Kinetin and Aspirin, Dipyridamole

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Aspirin, Dipyridamole

Aspirin, Dipyridamole falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Kinetin interacts with.

In vitro research suggests that kinetin inhibits human platelet aggregation and activation. Also, evidence from animal research suggests that kinetin prolongs bleeding time. Theoretically, kinetin might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
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

Aggrenox combines aspirin and dipyridamole, two medicines that both work to keep your platelets from clumping together. That is exactly the point, since it helps prevent strokes, but it also means you already bruise and bleed a little more easily than usual.

Here is the wrinkle with kinetin: in lab and animal studies, it appears to make platelets less sticky and stretch out bleeding time on its own. Stacked on top of Aggrenox, the worry is simply more bleeding, things like easy bruising, nosebleeds, bleeding gums, or, rarely, something more serious. I'll be honest, this is only test-tube and animal evidence, so it's theoretical, not proven in people. Kinetin in a face cream almost certainly won't matter. Still, before swallowing any oral kinetin product, please run it by your pharmacist or doctor first.

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

“Aspirin with dipyridamole (Aggrenox) keeps platelets from clumping to prevent a second stroke, so it should be no surprise that the great bulk of this page is about bleeding. Most listed supplements can thin the blood further, and the risk reaches into ordinary life: beer and wine both carry major ratings because alcohol alongside aspi…”

About Kinetin

What is Kinetin?

  • Anti-aging skincare
  • Skin smoothing and texture
  • Reducing skin dryness and roughness
  • Evening skin tone
  • Cosmetic moisturizing

Kinetin is a plant growth hormone (a cytokinin) used mainly in topical anti-aging and skincare products, not as an oral dietary supplement. Early laboratory research and small studies suggest it may help skin texture and hydration, but high-quality human evidence is limited. If you want to try it, use it as a cosmetic skin product and check with a pharmacist or dermatologist, especially if you have sensitive skin.
