People being treated for primary breast cancer will usually take anastrozole for 5 to 10 years. If you miss a dose, you don’t need to take an extra dose the next day.
Results were based on data from nearly 4,000 women, aged 40-70, in 18 different countries. Treatment involved taking 1mg tablets of anastrozole daily for 5 years or a placebo. The survival of litters born to rats given anastrozole at 0.02 mg/kg/day and above (from Day 17 of pregnancy to Day 22 post-partum) was compromised. These effects were related to the pharmacological effects of the compound on parturition. There were no adverse effects on behaviour or reproductive performance of the first generation offspring attributable to maternal treatment with anastrozole. In acute toxicity studies in rodents, the median lethal dose of anastrozole was greater than 100 mg/kg/day by the oral route and greater than 50 mg/kg/day by the intraperitoneal route.
Cancer Chat is our fully moderated forum where you can talk to others affected by cancer, share experiences, and get support. Speak to your healthcare team about painkillers to help with this.

Anastrozole is usually given after surgery to reduce the risk of breast cancer coming back or spreading. This can help if you are getting side effects such as joint pain. However, only take a break from your medicine if you have discussed it with your doctor first and they agree to it. Aromatase inhibitors reduce the amount of aromatase in your body and this in turn stops your body producing oestrogen. This helps prevent cancer cells growing, as they no longer have anything to feed on.
Dr Morris explains how Anastrozole blocks the enzyme aromatase to reduce oestrogen levels, including how its presence within the body can be a risk factor for mutations causing the disease. Evidence was based on the IBIS-II study, an international, randomised double-blind, placebo-controlled trial, which showed fewer women developed breast cancer in the anastrozole group compared to the placebo group. Anastrozole was already authorised for use in the treatment of breast cancer in post-menopausal women and has been used off-label for prevention. Anastrozole, a hormone blocker used for many years to treat breast cancer, has been licensed for preventative use. In animal studies adverse effects were only seen at high doses.
Studies in animals have shown reproductive toxicity (see section 5.3). Arimidex is contraindicated during pregnancy (see section 4.3). The enzymes mediating metabolism of anastrozole have not been identified. Cimetidine, a weak, unspecific inhibitor of CYP enzymes, did not affect the plasma concentrations of anastrozole.
It may also be possible to use a coil (IUD or intrauterine device). However, you would need to discuss this with your treatment team as not all types are suitable for women with breast cancer. Do not take other drugs containing oestrogen, such as hormone replacement therapy (HRT), while you’re taking anastrozole as this may interfere with its effectiveness. Anastrozole can also be used to treat breast cancer that has come back (recurrence). It can also be given to treat breast cancer that has spread to another part of the body (secondary breast cancer), when it’s often given alongside another drug.
During this time you’re likely to have menopause symptoms as your body gets used to having less oestrogen. These symptoms will gradually improve as your body adjusts to the medicine. Most people who take anastrozole will have had surgery, radiotherapy or sometimes chemotherapy to treat their breast cancer first.
Breastfeeding is not recommended while having anastrozole, or within a week of the last dose. This is because there’s a risk the drugs could be passed on through breast milk. Sometimes anastrozole is given alongside ovarian suppression to women who haven’t yet been through the menopause. If your cancer is hormone receptor negative, then anastrozole will not be of any benefit. Breast cancer treatment that works by reducing the amount of oestrogen in the body.
