Nampons™ are clinically proven to stop nosebleeds fast

Nampons contain a proprietary and patented active micro-dispersed oxidized cellulose that stops anterior bleeding fast. Oxidized cellulose has been used for over 50 years by millions of hospitals and first responders to help stop mild to moderate bleeding.

Efficacy

In 2017, a comprehensive study of hemostatic nasal plugs impregnated with oxidized cellulose was conducted over a two-year period and published in the Netherlands by Dr. teGrotenhuis. Titled "Use of Hemostatic Nasal Plugs in Emergency Medical Services in the Netherlands," the study concluded that the nasal plugs are an effective adjunct in the prehospital treatment of severe and uncontrolled epistaxis — with an 88% success rate, even in patients on blood thinners or with clotting disorders.

Supporting research from a multicenter randomized trial conducted in the Czech Republic (1999–2000) further validated oxidized cellulose across 200+ patients in multiple surgical settings — including maxillofacial, thoracic, and abdominal surgery. The trial found a statistically significant reduction in bleeding (p<0.001) when oxidized cellulose was used, with no adverse events reported.

How Nampons™ stop the bleed

When applied to a wound, it produces several effects.  First, the oxidized cellulose in Nampons® physically retards blood flow, slowing the bleed.  In addition, the SMOC™ technology in Nampons™ provides a surface or scaffold for proteins and cells in the blood to bind to and interact with, thereby promoting faster blood clotting.

Secondly, SMOC™ absorbs water and swells to form a gel-like structure.  This, combined with the binding of large proteins and cells in the blood, effectively creates a "plug" that acts as a physical barrier to bleeding.

Lastly, SMOC™ activates platelets in the blood.  These activated platelets aggregate, significantly reducing blood clotting time and thereby stopping the bleeding.

Nampons vs tissues — oxidized cellulose clotting comparison

Faster Than Tissues. Clinically Proven.

Tissues and cotton don't stop nosebleeds — they just absorb blood while you wait. Nampons™ work differently. The active oxidized cellulose clotting agent triggers your body's natural clotting response the moment it contacts blood.

In a peer-reviewed human clinical study published in BMC Surgery (Wenner et al., 2015), oxidized cellulose was compared head-to-head against standard cotton/viscose wound pads and five other hemostatic dressings. Oxidized cellulose achieved the fastest coagulation onset of all seven — averaging just 2.47 minutes. Standard wound pads showed no meaningful hemostatic effect. Untreated wounds on anticoagulants can bleed for 20 minutes or longer.

That's the difference between stuffing tissues in your nose and hoping for the best — and actually stopping the bleed.
