Cat's Claw and Ibuprofen, Hydrocodone

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

Why Are There 2 Interactions?

Cat's Claw interacts with whole categories of medication. Ibuprofen, Hydrocodone falls into 2 of those categories, so it can interact with Cat'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 Ibuprofen, Hydrocodone

Ibuprofen, Hydrocodone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Cat's Claw interacts with.

Theoretically, cat's claw might increase or decrease the levels and effects of drugs metabolized by CYP3A4.
Cat's claw may affect the clearance of drugs metabolized by CYP3A4. In vitro research shows that cat's claw can inhibit CYP3A4 enzymes. In one case report, a patient taking cat's claw (at an unspecified dose) experienced increased serum levels of atazanavir, ritonavir, and saquinavir, all of which are CYP3A4 substrates. Levels returned to normal 15 days after discontinuation of the cat's claw supplement, suggesting inhibition of CYP3A4 by cat's claw. In contrast, animal research suggests that rhynchophylline, an alkaloid contained in cat's claw, induces CYP3A expression and accelerates the metabolism of nirmatrelvir, the active component in the nirmatrelvir/ritonavir combination product.
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

This combination pill pairs ibuprofen (an anti-inflammatory) with hydrocodone (an opioid pain reliever). The hydrocodone part is actually a prodrug that your liver partly turns into its more active form, and it leans on CYP3A4 (along with CYP2D6) for part of that processing. Cat's claw has shown in lab tests that it might block CYP3A4, though animal data hints it could speed it up too, so the direction here is genuinely murky.

If cat's claw slows that enzyme, hydrocodone and its byproducts could linger longer, which may mean more drowsiness, dizziness, constipation, nausea, or slowed breathing. This is theoretical and based only on lab and animal studies, so I wouldn't panic. Still, please run it by your pharmacist or doctor before combining them.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Ibuprofen, Hydrocodone also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, cat's claw may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Cat's claw contains rhynchophylline and isorhynchophylline. Animal research suggests that these alkaloids can inhibit platelet aggregation. This interaction 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

This combination pill pairs ibuprofen (an NSAID pain reliever) with hydrocodone (an opioid). The piece that matters here is the ibuprofen. Like other NSAIDs, ibuprofen already makes your platelets a little less sticky and can irritate the stomach lining, so it carries some bleeding risk on its own.

Cat's claw contains plant compounds that, in lab and animal studies, also seemed to slow platelets from clumping together. Stacked on top of ibuprofen, the theory is that bruising or bleeding (think nosebleeds, stomach upset, or dark stools) could become a bit more likely. To be fair, this is only based on test-tube and animal data and has never been reported in real people, so it's a precaution rather than a proven problem. If you take both regularly or notice unusual bruising, check in with your pharmacist or doctor.
