What is this medication?
“Alert: US Warning
There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestin to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer.
Estrogen-alone therapy should not be used for the prevention of cardiovascular disease. Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease.
The WHI estrogen-plus-progestin study demonstrated an increased risk of invasive breast cancer.
Estrogen-alone therapy should not be used for the prevention of dementia. Estrogen plus progestin therapy should not be used for the prevention of dementia.”
How does this medication work?

How should I take this medication?
Estrace: Insert 2g to 4g intravaginally for 2 weeks, followed by a maintenance dose of 1g inserted 2 to 3 times weekly.
Estring: Insert 2mg ring intravaginally and keep in place for 90 days.
Vagifem: Insert 1 tablet once daily for 2 weeks, followed by a maintenance dose of 1 tablet inserted 2 to 3 times weekly.
Estrace: 0.5mg to 2mg once daily.
Vaginal Cream: Insert the applicator intravaginally. Cleanse the applicator after each use with water and soap.
Vaginal Insert: Insert with vaginal insert approximately 2 inches into the vaginal canal.
Vaginal Tablet: insert the tablet using an applicator intravaginally. Once inserted, press plunger until fully depressed, then remove applicator and discard. If tablet comes out of applicator prior to insertion, do not replace; use a new tablet filled applicator instead (if the tablet has fallen out of applicator but still remains in the package, it can be reinserted in the applicator for use).
Vaginal Ring: Insert the ring intravaginally as deeply as possible. You should not experience any discomfort. If ring is expelled prior to 90 days, it may be rinsed in lukewarm water and reinserted. If vaginal infection, ulceration, erosion, or adherence to vaginal wall develops, remove ring and reinsert only after healing is complete.
