Estrogen raises the risk of cancer of the uterus lining. Estrogen, with or without a progestin, should not be used to prevent heart disease or dementia. In the Women's Health Initiative, estrogen alone raised the risk of stroke and blood clots in the legs, and estrogen with a progestin raised the risk of heart attack, stroke, invasive breast cancer, and blood clots in the lungs and legs. The vaginal cream carries the same boxed warning as estrogen tablets, and some estrogen can be absorbed into the blood.
Tell your care team straight away if you get any unusual vaginal bleeding, chest pain or shortness of breath, pain or swelling in a leg, sudden vision loss or change, a sudden severe headache or weakness on one side, yellowing of your skin or eyes, or swelling of your face, lips or throat.
