What are exemestane tablets?

Exemestane tablets are used in women who are past menopause for the treatment of:

  • Early breast cancer (cancer that has not spread outside the breast) in women who:
    • have cancer that needs the female hormone estrogen to grow, and
    • have had other treatments for breast cancer, and
    • have taken tamoxifen for 2 to 3 years, and
    • are switching to exemestane tablets to complete 5 years in a row of hormonal therapy.
  • Advanced breast cancer (cancer that has spread) after treatment with tamoxifen, and it did not work or is no longer working.

It is not known if exemestane tablets are safe and effective in children.

Do not take exemestane tablets if you

are allergic to exemestane tablets or any of the ingredients in exemestane tablets.

Before you take exemestane tablets, tell your doctor about all your medical conditions, including if you:

Tell your doctor about all the medicines you take,

including prescription and over-the-counter medicines, vitamins and herbal supplements. Especially tell your doctor if you take medicines that contain estrogen, including other hormone replacement therapy or birth control pills or patches. Exemestane tablets should not be taken with medicines that contain estrogen as they could affect how well exemestane tablets work.
