Devil's Claw and Dexlansoprazole

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Devil's Claw interacts with whole categories of medication. Dexlansoprazole falls into 3 of those categories, so it can interact with Devil's Claw in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

1 of 3

Why this applies to Dexlansoprazole

Dexlansoprazole falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES — the group Devil's Claw interacts with.

Theoretically, devil's claw might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that devil's claw might inhibit CYP2C19, 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

Here's the gist for Dexilant (dexlansoprazole). Your body clears this acid-reducer partly through a liver enzyme called CYP2C19. Lab studies hint that devil's claw might slow that same enzyme down. If that happened in people, your dexlansoprazole could clear a little slower and build up slightly, which in theory means a stronger acid-lowering effect or a bump in mild side effects like headache, diarrhea, or stomach upset.

I want to be honest though: this is only a test-tube finding. It has never actually been shown in humans, so I wouldn't lose sleep over it. Dexlansoprazole is also a pretty forgiving medication, not a narrow-margin drug. Still, if you plan to use both regularly, give your pharmacist or doctor a heads-up so they can keep an eye on how you're feeling.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 3

Dexlansoprazole also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: your body partly uses an enzyme called CYP3A4 to clear dexlansoprazole (Dexilant) out of your system. In lab dishes, devil's claw has shown it might slow that enzyme down. If that happened in people, slightly more dexlansoprazole could hang around, which might mean a bit more of its usual side effects like headache, diarrhea, gas, or stomach upset.

The important caveat: this is only test-tube and theoretical evidence, and it has never actually been reported in humans. Dexlansoprazole is generally a forgiving, well-tolerated medication, so I wouldn't lose sleep over it. Still, since supplement strengths vary a lot, it's worth a quick chat with your pharmacist or doctor before adding devil's claw.

Minor

PROTON PUMP INHIBITORS (PPIs)

3 of 3

Dexlansoprazole also falls under PROTON PUMP INHIBITORS (PPIs).

Theoretically, devil's claw might decrease the effectiveness of PPIs.
Devil's claw has been reported to increase stomach acid, which might interfere with the effects of PPIs.
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 Dexilant (dexlansoprazole) and devil's claw. Dexlansoprazole works by quieting the acid pumps in your stomach so you get less heartburn and your esophagus can heal. The concern on file is that devil's claw has been reported to nudge stomach acid production up. If that happens, it could work against what your medication is trying to do, so you might notice your heartburn or reflux creeping back.

I want to be honest about the evidence though: this is largely theoretical and based on scattered anecdotal reports, not solid studies. It's rated a minor interaction. So I wouldn't lose sleep over it, but if you start the supplement and your symptoms return, mention it to your pharmacist or doctor before changing anything.

About Dexlansoprazole

What Is Dexlansoprazole Used For?

Brand name: Dexilant Solutab

Dexlansoprazole delayed-release capsules — sold as Dexilant and available as a generic — are used in patients 12 years of age and older to heal erosive esophagitis (EE), which is damage to the esophagus caused by stomach acid. They are also used to keep that damage healed and relieve heartburn over time.

In addition, dexlansoprazole treats heartburn from non-erosive gastroesophageal reflux disease (GERD) — that is, acid reflux that causes symptoms without visible damage to the esophagus. Both Dexilant and generic dexlansoprazole delayed-release capsules share these same approved uses.
