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

Exemestane 25 mg film-coated tablets are used to treat hormone dependent early breast cancer in postmenopausal women after they have completed 2-3 years of treatment with the medicine tamoxifen.

Exemestane 25 mg film-coated tablets are also used to treat hormone dependent advanced breast cancer in postmenopausal women when a different hormonal drug treatment has not worked well enough.

Do not take Exemestane:
  • If you are or have previously been allergic to Exemestane (the active ingredient in 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, likely to be pregnant or breastfeeding.

Warnings and precautions
  • Talk to your doctor, pharmacist or nurse before taking Exemestane.
  • Before treatment with Exemestane, your doctor may want to take blood samples to make sure you have reached the menopause;
  • Routine checking of your vitamin D level will also be made before treatment, as your level may be very low in the early stages of breast cancer. You will be given vitamin D supplement if your levels are below normal;
  • Before taking Exemestane, tell your doctor if you have problems with your liver or kidneys;
  • Tell your doctor if you have a history or are suffering from any condition which affects the strength of your bones. Your doctor may want to measure your bone density before and during the treatment of Exemestane. This is because medicines 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.

Other medicines and Exemestane

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines including medicines obtained without a prescription.
