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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Esomeprazole, Naproxen

Esomeprazole, Naproxen falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Thyme interacts with.

Theoretically, thyme leaf extract might have additive effects with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that thyme leaf extract has antiplatelet effects. However, this effect has not been observed 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 explains PharmD, Clinical Pharmacist

Vimovo combines naproxen (an anti-inflammatory pain reliever) with esomeprazole (a stomach-acid blocker added to protect your gut). The piece that matters here is the naproxen. Like other NSAIDs, naproxen already makes your platelets a little less sticky, which can raise the risk of bruising or bleeding, especially in the stomach.

The concern with thyme is purely theoretical. In test tube and animal studies, thyme leaf extract showed mild blood-thinning activity, but this has never actually been seen in people. The amount of thyme you cook with is not a worry at all. Even concentrated supplements are unlikely to cause trouble, but if you take thyme regularly and notice easy bruising, dark stools, or unusual bleeding, check in with your pharmacist or doctor.

From our pharmacist’s overview on the Esomeprazole, Naproxen page

“Bleeding risk is the thread running through nearly this whole page. Vimovo pairs naproxen, an anti-inflammatory that already makes stomach bleeding more likely, with esomeprazole on board to shield the gut, and most of the supplements flagged here could push that bleeding risk higher still.”

About Thyme

What is Thyme?

Thyme
  • Cough and respiratory congestion
  • Sore throat
  • Digestive upset
  • Antimicrobial and antiseptic uses
  • Flavoring in cooking

Thyme is a common kitchen herb that has long been used for coughs, sore throats, and digestive complaints. It is generally safe in the amounts found in food, and some cough products that combine thyme with other herbs have modest supporting evidence, but high-quality research on thyme alone is limited. The concentrated essential oil should never be swallowed undiluted.
