What is Aromasin used for?

Aromasin is used to treat advanced breast cancer in postmenopausal women whose disease has gotten worse after treatment with tamoxifen.  Postmenopausal women are women who have gone through the  “change of life” and are no longer having menstrual cycles.

Aromasin is used to reduce the risk of breast cancer recurrence (coming back) in postmenopausal women with estrogen receptor positive early stage breast cancer who have received two to three years of tamoxifen and are switched to Aromasin to complete a total of five consecutive years of therapy.

The safety and effectiveness of Aromasin in women who can still have children (premenopausal) has not been determined.

General Precautions with Aromasin: 

Do not take Aromasin if you are pregnant. Aromasin may cause birth defects or even death to an unborn baby. Aromasin has only been studied in postmenopausal women.

Tell your doctor if you have a history of liver or kidney problems.

What should I tell my doctor or healthcare provider?

Because certain other medications can interact with Aromasin, review all medications that you are taking with your healthcare provider, including those that you take without a prescription. It is important to avoid taking any medications containing estrogen along with Aromasin, because they may interfere with the action of Aromasin.

If you are breastfeeding and are accidentally exposed to Aromasin tell your doctor right away.
