1. Why am I using ALLEREZE?

ALLEREZE contains the active ingredient Loratadine. ALLEREZE is a non-sedating antihistamine.

ALLEREZE is used to relieve the symptoms of sneezing; runny nose; watery, itchy or red eyes in the following allergic conditions:

  • hayfever (also known as seasonal allergic rhinitis), which usually occurs during the warmer seasons
  • perennial allergic rhinitis, which may occur throughout the year.

ALLEREZE can also be used to relieve the symptoms of hives or nettle rash (also known as chronic urticaria), which appears as a pinkish skin rash with itchy, swollen lumps.

The body releases histamine in response to substances it recognises as ‘foreign’, such as pollen, dust and dyes. This can cause the symptoms mentioned above. Antihistamines can relieve allergic symptoms by blocking the effects of histamine.

The severity of your condition will depend how sensitive you are to ‘foreign substances’.

Ask your doctor or pharmacist if you have any questions about why ALLEREZE has been recommended.

They may have recommended ALLEREZE for another reason.

There is no evidence that ALLEREZE is addictive.

2. What should I know before I use ALLEREZE?


Do not use ALLEREZE if:

  • you are allergic to any other medicines containing:
    – loratadine (e.g. Claratyne, Clarinase, Lorastyne)
    – desloratadine (e.g. Claramax)
    – or any of the ingredients listed at the end of this leaflet.

Always check the ingredients to make sure you can use this medicine.

Some of the symptoms of an allergic reaction may include skin rash, itching or hives; swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing, wheezing or shortness of breath.

  • you are giving to children under 12 years of age
  • they have passed the expiry date (EXP) printed on the pack.

If you take this medicine after the expiry date, it may not work as well.

  • the packaging shows signs of tampering or the tablets do not look quite right.
  • you are not sure whether you should start taking this medicine, talk to your doctor or pharmacist.

Check with your doctor or pharmacist if you:

  • have any other medical conditions
  • take any medicines for any other condition
  • are allergic to any other medicines, foods, dyes or preservatives.
  • have liver problems

Check with your doctor or pharmacist if you are pregnant or intend to become pregnant.

Talk to your doctor or pharmacist if you are breastfeeding or intend to breastfeed.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect ALLEREZE.

4. How do I use ALLEREZE?

Follow all directions given to you by your doctor and pharmacist carefully.

They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist.

How much to take

  • Adults and children aged 12 years and older:
  • Take one tablet (10 mg) daily.

Swallow the tablet with a glass of water.

When to take ALLEREZE

ALLEREZE can be taken with or without food.

ALLEREZE can be taken when the allergic symptoms start showing:

  • hayfever may begin with an 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 (seasonal allergic rhinitis) are more likely to experience symptoms during spring and summer, when there is more plant pollen in the air to trigger off symptoms.

You can stop taking ALLEREZE when you obtain relief from the symptoms. It can be restarted if the symptoms recur.

If your condition does not improve or is not well controlled by ALLEREZE, speak to your doctor or pharmacist.

If you use too much ALLEREZE

If you think that you have used too much ALLEREZE, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (Australia telephone 13 11 26) for advice, or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

If you take too much ALLEREZE, you may feel sleepy, have heart palpitations or a headache.

5. What should I know while using ALLEREZE?

Things you should do

  • Tell all the doctors, dentists and pharmacists who are treating you that you are taking ALLEREZE.
  • If you are planning to have skin tests to find out what you are allergic to, stop taking ALLEREZE for 48 hours before the test.

ALLEREZE may interfere with the true results of the skin tests.

  • If you become pregnant while taking ALLEREZE, tell your doctor.
  • If you already know which substances set off your allergies, keep a supply of ALLEREZE ready so you can control the symptoms when they start appearing.
  • Try to avoid contact with the substances you are allergic to.

Things you should not do

  • Do not give ALLEREZE to anyone else, even if they have similar symptoms to you.
  • Other people who think ALLEREZE may help their own condition should consider asking their doctor or pharmacist before taking ALLEREZE for the first time.
  • Do not use ALLEREZE to treat any other conditions unless your doctor or pharmacist tells you to.
