Arimidex® 1mg Tablets (Anastrozole) – Hormone Therapy (Rx)

Quick answer: Arimidex 1mg (anastrozole) is a hormone therapy tablet for women who have been through menopause and have hormone receptor-positive breast cancer. It lowers oestrogen levels so the cancer has less fuel to grow. You take it by mouth at home. MedHub supplies it on prescription with delivery across Pakistan.

For patients and families

What is Arimidex 1mg?

Arimidex 1mg is AstraZeneca’s brand of anastrozole, a film-coated tablet from a group of medicines called aromatase inhibitors. After menopause, the ovaries stop making most oestrogen, but the body still produces some in fat and other tissues using an enzyme called aromatase. Anastrozole blocks that enzyme. Many breast cancers need oestrogen to grow, so cutting the supply slows or stops them.

What is it used for?

Doctors prescribe anastrozole for postmenopausal women with hormone receptor-positive breast cancer:

• Early breast cancer: after surgery, to reduce the chance of the cancer coming back. Some women start it after two to three years of tamoxifen.
• Advanced breast cancer: as first treatment, or when the cancer grows despite tamoxifen.

It does not work on its own in women who still have periods, because their ovaries keep making oestrogen. Your oncologist checks your menopausal status first.

How is it taken?

You swallow Arimidex 1mg whole with water, with or without food. Your doctor or pharmacist explains how to take it, and a fixed daily routine helps you remember. Your doctor decides how long you stay on it, which in early breast cancer is often several years. Do not take oestrogen-containing medicines, such as hormone replacement therapy, alongside it.

Common side effects

• Hot flushes and sweating
• Joint pain or stiffness, especially in the hands and knees
• Tiredness, headache and low mood
• Nausea and mild skin rash
• Thinning of the bones over time

See your doctor straight away if you get a severe skin reaction, swelling of the face or throat, yellowing of the skin, or tingling and pain in the hand that wakes you at night.
