Pu-erh Tea and Ketoprofen

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ketoprofen

Ketoprofen falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Pu-erh Tea interacts with.

Theoretically, pu-erh tea may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Pu-erh tea contains caffeine. Caffeine is reported to have antiplatelet activity. Theoretically, the caffeine in pu-erh tea might increase the risk of bleeding when used concomitantly with antiplatelet drugs. However, this interaction 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: ketoprofen is an NSAID, and like its cousins (ibuprofen, naproxen), it can already make you more prone to bleeding and stomach irritation on its own. Pu-erh tea contains caffeine, and in lab studies caffeine has shown some mild blood-thinning (antiplatelet) activity. Stacking those two together could, in theory, nudge your bleeding risk a little higher.

I want to be honest about the evidence here, though. This concern comes only from test-tube and animal work and has not actually been reported in people. A few cups of pu-erh as a normal drink is unlikely to cause trouble. Just keep an eye out for things like easy bruising, unusual bleeding, or stomach upset, and check with your pharmacist or doctor if you notice any of that.

From our pharmacist’s overview on the Ketoprofen page

“Bleeding is what worries me most with ketoprofen (Orudis, Oruvail Gel). As an NSAID, it already irritates the stomach lining and slows clotting, and 202 of the 252 supplements and herbs on this page can push that bleeding risk further.”

About Ketoprofen

What Is Ketoprofen Used For?

Brand names: Orudis, Oruvail Gel, Powergel, Oruvail Injection

Ketoprofen capsules (including the brand Orudis) are used to manage the signs and symptoms of rheumatoid arthritis and osteoarthritis, to treat pain, and to treat primary dysmenorrhea (painful menstrual periods).

Ketoprofen extended-release capsules are approved for rheumatoid arthritis and osteoarthritis only. Because of the way they slowly release the drug, ketoprofen extended-release capsules are not recommended for treating acute (sudden) pain.
