What is in this leaflet

Please read this leaflet carefully before you take Zodac tablets.

This leaflet answers some common questions about Zodac. It does
not contain all available information, nor does it take the place
of talking to you doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed
the risks of you taking Zodac against the benefits this medicine is
expected to have for you.

You should ask your doctor or pharmacist if you have any questions
about Zodac or if you have any trouble before, during or after taking

What Zodac is used for

Zodac tablets contain an antihistamine called cetirizine hydrochloride.
Antihistamines relieve the symptoms of hayfever (e.g. sneezing and
an itchy, runny, blocked-up nose) and other similar allergic conditions.
They may also be used to treat some itchy skin rashes such as hives.

Your doctor may have prescribed Zodac for another reason. Ask
your doctor if you have any questions about why Zodac has been prescribed
for you or your child.

There is no evidence that Zodac is addictive.

Zodac helps most people with hayfever and allergy symptoms,
but it may have unwanted side effects in a few people. All medicines
can have side effects. Sometimes they are serious, most of the time
they are not. You may need medical treatment if you get some of the
side effects. Ask your doctor or pharmacist to answer any questions
you may have. Tell your doctor or pharmacist if you notice any of
the following and they worry you:

  • drowsiness/sleepiness
  • dizziness or lightheadedness
  • dry mouth
  • headache
  • stomach upset (e.g. nausea and vomiting)
  • restless or agitated feeling.

These side effects are usually mild and short-lived. Other side
effects not listed above may occur in some patients. Do not be alarmed
by this list of possible side effects. You may not experience any
of them.

Tell your doctor immediately or go to casualty at your nearest
hospital if you notice any of the following:

  • swelling of the face, lips, mouth and tongue
  • severe persistent diarrhoea
  • an allergic reaction (e.g. itchy skin, rash, swelling).

These may be signs of a serious allergic reaction. Other side
effects not listed above may also occur in some patients.

Tell your doctor if you notice anything else that is making
you feel unwell.

After Using Zodac


Keep your Zodac tablets in the blister pack until it is time
to take them. If you take the tablets out of their packaging, they
may not keep well.

Keep Zodac in a cool dry place where the temperature stays below
25 deg C.

Do not store it or any other medicine in the bathroom or near
a sink. Do not leave it in the car or on windowsills. Heat and dampness
can destroy some medicines.

Keep your tablets where children cannot reach them. A locked
cupboard at least one-and-one-half meters above the ground is a good
place to store medicines.


If your doctor tells you to stop taking Zodac or the tablets
have passed their expiry date, ask your pharmacist or doctor what
to do with the any tablets that are leftover.
