Rose Hip and Vorapaxar

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Vorapaxar

Vorapaxar falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Rose Hip interacts with.

Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation. This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.
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

Vorapaxar (Zontivity) is a blood thinner that keeps your platelets from clumping together, which lowers your risk of another heart attack or stroke. Here's the theoretical concern: rose hip contains a compound called rugosin E that, in lab dishes and animal studies, actually encouraged platelets to clump. If that happened in people, it could work against vorapaxar and make it a little less effective at preventing clots.

I want to be honest about the evidence, though. This has only been seen in test tubes and animals, never in humans, so it's far from proven. Eating rose hip jam or tea is unlikely to cause trouble; concentrated supplements are the bigger question mark. Since vorapaxar is protecting you from serious clots, please run any rose hip supplement past your pharmacist or doctor first.

From our pharmacist’s overview on the Vorapaxar page

“Vorapaxar (Zontivity) keeps platelets from clumping after a heart attack or clogged leg arteries, so it raises bleeding risk by design, and adding supplements calls for real caution. Of the 282 ingredients on file, 202 can thin the blood further, stacking their antiplatelet effects on the drug's.”

About Rose Hip

What is Rose Hip?

Rose Hip
  • Joint pain and osteoarthritis
  • Colds and flu
  • Source of vitamin C
  • Digestive complaints
  • Anti-inflammatory support

Rose hip is the vitamin C–rich fruit of the wild rose, used traditionally for colds and joint pain. A standardized rose hip powder has some research support for easing osteoarthritis symptoms, but evidence for most other uses is limited. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using it as a supplement.
