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, simeticone and citric acid. Each sachet of Carbex® granules contains 1.26 grams of sodium bicarbonate and 42 mg (milligrams) of simeticone. 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 simeticone 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 sodium diet.

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 doctor or nurse if you are worried that you have taken too much.
