If someone is already on systemic hormone therapy (pills or patches), do they still need local vaginal estrogen?

If you are already on systemic hormone therapy (like pills or patches), you may still need local vaginal estrogen if you are experiencing vaginal symptoms such as dryness, itching, burning, painful sex, or frequent urinary tract infections. Systemic hormone therapy does not always fully resolve these local symptoms, because the amount of estrogen that reaches the vaginal tissues may not be enough for optimal vaginal health.

Here at Alloy, our menopause-trained doctors and experts emphasize that adding a local vaginal estrogen (like our Estradiol Vaginal Cream) is both safe and effective—even when you are already using systemic hormone therapy. Vaginal estrogen works directly on the tissues that need it most, without significantly increasing your overall estrogen levels or risk.

• Dr. Rachel Rubin, a leading urologist, and Dr. Corinne Menn, Alloy’s own medical advisor, both confirm that it is common and appropriate to use both systemic and local vaginal estrogen together for the best symptom relief. You are not “overdosing” on estrogen by doing this, because vaginal estrogen is minimally absorbed into the bloodstream.
