FAQ

Anastrozole is a prescription medicine when purchased from local Canadian pharmacies. Our store policy allows you to place an order without a prescription and have it sent by mail. Treatment with anastrozole should be directed by a qualified health-care professional.

A short-term pill organizer may be practical, but keep the tablets dry, protected from light, and clearly identified. Retaining tablets in their original packaging is preferable when possible because it preserves the label, expiry information, and packaging protection. Do not use a pill organizer if the package instructions require the tablets to remain in their original blister.

The manufacturer of the specific pack cannot be confirmed before supply and may vary. Check the manufacturer's name on the package label when it arrives, along with the active ingredient, 1 mg strength, dosage form, lot number, and expiry date.

No. Anastrozole is contraindicated during pregnancy because lowering estrogen can harm fetal development. It is also contraindicated while breastfeeding because of the potential for serious adverse effects in a nursing infant.

Anastrozole is an aromatase inhibitor used to treat hormone receptor-positive breast cancer in postmenopausal women. It may be used as treatment after surgery for early breast cancer or for locally advanced or metastatic breast cancer, including disease that has 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. 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.

Asked by Danielle, Kelowna, Canada

My package arrived in Kelowna after a very cold spell. What should I check before taking the tablets?

Answered by Support team

Check that the outer package and tablet packaging are intact and that the tablets have no visible damage or unusual appearance. Store anastrozole at 20°C to 25°C; excursions between 15°C and 30°C are permitted, but the actual temperature and duration of cold exposure are unknown. Do not use tablets if the packaging or tablets appear compromised.

Asked by Sophie, St. Johns, Canada

A few tablets in my pack look discoloured compared with the others. Should I still take them?

Answered by Support team

Do not take tablets that have changed colour, texture, or appearance until the product has been checked. Keep the package so the active ingredient, strength, lot number, expiry date, and any tablet imprint can be compared with the label.

Asked by Priya, Barrie, Canada

I have noticed blurred vision since starting anastrozole. Could the medicine be causing it?
