Sage and Medroxyprogesterone Acetate, Oestrogens, Conjugated

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. Medroxyprogesterone Acetate, Oestrogens, Conjugated 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).

Moderate

P-GLYCOPROTEIN SUBSTRATES

1 of 3

Why this applies to Medroxyprogesterone Acetate, Oestrogens, Conjugated

Medroxyprogesterone Acetate, Oestrogens, Conjugated falls under P-GLYCOPROTEIN SUBSTRATES — the group Sage interacts with.

Theoretically, sage might increase levels of drugs transported by P-glycoprotein.
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.
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

If you take Premique (conjugated estrogens plus medroxyprogesterone) for menopause symptoms, here's the gist. Sage may block a little transporter pump called P-glycoprotein that helps move certain drugs around your body. In a lab dish, sage slowed that pump down. In theory, that could let a bit more of your hormone medication stay in your system, which might mean slightly stronger effects or side effects like breast tenderness, bloating, nausea, headaches, or spotting.

Now the honest part: this has only been seen in test tubes, not in real people, so it may not happen at all. Everyday cooking amounts of sage are very unlikely to matter. Concentrated sage extracts or the essential oil are the bigger question mark. Before adding a sage supplement, just run it by your pharmacist or doctor.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Medroxyprogesterone Acetate, Oestrogens, Conjugated also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP3A4. So far, this interaction has not been reported in humans.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Premique combines conjugated estrogens with medroxyprogesterone, and your body relies partly on a liver enzyme called CYP3A4 to clear these hormones. In lab dishes, sage extract has been shown to slow that enzyme down a bit. The thinking is that if CYP3A4 works slower, these hormones could linger longer and build up, which might nudge up estrogen-type side effects like breast tenderness, bloating, nausea, headaches, or spotting.

Here's the honest part: this has only been seen in test tubes, never confirmed in real people, so I wouldn't lose sleep over it. A little sage in your cooking is no concern at all. Concentrated sage capsules or essential oil are where I'd be more thoughtful. If you plan to use those regularly, just run it by your pharmacist or doctor first.

Moderate

ESTROGENS

3 of 3

Medroxyprogesterone Acetate, Oestrogens, Conjugated also falls under ESTROGENS.

Theoretically, sage might interfere with hormone therapy.
In vitro evidence suggests that geraniol, a constituent of Spanish sage (Salvia lavandulaefolia), exerts estrogenic activity. The clinical significance of this effect is unclear.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Premique combines conjugated estrogens with a progestin (medroxyprogesterone) and is often used for menopause symptoms like hot flashes. The concern here is mostly on paper. In lab dishes, a compound found in Spanish sage called geraniol showed mild estrogen-like activity. In theory, that could add a little to the estrogen signal your hormone therapy already provides.

Honestly, this is weak evidence from test-tube studies only, and we don't know if it actually means anything in real people. Everyday cooking with sage is very unlikely to matter. Concentrated sage extracts or essential oil are a different story and worth mentioning to your doctor. If you want to use sage regularly while on Premique, just run it by your pharmacist or prescriber first.

About Sage

What is Sage?

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.
