Prometrium vs. Bijuve
See how Prometrium and Bijuve compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Prometrium is progesterone alone, meant to be paired with a separate estrogen product, while Bijuve combines estradiol and progesterone into one daily capsule.
Both carry boxed warnings for cardiovascular disease, dementia, and breast cancer risk, but Bijuve also warns about endometrial cancer risk with unopposed estrogen.
Prometrium is used mainly to protect the uterus during estrogen therapy or to treat amenorrhea, while Bijuve is FDA-approved specifically for menopausal hot flashes.
Prometrium vs. Bijuve Drug Summary
Prometrium
Prometrium is a bioidentical progesterone capsule taken by mouth, usually at bedtime. It's FDA-approved to protect the uterine lining in women taking estrogen and to treat secondary amenorrhea, and it's often prescribed off-label for fertility support and PMDD.
Bijuve
Bijuve is a combination capsule containing bioidentical estradiol and progesterone, taken once daily by mouth. It's FDA-approved to treat moderate to severe hot flashes from menopause in women who still have a uterus, pairing hormone relief with endometrial protection in one pill.

Prometrium vs. Bijuve Indications
Prometrium
Prometrium is FDA-approved to prevent endometrial hyperplasia in postmenopausal women taking estrogen, and to treat secondary amenorrhea caused by low progesterone. Many clinicians also prescribe it off-label for fertility support and other hormonal conditions.
Prevents endometrial hyperplasia when combined with estrogen
Treats secondary amenorrhea
Off-label: luteal phase support in IVF
Off-label: preterm birth prevention with prior early delivery
Bijuve
Bijuve is FDA-approved to treat moderate to severe hot flashes caused by menopause in women who still have a uterus. The progesterone component protects the uterine lining from the effects of the estradiol, reducing the risk of endometrial overgrowth.
Moderate to severe menopausal hot flashes
For women with a uterus (protects the endometrium)
Single capsule combines estradiol and progesterone
Not approved for women without a uterus
Prometrium vs. Bijuve Pros and Cons
Prometrium
Prometrium delivers progesterone alone, giving prescribers flexibility to pair it with any estrogen dose or route in a personalized HRT plan. Its bioidentical structure and long track record make it a familiar option, though it must be taken as a separate pill from estrogen and contains peanut oil.
Pros
Bioidentical progesterone matches the body's natural hormone
Can be paired with any estrogen product for a custom regimen
Also approved for secondary amenorrhea, not just menopause
Long history of off-label use for fertility support and PMDD
Cons
Contains peanut oil, contraindicated with peanut allergy
Requires a separate estrogen pill, adding to the regimen
Higher monthly cost, roughly $497 to $936 versus Bijuve's $257 to $351
Bijuve
Bijuve simplifies hormone therapy by combining bioidentical estradiol and progesterone into a single daily capsule. It's approved specifically for hot flash relief, but its fixed-dose combination doesn't allow the two hormones to be adjusted separately.
Pros
Combines estradiol and progesterone in one capsule
FDA-approved specifically for menopausal hot flash relief
Lower monthly cost, roughly $257 to $351 versus Prometrium's $497 to $936
No peanut oil, an option for peanut-allergic patients
Cons
Only approved for women with a uterus who have hot flashes
Fixed-dose combination limits adjusting estrogen and progesterone separately
Not used for fertility treatment or secondary amenorrhea
