FAQ

Anastrozole is a Prescription Only Medicine and requires a prescription when bought from local UK pharmacies. Our store policy allows you to order it without a prescription and have it sent by mail. As this is a cancer medicine, treatment should be directed by a clinician.

A pill organiser may be suitable for a short period if it is clean, dry and kept away from light, but the original blister and carton provide the best protection and retain the medicine identification. Keep enough packaging to check the product name, strength, batch number and expiry date, and follow any packaging instructions on the pack received.

The exact manufacturer for an individual order is not guaranteed and may vary with available supply. Check the manufacturer's name on the outer carton and blister pack when it arrives; a familiar name such as Arimidex or Anastrozole Accord is not promised for every order.

No. Anastrozole is contraindicated during pregnancy because reducing oestrogen can harm fetal development. It is also contraindicated while breastfeeding because of the potential for serious effects in a breastfed child.

Anastrozole is an aromatase inhibitor used for certain hormone receptor-positive breast cancers in postmenopausal women. It may be used as adjuvant treatment for early breast cancer or for locally advanced or metastatic disease, including some cases that have progressed after tamoxifen.

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.

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.

Asked by Harriet Collins, Glasgow, United Kingdom

I previously took Arimidex and need to avoid certain tablet ingredients. Will this product have the same inactive ingredients as my old brand?

That cannot be guaranteed, as inactive ingredients can differ between brands and manufacturers. Please check the ingredient list on the received carton or leaflet before use if you have an intolerance or known allergy.

Asked by Margaret Evans, Reading, United Kingdom

I have type 2 diabetes and have been prescribed anastrozole for breast cancer. Is diabetes a problem with this medicine?

Answered by Support team
Medical reviewed by Wendy Hayes

Diabetes is not a specific contraindication to anastrozole, and no diabetes-specific dose adjustment is generally required. Continue your usual diabetes monitoring, as your wider cancer treatment and health circumstances may affect your care plan.
