Peony and Diclofenac epolamine

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Diclofenac epolamine

Diclofenac epolamine falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Peony interacts with.

Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.
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 situation with peony and diclofenac epolamine (the Flector or Licart patch). Diclofenac is an NSAID, and even though it's applied to the skin, some of it reaches your bloodstream. NSAIDs already make platelets a bit less sticky, so they can nudge up bleeding risk on their own.

Peony, in lab and animal studies only, seems to thin the blood a little too. So the worry is mainly additive: two things gently leaning the same way. Watch for easy bruising, nosebleeds, dark stools, or stomach upset. Keep in mind this is theoretical and based on weak evidence, not human studies, so don't panic. Still, check with your pharmacist or doctor before pairing them, especially if you take other blood thinners.

From our pharmacist’s overview on the Diclofenac epolamine page

“Even as a patch, diclofenac epolamine (Flector, Licart) is still an NSAID that reaches the bloodstream, and its 292 supplement interactions call for genuine care, six of them rated major. The bulk of the list, 202 ingredients, thins the blood or slows clotting, which stacks onto an NSAID's built-in bleeding risk.”
