1. What Exemestane is and what it is used for

Exemestane belongs to a group of medicines known as aromatase inhibitors. Aromatase Inhibitors interfere with a substance called aromatase, which is needed to produce the female sex hormones, called oestrogens, especially in postmenopausal women. Reduction in oestrogen levels in the body is a way of treating hormone dependent breast cancer.

Exemestane is used

  • to treat hormone dependent early breast cancer in postmenopausal women after they have completed 2-3 years of treatment with the medicine tamoxifen
  • to treat hormone dependent advanced breast cancer in postmenopausal women when a different hormonal drug treatment has not worked well enough.

2. What you need to know before you take Exemestane

Do not take Exemestane

  • if you are allergic (hypersensitive) to exemestane or any of the other ingredients of this medicine (listed in section 6).
  • if you have not already been through 'the menopause', i.e. you are still having your monthly period,
  • if you are pregnant, or are likely to be pregnant
  • if you are breast-feeding.

Warnings and precautions

Before treatment with Exemestane, your doctor may want to take blood samples to make sure you have reached the menopause.

Before treatment, your Vitamin D level maybe routinely checked as in the early stages of breast cancer this may be very low. If your levels are lower than normal, you will be given a Vitamin D supplement.

Talk to your doctor or pharmacist before taking Exemestane:

  • if you have problems with your liver or kidneys.
  • if you have a history or are suffering from any condition which affects the strength of your bones (e.g. osteoprosis). Your doctor may want to measure your bone density before and during the treatment with Exemestane. This is because drugs of this class lower the levels of female hormones and this may lead to a loss of the mineral content of bones, which might decrease their strength. Your doctor may give you medicine to prevent or treat bone loss.

Please tell your doctor if one of these conditions applies to you.

Exemestane is not suitable for use in children and adolescents.
