "catch up".
While you are taking NUVIGIL
Things you must do
Tell your doctor if you are planning to become pregnant.
If you become pregnant while you are taking NUVIGIL, stop taking it and tell your doctor immediately.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking NUVIGIL.
Tell your doctor if you believe that NUVIGIL is not helping your condition. Your doctor may need to chan
ge the dose.
Things you must not do
Do not give NUVIGIL to anyone else, even if they have the same symptoms as you.
Things to be careful of
NUVIGIL may reduce the effectiveness of oral contraceptives. If you are using these forms of contraceptives while taking NUVIGIL (and for 1 month after you stop treatment with NUVIGIL) you should either use an alternative birth control method or another effective birth control method together with your current contraceptive.
Do not drive or operate machinery until you know how NUVIGIL affects you.
NUVIGIL may cause you to have a serious rash.
Stop taking NUVIGIL and call your doctor right away or get emergency treatment if you have a skin rash, hives, sores in your mouth, or your skin blisters and peels, or if you have any sudden wheeziness, difficulty in breathing, swelling, or itching (especially affecting the whole body).
NUVIGIL may cause the following side effects in some people. In clinical studies, these side effects also occurred in people who received non-active (sugar) tablets. Tell your doctor if you notice any of these:
- dry mouth
- poor appetite
- runny nose
- sore throat
- nervous feeling
- back pain
- feeling anxious
- upset stomach

Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that makes you feel unwell. Do not be alarmed by this list of possible side effects. You may not experience any of them.
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26), or go to the emergency department of your nearest hospital, if you think you or anyone else may have taken too much NUVIGIL. Do this, even if there are no signs of discomfort or poisoning.
