Provera vs. Estradiol
See how Provera and Estradiol compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Provera is a progestin used to treat abnormal bleeding and protect the uterine lining in women taking estrogen, while Estradiol is the estrogen that treats hot flashes, vaginal dryness, and bone loss.
Both carry boxed warnings for cardiovascular events, breast cancer, and dementia risk, and both are often prescribed together rather than as alternatives to each other.
Provera is typically taken for short set periods of days, while Estradiol is usually taken continuously once daily.
Provera vs. Estradiol Drug Summary

Provera vs. Estradiol Indications
Provera
Provera is FDA-approved to treat secondary amenorrhea and abnormal uterine bleeding caused by hormonal imbalance. It is also used to prevent endometrial hyperplasia in postmenopausal women who have a uterus and are taking daily conjugated estrogens.
Secondary amenorrhea
Abnormal uterine bleeding due to hormonal imbalance
Endometrial hyperplasia prevention in women on estrogen therapy
Estradiol
Estradiol is FDA-approved to treat moderate to severe hot flashes and vaginal atrophy of menopause. It also treats hypoestrogenism from ovarian failure or castration, prevents postmenopausal osteoporosis, and offers palliative treatment for certain breast and prostate cancers.
Moderate to severe vasomotor symptoms of menopause
Vulvar and vaginal atrophy of menopause
Hypoestrogenism due to hypogonadism or ovarian failure
Provera vs. Estradiol Pros and Cons
Provera
Provera addresses the progestin side of hormone therapy, protecting the uterus rather than treating menopause symptoms directly. Its short, defined dosing courses differ from the continuous daily use typical of estrogen therapy.
Pros
Short, defined treatment courses of 5 to 10 days for many uses
Effective at controlling abnormal uterine bleeding directly
Available in three tablet strengths for flexible dosing
Lower typical monthly list price, around $15 to $75
Cons
Does not treat hot flashes, vaginal dryness, or bone loss
Can cause mood changes such as depression or insomnia
Only approved as an oral tablet, unlike some hormone options
Estradiol
Estradiol directly relieves menopause symptoms and protects bone density, but unopposed use raises endometrial cancer risk in women with a uterus. It is available in more delivery forms than most other estrogens, giving patients more options if oral dosing does not suit them.
Pros
Directly relieves hot flashes and vaginal dryness
Also helps prevent postmenopausal osteoporosis
Available in patch, gel, vaginal, and injectable forms beyond tablets
Approved for use in certain breast and prostate cancer treatment
Cons
Requires added progestin protection for women with a uterus
Higher-frequency respiratory-related side effects reported in trials
Usually taken continuously every day rather than for a set course
