Bentiromide (Diagnostic)
Before Having This TestIn deciding to use a diagnostic test, any risks of the test must be weighed
against the good it will do. This is a decision you and your doctor will make.
Also, test results may be affected by other things. For the test using bentiromide,
the following should be considered:
Allergies - Tell your doctor if you have ever had any unusual or
allergic reaction to bentiromide. Also tell your doctor if you are allergic
to any other substances, such as foods, preservatives, or dyes.
Diet - Eating prunes or cranberries shortly before
the bentiromide test period starts will affect test results. Avoid these foods
for 3 days before the test.
Pregnancy - Studies with bentiromide have not been done in pregnant
women. However, in animal studies bentiromide has not been shown to cause
birth defects or other problems.
Breast-feeding - It is not known whether bentiromide passes into
the breast milk. However, this medicine has not been reported to cause problems
in nursing babies.
Children - Studies on this medicine have been done only in older
children and adult patients, and there is no specific information comparing
use of bentiromide in children up to 6 years of age with use in other age
groups.
Older adults - Many medicines have not been studied specifically
in older people. Therefore, it may not be known whether they work exactly
the same way they do in younger adults or if they cause different side effects
or problems in older people. There is no specific information comparing use
of bentiromide in the elderly with use in other age groups.
Other medicines - Although certain medicines should not be used
together at all, in other cases two different medicines may be used together
even if an interaction might occur. In these cases, your doctor may want to
change the dose, or other precautions may be necessary. When you are taking
bentiromide it is especially important that your doctor know if you are taking
or using any of the following:
-
Acetaminophen (e.g., Tylenol) or
-
Chloramphenicol (e.g., Chloromycetin) or
-
Local anesthetics (e.g., benzocaine and lidocaine) or
-
Para-aminobenzoic acid (PABA)-containing preparations (e.g., sunscreens
and some multivitamins) or
-
Procainamide (e.g., Pronestyl) or
-
Sulfonamides (sulfa medicines) or
-
Thiazide diuretics (water pills) - Use of these medicines during
the test period will affect the test results
-
Pancreatic supplements (e.g., pancrelipase) - Use of pancreatic
supplements may give false test results
Other medical problems - The presence of other medical
problems may affect the results of the test. Make sure you tell your doctor
if you have any other medical problems, especially:
-
Disease of the stomach and intestines or
-
Kidney disease or
-
Liver disease (severe) - These medical problems may cause false
test results
Preparation for This TestYour doctor may ask you to avoid certain medicines or foods for at least
72 hours before this test is done. Follow your doctor's
instructions carefully
. Otherwise, this test may not work and may have
to be done again.
Unless otherwise directed by your doctor:
-
Do not eat anything after midnight the night before the test. Some
foods may affect the results of the test.
-
Urinate before taking bentiromide. You should have an empty bladder
when you take the test.
-
After taking bentiromide, drink a large glass of water (at least
8 ounces). Drink another large glass of water in 2 hours and then 2 more glasses
of water in the next 4 hours. This will help increase the amount of urine,
which is needed for testing.
