Arimidex (anastrozole) is an aromatase inhibitor used to treat hormone-receptor-positive breast cancer in postmenopausal women. It works by reducing the amount of estrogen your body produces, thus slowing or stopping the growth of cancer cells that depend on estrogen for survival. It’s frequently prescribed as adjuvant therapy (following surgery or other treatments) or as first-line treatment for advanced breast cancer.
Common Side Effects
- Hot flashes: Manage these with lifestyle adjustments (dress in layers, use a fan) or discuss options like hormone replacement therapy with your doctor. Joint pain: Regular low-impact exercise, like walking or swimming, can help. Your doctor might suggest medication for pain management. Osteoporosis risk: Regular weight-bearing exercise and calcium/vitamin D supplements can help mitigate this risk. Discuss bone density testing with your doctor.
Less Frequent but Important Side Effects
Less common side effects include nausea, fatigue, and skin rashes. Report any concerning side effects to your medical team immediately.
Monitoring Your Treatment
Regular blood tests and check-ups are crucial to monitor your response to Arimidex and identify any potential problems early. Follow your doctor’s recommendations for appointments and testing.
