KerraCel Ag Silver Gelling Fiber Dressings

KerraCel Ag combines the fluid-handling strength of carboxymethyl cellulose (CMC) gelling fiber with the antimicrobial action of ionic silver, making it a go-to dressing for moderately to heavily exuding wounds where infection is a concern. As exudate is absorbed, the fibers transform into a soft, cohesive gel that conforms to the wound bed, helps maintain a moist healing environment, and lifts away cleanly at dressing changes with minimal trauma to fragile tissue.

The dressing we carry — KerraCel Ag 6" x 6" square, sterile, non-adhesive (CWL1159) — suits pressure injuries, diabetic foot ulcers, venous leg ulcers, surgical wounds healing by secondary intention, and donor or graft sites. Because it's non-adhesive, it relies on a secondary dressing or wrap to hold it in place, which gives clinicians flexibility over compression and fixation. The silver stays active within the dressing while it manages exudate, supporting bacterial control without the mess of frequent replacement.

Buyers most often ask how long KerraCel Ag can stay in place and how it differs from plain gelling fiber. Wear time depends on exudate volume — it can remain for several days on lighter wounds and should be changed sooner when saturated — and the key difference from a non-silver CMC dressing is the added antimicrobial layer for wounds showing signs of critical colonization or infection. The 6" x 6" size can be cut or folded to fit smaller or irregular wounds.

If you're comparing silver dressing options, it's worth looking at other antimicrobial lines we stock, including Algidex Ag and our broader Ag+ silver wound care range, to match the delivery format to your wound and workflow.
