What are the potential side effects of conjugated estrogens for injection?

Conjugated estrogens for injection can raise a woman’s risk of breast, uterine and ovarian cancers. Other side effects include increased risk of stroke, heart attack, blood clots, dementia, gallbladder disease, high blood pressure, liver problems and high blood sugar.

Women using conjugated estrogens for injection may also experience headache, breast pain, vaginal bleeding or spotting, stomach cramps, bloating, fluid retention, nausea and vomiting, hair loss, and vaginal yeast infection.
