What is Arimidex used for?
As women get older, they will eventually go through the menopause.
At this stage, Arimidex can be given to bring down the estrogen levels in your body making it less likely that breast tumors will form. It can also be used if you have already been diagnosed with breast cancer or if other medication has not worked.
Usually the other treatment medication for this condition is tamoxifen, a medication that is meant solely for women, so men and children should not use it.

Arimidex FAQs
Can I take this with food?
Arimidex can be taken with or without food.
Can I take this if I am pregnant?
Arimidex may cause fetal harm. Arimidex is not for use in premenopausal women; therefore, if you become pregnant, you should stop taking Arimidex and immediately contact their doctor.
Can I take this if I am pregnant?
It is not known if anastrozole is excreted in human milk. Because many drugs are excreted in human milk and because of the tumorigenicity shown for anastrozole in animal studies, or the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
How quickly does Arimidex lower estrogen?
The recommended daily dose, Arimidex 1 mg, reduced estradiol by approximately 70% within 24 hours and by approximately 80% after 14 days of daily dosing. Suppression of serum estradiol was maintained for up to 6 days after cessation of daily dosing with Arimidex 1 mg.
Does Arimidex compromise the immune system?
Hormone therapies, including tamoxifen, letrozole, anastrozole, exemestane and goserelin, do not affect your risk of getting coronavirus or of becoming seriously ill if you do get it. Taking hormone therapy does not affect your immune system.
