FAQ

A prescription is required to buy anastrozole from local pharmacies in Australia, where it is a Schedule 4 prescription-only medicine. Our store policy allows you to order it without a prescription and have it sent by mail. A prescription remains important for ensuring this treatment is appropriate and monitored.

Most people can drive while taking anastrozole, but weakness or sleepiness can occur. Do not drive, operate machinery or do tasks requiring alertness if you feel drowsy, weak or otherwise affected by the tablets. See how you respond before driving.

Not necessarily. Tablet colour, shape, size, coating, imprint and packaging can differ between anastrozole products and may also change between supplies. The important identifiers are the active ingredient, 1 mg strength and film-coated tablet dosage form shown on the package label.

Anastrozole is an aromatase inhibitor used to treat hormone-responsive breast cancer in postmenopausal women. It may be used for early breast cancer after primary treatment, or for locally advanced or metastatic disease. It is also used when advanced breast cancer progresses after tamoxifen treatment.

The usual adult regimen for its established breast cancer uses is one 1 mg film-coated tablet by mouth once daily. It can be taken with or without food, preferably at about the same time each day. Swallow the tablet with water and follow the treatment plan set by the prescriber.

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.

Storage

Arimidex should be stored at room temperature. Protect from moisture, direct heat, and light. Do not store in the bathroom or near a sink. Keep Arimidex out of the reach of children and away from animals.

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 Kylie, Cairns, Australia

My parcel arrived in Cairns after a very hot day and the box felt warm. What should I check before I take the tablets?

Answered by Support team

Keep the package and check the label, blister pockets and tablets for damage, moisture, discolouration or crumbling. Anastrozole should be stored at 20°C to 25°C, with excursions from 15°C to 30°C allowed; because the actual temperature and duration are unknown, do not use tablets that appear compromised until the issue is checked.

Asked by Megan, Geelong, Australia

I'm in Geelong. Can I enter my postcode before paying to check whether this medicine can be delivered to my address?

Answered by Support team

Yes. Enter your Geelong postcode during checkout to check whether delivery is available for your address before payment. Availability can vary by destination.

Asked by Tahlia, Alice Springs, Australia

I live in Alice Springs, outside the major cities. How can I find out whether you can deliver anastrozole to my area before I order?

Answered by Support team

Enter your Alice Springs address and postcode at checkout to check delivery availability before placing the order. We cannot confirm remote-area eligibility until the destination details are entered.

Asked by Sophie, Toowoomba, Australia

My pack arrived without a patient leaflet. What should I do before starting the tablets?

Answered by Support team

Check the outer pack and blister label for the active ingredient, 1 mg strength, dosage form, batch number and expiry date. If you need instructions or cannot verify those details, ask a pharmacist or prescriber before taking the tablets rather than relying on an unidentified product.

Asked by Rebecca, Perth, Australia

Since starting anastrozole I've been waking several times overnight. Can the medicine affect sleep?

Answered by Support team
Medical reviewed by John Buducci

Sleep problems, including insomnia, have been reported with anastrozole, although other causes are also common. If the sleep disruption is persistent, severe or affecting daily functioning, discuss it with the clinician managing your treatment rather than changing the dose yourself.
