What is anastrozole and how does it work?
Anastrozole is a nonsteroidal aromatase inhibitor, a type of hormonal (endocrine) therapy. It is the generic form of Arimidex. It is FDA-approved for postmenopausal women with hormone receptor-positive early breast cancer as an added (adjuvant) treatment, often alongside surgery or radiation; as a first-line treatment for hormone receptor-positive or hormone receptor-unknown locally advanced or metastatic breast cancer; and for advanced breast cancer that has progressed after tamoxifen.
Many breast cancers grow in response to the hormone estrogen. Anastrozole works by lowering the amount of estrogen the body produces, which can slow or stop the growth of these cancers. It is only appropriate for postmenopausal women; it offers no benefit and may cause harm in premenopausal patients. This information is educational and not medical advice, so always follow the guidance of your own oncologist or prescriber.
How much does anastrozole cost without insurance?
As a generic, anastrozole is already one of the more affordable hormonal breast cancer therapies, which is why so many people choose it over the brand-name Arimidex. But the cash price without insurance is not the same everywhere. Two pharmacies on the same street can charge noticeably different amounts for the exact same tablet, so comparing prices genuinely matters.
Rx.com compares anastrozole prices across more than 60,000 pharmacies and gives you a free discount coupon to use whether or not you have insurance. Prices change often and are shown live, so enter your ZIP above to see today's price at pharmacies near you. The coupon is free to use and there is no membership required.
Anastrozole vs. Arimidex and other alternatives
Anastrozole and Arimidex contain the same active ingredient and work the same way; the generic simply costs less. If your prescription is written for the brand, ask your prescriber or pharmacist whether the generic is an option for you.
Other hormonal therapies your doctor may consider include letrozole and exemestane, which are also aromatase inhibitors, and tamoxifen, which works differently by blocking estrogen's effect on breast tissue rather than lowering estrogen production. Which medication is right depends on your specific situation, menopausal status, and treatment history, so this is a decision to make with your oncologist. Whichever one you are prescribed, you can compare its price on Rx.com.
Anastrozole safety and side effects
Anastrozole has no boxed warning, but it does carry important risks to be aware of. Common side effects include hot flashes, joint and bone pain (arthralgia), fatigue, and nausea. Over time it can lower bone mineral density, which raises the risk of osteoporosis and fractures, and it can increase cholesterol levels. In women with pre-existing ischemic heart disease, a higher rate of cardiovascular events has been observed. Rare but serious reactions include severe skin reactions (lesions, ulcers, or blisters), angioedema or anaphylaxis, and effects on the liver.
Anastrozole is contraindicated in pregnancy and can harm a developing baby; it is not for premenopausal women or for use during pregnancy or breastfeeding. Tell your doctor about all your health conditions and medications before starting. This is a summary, not medical advice, so talk with your provider about any side effects or concerns you have.
