Caprylic Acid and Diclofenac epolamine

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

Moderate

NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)

Why this applies to Diclofenac epolamine

Diclofenac epolamine falls under NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs) — the group Caprylic Acid interacts with.

Theoretically, caprylic acid might increase plasma concentrations of NSAIDs.
In vitro research suggests that caprylic acid might displace NSAIDs from binding sites on albumin. This effect has not been reported in humans.
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 for Flector (diclofenac epolamine). Like other NSAIDs, diclofenac travels through your blood mostly stuck to a protein called albumin. The idea on file is that caprylic acid, a fatty acid, might bump diclofenac off those protein parking spots. That could leave a little more free, active drug floating around, which in theory might nudge up the typical NSAID side effects: stomach upset, heartburn, fluid retention, or higher blood pressure.

The honest part: this is theoretical, seen only in lab dishes and never confirmed in people. With the patch especially, very little gets into your blood. Food amounts of coconut oil are unlikely to matter. If you're using concentrated caprylic acid supplements, just run it by your pharmacist or doctor first.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

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 Caprylic Acid

What is Caprylic Acid?

Caprylic Acid
  • Candida and yeast overgrowth
  • Gut health support
  • Antimicrobial
  • Digestive health
  • Part of ketogenic diets

Caprylic acid is a medium-chain fatty acid found in coconut oil and palm kernel oil that is popularly used for yeast overgrowth and gut health. While laboratory studies show it has antimicrobial activity, strong human evidence for most supplement claims is limited. It is generally considered safe in food amounts, but talk with your pharmacist or doctor before using concentrated supplements.
