Before Having This Test

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
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

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
