What should I take note of while using/taking this medicine?
Let your doctor know if you are undergoing treatment for high cholesterol levels or high lipid (fat) levels.
For as long as you are taking Tamoxifen, you will need to have regular blood tests to check your body's response to the medicine. Your doctor will advise you about how often you need to have blood tests.
You should keep regular appointments with your gynaecologist, especially if you have not had a hysterectomy (removal of the womb). If you are taking Tamoxifen for more than one year, you may need to have your eyes checked by an eye specialist once a year. Ask your doctor if this is necessary.
When should I not use this medicine?
Alert your doctor if you have a history of blood clotting problems such as deep vein thrombosis (a blood clot in the leg veins) or pulmonary embolism (a blood clot in a lung artery), or if you are taking blood-thinning medicines such as warfarin.

What side effects could I experience?
Common side effects with Tamoxifen include hot flushes, fluid accumulation (which may cause your feet and ankles to swell), nausea, vomiting, loss of appetite, stomach discomfort, itching in the genital area and some loss of hair. At the beginning of treatment, you may also feel some pain in the bones and in the affected breast. These are usually not serious and can be managed with simple medicines and rest. For example, nausea, vomiting and the lack of appetite can be improved by taking smaller but more frequent meals throughout the day.
If you are still having menstrual periods, your menstrual cycle may change or your periods may stop while you are taking Tamoxifen. This is normal and is not a cause for worry. However, if you experience irregular or unusual vaginal bleeding, unusual vaginal discharge, pain or pressure in the lower abdomen or pelvis, see your doctor as soon as possible.
You may also experience some problems with your vision, such as blurring. Always inform your doctor of any changes in your vision. Avoid driving and operating machinery if you are not able to see clearly.
