How It Works
High levels of estrogen trigger the rapid growth of the uterine
lining (endometrium). This stops sudden, heavy bleeding from
the uterine surface.
Why It Is Used
High-dose
estrogen is used to reduce sudden, heavy uterine
bleeding. Usually, 24 hours of
intravenous (IV) or oral (pills or tablets) estrogen
therapy is followed with 7 to 10 days of oral estrogen plus
progestin.1
During
perimenopause, when the body makes less estrogen, some
women take estrogen along with progestin to regulate the menstrual cycle and
reduce
dysfunctional uterine bleeding. For more information,
see birth control pills, patch, or ring.
How Well It Works
Estrogen therapy effectively controls sudden, heavy uterine
bleeding that is not caused by disease, pregnancy complication, cancer, or
another serious medical condition (dysfunctional uterine bleeding).1
Recurrence Dysfunctional uterine bleeding may return when treatment
with estrogen and progestin is stopped.
Side Effects
Frequent side effects caused by estrogen can include:
- Headaches.
- Nausea.
- Vaginal
discharge.
- Fluid retention.
- Swollen
breasts.
- Weight gain.
- Spotting or darkening of the
skin, particularly on the face.
Rare side effects include:
See Drug Reference for a full list of side effects. (Drug Reference

What To Think About
Short-term estrogen therapy is followed by 7 to 10 days of
estrogen-plus-progestin treatment to stimulate healthy growth of the
endometrium. When treatment stops, withdrawal bleeding, much like menstrual
bleeding, can occur.
Estrogen therapy is generally not recommended if you have:
- Uncontrolled
high blood pressure.
- Liver
disease.
- History of blood clots in a vein (deep vein thrombosis) or
lung (pulmonary embolism).
- History of
stroke.
- History of breast or uterine
cancer.
If you have very heavy bleeding, the benefits of short-term
estrogen therapy may outweigh the possible risks.
