What Nolvadex is and what it is used for
The name of your medicine is Nolvadex. Nolvadex contains a medicine called tamoxifen,
which belongs to a group of medicines called ‘anti-oestrogens’.
Oestrogen is a natural substance in your body known as a ‘sex hormone’. Nolvadex works by
blocking the effects of oestrogen.
Nolvadex is used to treat breast cancer. It can also be used to treat infertility caused by a failure
to ovulate properly.
What you need to know before you take Nolvadex
Do not take Nolvadex:
• If you are pregnant or think you might be pregnant (see the section on ‘Pregnancy’
• If you are allergic to tamoxifen or any of the other ingredients of this medicine (listed
in section 6).
• If you are taking anastrozole.
• If you are taking any treatment for infertility.
• If you have had blood clots in the past and the doctor did not know what caused them.
• If someone in your family has had blood clots with the cause not known.
• If your doctor has told you that you have an illness which runs in the family that
increases the risk of blood clots.

medicines. This includes medicines that you buy without a prescription and herbal medicines.

Pregnancy and breast-feeding
Do not take Nolvadex if you are pregnant. This is because it may affect your unborn baby.

on what contraceptive precautions you should take, as some may be affected by Nolvadex.
