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 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
