FAQ

Anastrozole is a prescription-only medicine at local US pharmacies. Our store policy allows an order to be placed without a prescription and sent by mail, but treatment with anastrozole should be directed by the clinician managing the cancer care.

The available product information confirms a film-coated tablet but does not establish whether this specific tablet may be split, crushed, or chewed. Do not alter the tablet unless the instructions for the received package or a pharmacist specifically confirm that it is appropriate.

The manufacturer and regulatory status of the exact product supplied are not specified, so its individual FDA approval status cannot be confirmed in advance. Arimidex, the US brand of anastrozole, is FDA-approved, but that does not identify or establish the approval status of a particular supplied generic package.

Anastrozole is an aromatase inhibitor used for hormone receptor-positive breast cancer in postmenopausal women. Established uses include adjuvant treatment of early breast cancer and first-line treatment of locally advanced or metastatic disease; it may also be used when advanced cancer progresses after tamoxifen treatment.

Anastrozole is contraindicated during pregnancy because lowering estrogen can harm fetal development. Breastfeeding should be avoided during treatment and for 2 weeks after the last dose because of the potential for serious adverse effects in a breastfed infant.

Description

General Information

Arimidex (Anastrozole) is approved for adjuvant treatment (treatment following surgery with or without radiation) of postmenopausal women with hormone receptor-positive early breast cancer. Your doctor may prescribe this remedy for other purposes. Contact your physician to learn more information.

Don't stop treatment with Arimidex earlier than it was prescribed by your doctor, even if you notice improvements in your condition. Stopping the medication too early may worsen your condition. Be careful about doing dangerous tasks, driving, operating machinery, or climbing until you are aware of how this drug affects you. Don't drink alcohol.

Arimidex is prescribed for postmenopausal women only. Don't take Arimidex if you are pregnant. Birth control measures are recommended during treatment and a month after it.

Be aware that women with a history of ischemic heart disease may have a slight increase in this type of heart disease if they take Arimidex.

Arimidex may be the reason for osteoporosis, increasing the chance of fractures.

The cholesterol level may increase during Arimidex treatment. If you use Arimidex, you may also experience allergies, skin reactions, and changes in blood tests of liver function.

Arimidex is a vital drug for treating hormone receptor-positive breast cancer since it efficiently blocks the synthesis of estrogen, which has a significant effect on patients. Due to its capacity to lower the chance of cancer return and enhance survival rates, it is a mainstay of adjuvant treatment for postmenopausal women diagnosed with breast cancer. Compared to conventional hormonal therapy, its advantageous side effect profile further emphasizes how important it is to provide patients with effective treatment while preserving their quality of life. Arimidex is a significant development in the battle against breast cancer, providing many people with a better prognosis across the globe.

Customer questions

Asked by Customer, El Paso, United States

I live in El Paso, where packages can sit in hot weather. Is this type of anastrozole tablet protected well enough for ordinary transportation?

Answered by Support team

Film-coated tablets can normally travel by mail when appropriately packed and handled. Keep the package in its protective packaging after arrival and check that it is intact; the labeled storage range is 68°F to 77°F, with permitted excursions from 59°F to 86°F.

Asked by Customer, San Jose, United States

When my package arrives, where should I look for the lot number and expiration date?

Answered by Support team

Check the outer carton and the blister or bottle label, as the lot number and expiration date are usually printed there. Compare those details with the package labeling before use; the remaining shelf life of a particular order cannot be confirmed in advance.

Asked by Customer, Denver, United States

I receive my mail at a PO Box in Denver. Can I use that address for an order?

Answered by Support team

Please enter the PO Box address at checkout and use the address options shown there. PO Box acceptance is not confirmed in advance and may depend on the available shipping option.

Asked by Customer, Phoenix, United States

My Arimidex package arrived in Phoenix with a damaged blister seal. Can I still use the tablets?

Answered by Support team

Do not use tablets from a blister or package whose seal or physical condition appears compromised until the issue is checked. Contact customer service within 7 days of delivery; a replacement or refund can be offered depending on your preference.
