Vagifem® is a local estrogen therapy.
Vagifem® (estradiol vaginal inserts) 10 mcg delivers treatment directly to the vagina. It’s a local estrogen treatment—not to be confused with systemic hormone replacement therapy.
Just what is estrogen?
Estrogen is a hormone responsible for changes in the vagina and uterus. There are several forms of estrogen, including estradiol, which is used in several LETs; another LET uses conjugated, or combined, estrogens.
What is local estrogen therapy?
“Local” means that the treatment is applied directly to the affected area—in this case, the vagina. Local delivery of estrogen:
Results in quantifiably lower doses of estrogen than systemic estrogen treatments
Limits the amount of estrogen a woman may be exposed to
Compare local estrogen therapy to other types of treatment used to treat vaginal symptoms that happen after menopause, and ask your health care provider to discuss local estrogen therapy with you.
