EVERDEX belongs to a group of medicines called aromatase inhibitors. This means that it interferes with some of the actions of aromatase, an enzyme within the body which effects the level of certain female sex hormones such as oestrogens. EVERDEX is used to treat breast cancer in post-menopausal women.
1. What EVERDEX is and what it is used for
2. What you need to know before you take EVERDEX
Do not take EVERDEX:
- if you are hypersensitive (allergic) to anastrozole or any of the other ingredients of EVERDEX (listed in section 6).

Warnings and precautions
Take special care with EVERDEX:
- If you are suffering from any disorder or disease which affects your heart, liver or kidneys. Please inform your doctor.
- EVERDEX is not recommended if you are pre-menopausal and it should not be given to children.
Special warning
EVERDEX lowers the level of female hormones and this may lead to a loss of the mineral content of bones which might decrease their strength and as a possible consequence the risk of fractures may increase. This possible increased risk should be managed according to treatment guidelines for managing bone health in post-menopausal women. Women are encouraged to discuss this possible risk and treatment options with their medical practitioners.
