Devil's Claw and Vericiguat

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

Minor

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Vericiguat

Vericiguat 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 situation with Verquvo and devil's claw. Your body uses a kind of cellular pump called P-glycoprotein to move certain drugs out of cells, and lab studies suggest devil's claw may slow that pump down a bit. Since vericiguat is carried by this pump, the theory is that blocking it could let a little more of the drug stick around in your system.

I want to be honest about how thin this evidence is. This comes only from test-tube research, not from people, and we genuinely don't know if it matters in real life. If anything did shift, you might notice more of vericiguat's usual effects, like lightheadedness, dizziness, or lower blood pressure. I wouldn't lose sleep over this, but do mention the supplement to your pharmacist or doctor before adding it, since heart failure deserves a careful eye.

About Vericiguat

What Is Vericiguat Used For?

Brand name: Verquvo

Verquvo (vericiguat) is used to reduce the risk of cardiovascular death and hospitalization due to heart failure. It is specifically for adults with symptomatic chronic heart failure whose heart pumps with reduced function (ejection fraction less than 45%), following a recent hospitalization for heart failure or a need for IV diuretics given outside the hospital.

Verquvo is taken on top of other standard heart failure treatments — it is not a replacement for them.
