Sage and Norelgestromin, Ethinyl Estradiol

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. Norelgestromin, Ethinyl Estradiol 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 Norelgestromin, Ethinyl Estradiol

Norelgestromin, Ethinyl Estradiol 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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

The patch you're using (Ortho Evra) delivers two hormones, norelgestromin and ethinyl estradiol, that work as birth control. The concern on file is that sage might block a transporter protein called P-glycoprotein, which can move drugs around your body. In theory, slowing that transporter could let a bit more hormone hang around, which might mean more of the usual estrogen-type effects like nausea, breast tenderness, headache, or bloating.

Here's the honest part: this is only seen in lab dish studies, never reported in actual people. Sage used as a kitchen herb or an occasional tea is very unlikely to do anything. Concentrated extracts or sage oil are a different story, so if you use those regularly, just mention it to your pharmacist or doctor.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Norelgestromin, Ethinyl Estradiol 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

Your patch (Ortho Evra) delivers two active hormones, ethinyl estradiol and norelgestromin, and your liver clears the estrogen part using an enzyme called CYP3A4. In a test tube, water-based sage extracts slowed that enzyme down a bit. In theory, that could let estrogen levels drift a little higher, which might mean more of the usual estrogen-type effects like nausea, breast tenderness, headaches, or bloating.

Here's the honest part: this has only been seen in lab studies, never in real people, so it's quite weak evidence. Cooking with sage almost certainly won't matter. Concentrated sage extracts or the essential oil are the bigger question marks. If you plan to take sage regularly, just run it by your pharmacist or doctor first.

ESTROGENS

3 of 3

Norelgestromin, Ethinyl Estradiol 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

The Ortho Evra patch delivers two hormones, norelgestromin and ethinyl estradiol, to prevent pregnancy. The concern with sage here is pretty soft. In lab dish studies, a compound in Spanish sage called geraniol showed mild estrogen-like activity. In theory that could add to the estrogen signal your patch is already providing, but we honestly don't know if this happens in real people.

Here's the practical part. Sprinkling sage on your food is not going to throw off your birth control. This worry only comes from test tubes, not from patients, so I'd call it very weak. If you're using concentrated sage extracts or the essential oil regularly, just mention it to your pharmacist or doctor so they can keep an eye on things.

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.
