Devil's Claw and Triamcinolone

Here is the interaction we found between these two, with the evidence behind it.

Minor

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Triamcinolone

Triamcinolone falls under P-GLYCOPROTEIN SUBSTRATES — the group Devil's Claw interacts with.

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 Devil's Claw and triamcinolone: triamcinolone is a corticosteroid that gets shuttled around partly by a cellular pump called P-glycoprotein. In lab dish studies, devil's claw seems to slow that pump down. In theory, that could let a little more triamcinolone linger inside your cells, which might slightly bump up steroid-type effects like fluid retention, mood or sleep changes, higher blood sugar, or stomach upset.

The honest takeaway? This is theoretical, based only on test-tube research, and it's rated a minor interaction. For most folks it likely won't cause noticeable trouble. Still, since steroid products vary and devil's claw strength differs, it's worth a quick chat with your pharmacist or doctor before combining them.
