Why have I been prescribed Aromasin?
Aromasin (Exemestane) is a drug used to treat breast cancer in postmenopausal women (women who have gone through the menopause/change of life). It is a type of hormone treatment and is known as an aromatase inhibitor. Aromasin may be prescribed if your breast cancer comes back or progresses while you are taking tamoxifen.
How does it work?
Aromasin is most useful for breast cancers that rely on oestrogen for their growth (oestrogen receptor positive tumours) as it reduces the amount of oestrogen in the body.
When and how do I take Aromasin?
Aromasin comes as a tablet that you take once a day, preferably after a meal. It is best to take it at the same time each day. If you miss a dose you don’t need to take a replacement dose as the drug will remain in your system from the previous day.
What’s the dose?
- 25mg once a day.
Could they interact with other tablets?
It is not advisable to take other drugs containing oestrogen, such as the contraceptive pill or HRT, while you are taking Aromasin. There do not seem to be any other drugs that interfere with Aromasin.
Herbal supplements should be used with caution and only after informing your doctor first.
What are the possible risks or side-effects?
