Conjugated Linoleic Acid (cla) 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 Conjugated Linoleic Acid (cla) interacts with.

Theoretically, CLA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Some clinical evidence suggests that intake of CLA reduces platelet aggregation by approximately 10%. The clinical significance of this effect is unclear.
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 thing to know about pairing CLA with ketoprofen. Ketoprofen is an NSAID, and like other drugs in that family, it already has its own mild blood-thinning effect because it interferes with how your platelets stick together. CLA may do something similar. One small line of research suggests CLA can lower platelet clumping by roughly 10 percent, so stacking it on top of ketoprofen could, in theory, nudge your bleeding risk a little higher.

I want to be honest, though: this concern is theoretical and based mostly on how these substances behave, not on strong human studies. For most people it likely won't cause a problem. Still, watch for things like easy bruising, nosebleeds, stomach upset, or dark stools, and check with your pharmacist or doctor before combining them.

About Conjugated Linoleic Acid (cla)

What is Conjugated Linoleic Acid (cla)?

Conjugated Linoleic Acid (cla)
  • Weight loss
  • Improving body composition
  • Sports and muscle support
  • Reducing inflammation
  • General wellness

CLA is a fatty acid found naturally in meat and dairy, and supplements are usually made from safflower oil. While it is popular for fat loss and body composition, research results are mixed and any real-world effect appears small at best. It is likely safe for short-term use in most healthy adults, but talk to your pharmacist or doctor before starting it.

About Ketoprofen

What Is Ketoprofen Used For?

Ketoprofen capsules (including the Orudis brand) are approved for rheumatoid arthritis, osteoarthritis, general pain management, and primary dysmenorrhea (painful menstrual periods). Ketoprofen extended-release capsules are approved for rheumatoid arthritis and osteoarthritis only — they are not recommended for acute pain because of their slow-release design.

Regardless of formulation, the goal is always to use the lowest effective dose for the shortest time needed.
