Mesoglycan and Tivozanib Hydrochloride

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Tivozanib Hydrochloride

Tivozanib Hydrochloride falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Mesoglycan interacts with.

Theoretically, combined use might increase bleeding risk. However, human evidence suggests that mesoglycan has profibrinolytic activity without affecting coagulation. These agents include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Severity Moderate Likelihood Possible Evidence B

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 keep in mind with Fotivda (tivozanib): this cancer medicine already comes with a known bleeding risk of its own. It can raise blood pressure and, in some people, lead to bleeding problems like nosebleeds, bruising more easily, or blood in the urine or stool. Mesoglycan contains heparin-like compounds that may gently nudge your blood toward being less likely to clot, so stacking the two could, in theory, add to that bleeding tendency.

To be fair, the human evidence here is on the weaker side, and some studies suggest mesoglycan mainly helps break down clots rather than strongly thinning the blood. Still, since you're on a serious medication, I'd run this by your oncologist or pharmacist before adding mesoglycan rather than guessing.

About Mesoglycan

What is Mesoglycan?

  • Vein health and chronic venous insufficiency
  • Leg ulcers
  • Peripheral artery disease and leg pain
  • Reducing blood clot risk
  • Hemorrhoids

Mesoglycan is a blend of natural sugar-protein compounds (glycosaminoglycans, including heparan sulfate and dermatan sulfate) taken from animal tissue and used mainly for blood vessel and circulation problems. Some small studies suggest possible benefit for vein-related conditions, but the overall evidence is limited and not strong. Because it can affect blood clotting, talk to your doctor or pharmacist before using it.
