Side-by-side comparison of bazedoxifene/conjugated estrogens and carbamazepine. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
minor Known Drug Interaction
John's Wort (Hypericum perforatum) preparations, phenobarbital, carbamazepine, and rifampin, may reduce plasma concentrations of some estrogens, possibly resulting in a decrease in therapeutic effects and/or changes in the uterine bleeding profile. The metabolism of bazedoxifene may be increased by concomitant use of substances known to induce UGTs, such as rifampin, phenobarbital, carbamazepine, and phenytoin.

Duavee is a combination medicine containing estrogen and a drug that blocks estrogen in some parts of the body. It is used to treat menopause symptoms and prevent bone loss after menopause in women with a uterus.
Carbamazepine is a medicine used to control seizures and treat nerve pain. It works by reducing abnormal electrical activity in the brain and calming nerve signals.
Duavee is used to treat moderate to severe hot flashes caused by menopause. It can also help prevent bone loss (osteoporosis) after menopause. You should only use Duavee if you are at significant risk of osteoporosis and other non-estrogen medications should be carefully considered. Use Duavee for the shortest time that works for you, based on your goals and risks.
Carbamazepine is used to treat certain types of seizures, including partial seizures and generalized tonic-clonic seizures. It can also treat mixed seizure patterns. Carbamazepine also treats the pain from trigeminal neuralgia, a nerve disorder that causes intense facial pain. It is also sometimes used for glossopharyngeal neuralgia.
Duavee contains two medicines. Estrogen helps with menopause symptoms and bone loss. Bazedoxifene blocks estrogen's effects in the uterus, which lowers the risk of uterine cancer that can happen when taking estrogen alone.
Carbamazepine is an anticonvulsant. It works by reducing the spread of seizure activity in the brain. It also stabilizes nerve impulses to reduce pain.

Duavee has serious warnings. It can increase the risk of uterine cancer, stroke, blood clots, and dementia. Women taking Duavee should not take additional estrogens. Estrogen should not be used to prevent heart disease or dementia. Talk to your doctor about the risks and benefits of Duavee.
Carbamazepine can cause severe skin reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), which can be fatal. If you are of Asian descent, you may need a blood test before starting this medicine. Carbamazepine can also cause serious blood problems like aplastic anemia and agranulocytosis. Contact your doctor right away if you develop a fever, sore throat, rash, or unusual bleeding or bruising.
Do not take Duavee if you are pregnant. It can harm your unborn baby. Duavee is not for women who can get pregnant.
Carbamazepine may harm an unborn baby. Talk to your doctor if you are pregnant or plan to become pregnant. It is not known if carbamazepine passes into breast milk, so talk to your doctor about breastfeeding.

bazedoxifene/conjugated estrogens is classified in the SERM / Estrogen Combination drug class, while carbamazepine sits within the Anticonvulsant class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, bazedoxifene/conjugated estrogens has 0 submissions while carbamazepine has 15,573. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to carbamazepine causes your body to break down estrogens and bazedoxifene faster than usual. this can lower the amount of medicine in your blood and make it less effective.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances.
