1. WHAT MESTANE IS AND WHAT IT IS USED FOR

Your medicine is called Mestane. Mestane belongs to a class of medicines known as aromatase inhibitors. These drugs act by interfering with a substance called aromatase, which is required for the production of female sex hormones, the estrogens, particularly in postmenopausal women. Reducing estrogen levels in the body is a way of treating hormone-dependent breast cancer.

Mestane is used to treat early-stage hormone-dependent breast cancer in postmenopausal women who have completed 2–3 years of therapy with the medicine tamoxifen.

Mestane is also used to treat advanced hormone-dependent breast cancer in postmenopausal women when hormonal therapy with another medicine has not been sufficiently effective.

2. WHAT YOU NEED TO KNOW BEFORE TAKING MESTANE

Do not take Mestane

  • If you are allergic or have previously been allergic to exemestane (the active substance in Mestane) or to any of the other ingredients of this medicine (listed in section 6).
  • If you are not yet postmenopausal, i.e. if you still have regular menstrual cycles.
  • If you are pregnant, think you might be pregnant, or are breastfeeding.

Warnings and precautions

  • Before starting treatment with Mestane, your doctor may request blood tests to confirm that you have reached menopause.
  • Routine checks of your vitamin D levels may also be performed before treatment begins, as these levels can be very low in early stages of breast cancer. If your vitamin D levels are below normal, you will be given a vitamin D supplement.
  • Before taking Mestane, inform your doctor if you have liver or kidney problems.
  • Inform your doctor if you have had or currently have any condition affecting bone strength. Your doctor may consider it necessary to measure your bone mineral density before and during treatment with Mestane. This is because medicines in this class reduce levels of female hormones, which may lead to loss of bone mineral content and weakened bones.
