Indian Snakeroot and Piroxicam

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Piroxicam

Piroxicam falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Indian Snakeroot interacts with.

Theoretically, taking Indian snakeroot might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Indian snakeroot contains small amounts of the drug yohimbine. In vitro research shows that yohimbine inhibits platelet aggregation.
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 thing to keep in mind with this pairing. Piroxicam is an NSAID, and like other NSAIDs it can already make your blood a little slower to clot, which is why stomach upset, ulcers, and bleeding are known risks. Lab research suggests that one compound found in Indian snakeroot may also nudge platelets toward being less sticky. Stack the two together and you could, in theory, raise the odds of bruising or bleeding more easily.

I want to be honest about the strength of this, though. It's based only on test-tube and animal data, not on real people, so it's a theoretical concern rather than a proven one. Still, since Indian snakeroot is a potent plant on its own, please run this combination by your pharmacist or doctor before mixing them.

From our pharmacist’s overview on the Piroxicam page

“Piroxicam (Feldene) is a potent, long-acting NSAID for arthritis pain, and since it already carries real stomach-bleeding risk on its own, my honest read is that this page calls for genuine caution rather than a quick skim. Most of the 285 interacting supplements share a single problem: they thin the blood or blunt platelets, stacking…”

About Indian Snakeroot

What is Indian Snakeroot?

Indian Snakeroot
  • High blood pressure
  • Anxiety and stress
  • Insomnia
  • Agitation
  • Fever (traditional use)

Indian snakeroot is a traditional Ayurvedic plant that contains reserpine, a compound with real blood-pressure-lowering and sedative effects. Because its potent alkaloids can cause serious side effects like depression and very low blood pressure, it should never be used without medical supervision. It is not a safe or simple home remedy, and many countries restrict its use.
