Devil's Claw and Ensartinib

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. Ensartinib 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 Ensartinib

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

Here's the short version for Ensacove (ensartinib): your body relies on a liver enzyme called CYP3A4 to break this cancer medicine down. Devil's claw has shown, in test-tube studies only, that it may slow that same enzyme. If that happened in real life, ensartinib could build up a bit higher than expected, which might mean more of its usual side effects like nausea, rash, swelling, tiredness, or changes in liver blood tests.

I want to be honest about the strength of this, though. This concern comes from lab research, not from people taking the two together, so it's more theoretical than proven. Still, because ensartinib is a serious cancer drug, I'd loop in your oncologist or pharmacist before adding devil's claw rather than starting it on your own.

Minor

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Ensartinib 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 situation with these two. Ensartinib (Ensacove) is a targeted cancer therapy, and part of how your body moves it around is through a little pump called P-glycoprotein. In lab dish studies, devil's claw appears to slow that pump down. In theory, that could let a bit more ensartinib linger inside your cells, which might nudge its levels and side effects (things like rash, nausea, tiredness, or liver enzyme changes) slightly upward.

I want to be honest, though: this is only test-tube data, not something proven in real people, so it may not matter at all in practice. Still, ensartinib is a serious medication, so please don't add devil's claw without first checking with your oncology team or pharmacist.

From our pharmacist’s overview on the Ensartinib page

“Ensartinib (Ensacove) holds ALK-positive lung cancer in check, and I read this page as a genuine warning rather than fine print. Most of the entries can change how much of the drug actually reaches the bloodstream, because the body clears ensartinib through the CYP3A4 enzyme.”
