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 melphalan, the following
should be considered:
Allergies - Tell your doctor if you have ever had any unusual or
allergic reaction to melphalan or chlorambucil.
Pregnancy - Tell your doctor if you are pregnant or if you intend
to have children. There is a chance that this medicine may cause birth defects
if either the male or female is taking it at the time of conception or if
it is taken during pregnancy. In addition, many cancer medicines may cause
sterility which could be permanent. Sterility has been reported with melphalan
and the possibility should be kept in mind. Be sure that you have discussed this with your doctor before taking this
medicine. It is best to use some kind of birth control while you are taking
melphalan. Tell your doctor right away if you think you have become pregnant
while taking melphalan.
Breast-feeding - Tell your doctor if you are breast-feeding or if
you intend to breast-feed during treatment with this medicine. Because melphalan
may cause serious side effects, breast-feeding is not recommended while you
are taking it.
Children - Although there is no specific information comparing
use of melphalan 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 the
use of melphalan 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
melphalan, it is especially important that your health care professional know
