Chrysin and Bazedoxifene Acetate, Conjugated Estrogens

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Chrysin interacts with whole categories of medication. Bazedoxifene Acetate, Conjugated Estrogens falls into 2 of those categories, so it can interact with Chrysin in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ESTROGENS

1 of 2

Why this applies to Bazedoxifene Acetate, Conjugated Estrogens

Bazedoxifene Acetate, Conjugated Estrogens falls under ESTROGENS — the group Chrysin interacts with.

Theoretically, chrysin might decrease the effects of estrogen therapy.
In vitro research suggests that chrysin might have antiestrogenic activity.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thinking behind this pairing. Duavee combines conjugated estrogens with bazedoxifene to ease menopause hot flashes and protect your bones. Chrysin, in test-tube studies, can block aromatase (the enzyme that makes estrogen) and may act against estrogen at its receptors. On paper, that could nudge against what Duavee is trying to do, possibly letting hot flashes, night sweats, or flushing creep back, or weakening the bone-protecting benefit over time.

I want to be honest, though: this concern comes only from lab research, not real people. Chrysin is also poorly absorbed, so it may never reach meaningful levels in the body. I wouldn't lose sleep here, but since Duavee is a long-term therapy, it's worth a quick chat with your doctor or pharmacist before adding chrysin.

GLUCURONIDATED DRUGS

2 of 2

Bazedoxifene Acetate, Conjugated Estrogens also falls under GLUCURONIDATED DRUGS.

Theoretically, chrysin might increase the clearance of drugs that are UGT1A1 substrates, thereby reducing their effectiveness.
In vitro research suggests that chrysin might induce UDP-glucuronosyltransferase 1A1 (UGT1A1).
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Duavee (conjugated estrogens plus bazedoxifene) and chrysin. Your body partly clears these hormones through a process called glucuronidation, using an enzyme known as UGT1A1. Some lab work suggests chrysin might speed that enzyme up. If that happened in real life, your body could clear the medication a little faster, which in theory might make Duavee work less well, so you could notice hot flashes creeping back or less benefit for your bones over time.

That said, I'd keep this in perspective. This is only test-tube research, the concern is rated minor and unlikely, and chrysin is barely absorbed when taken by mouth. I wouldn't lose sleep over it, but since Duavee matters for your symptoms and bone health, just run any chrysin supplement past your pharmacist or doctor first.

About Chrysin

What is Chrysin?

  • Bodybuilding and testosterone support
  • Anxiety and stress
  • Anti-inflammatory
  • Antioxidant support
  • Prostate health

Chrysin is a plant flavonoid sold mainly as a bodybuilding supplement claimed to raise testosterone or block estrogen, but human studies have not shown these benefits, largely because the body absorbs very little of it. Evidence for its other proposed uses is mostly limited to laboratory and animal research, so its real-world value is unclear. Talk with your pharmacist or doctor before using it.

About Estrogen and Bazedoxifene

What Is Estrogen and Bazedoxifene Used For?

Brand name: Duavee

  • Estrogen and bazedoxifene tablets are used to treat hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). Estrogen and bazedoxifene tablets are also used to prevent osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause. Estrogen is in a class of medications called hormones and bazedoxifene is in a class of medications called estrogen agonist–antagonists. Estrogen works by replacing estrogen that is normally produced by the body. Bazedoxifene is used to block the action of estrogen on the lining of the uterus, decreasing the risk of overgrowth that may lead to cancer.
