Before Using This MedicineIn deciding to use a medicine,
the risks of taking the medicine must be weighed against the good it will
do. This is a decision you and your doctor will make. For thyrotropin, the
following should be considered:
Allergies - Tell your doctor if you have ever received thyrotropin
or ever had any unusual or allergic reaction to thyrotropin. Also tell your
health care professional if you are allergic to any other substances, such
as foods, preservatives, or dyes.
Pregnancy - Studies on effects in pregnancy have not been done
in either humans or animals.
Breast-feeding - It is not known whether thyrotropin passes into

many of them may be used safely while breast-feeding. Mothers who are taking
this medicine and who wish to breast-feed should discuss this with their doctor.
Children - This medicine has been tested in children and has
not been shown to cause different side effects or problems than it does in
adults.
Older adults - Many medicines have not been studied specifically
in the elderly. Therefore, it may not be known whether they work exactly the
same way they do in younger adults. Although there is no specific information
comparing the use of thyrotropin in the elderly with use in other age groups,
this medicine is not expected to cause different side effects or problems
in older people than it does in younger adults.
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 receiving
thyrotropin, it is especially important that your health care professional
know if you are taking any of the following:
-
Thyroid hormones - You may not respond as strongly to thyrotropin
if you have been taking thyroid hormones regularly

problems may affect the use of thyrotropin. Make sure you tell your doctor

causes the heart to work harder, which may make these conditions worse
