Additionally, as anastrozole is a cancer preventative, there will be no proof for a woman taking the drug that it has stopped them from developing breast cancer.

In a news story published on 7 November 2023, NHS England said that around 289,000 women at moderate or high risk of breast cancer could benefit from anastrozole.
Tens of thousands more women at increased risk of breast cancer could now benefit from a proven risk-reducing drug on the NHS, after it was licensed in a new use to help prevent the disease. Women who have a medium or high risk of developing breast cancer because of a family history might have anastrozole. Anastrozole belongs to a group of medicines called ‘aromatase inhibitors’.

While anastrozole has been used as breast cancer medication for years, doctors can now easily prescribe it as a cancer preventative. Anastrozole is a hormone therapy medication that has been used for years in treating breast cancer.
Polygenic risk scores do still have a place in breast cancer screening and prevention strategies
Arimidex should not be used in boys with growth hormone deficiency in addition to growth hormone treatment. In the pivotal clinical trial, efficacy was not demonstrated and safety was not established (see section 5.1). Since anastrozole reduces estradiol levels, Arimidex must not be used in girls with growth hormone deficiency in addition to growth hormone treatment. Long-term safety data in children and adolescents are not available.

The BNF lists hepatotoxicity of Anastrozole as an uncommon adverse reaction i.e. a frequency of 1 in 1000. The mechanism is variable (Table 1) [1-8] and almost all the reported cases had reversible effect with prompt clinical and laboratory improvement. However liver failure worsened in our patient despite its withdrawal. “This is the first drug to be repurposed through a world-leading new programme to help us realise the full potential of existing medicines in new uses to save and improve more lives on the NHS.
Coping with side effects
Anastrozole works by stopping “aromatase”, a chemical that the body uses as part of this process. As anastrozole can have a number of side effects, in the UK GnRH agonists are usually used to stop the production of oestrogen instead. The effects will stop in days if you stop taking the medication. Under the current system, when drugs come off patent and become generic – meaning they can be sold by any manufacturer- there is little financial incentive for pharmaceutical companies to drive new licensing applications.

This fabulously fun mug is designed with breasts of all shapes and sizes in mind and includes a subtle reminder to always ‘check yours’.
Exposure to anastrozole can be increased in subjects with hepatic impairment (see section 5.2); administration of Arimidex in patients with moderate and severe hepatic impairment should be performed with caution (see section 4.2). Treatment should be based on a benefit-risk evaluation for the individual patient. There hasn’t been enough evidence to find consistent variables that can predict the incidence of AI-induced joint pain. However, some studies point to previous treatments as predictors for the increased likelihood of this symptom.
Anastrozole improves height outcomes in growing children with congenital adrenal hyperplasia
A review of the clinical trial safety database did not reveal evidence of clinically significant interaction in patients treated with Arimidex who also received other commonly prescribed medicinal products.
