Mesoglycan and Nintedanib Esylate

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Nintedanib Esylate

Nintedanib Esylate 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 explains PharmD, Clinical Pharmacist

Here's the thing to know about combining mesoglycan with Ofev (nintedanib). Nintedanib already carries its own bleeding risk on its own, so the concern is that adding a supplement with mild blood-thinning properties could nudge that risk up a bit. In real life, that might show up as easy bruising, nosebleeds, bleeding gums, or, less commonly, more serious bleeding.

The good news: this is mostly a theoretical concern. The human studies we have suggest mesoglycan supports clot breakdown without really changing how your blood clots. So the worry is modest, not alarming. Still, because nintedanib itself can affect bleeding, I'd check with your doctor or pharmacist before adding mesoglycan, and let them know right away if you notice unusual bruising or bleeding.

From our pharmacist’s overview on the Nintedanib Esylate page

“You take Ofev (nintedanib) to slow lung scarring, and this page deserves a careful read before any supplement joins it. Of the 285 ingredients here, the biggest cluster, over 200, can add to bleeding risk, a real concern since nintedanib itself can make you bleed more easily.”

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.

About Nintedanib

What Is Nintedanib Used For?

Brand name: Ofev

Nintedanib capsules are approved for adults with idiopathic pulmonary fibrosis (IPF) — a chronic, progressive scarring of the lungs — and for adults with chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype, meaning fibrosing lung diseases that continue to worsen over time despite treatment.

Nintedanib capsules (including Ofev) are also indicated to slow the rate of decline in lung function in adults with systemic sclerosis-associated interstitial lung disease (SSc-ILD), a lung complication of the autoimmune condition systemic sclerosis (scleroderma). Note that the Nintedanib esylate capsule product is approved for IPF and chronic fibrosing ILDs with a progressive phenotype, but SSc-ILD approval is carried by Ofev and other nintedanib capsule products — always confirm with your prescriber which product you have been prescribed.
