Climara vs. Bijuva
See how Climara and Bijuva compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Climara is a once-weekly estrogen-only patch, while Bijuva is a daily oral capsule combining bioidentical estradiol and progesterone.
Because Climara delivers estrogen alone, women with a uterus typically need a separate progestogen added to protect the uterine lining.
Both carry boxed warnings for blood clots, stroke, heart attack, and dementia risk in women 65 and older, though transdermal and oral estrogens carry somewhat different clot risk profiles.
Climara vs. Bijuva Drug Summary
Climara
Climara is a steroidal estrogen delivered through a once-weekly transdermal patch. It treats moderate to severe hot flashes and vaginal dryness from menopause, hormone deficiency from ovarian failure or castration, and helps prevent postmenopausal osteoporosis. The patch is changed once a week and comes in six strengths so a clinician can adjust the dose over time.
Bijuva
Bijuva is an oral capsule combining bioidentical estradiol and bioidentical progesterone in one pill. It is approved specifically to treat moderate to severe hot flashes in menopausal women who still have a uterus, since the progesterone component protects the uterine lining. It is taken once daily with food, which is needed for the progesterone to absorb properly.

Climara vs. Bijuva Indications
Climara
Climara treats several menopause-related and hormone-deficiency conditions rather than hot flashes alone. It is also used off-label as part of feminizing hormone therapy. Its multiple patch strengths let clinicians tailor estrogen dosing to the specific condition being treated.
Moderate to severe menopausal hot flashes
Vaginal and vulvar atrophy from menopause
Hypoestrogenism from ovarian failure or castration
Prevention of postmenopausal osteoporosis
Bijuva
Bijuva has a single, narrower FDA approval: treating moderate to severe hot flashes in menopausal women who still have a uterus. It is not approved for osteoporosis prevention, vaginal atrophy, or use in women without a uterus. Its built-in progesterone makes it a self-contained option for women who need endometrial protection alongside estrogen.
Moderate to severe menopausal hot flashes
Only for women with an intact uterus
Not approved for osteoporosis prevention
Not approved for vaginal or vulvar atrophy
Climara vs. Bijuva Pros and Cons
Climara
Climara's transdermal delivery skips first-pass liver metabolism, which may lower clotting risk compared with oral estrogen, and its six patch strengths allow fine-tuned dosing. Because it delivers estrogen alone, most women with a uterus need to add a separate progestogen. It is also one of the most affordable estrogen therapies on the market.
Pros
Skips liver first-pass metabolism, potentially lowering VTE risk
Six patch strengths allow precise dose titration
Approved for osteoporosis prevention and vaginal atrophy, not just hot flashes
Roughly $19 to $59 per month, far less than Bijuva's cash price
Cons
Women with a uterus usually need a separate progestogen added
Patch can cause skin irritation or site reactions
Requires weekly site rotation and patch changes
Six different strengths can make initial dose selection more complex
Bijuva
Bijuva combines bioidentical estradiol and progesterone in one daily capsule, so women with a uterus get endometrial protection without a second prescription. Being an oral estrogen, it goes through liver metabolism, which may carry a different clot risk profile than a patch. It is also considerably more expensive and has no generic option.
Pros
Combines estrogen and progesterone in a single daily capsule
Uses bioidentical hormones matching the body's own estradiol and progesterone
No separate progestin prescription needed for uterine protection
Only two dose strengths simplify prescribing decisions
Cons
Oral dosing undergoes liver first-pass metabolism
Must be taken with food, and a high-fat meal changes absorption
No generic version currently available
Roughly $257 to $351 per month, much higher than Climara's list price
