An x-ray examination of the gallbladder is accomplished by the patient taking pills the evening before the x-ray examination is performed. The pills make the bile in the gallbladder dense so that it appears white on the x-rays. The examination is a test to determine if gallstones are present.

Sometimes it is necessary to take the pills twice to make the gallbladder sufficiently dense. This does not necessarily mean gallbladder disease is present, but you should know we may have to ask you to take the pills a second consecutive evening.

Most patients experience no significant discomfort or inconvenience. However, the pills may act as a laxative with approximately half the patients experiencing more than slight diarrhea at some time during the evening before, the day of, or the day following the examination. If the diarrhea should be severe enough to require treatment, contact your personal physician. This possibility should be considered in scheduling an important business or social activity the evening before, and the day or evening of the examination.

Patient Preparation:

Follow these directions exactly. Ignore the slightly different directions on the packet of Telapaque tablets given to you.

  1. At noon on the day before the examination, eat a full lunch containing fatty foods (such as meat, dairy products and fried food).

  2. Starting at 2 p.m., after the above lunch, take 1 Telapaque tablet with a full glass of water every hour until all six tablets are gone (that is one tablet at 2, 3, 4, 5, 6 and 7 p.m.). Stay as close to this schedule as possible, but most importantly, take all the tablets.

  3. At 6 p.m., the evening before the examination, eat a light supper containing no fatty foods. Avoid meat, eggs and dairy products.

  4. After supper, remember the 7 p.m. Telapaque tablet. You may drink moderate amounts of water, plain tea, or black coffee, and take necessary medication until the time of the examination. If you are also having a G.I. series, take nothing by mouth after midnight except necessary medications with a small amount of water.

Plan to spend approximately 45 minutes in the Department of Radiology.
