Arimidex (Anastrozole) — Important Information

Arimidex 1 mg contains anastrozole, an aromatase inhibitor used as hormone therapy for certain types of breast cancer. It works by reducing the amount of estrogen produced by the body, which can slow or stop the growth of breast cancer cells that depend on estrogen. Anastrozole is primarily used in women who have gone through menopause.

Product Overview

Arimidex 1 mg is a prescription medicine containing anastrozole. It belongs to a group of medicines called aromatase inhibitors. Some breast cancers are hormone receptor-positive, meaning that estrogen can contribute to the growth of cancer cells. After menopause, much of the body's estrogen is produced through the conversion of other hormones in tissues such as fat. Anastrozole reduces this estrogen production. Depending on the individual's cancer and treatment plan, anastrozole may be used after surgery or other treatment for early breast cancer, as an initial treatment for certain advanced breast cancers, or when breast cancer has progressed following tamoxifen treatment.

Uses & Medical Information

Arimidex (anastrozole) may be prescribed for: Adjuvant treatment of certain hormone receptor-positive early breast cancers in postmenopausal women Initial hormone treatment for certain locally advanced or metastatic breast cancers Advanced breast cancer that has progressed following treatment with tamoxifen In some circumstances, prevention of breast cancer in women at increased risk may be discussed with a healthcare professional The appropriate use depends on the type and stage of cancer, hormone-receptor status, menopausal status, previous treatment, and the patient's overall health.

How It Works

Anastrozole blocks an enzyme called aromatase. Aromatase helps the body produce estrogen. By inhibiting this enzyme, anastrozole lowers estrogen levels. For breast cancers that depend on estrogen for growth, reducing estrogen can help slow or stop the growth of cancer cells. Because hormone therapy works differently from chemotherapy, whether anastrozole is appropriate depends on the characteristics of the individual cancer.

Important Safety Information

rimidex should be used under the supervision of a healthcare professional experienced in treating breast cancer.

Your healthcare professional may recommend monitoring bone health during treatment. It may also increase cholesterol levels. Patients with pre-existing ischemic heart disease should discuss the potential cardiovascular risks and benefits of anastrozole with their doctor. Seek prompt medical attention for symptoms such as difficulty breathing or swallowing, significant swelling, severe rash, chest pain, or yellowing of the skin or eyes. Pregnancy and Breastfeeding Anastrozole can cause harm to a developing fetus and is not intended for use during pregnancy. It is primarily prescribed to women who have gone through menopause. Tell your healthcare professional if you are pregnant, think you may be pregnant, or are breastfeeding before taking anastrozole. Drug Interactions Tell your doctor and pharmacist about all prescription medicines, over-the-counter medicines, vitamins, and supplements you take. In particular, discuss estrogen-containing medicines, hormone replacement therapy, hormonal contraceptives, raloxifene, and tamoxifen. Tamoxifen and estrogen-containing treatments can interfere with the intended action of anastrozole and require medical consideration.
