Full Consumer Medicine Information (CMI)
This leaflet provides important information about using MODAFINIL VIATRIS. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using MODAFINIL VIATRIS.
Where to find information in this leaflet:
1. Why am I using MODAFINIL VIATRIS?
MODAFINIL VIATRIS contains the active ingredient modafinil.
MODAFINIL VIATRIS 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. MODAFINIL VIATRIS decreases this unwanted excessive daytime
sleepiness.
With OSAHS, daytime sleepiness may occur due to an interrupted nighttime sleep. MODAFINIL
VIATRIS only treats the symptom of sleepiness and does not treat the cause of OSAHS.
Whilst taking MODAFINIL VIATRIS 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, MODAFINIL VIATRIS
may be prescribed to keep you awake during your work shift.
Precisely how MODAFINIL VIATRIS 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. MODAFINIL VIATRIS increases wakefulness.
Your doctor may have prescribed MODAFINIL VIATRIS for another reason. Ask your doctor
if you have any questions about why MODAFINIL VIATRIS has been prescribed for you.

4. How do I use MODAFINIL VIATRIS?
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 to take
Each MODAFINIL VIATRIS tablet contains 100mg of modafinil.
The usual daily dose of modafinil depends on individual response. For sleepiness associated
with narcolepsy or OSAHS, the dose ranges from 200 mg to 400 mg.
Each day you should take either:
two MODAFINIL VIATRIS tablets
or
up to four MODAFINIL VIATRIS tablets
For SWSD, a dose of 200 mg is recommended.
Do not exceed the recommended daily dose unless directed to do so by your doctor.
Follow the instructions provided and use MODAFINIL VIATRIS until your doctor tells
you to stop.
When to take MODAFINIL VIATRIS
For sleepiness associated with narcolepsy or OSAHS, you should take your MODAFINIL
VIATRIS tablets either:
as two separate doses, one in the morning and one at midday,
or
as one dose, in the morning.
For narcolepsy or OSAHS, do not take your MODAFINIL VIATRIS tablets later than midday,
or you may have trouble sleeping at night.
For SWSD, you should take your MODAFINIL VIATRIS tablets as a single dose 1 hour prior
to commencing your shift work.
How to take MODAFINIL VIATRIS
swallow tablet whole with a little water
NOTE: Your doctor may start your treatment with less than two tablets a day
If you need more than two tablets per day, your doctor should increase the dose stepwise,
one additional tablet at a time, depending on how you respond to the treatment. The
highest dose is four tablets per day.
If you are currently on another treatment for narcolepsy, your doctor will advise
you how best to withdraw from that treatment and begin taking MODAFINIL VIATRIS. Other
stimulants used for narcolepsy may cause a “high” feeling. Be aware therefore that
you may feel different as you withdraw from other stimulants.
MODAFINIL VIATRIS 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 use MODAFINIL VIATRIS
MODAFINIL VIATRIS should be used regularly at the same time each day.
If you miss your dose, just take the next dose at your usual time
and it is almost time for your next dose, skip the dose you missed and take your next
dose when you are meant to.
Do not take a double dose to make up for the dose you missed.
If you use too much MODAFINIL VIATRIS
If you think that you have used too much MODAFINIL VIATRIS, you may need urgent medical
attention.
You should immediately:
phone the Poisons Information Centre
(by calling 13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
