What ANASTROZOLE-GA is used for

ANASTROZOLE-GA is used to treat breast cancer in women after they have undergone menopause.

ANASTROZOLE-GA slows or stops the growth of cancer cells, but it does not kill these cells.

Your doctor can answer any questions that you have about your condition or this medicine.


ANASTROZOLE-GA is an aromatase inhibitor that acts on the body to stop the body producing oestrogen (female sex hormone). Only small quantities of oestrogens are produced in post-menopausal women, which may encourage cancer cells to grow in women with breast cancer.

In pre-menopausal women, the ovaries produce high concentrations of oestrogen. Oestrogen acts to prepare the womb for pregnancy, allow sex drive to develop and make breasts grow.

Before you use ANASTROZOLE-GA

Before you start to use it:

You must tell your doctor if:

  • You have allergies to ANASTROZOLE-GA or any of the other ingredients in this product.
  • You are on any other medicine, including medicine from a chemist, supermarket or health shop that you brought without a prescription.
  • You are taking a medicine containing oestrogen.
  • You have any disease or disorder that involves your kidney or liver.
  • You have osteoporosis, a family history of osteoporosis or risk factors for developing osteoporosis. Examples of risk factors are smoking, low calcium diet, poor mobility, slight build or you are being treated with steroids.

Anastrozole may decrease bone mineral density (BMD) in women who have been through menopause increasing the risk of fractures. Talk to you doctor about management of this possible increased risk.

If you have not told your doctor any of the above things, please tell them before you begin taking ANASTROZOLE-GA.

When you must not take it:

Do not use ANASTROZOLE-GA if you have not yet experienced menopause.

Do not use ANASTROZOLE-GA if you are pregnant or breastfeeding unless your doctor says that it is safe. It is not known if it is safe for you to take ANASTROZOLE-GA while you are pregnant. It may affect your baby if you take it early in pregnancy or in the last weeks before your baby is due.

Do not give ANASTROZOLE-GA to children. There is no data to support the safety of ANASTROZOLE-GA in children.

  • Anastrozole, the active ingredient in ANASTROZOLE-GA tablets.

  • Other anti-oestrogen medicines

Symptoms of an allergic reaction can be shortness of breath, wheezing, difficulty in breathing, swelling of the lips, face, tongue or other parts of the body, rash, itchy skin or hives.

Do not use ANASTROZOLE-GA after the expiry date printed on the pack, or if the packaging is damaged or torn. It may have no effect, or worse, an entirely unexpected effect if you take it after the expiry date.

If you forget to take it:

You should take ANASTROZOLE-GA as prescribed by your doctor. If you miss a dose, do not take an extra dose. Just resume your normal schedule. For example, if you forget to take Monday’s tablet leave the tablet allocated to Monday. Then on Tuesday resume as normal by taking the tablet allocated to Tuesday. Do not take extra tablets to make up for a missed dose.

Try to take your tablet at the same time everyday. This will help you remember.

Ask your doctor or pharmacist for more hints if you have trouble remembering to take ANASTROZOLE-GA.
