Oolong Tea and Aspirin, Carisoprodol

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Aspirin, Carisoprodol

Aspirin, Carisoprodol falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Oolong Tea interacts with.

Theoretically, oolong tea might increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Oolong tea contains caffeine. Caffeine is reported to have antiplatelet activity. Theoretically, the caffeine in oolong tea might increase the risk of bleeding when used concomitantly with these agents. 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

Soma Compound combines aspirin, which thins the blood by blocking platelets from clumping, with carisoprodol, a muscle relaxer. The concern here is really about the aspirin side. Oolong tea contains caffeine, and in lab studies caffeine showed some mild platelet-blocking activity of its own. So in theory, the two together could nudge your bleeding risk up a little, showing up as things like easier bruising, nosebleeds, or stomach upset.

Honestly, this is a theoretical concern built on test-tube data, and it has not actually been reported in people. A few cups of oolong tea are very unlikely to cause trouble. If you drink large amounts daily or take aspirin regularly, just mention it to your pharmacist so they can keep an eye on things.

From our pharmacist’s overview on the Aspirin, Carisoprodol page

“This is one of the longer interaction lists on the site, and for Soma Compound (aspirin plus the muscle relaxant carisoprodol) the caution is earned. Of the 266 supplements and herbs on file, just over 200 push in the same direction as aspirin itself, thinning the blood and raising the odds of bleeding.”

About Oolong Tea

What is Oolong Tea?

  • Weight management
  • Mental alertness and energy
  • Heart health
  • Blood sugar support
  • Antioxidant support

Oolong tea is a traditional partially oxidized tea made from the same plant as green and black tea, and it provides caffeine and plant antioxidants. As a beverage it is generally considered safe for most healthy adults in moderate amounts, but evidence for specific health benefits like weight loss or blood sugar control is limited. If you have heart, blood pressure, or caffeine-sensitivity concerns, talk with your pharmacist or doctor.
