Interaction report

Peony and drospirenone, ethinyl estradiol, levomefolate

These two interact in 4 distinct ways. Each one is explained separately below.

Why Are There 4 Interactions?

Peony interacts with whole categories of medication. drospirenone, ethinyl estradiol, levomefolate falls into 4 of those categories, so it can interact with Peony in 4 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 4

Why this applies to drospirenone, ethinyl estradiol, levomefolate

drospirenone, ethinyl estradiol, levomefolate falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Peony interacts with.

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. 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

Beyaz is a birth control pill that combines drospirenone, a form of estrogen, and a folate. Part of how your body clears the estrogen component runs through a liver enzyme called CYP1A2. The idea here is that peony root might mildly slow that enzyme down, which could let estrogen levels drift a little higher than usual. In theory, that might mean more of the typical estrogen-related effects, like nausea, breast tenderness, bloating, or headaches.

I want to be honest about how shaky this is. It comes only from lab and test-tube studies (not from real people), and the effect on CYP1A2 looked weak. So I wouldn't lose sleep over it, but if you'd like to use peony, please run it by your pharmacist or doctor first.

Moderate

ESTROGENS

2 of 4

drospirenone, ethinyl estradiol, levomefolate also falls under ESTROGENS.

Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Beyaz is a combination birth control pill that contains estrogen (ethinyl estradiol) along with drospirenone and a folate. Here's the idea behind this interaction: peony root has shown estrogen-like activity in lab and animal studies, so in theory it could either add to your pill's estrogen effects or compete at the same receptors. That might tip you toward more estrogen-related complaints like breast tenderness, nausea, headaches, bloating, or mood changes.

I want to be honest that this is theoretical and based on lab and animal work, not real patient cases, and small culinary amounts are unlikely to matter. Larger, concentrated peony supplements are the bigger question mark. Before adding it, please check with your pharmacist or doctor so we keep your birth control working as intended.

CONTRACEPTIVE DRUGS

3 of 4

drospirenone, ethinyl estradiol, levomefolate also falls under CONTRACEPTIVE DRUGS.

Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.
Severity Moderate Likelihood Possible Evidence D

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Beyaz is a birth control pill that combines two hormones (drospirenone and ethinyl estradiol) plus a folate. Here's the thing about peony: in lab dishes and animal studies, compounds in peony root seem to act a little like estrogen and may bump up against your body's estrogen receptors. The concern is mostly theoretical, but two things could happen. Peony might slightly nudge up estrogen-related side effects like breast tenderness, nausea, bloating, or mood changes. There's also a thought it could compete with your pill's hormones.

I want to be honest: this is based on lab and animal work, not solid human studies, so I wouldn't panic. Still, since reliable birth control matters, please run peony past your pharmacist or doctor before adding it.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

4 of 4

drospirenone, ethinyl estradiol, levomefolate also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: Beyaz (a birth control pill that combines drospirenone, ethinyl estradiol, and a folate) is partly broken down by a liver enzyme called CYP3A4. Lab and animal studies suggest peony root may gently slow that enzyme down. If that happened in people, your body might clear the hormones a little more slowly, leaving slightly higher levels around. In theory that could mean a bit more of the usual side effects, like nausea, breast tenderness, headaches, or bloating.

I want to be honest, though: this is only seen in test-tube and animal work, never confirmed in humans, so it's a weak theoretical concern. Drospirenone can also nudge potassium up, so that's worth keeping in mind. Before adding peony, just check with your pharmacist or doctor.
