What is in this leaflet

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

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

What MODAFINIL GH is used for

MODAFINIL GH 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 GH decreases this unwanted excessive daytime sleepiness.


With OSAHS, daytime sleepiness may occur due to an interrupted night time sleep. MODAFINIL GH only treats the symptom of sleepiness and does not treat the cause of OSAHS. Whilst taking MODAFINILGH 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, MODAFINILGH may be prescribed to keep you awake during your work shift.


Precisely how modafinil 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 GH increases wakefulness.

Your doctor may have prescribed MODAFINIL GH for another reason. Ask your doctor if you have any questions about why MODAFINIL GH has been prescribed for you.

How to take MODAFINIL GH

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 GH tablet contains 100 mg of modafinil.

The usual daily dose of modafinil depends on individual response.

Do not exceed the recommended daily dose unless directed to do so by your doctor.

Narcolepsy or OSAHS

For sleepiness associated with narcolepsy or OSAHS, the dose ranges from 200 mg to 400 mg.

Each day you should take either:

  • two MODAFINIL GH tablets; or
  • up to four MODAFINIL GH tablets.


For SWSD, a dose of 200mg is recommended.

How to take it

Narcolepsy or OSAHS

For sleepiness associated with narcolepsy or OSAHS, you should take your MODAFINIL GH 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 GH tablets later than midday, or you may have trouble sleeping at night.


For SWSD, you should take your MODAFINIL GH tablets as a single dose 1 hour prior to commencing your shift work.

Swallow the tablets whole with a little water.


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 GH. 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 GH 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 MODAFINIL GH tablets, just take the next dose at your usual time. Do not take an extra dose to "catch up".

If you take too much (overdose)

Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26 in Australia or 0800 764 766 in New Zealand), or go to
the emergency department of your nearest hospital, if you think you or anyone else may have taken too much modafinil. Do this, even if there are no signs of discomfort or poisoning.

While you are taking it

Things you must do

If you become pregnant while you are taking MODAFINIL GH, 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 MODAFINIL GH.

Tell your doctor if you believe that modafinil is not helping your condition. Your doctor may need to change the dose.

Things you must not do

Do not give MODAFINIL GH to anyone else, even if they have the same symptoms as you.

Things to be careful of

Modafinil may reduce the effectiveness of oral contraceptives. If you are using these forms of contraceptives while taking MODAFINIL GH (and for 1 month after you stop treatment with modafinil) 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 modafinil affects you.
