Description
Anastrozole 1 mg Tablets – Hormone Therapy for Breast Cancer
Anastrozole 1 mg is a prescription oral medication used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which reduce estrogen levels in the body—a hormone that can promote the growth of certain types of breast cancer.
Key Features & Benefits:
- Effective as first-line treatment for postmenopausal women with HR+ breast cancer
- Helps reduce the risk of cancer recurrence after surgery or radiation
- Well-tolerated oral once-daily medication
- Non-chemotherapy hormone therapy with fewer systemic effects
- Can be used in advanced or metastatic settings
How It Works:
Anastrozole inhibits the aromatase enzyme, which is responsible for converting androgens into estrogen. Lowering estrogen levels helps slow or stop the growth of estrogen-dependent breast tumors.
Dosage & Administration:
Typical dosage is 1 mg once daily, taken with or without food. Always follow your oncologist’s prescription. Do not stop the medication unless instructed by your doctor, even if you feel well.
Precautions:
- Not for use in premenopausal women or men unless specifically prescribed
- May lead to bone thinning—regular bone density tests recommended
- Inform your doctor if you have liver issues, osteoporosis, or heart conditions
- Avoid using with estrogen-containing medications
Storage:
Store in a cool, dry place below 30°C. Keep away from children and direct sunlight.

Frequently Asked Questions (FAQs)
1. What is Anastrozole 1 mg used for?
It is used to treat hormone receptor-positive breast cancer in postmenopausal women, either as initial therapy or following surgery/radiation.
2. How does Anastrozole differ from Tamoxifen?
While both are hormone therapies, Anastrozole lowers estrogen production (via aromatase inhibition), while Tamoxifen blocks estrogen receptors. Anastrozole is typically used in postmenopausal women.
3. Are there side effects?
Common side effects include joint pain, hot flashes, fatigue, and bone thinning. Report unusual symptoms such as chest pain or shortness of breath to your doctor immediately.
4. Can men use Anastrozole?
In rare cases, it may be prescribed off-label for conditions like gynecomastia or certain cancers in men—but only under specialist supervision.
5. How long should I take Anastrozole?
Treatment duration varies but often continues for 5 years or longer depending on cancer type, stage, and recurrence risk. Follow your oncologist’s plan closely.
6. Can I take vitamins or supplements with Anastrozole?
Some supplements may interact. Calcium and vitamin D are commonly prescribed alongside to support bone health. Always inform your doctor about all supplements you use.
7. Is Anastrozole a chemotherapy drug?
No. Anastrozole is a hormone therapy, not a cytotoxic chemotherapy. It has a different mechanism and generally causes fewer severe side effects.
