Risks and Warnings for Premarin (Conjugated Estrogens)Skip Risks and Warnings section. Skip to Tips section.
- Higher risk if:
- › Using estrogen for more than one year
Vaginal bleeding after menopause can be a warning sign of uterus (endometrial) cancer, so let your doctor know if you notice any unusual bleeding. When estrogen is prescribed to women after menopause who still have a uterus, progestin should be used with it to lower the risk of cancer. Low-dose vaginal estrogen products are often a better choice than oral pills for women 65 years or older who have vaginal symptoms.
This is a black box warning. The FDA requires this warning when there is a significant risk of serious or life-threatening effects that anyone taking the drug should consider.
