These two interact in 3 distinct ways. Each one is explained separately below.
Why Are There 3 Interactions?
Sage interacts with whole categories of medication. Bazedoxifene Acetate, Conjugated Estrogens falls into 3 of those categories, so it can interact with Sage in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
P-GLYCOPROTEIN SUBSTRATES
1 of 3Why this applies to Bazedoxifene Acetate, Conjugated Estrogens
Bazedoxifene Acetate, Conjugated Estrogens falls under P-GLYCOPROTEIN SUBSTRATES — the group Sage interacts with.
In vitro research suggests that common sage (Salvia officinalis) can inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.
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.
Here's the gist for Duavee (conjugated estrogens with bazedoxifene). Lab studies hint that sage might block a transporter called P-glycoprotein, which helps move certain drugs in and out of your body. If that happens, a bit more of the medication could stick around, which in theory might mean slightly stronger estrogen-related effects like breast tenderness, bloating, nausea, or spotting.
The important word here is theoretical. This was only seen in a test tube, never in real people, so I wouldn't lose sleep over it. Sage used in cooking is very unlikely to matter. Concentrated sage extracts or sage essential oil are a different story and deserve more caution. If you plan to take sage regularly, just give your pharmacist or doctor a heads-up first.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
2 of 3Bazedoxifene Acetate, Conjugated Estrogens also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP3A4. So far, this interaction has not been reported in humans.
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.
Here's the gist for Duavee (conjugated estrogens with bazedoxifene). Your body partly clears the estrogen portion using a liver enzyme called CYP3A4. In lab tests, water-based sage extracts seem to slow that enzyme down. If that happened in real life, the estrogen could build up a little, which might mean slightly stronger hormone effects like breast tenderness, bloating, nausea, or spotting.
I want to be honest about how shaky this is. This is only theoretical, based on test-tube studies, and it has never actually been reported in people. Everyday cooking amounts of sage are very unlikely to matter. The bigger question is concentrated sage supplements or sage oil. If you're using those regularly, just check in with your pharmacist or doctor first.

ESTROGENS
3 of 3Bazedoxifene Acetate, Conjugated Estrogens also falls under ESTROGENS.
In vitro evidence suggests that geraniol, a constituent of Spanish sage (Salvia lavandulaefolia), exerts estrogenic activity. The clinical significance of this effect is unclear.
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.
Here's the situation with sage and your Duavee (conjugated estrogens with bazedoxifene). This medication delivers estrogen to ease hot flashes and protect your bones. The concern on file is purely theoretical. In lab dish studies, a compound found in Spanish sage (geraniol) acted a little like estrogen. Nobody has shown this actually happens in real women taking the herb, so the practical risk looks small.
In theory, layering an estrogen-like effect on top of your hormone therapy could nudge estrogen activity higher, which is what people watch for breast tenderness, bloating, or spotting. Cooking with sage almost certainly won't matter. Concentrated sage extracts or capsules are the bigger question mark, so check with your pharmacist or doctor before using those regularly.

About Sage
What is Sage?
- Sore throat and mouth irritation
- Digestive upset
- Excessive sweating
- Memory and thinking
- Menopause symptoms (hot flashes)
- General antioxidant support
Sage is a common kitchen herb that is generally safe in food amounts and is traditionally used for sore throats, digestion, sweating, and memory. Some early research is encouraging for sore throat and menopausal hot flashes, but most uses are not well proven. Concentrated extracts and the essential oil should be used carefully because high doses contain a compound called thujone, which can be harmful.
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.
