Tell your doctor right away if you have unusual vaginal bleeding while you use estradiol emulsion. Talk with your doctor if you have questions about the benefits and risks of using estradiol emulsion.

Estradiol emulsion should be used for the shortest possible time at the lowest effective dose to minimize the risk of these side effects. Talk with your doctor regularly about your need to use estradiol emulsion.
