What are the side effects of HRT?
Side effects are possible when taking HRT. These effects may last a few months, though people may react differently to HRT.
The common side effects of HRT include:
- Breast tenderness
- Stomach pain
- Vaginal bleeding
- A small increase in the risk of blood clots and breast cancer
HRT may also increase the risk of other medical conditions:
Endometrial cancer - women who have not had a hysterectomy and are postmenopausal are at an increased risk of endometrial cancer if they take oestrogen-only HRT.
Ovarian cancer - women taking HRT are also at a slightly increased risk of ovarian cancer.
Blood clots – HRT tablets, but not patches or gels, have been linked to an increased risk of developing blood clots.
Breast cancer – studies have shown that oestrogen-only HRT causes little or no increased risk of breast cancer. However, combination HRT may increase the risk of breast cancer, but if you stop taking HRT then your risk will reduce again.
If you or someone you know is experiencing side effects, or there is an emergency, for example, breathing problems or chest pain you should seek medical attention immediately.
