Pomegranate and Diclofenac

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

Minor

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Diclofenac

Diclofenac falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Pomegranate interacts with.

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.
Severity Minor Likelihood Unlikely Evidence B

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: your body clears diclofenac using a liver enzyme called CYP2C9, and the idea on file is that pomegranate might slow that enzyme down. If that happened, diclofenac could build up a little, which in theory could mean more of its usual side effects like stomach upset, heartburn, fluid retention, or a bump in blood pressure.

But honestly, I wouldn't lose sleep over this one. The concern comes mostly from lab and animal studies showing pomegranate blocks the gut form of this enzyme, not the liver form. In actual human studies, pomegranate juice and extract did not meaningfully change CYP2C9 activity. Enjoying pomegranate as food or juice is fine for most folks. If you're taking concentrated extracts regularly, just mention it to your pharmacist.

From our pharmacist’s overview on the Diclofenac page

“Diclofenac (Zorvolex) is an NSAID pain reliever that already stresses the stomach lining and kidneys on its own, so treat this list as a real safety issue, not fine print. Two thirds of the 306 supplements on file can thin the blood or slow clotting, and stacked on an NSAID that raises the odds of stomach bleeding.”

About Pomegranate

What is Pomegranate?

Pomegranate
  • Heart and blood vessel health
  • Antioxidant support
  • High blood pressure
  • Inflammation
  • Digestive upset
  • Skin health

Pomegranate is a nutrient-rich fruit that is high in antioxidants and is widely enjoyed as food and juice. Early research suggests it may support heart health and blood pressure, but the evidence is still limited and not strong enough to call it a proven treatment. As a food it is generally safe, but talk to your pharmacist or doctor before using concentrated extracts, especially if you are pregnant, breastfeeding, or take medications.

About Diclofenac

What Is Diclofenac Used For?

Brand name: Zorvolex

Diclofenac sodium topical gel is used to treat actinic keratoses (AK) — rough, scaly skin patches that form after years of sun exposure. These patches are considered precancerous, meaning they can develop into skin cancer if left untreated.

This is a topical gel, meaning it is applied directly to the skin over the affected area rather than taken by mouth. It belongs to the NSAID (nonsteroidal anti-inflammatory drug) family.
