1. WHAT TAMOXIFEN TABLETS ARE AND WHAT THEY ARE USED FOR
Tamoxifen is one of a group of medicines called anti-oestrogens.
Tamoxifen Tablets may be used for:

treatment of breast cancer

some forms of female infertility caused by a failure to produce and
release eggs
(ovulate) properly.

reduce the risk of developing breast cancer occurring in those women
who have an
increased likelihood of developing breast cancer (your risk). It is
important that your
healthcare professional calculates your risk of developing breast
cancer and discusses
the result with you before commencing treatment. There are a number of
specific
tools available to calculate breast cancer risk, based on information
such as your
age, family history, genetics, reproductive factors (e.g. age when
periods started and
stopped, had children or not, taken or taking hormonal replacement
therapy and/or
oral contraceptive pill) and history of breast disease. Although the
tools can estimate
your risk, it doesn’t mean you will get breast cancer, being at
increased risk means
you have a higher chance of developing breast cancer. If you and your

POSOLOGY AND METHOD OF ADMINISTRATION
POSOLOGY
1.
Breast Cancer
Adults
The recommended daily dose of tamoxifen is normally 20mg. No
additional
benefit, in terms of delayed recurrence or improved survival in
patients, has
been demonstrated with higher doses. Substantive evidence supporting
the use
of treatment with 30-40mg per day is not available, although these
doses have
been used in some patients with advanced disease.
Elderly people
Similar dosing regimens of tamoxifen have been used in the elderly
with
breast cancer and in some of these patients it has been used as sole
therapy.
2.
Anovulatory Infertility
Before commencing any course of treatment, whether initial or
subsequent, the
possibility of pregnancy must be excluded. In women who are
menstruating
regularly, but with anovular cycles, the initial course of treatment
consists of
20mg given daily on the second, third, fourth and fifth days of the
menstrual
cycle. If unsatisfactory basal temperature records or poor
pre-ovulatory
cervical mucus indicate that this initial course of treatment has been
unsuccessful, further courses of treatment may be given during
subsequent
menstrual periods, increasing
