Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about NUVIGIL tablets. As this leaflet does not contain all the available information, it is important that you talk to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you receiving NUVIGIL against the benefits this medicine is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet. You may need to read it again.

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

If you could become pregnant, you should confirm by a pregnancy test that you are not pregnant within a week prior to starting treatment.

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 change 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 hormonal contraceptives (including the contraceptive pill, implants, injectables and some intrauterine devices (IUDs)).

If you are using hormonal contraception, you should use an alternative non-hormonal method of birth control together with your current contraceptive whilst taking NUVIGIL and for 2 months after you stop treatment with NUVIGIL.

Do not drive or operate machinery until you know how NUVIGIL affects you.
