1. What Carbex® is and what it
is used for
The name of your medicine is Carbex®. It is
presented as effervescent granules in
sachets together with a liquid for
administration (the granules must be taken
with the liquid).
The active ingredients of Carbex® are
sodium bicarbonate, simethicone and citric
acid. Each sachet of Carbex® granules
contains 1.26 grams of sodium bicarbonate
and 42 mg (milligrams) of simethicone. The
bottle of liquid contains 1 gram of citric acid.
Carbex® is used during barium meal X-rays
of the stomach to improve the image of the
X-ray. When the granules are swallowed with
the liquid, Carbex® produces carbon dioxide
gas in the stomach. This makes the stomach
larger which allows better coating of the
barium to the stomach wall and helps to
produce better detail in the X-ray picture. The
simethicone prevents too much foaming in
the stomach which may be caused by the
carbon dioxide gas.

2. Before you use Carbex®
Do not take Carbex® if you are allergic to
any of the ingredients listed in the “Further
Information” section below.
Carbex® contains methyl paraben (E218)
and propyl paraben (E216) which may cause
allergic reactions (possibly delayed).
Tell your doctor if you think you are allergic
to any of the ingredients in Carbex® .
This medicinal product contains 15mmol of
sodium (350 milligrams). To be taken into
consideration by patients on a controlled

Taking other medicines
There are no reported problems of Carbex®
interfering with other medicines taken at the
same time. Please inform your doctor or
pharmacist if you are taking, or have recently
taken, any other medicine – even those
which your doctor has not prescribed for
you, but which you may have bought
yourself without a prescription.

Pregnancy and breast-feeding:
There are no reported problems when
Carbex® has been given during pregnancy
or breast feeding.
Driving and using machines
It is not known whether Carbex® affects
your ability to drive or operate machinery.
3. How to use Carbex®
A doctor or nurse will help you to take
Carbex® before your X-ray. The contents
of one sachet of Carbex® granules should
be placed on your tongue and then
immediately washed down with 10ml of the
liquid. It is recommended that the barium
(for the X-ray) should be swallowed 30
seconds later.
If you think that you have been given
too much Carbex®
Since you have been given this medicine by
a doctor or nurse it is unlikely that you will
be given too much. However, tell the

have taken too much.
