What MODAFINIL SANDOZ is used for
MODAFINIL 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 decreases this unwanted excessive daytime sleepiness.
With OSAHS, daytime sleepiness may occur due to an interrupted night time sleep. MODAFINIL only treats the symptom of sleepiness and does not treat the cause of OSAHS. Whilst taking MODAFINIL 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 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 increases wakefulness.
Your doctor may have prescribed MODAFINIL for another reason. Ask your doctor if you have any questions about why MODAFINIL has been prescribed for you.

How to take MODAFINIL SANDOZ
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 MODAFINIL 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 200mg to 400mg.
Each day you should take either:
- two MODAFINIL tablets
- up to four MODAFINIL tablets.
For SWSD, a dose of 200mg 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 MODAFINIL tablets either:
- as two separate doses, one in the morning and one at midday,
- as one dose, in the morning.
For narcolepsy or OSAHS, do not take your MODAFINIL tablets later than midday, or you may have trouble sleeping at night.
For SWSD, you should take your MODAFINIL tablets as a single dose 1 hour prior to commencing your shift work.
Swallow the tablets 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. 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 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 tablets, just take the next dose at your usual time. Do not take an extra dose to "catch up".
While you are taking MODAFINIL SANDOZ
Things you must do
If you become pregnant while you are taking MODAFINIL, stop taking it and tell your doctor immediately.

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

Things to be careful of
MODAFINIL may reduce the effectiveness of oral contraceptives. If you are using these forms of contraceptives while taking MODAFINIL (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.
