WHAT ZILAREX IS USED FOR
The name of your medicine is Zilarex. It contains the active ingredient cetirizine hydrochloride.
Cetirizine hydrochloride is an antihistamine used to relieve the symptoms of hayfever (also known as seasonal allergic rhinitis) and perennial allergic rhinitis e.g. sneezing, an itchy or runny nose and itchy, watering or red eyes. It is also used to treat some itchy skin rashes such as hives (also known as chronic idiopathic urticaria).
Ask your doctor if you have any questions about why Zilarex was prescribed for you.
Your doctor may have prescribed Zilarex for another reason.
There is no evidence that Zilarex is addictive.

HOW TO TAKE ZILAREX
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to take
The usual dose for adults and children 12 years and over is one tablet daily. Some adults may require only half a tablet per day (e.g. people with kidney problems). Some adults may require the maximum dose of two tablets (20mg) per day.
The usual dose for children 6-12 years of age is half a tablet twice a day. Zilarex is not recommended for children under 6 years of age.
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly how much to take.
Follow the instructions they give you.
If you take the wrong dose, Zilarex may not work as well and your problem may not improve.
How to take it
The tablets should be swallowed with a glass of water. They can be taken with or without food.
If you need to break the Zilarex tablet, hold tablet with both hands and snap along break line.
When to take Zilarex
If this medicine makes you feel drowsy, take the tablet in the evening or at bed time.
Take your medicine at about the same time each day.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Zilarex can be taken when allergic symptoms start showing:
- hayfever may begin with itchiness in the throat, nose or eyes
- hives will usually cause your skin to itch and you may notice pink lumps appearing.
People suffering from hayfever will usually need to take Zilarex during spring and summer, when there is more pollen in the air to trigger symptoms.
How long to take Zilarex
You can stop taking Zilarex when you obtain relief from your symptoms. It can be restarted if your symptoms recur.
If your condition does not improve after a few days or it is not well controlled by Zilarex, speak to your doctor or pharmacist.
If you forget to take it
If you (or a child 12 years or over) forget to take a dose, take one dose as soon as you remember, but wait at least 12 hours before taking the next dose. If you forget to give your child (6-12 years) their dose, give them one dose as soon as you remember, but wait at least 6 hours before giving the next dose to your child.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much
Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26 or New Zealand 0800 POISON or 0800 764 766) or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else has taken too much Zilarex. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much Zilarex, you may feel confused, drowsy, dizzy, restless, tired and may experience diarrhoea, headaches, rash, a rapid heart rate and tremors.
