Black Currant 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 Black Currant interacts with.

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet 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 gist: diclofenac epolamine (Flector, Licart) is an NSAID, and like other NSAIDs it can make your blood a little slower to clot and can be a touch rough on the stomach lining. Black currant seed oil contains GLA, which may have a mild blood-thinning (antiplatelet) effect of its own. Put the two together and, in theory, you could see a slightly higher chance of bruising or bleeding.

I want to be honest about the strength of this: it's based on how these compounds behave in the lab, not on real cases in people, so the actual risk is likely small. The patch form is mostly working in one spot, which lowers the concern further. Eating black currant as food shouldn't matter. Still, if you take a concentrated supplement, mention it to your pharmacist or doctor, especially if you notice easy bruising, dark stools, or bleeding that won't stop.

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.”

About Black Currant

What is Black Currant?

Black Currant
  • Dry eyes and eye strain
  • Joint pain and inflammation
  • Immune and general wellness support
  • Cardiovascular health
  • Skin conditions (such as dry skin or eczema)

Black currant is a nutritious berry that is rich in vitamin C and antioxidants, and its seed oil contains the omega-6 fatty acid GLA. While it is enjoyed safely as a food and is popular as a supplement, solid human evidence for most health claims is still limited. Talk with your pharmacist or doctor before using concentrated supplements, especially if you are pregnant, nursing, or have a medical condition.
