Proper Use of barium sulfate

This section provides information on the proper use of a number of products that contain barium sulfate. It may not be specific to Acb. Please read with care.

A doctor or other trained health professional will give you or your child this medicine in a hospital. This medicine is given by mouth. You will swallow the barium liquid or paste just before a CT scan or x-ray.

Your doctor may tell you not to eat or drink anything the night before your test. Barium will work better if your stomach and bowels are empty.

It is important to drink plenty of liquids during and after the test. Barium sulfate may cause severe constipation.

Barium sulfate is also available as an enema and given through the rectum.

Precautions While Using Acb

Your doctor will check your or your child's progress closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to receive it.

Serious allergic reactions may occur while you are receiving this medicine. Tell your doctor right away if you have a rash, itching, noisy breathing, trouble breathing, lightheadedness, dizziness, or fainting after receiving this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Usual Adult Dose for Computed Tomography
