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 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
