Anastrozole 1mg (Arimidex) – 30 Tablets

Anastrozole 1mg, marketed under the brand name Arimidex, is a prescription aromatase inhibitor used for certain types of breast cancer in postmenopausal women. It works by reducing the body's production of estrogen, which can help slow the growth of hormone-sensitive breast cancer cells.

Why Is Anastrozole 1mg Prescribed?

Some breast cancer cells depend on estrogen signals to grow. Anastrozole blocks an enzyme called aromatase, which is involved in estrogen production after menopause. By lowering estrogen levels, anastrozole helps reduce the hormonal stimulation of certain breast cancer cells.

Anastrozole is clinically established for use in appropriate postmenopausal patients and is generally taken once daily according to the prescribing information.

What Is Anastrozole Used For?

Anastrozole is indicated for certain breast cancer situations, including:

• Adjuvant treatment of postmenopausal women with hormone receptor-positive early breast cancer
• First-line treatment of certain locally advanced or metastatic breast cancers in postmenopausal women
• Treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy

The specific treatment plan depends on the patient's diagnosis, menopausal status, previous treatment, and medical history.

How Does Anastrozole Work?

After menopause, an important source of estrogen comes from the conversion of other hormones through an enzyme called aromatase.

Anastrozole inhibits aromatase → estrogen production decreases → estrogen-dependent cancer cells receive less hormonal stimulation.

This is why anastrozole is classified as an aromatase inhibitor.

Dosage & How to Take Anastrozole

The labeled dose is generally:

• One 1mg tablet once daily
• Take it at approximately the same time each day.
• It may be taken with or without food.
• Follow the dosage and treatment duration prescribed by your doctor.
• Do not change the dose or stop treatment without medical advice.

Possible Side Effects

Like other prescription medicines, anastrozole can cause side effects. Commonly reported effects include:

• Hot flashes
• Joint or muscle pain
• Weakness or fatigue
• Headache
• Nausea
• Bone or back pain
• Insomnia
• Rash
• Bone loss or osteoporosis
• Increased risk of fractures

The prescribing information also warns that cholesterol levels may increase and that bone mineral density can decrease during treatment.

Warnings & Precautions

Tell your doctor before using anastrozole if you have:

• Low bone density or osteoporosis
• A history of heart disease
• High cholesterol
• Liver problems
• Allergies to anastrozole or any of its ingredients

Anastrozole can reduce bone mineral density, so your healthcare professional may recommend monitoring bone health during longer-term treatment. Patients with pre-existing ischemic heart disease may also require particular consideration of cardiovascular risks.

Anastrozole is not intended for premenopausal women unless specifically prescribed as part of an appropriate medical treatment plan, and it may cause fetal harm. Pregnancy and breastfeeding require specific medical guidance.

Drug Interactions

Tell your doctor or pharmacist about all medicines and supplements you use. In particular, discuss any estrogen-containing medicines or hormone replacement therapy, as these may interfere with the intended estrogen-lowering effect of anastrozole.

Never start, stop, or combine prescription medicines without professional medical advice.

Storage

• Store at room temperature.
• Keep the tablets in their original packaging when possible.
• Protect from excessive heat and moisture.
• Keep out of reach of children.
