These two interact in 4 distinct ways. Each one is explained separately below.
Why Are There 4 Interactions?
Evodia interacts with whole categories of medication. Drospirenone, Ethinyl Estradiol falls into 4 of those categories, so it can interact with Evodia in 4 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
1 of 4Why this applies to Drospirenone, Ethinyl Estradiol
Drospirenone, Ethinyl Estradiol falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Evodia interacts with.
Evodia extract and the evodia constituent rutaecarpine induce hepatic CYP1A2 enzyme activity. Evodia decreases levels of theophylline and caffeine, CYP1A2 substrates, by about 70% in animal models.
Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..
Here's the gist: Evodia appears to speed up a liver enzyme called CYP1A2, which can help break down certain medications faster. Your birth control pill (drospirenone with ethinyl estradiol) is partly processed by this pathway, so in theory Evodia could lower the amount of hormone circulating in your body. With less hormone around, the worry is reduced protection against pregnancy, and possibly some breakthrough spotting or irregular bleeding.
That said, the evidence here is weak. This comes from lab and animal studies (looking at caffeine and theophylline), not from people taking the pill. We can't say how big the effect would be in real life. Still, because an unplanned pregnancy is a serious outcome, I'd play it safe and check with your pharmacist or doctor before combining the two.

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS
2 of 4Drospirenone, Ethinyl Estradiol also falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS.
Animal research shows that concomitant administration of ketoconazole, a known CYP3A4 inhibitor, with the alkaloid constituents of evodia significantly increases the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents.
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 key thing to know about this pairing: your birth control pill, Yasmin (drospirenone with ethinyl estradiol), acts as a mild blocker of a liver enzyme called CYP3A4. Evodia happens to be broken down by that same enzyme. So in theory, your pill could slow the breakdown of evodia and let its compounds build up a bit higher than expected. The concern points toward evodia levels rising, not changes to your contraceptive itself.
I want to be honest about the strength of this: it comes only from lab and animal studies, not from people, so it's more of a theoretical caution than a proven problem. Still, since evodia isn't well studied in humans, I'd run it by your pharmacist or doctor before combining the two.

CYTOCHROME P450 1A2 (CYP1A2) INHIBITORS
3 of 4Drospirenone, Ethinyl Estradiol also falls under CYTOCHROME P450 1A2 (CYP1A2) INHIBITORS.
The evodia constituent rutaecarpine is metabolized by CYP1A2.
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 thing to keep straight with this one: the concern runs from your birth control pill toward Evodia, not the other way around. Your combination pill (drospirenone with ethinyl estradiol) can gently slow down a liver enzyme called CYP1A2. One of Evodia's active compounds, rutaecarpine, is broken down by that same enzyme. So in theory, your pill could let Evodia build up a bit more than expected, which might make any of Evodia's effects feel stronger.
Honestly, this is based only on lab and animal research, so it's more of a maybe than a sure thing. Your pill's job of preventing pregnancy isn't being weakened here. Still, since Evodia isn't well studied in people, it's worth running it by your pharmacist or doctor before combining the two.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
4 of 4Drospirenone, Ethinyl Estradiol also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.
In vitro research shows that evodia extract inhibits hepatic CYP3A4. 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.
Your birth control pill (Yasmin, Gianvi, or Angeliq) contains drospirenone and ethinyl estradiol, two hormones that your liver clears using an enzyme called CYP3A4. Lab studies suggest Evodia might slow that enzyme down a bit. If that happened in your body, the hormones could build up slightly, which in theory could mean more of the usual side effects like nausea, breast tenderness, headaches, or mood changes. Drospirenone can also nudge up potassium, so that's worth keeping in mind too.
The important thing here: this is only seen in test tubes, never proven in people, so I wouldn't lose sleep over it. Still, before pairing Evodia with your pill, it's smart to run it by your pharmacist or doctor first.
