Your doctor can help you to control some of the side effects. It is unclear what triggers them. Wearing thin layers of clothing that can be easily removed when a flush occurs may help. Some women experience vaginal dryness or discharge. Ask your doctor or chemist to recommend a non-oestrogen cream or lubricant.
Some premenopausal women experience irregularity with their periods.
Some women find that once they stop taking Tamoxifen their menstrual cycle becomes regular again. Other less common side effects of Tamoxifen are eye problems and a slightly increased chance of developing cancer of the uterus. Regular gynaecological check ups are recommended. Action Ask your general practitioner or gynaecologist for help to manage side effects. Tamoxifen prevents oestrogen from entering cells and so reduces the chances of other breast cancers developing.
