Question from ELK: I'm using Estring for estrogen supplementation because of the dryness from Arimidex; is there any new information about the safety of doing this?
Answers - Kathy D. Miller, M.D. Nothing new. But our previous studies would raise concern that this might not be a safe approach. The Estring (estradiol vaginal ring) or other topical forms of estrogen like Premarin (chemical name: conjugated estrogens tablets, USP) cream have very little estrogen that is absorbed and circulates through the body, but they do have some estrogen that is absorbed. And since the aromatase inhibitors like Arimidex function by decreasing the estrogen level, that makes us concerned that the estrogen that is absorbed from the Estring could interfere with the results of Arimidex. Arimidex reduces estrogen levels, and you are giving some of that estrogen back with the Estring, so we would not recommend that combination.
