Diphtheria Antitoxin (Systemic)
Before Using This MedicineIn deciding to use a medicine,
the risks of using the medicine must be weighed against the good it will do.
This is a decision you and your doctor will make. For diphtheria antitoxin,
the following should be considered:
Allergies - Tell your doctor if you have ever had any unusual or
allergic reaction to diphtheria antitoxin, to horses, or to any products of
horse origin. Also tell your health care professional if you are allergic
to any other substances, such as preservatives. Before giving you this medicine,
your doctor will do a skin test or conjunctival (eye) test to see whether
you are at risk of having a serious allergic reaction to diphtheria antitoxin
or horse serum (contained in this medicine).
Pregnancy - Studies on effects in pregnancy have not been done
in either humans or animals.
Breast-feeding - It is not known whether diphtheria antitoxin passes
into the breast milk. Although most medicines pass into breast milk in small
amounts, many of them may be used safely while breast-feeding. Mothers who
have received this medicine and who wish to breast-feed should discuss this
with their doctor.
Children - Although there is no specific information comparing
use of diphtheria antitoxin in children with use in other age groups, this
medicine is not expected to cause different side effects or problems in children
than it does in adults.
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 diphtheria antitoxin in the elderly with use in other age groups. However,
there is no evidence that the effects of diphtheria antitoxin in older adults
differ from those in younger persons.
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. Tell your health care
professional if you are taking any other prescription or nonprescription (over-the-counter
[OTC]) medicine.
Other medical problems - The presence of other medical
problems may affect the use of diphtheria antitoxin. Make sure you tell your
doctor if you have any other medical problems.
