Information about Arimidex (Anastrozole)

Arimidex, with the active ingredient anastrozole, is a non-steroidal aromatase inhibitor primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It reduces estrogen levels in the body, helping to slow or prevent the growth of certain breast tumors that depend on estrogen.

Product Highlights

  • Used to treat early-stage hormone receptor-positive breast cancer in postmenopausal women.
  • First-line treatment of hormone receptor-positive or hormone receptor-unknown advanced or metastatic breast cancer.
  • Used to treat advanced breast cancer that has returned or progressed after treatment with tamoxifen.

Key Ingredient

  • Anastrozole

Key Benefits

  • Lowers estrogen levels to help slow or stop the growth of certain types of breast cancer.
  • Orally administered, making it convenient to use at home.
  • Fewer estrogenic side effects compared to tamoxifen (e.g., no increased risk of uterine cancer).
  • Appropriate for extended use in postmenopausal patients when monitored by a healthcare professional.

Direction of Use

  • Typically taken as 1 mg once daily by mouth.
  • Can be taken with or without food.
  • Take at the same time daily to ensure stable levels of the medication in the body.
  • Do not crush or chew the tablet.
  • Follow your doctor’s instructions strictly and do not adjust the dose without medical advice.

Safety Concerns

  • Can cause bone thinning (osteoporosis) or fractures over long-term use.
  • May lead to hot flashes, joint pain, fatigue, nausea, or mood changes.
  • Liver function abnormalities may occur in rare cases.
  • Cholesterol levels may increase.
  • Requires regular monitoring of bone density and liver function during prolonged use.
  • Use with caution in patients with a history of ischemic heart disease.

Avoid Arimidex (Anastrozole) If

  • You are pregnant or breastfeeding – it can harm the fetus or nursing infant.
  • You have premenopausal hormone status, unless otherwise directed by a specialist.
  • You have a known allergy to anastrozole or any inactive ingredients in the formulation.
  • You are taking estrogen-containing therapies or tamoxifen (may interfere with effectiveness).
