What is AROMASIN?

AROMASIN is 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 AROMASIN 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 AROMASIN is safe and effective in children.

Do not take AROMASIN if you are allergic to AROMASIN or any of the ingredients in AROMASIN. See the end of this leaflet for a complete list of ingredients in AROMASIN.

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

  • are still having menstrual periods (are not past menopause). AROMASIN is only for women who are past menopause.
  • have weak or brittle bones (osteoporosis)
  • are pregnant or plan to become pregnant. Taking AROMASIN during pregnancy or within 1 month of becoming pregnant can harm your unborn baby.
    • Females who are able to become pregnant should have a pregnancy test within 7 days before starting treatment with AROMASIN.
    • Females who are able to become pregnant should use effective birth control (contraceptive) during treatment with AROMASIN and for 1 month after your last dose of AROMASIN. Tell your doctor right away if you become pregnant or think you may be pregnant.
  • are breastfeeding or plan to breastfeed. It is not known if AROMASIN passes into your breast milk. Do not breast-feed during treatment with AROMASIN and for 1 month after your last dose of AROMASIN.
  • Have liver or kidney problems.

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. AROMASIN should not be taken with medicines that contain estrogen as they could affect how well AROMASIN works.

How should I take AROMASIN?

  • Take AROMASIN exactly as your doctor tells you.
  • Take AROMASIN 1 time each day after a meal.
  • If you take too much AROMASIN, call your doctor right away or go to nearest hospital emergency room.

What are the possible side effects of AROMASIN?

AROMASIN may cause serious side effects, including:

  • Bone loss. AROMASIN decreases the amount of estrogen in your body which may reduce your bone mineral density (BMD) over time. This may increase your risk for bone fractures or weak and brittle bones (osteoporosis). Your doctor may check your bones during treatment with AROMASIN if you have osteoporosis or at risk for osteoporosis.

The most common side effects of AROMASIN in women with early breast cancer include:

  • hot flashes
  • headache
  • feeling tired
  • trouble sleeping
  • joint pain
  • increased sweating

The most common side effects of AROMASIN in women with advanced breast cancer include:

  • hot flashes
  • increased sweating
  • nausea
  • increased appetite
  • feeling tired

Your doctor will do blood tests to check your vitamin D level before starting treatment with AROMASIN.

AROMASIN may cause decreased fertility in males and females. Talk to your doctor if you have concerns about fertility.

These are not all the possible side effects of AROMASIN. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

How should I store AROMASIN?
