Anastrozole works by inhibiting an enzyme in the body called aromatase. This enzyme is responsible for converting androgens (male hormones) into estrogens.

About Anastrozole

Anastrozole 1 mg is a trusted and widely prescribed medication primarily used to treat hormone-dependent breast cancer in postmenopausal women. It belongs to the class of aromatase inhibitors, designed to lower estrogen levels in the body. Because some breast cancers rely on estrogen to grow, anastrozole helps slow or even stop their progression.

This medication is usually taken long-term and plays a vital role in preventing recurrence after surgery, radiation therapy, or chemotherapy. It is available under the brand name Arimidex and as a generic. Because of its effectiveness and generally well-tolerated side effects, anastrozole has become a mainstay of treatment and prevention strategies for hormone-dependent breast cancer.

How Anastrozole Works

Anastrozole works by inhibiting an enzyme in the body called aromatase. This enzyme is responsible for converting androgens (male hormones) into estrogens. In postmenopausal women, this conversion is the body's primary mechanism for estrogen production. By blocking aromatase activity, anastrozole significantly reduces estrogen production.

With lower levels of circulating estrogen, hormone receptor-positive cancer cells are deprived of the hormone they need to grow and multiply. This helps control the spread of cancer and prevent recurrence after initial treatment. Other drugs in the same class include letrozole and exemestane, but anastrozole remains one of the most frequently prescribed options due to its favorable balance of efficacy and tolerability.

How to Take Anastrozole

Anastrozole should be taken orally with a glass of water, at the same time every day. It can be taken before or after meals, as food does not affect its absorption. Establishing a routine helps maintain stable hormone suppression and makes it easier to adhere to the treatment.

If you miss a Anastrozole dosage, take it as soon as you remember, unless it is almost time for your next dose. Never double the dose to make up for a missed one. Patients should also inform their doctor about all other medications, dietary supplements, or herbal products they are using, as some may interfere with the effectiveness of anastrozole.

It is important to store the medication correctly at room temperature, away from moisture and heat. Regular and careful use is essential to achieve the desired results with minimal side effects.

What happens when anastrozole treatment is stopped?

Treatment with anastrozole should not be stopped abruptly without consulting a doctor. Prematurely stopping treatment can increase the risk of breast cancer recurrence, especially in the first few years after surgery or treatment.

Once treatment is finished, some protective effects persist for years. Studies such as the IBIS-II trial have shown that women who took anastrozole for five years maintained their protection for more than 10 years after stopping treatment.

Some Side effects of Anastrozole in males , such as hot flashes or fatigue, usually disappear within a few weeks of stopping anastrozole. Others, such as changes in bone or cholesterol levels, may take longer to normalize.

Uses of Anastrozole

Anastrozole is primarily prescribed to treat hormone receptor-positive breast cancer, both early and advanced. Doctors often recommend it as adjuvant therapy after surgery or chemotherapy to reduce the risk of recurrence. It can also be used as a first-line treatment for metastatic breast cancer in postmenopausal women.

In addition, anastrozole has demonstrated its effectiveness in preventing breast cancer in women at high risk due to genetic factors or a family history of the disease. Clinical studies support its preventive use, as it effectively reduces estrogen levels that can promote cancer development.

What to Expect During Treatment?

At the start of anastrozole treatment, most patients experience gradual changes rather than immediate effects. During the first few weeks, it's normal to experience side effects such as hot flashes, fatigue, or mild joint pain. Anastrozole pill symptoms occur as your body adjusts to the sudden drop in estrogen levels.

Over time, many of these symptoms lessen or become easier to manage. Regular medical checkups are essential during treatment to monitor your progress.

Anastrozole Dosage

The standard recommended dose of anastrozole is 1 mg daily, in a single tablet. It can be taken with or without food, but regularity is essential: it should be taken at the same time every day to maintain stable concentrations in the body.

In women with early-stage breast cancer, treatment typically lasts five years. However, in cases of lymph node involvement or a higher risk of recurrence, treatment may be extended to ten years. It is very important to adhere to the prescribed dosage and duration, as prematurely discontinuing treatment can reduce its effectiveness.

Anastrozole Price

Anastrozole price varies depending on whether it is a brand-name or generic medication, the provider, and the duration of treatment. Generic medications are more affordable and offer the same effectiveness.

Health insurance coverage and health programs can also influence the final cost. Since most treatments require several months, or even years, of continuous medication, finding a reliable and affordable source like Steroidsstores can make all the difference for patients undergoing prolonged treatment.
