Devil's Claw and Drospirenone, Ethinyl Estradiol

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Devil's Claw interacts with whole categories of medication. Drospirenone, Ethinyl Estradiol falls into 2 of those categories, so it can interact with Devil's Claw in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Drospirenone, Ethinyl Estradiol

Drospirenone, Ethinyl Estradiol falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Devil's Claw interacts with.

Theoretically, devil's claw might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that devil's claw might inhibit CYP3A4, although this 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

Your birth control pill (Yasmin, Gianvi, Angeliq) contains drospirenone and ethinyl estradiol, and both of these hormones are broken down partly by a liver enzyme called CYP3A4. Lab studies hint that devil's claw might slow that enzyme down a little. If that happened in real life, your hormone levels could drift a bit higher than usual, which in theory might mean more of the typical pill side effects like breast tenderness, nausea, headaches, or fluid retention.

Here's the honest part: this is based only on test-tube research, and nothing like it has actually been seen in people. So it's more of a 'good to know' than something to worry about. Still, since this combo hasn't been well studied, run it by your pharmacist or doctor before adding devil's claw.

Minor

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Drospirenone, Ethinyl Estradiol also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, devil's claw might increase levels of P-glycoprotein substrates.
In vitro research shows that devil's claw inhibits P-glycoprotein, which transports many drugs out of cells. This might increase intracellular levels of P-glycoprotein substrates, although it is unclear if this effect would be clinically important.
Severity Minor 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

Here's the gist with your birth control pill (drospirenone with ethinyl estradiol) and devil's claw. In lab dishes, devil's claw seems to block a cellular pump called P-glycoprotein, which helps move certain drugs out of cells. The thinking is that blocking this pump might let a little more of the medication linger in the body. For your pill, that could in theory nudge up estrogen-related effects like nausea, breast tenderness, or fluid retention.

Honestly though, this is only a theoretical concern based on test-tube work, not on real people, and the interaction is rated minor. I wouldn't lose sleep over it. Since drospirenone can already raise potassium a bit, it's still worth a quick chat with your pharmacist or doctor before adding devil's claw.
