What FARESTON is used for

FARESTON is used to treat hormone-sensitive breast cancer in women who have had their menopause.

It belongs to the group of medicines known as anti-oestrogens. It helps to stop the tumour cells from growing and multiplying.

A doctor's prescription is required for FARESTON.

Your doctor, however, may prescribe FARESTON for another purpose.

Ask your doctor if you have any questions about why FARESTON has been prescribed for you.

Before you take FARESTON

When you must not take it

Do not take FARESTON if:

  • you have endometrial hyperplasia (an overgrowth in the lining of the uterus)
  • you have severe liver failure
  • you are pregnant or breastfeeding
  • you have a heart condition called QT prolongation, where the heart muscle takes longer to contract and then recover due to a disorder involving electrical impulses.
  • you have other heart conditions including bradycardia (slow heart rhythm), symptomatic arrhythmias (irregular heart rhythm) or heart failure.
  • you have electrolyte disturbances including uncorrected hypokalaemia (low blood potassium levels; which can in turn cause heart arrhythmia disorders).

FARESTON is for use by women who have had their menopause and should not be used by pregnant or breastfeeding women.

Do not take FARESTON after the expiry date (EXP) printed on the pack.

Do not take FARESTON if the packaging is torn or shows sign of tampering.

If you are not sure if you should start taking FARESTON, contact your doctor or pharmacist.

  • any other medicines
  • any other substances such as foods, preservatives or dyes
  1. you have angina or a heart condition, including an irregular heart beat
  2. you feel pain in your bones
  3. you have had problems with blood clots in the past
    In severe cases, FARESTON is not recommended.
  4. you have liver problems
  5. you have any other medical conditions or health problems

If you have not told your doctor about any of the above, report them before you take any FARESTON.
