Mölnlycke Exufiber Ag+ Gelling Fiber Dressing — Hydrolock Technology, Silver Sulfate, Up to 7-Day Wear

Transforms into gel. Locks fluid in. Removes in one piece. Mölnlycke Exufiber Ag+ is a sterile non-woven antimicrobial gelling fiber dressing made from highly absorbent polyvinyl alcohol fibers impregnated with silver sulfate — providing rapid, sustained antimicrobial action against a broad range of Gram-negative and Gram-positive bacteria, including MRSA and VRE. Exufiber Ag+ features Hydrolock® technology — a fiber construction that packs fibers tightly to lock absorbed exudate, blood, and bacteria securely within the dressing, reducing the risk of leakage and periwound maceration under compression and during wear. Upon contact with wound exudate, the dressing transforms into a cohesive gel that supports a moist wound healing environment and maintains sufficient wet tensile strength to be removed in one piece at dressing change — reducing the risk of fiber residue in the wound. Kills 99% of fungus within 24 hours (in vitro). May reduce wound odor. May be left in place for up to 7 days. Available in ribbon and four pad sizes. Sold each, by the box, or by the case.

Product Details

⚠ Contraindications: Exufiber Ag+ should not be used on dry wounds or full-thickness burns. Do not use in patients with known sensitivity to silver or polyvinyl alcohol. If the dressing dries out and is difficult to remove, moisten per clinical practice and allow to soak until it lifts easily. Do not use in direct contact with exposed tendons, bones, or joints without clinical guidance.

Features & Benefits

• Hydrolock® Technology — Superior Fluid Retention — Hydrolock is Mölnlycke's proprietary fiber construction in which the polyvinyl alcohol fibers are packed tightly together, leaving less interstitial space for fluid to flow freely within the dressing. When exudate is absorbed, it swells the fibers and is locked securely in place rather than pooling and potentially leaking at the dressing edges. Independent retention testing demonstrates Exufiber Ag+ retains significantly more fluid under compression than conventional gelling fiber dressings — reducing the risk of periwound maceration and dressing leakage in high-exudate wound environments
• Silver Sulfate — Rapid Broad-Spectrum Antimicrobial Action — Silver sulfate is the active antimicrobial agent in Exufiber Ag+, delivering rapid action against a broad range of Gram-negative and Gram-positive bacteria upon contact with wound exudate. Antimicrobial protection is sustained for up to 7 days (in vitro), providing continuous coverage throughout the full wear period without requiring daily dressing changes — reducing clinician time, patient discomfort, and dressing costs compared to daily antimicrobial dressings
• Kills MRSA, VRE & 99% of Fungus Within 24 Hours — Exufiber Ag+ is effective against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), and has been proven to kill 99% of fungus within 24 hours of application (in vitro) — addressing the polymicrobial wound environment typical of chronic wounds, diabetic foot ulcers, and pressure injuries
• Transforms Into Cohesive Gel — Moist Wound Healing — Upon contact with wound exudate, Exufiber Ag+ transforms from a fiber dressing into a soft, cohesive gel. This gel state supports a moist wound healing environment at the wound interface — the standard of care for wound bed preparation — while maintaining the structural integrity needed for clean, one-piece removal
• High Wet Tensile Strength — One-Piece Removal — A key clinical differentiator of Exufiber Ag+ is its high wet tensile strength — the dressing maintains structural cohesion after gelling, so it can be grasped and removed in a single piece rather than fragmenting and leaving fiber residue in the wound. Residue left in the wound from conventional fiber dressings can impede healing and cause wound bed trauma during removal. One-piece removal also simplifies the dressing change procedure and reduces patient discomfort
• High Absorption — Manages Medium to Heavy Exudate — The polyvinyl alcohol fiber construction combined with Hydrolock technology provides high fluid uptake capacity appropriate for medium to heavily exuding wounds — including infected chronic wounds, post-surgical wounds with drainage, and wounds under compression producing elevated exudate
• Compatible with Compression Therapy — Exufiber Ag+ maintains its absorption and retention performance even under the pressure of compression bandaging — making it suitable for venous leg ulcers and other lower extremity wounds managed with compression systems
• Compatible with Mepilex Border with Safetac — Exufiber Ag+ can be used as a primary wound contact layer in combination with Mölnlycke's Mepilex Border foam dressing as the secondary cover — a clinically tested combination for management of exuding wounds requiring both antimicrobial contact layer coverage and absorbent foam secondary protection
• May Reduce Wound Odor — The antimicrobial action of silver sulfate against the bacterial bioburden that causes malodor may reduce the offensive wound odor associated with infected and colonized chronic wounds — an important quality-of-life consideration for patients with malignant wounds, diabetic foot ulcers, and long-standing pressure injuries
• Up to 7-Day Wear — Sustained antimicrobial action and high retention capacity allow Exufiber Ag+ to remain in place for up to 7 days, reducing dressing change frequency and associated clinical time, patient discomfort, and supply costs — change when saturated or clinically indicated before the 7-day maximum

Clinical Indications

• Venous leg ulcers and foot ulcers — including infected and critically colonized wounds
• Diabetic foot ulcers — medium to heavy exudate with infection or colonization risk
• Pressure injuries (pressure ulcers) — Stages II–IV with exudate
• Post-surgical wounds with drainage — including dehisced surgical wounds
• Donor sites — for skin graft harvest
• Partial thickness burns
• Malignant and oncology wounds — where antimicrobial and odor management are priorities
• Chronic wounds with signs of infection or critical colonization
• Tunneling wounds and sinus tracts — ribbon form (603420)
• Dermal lesions with moderate to heavy exudate

Contraindications: Do not use on dry wounds or full-thickness burns. Not for use with known sensitivity to silver or polyvinyl alcohol. Not for direct contact with exposed tendons, bones, or joints without clinical guidance.

Exufiber Ag+ vs. Standard Gelling Fiber Dressings

Application Overview

1. Cleanse the wound per clinical protocol before application
2. Select the appropriate size — dressing should cover the wound bed and overlap onto surrounding skin by approximately 1 cm; cut to fit if needed
3. For ribbon use (603420): loosely pack into tunneling wound or cavity — do not pack tightly; leave a tail visible at the wound surface for easy retrieval
4. Apply Exufiber Ag+ directly to the wound bed as the primary dressing
5. Cover with an appropriate secondary dressing — Mepilex Border with Safetac or other foam secondary as clinically indicated
6. Secure with tape or compression bandaging as appropriate
7. Change when saturated, when secondary dressing is full, or per clinician order — up to a maximum of 7 days
8. If dressing has dried and is difficult to remove, moisten with sterile saline or wound cleanser and allow to soak before removal

Frequently Asked Questions

What is Hydrolock technology and how does it make Exufiber Ag+ different?
Hydrolock is Mölnlycke's proprietary fiber construction in which the polyvinyl alcohol fibers are packed tightly together rather than loosely woven. This tight packing leaves less interstitial space for absorbed fluid to flow back out, locking exudate, blood, and bacteria securely within the dressing structure. In independent fluid retention testing, Exufiber Ag+ retains significantly more fluid under compression than conventional gelling fiber dressings — meaning less leakage at the dressing edges, less periwound maceration, and more reliable protection through the full wear period. Standard gelling fiber dressings absorb well but do not retain as effectively under pressure.

What is the difference between Exufiber Ag+ and standard Exufiber (without silver)?
Standard Exufiber uses the same Hydrolock polyvinyl alcohol fiber construction and transforms into gel upon contact with exudate, but it does not contain silver sulfate. It is appropriate for medium to highly exuding wounds without signs of infection or critical colonization — where the goal is exudate management and moist wound healing without antimicrobial intervention. Exufiber Ag+ adds silver sulfate for broad-spectrum antimicrobial action against bacteria including MRSA and VRE, antifungal activity, and potential odor reduction. Choose Exufiber Ag+ when the wound shows signs of infection, critical colonization, elevated bacterial burden, or odor. Choose standard Exufiber for clean exuding wounds where antimicrobial therapy is not clinically indicated.

Why does Exufiber Ag+ remove in one piece when other fiber dressings fragment?
Exufiber Ag+ maintains high wet tensile strength after gelling — meaning even after the dressing has absorbed exudate and transformed into gel, the fiber structure retains enough physical cohesion to be grasped and removed as a single intact piece. Conventional gelling fiber dressings made from sodium carboxymethylcellulose (CMC) or other materials can lose structural integrity after absorbing fluid, causing them to fragment during removal and leave fibers in the wound bed. Retained fibers can act as a foreign body, impede healing, and increase infection risk. The polyvinyl alcohol material and Hydrolock construction of Exufiber Ag+ preserve the dressing's physical integrity through the wear period for clean, atraumatic single-piece removal.

Can Exufiber Ag+ be used under compression bandaging?
Yes — Exufiber Ag+ is specifically designed to maintain its absorption and retention performance under compression. The Hydrolock fiber construction keeps absorbed fluid locked within the dressing even when external pressure from compression bandaging is applied — making it appropriate for venous leg ulcers, mixed arterial-venous ulcers, and other lower extremity wounds managed with compression systems. Many conventional gelling fiber dressings lose retention capacity under compression, allowing exudate to be expressed back onto the periwound skin.

How does the ribbon form (603420) differ from the pad sizes?
The ribbon (0.8 x 17.7 inches / 2 x 45 cm) is specifically designed for packing tunneling wounds, sinus tracts, fistulas, and deep cavity wounds where a flat pad cannot reach the base of the wound. Loose packing with the ribbon ensures antimicrobial contact with the wound walls throughout the cavity while managing exudate draining from depth. Leave a visible tail at the wound surface during packing to ensure the ribbon can be fully retrieved at dressing change. The pad sizes (603421–603424) are for open surface wounds and can be cut to fit wound dimensions without compromising performance.

What does "kills 99% of fungus within 24 hours" mean clinically?
This is an in vitro result — meaning it was demonstrated in laboratory testing conditions, not in a clinical trial. In vitro antimicrobial data indicates the dressing's capability under controlled conditions. Clinical results may vary depending on wound bioburden, exudate volume, wound type, and patient factors. The antifungal claim is clinically relevant for wounds at risk of fungal colonization, including immunocompromised patients, diabetic foot ulcers, and oncology wounds. Exufiber Ag+ is not a substitute for systemic antifungal therapy where systemic infection is present.

How long can Exufiber Ag+ stay in place?
Exufiber Ag+ may be left in place for up to 7 days. However, the dressing should be changed before 7 days if it becomes saturated, if exudate strikes through to the secondary dressing, if there are signs of wound deterioration, or if the patient reports increased pain. In practice, the actual wear time will depend on wound exudate volume — heavily draining wounds may require more frequent changes than the maximum wear time allows. The treating clinician determines the appropriate change frequency based on wound assessment.

Is Exufiber Ag+ sold individually or in bulk?
Exufiber Ag+ is available as individual units (each), by the box, or by the case — with quantities varying by size. Box quantities range from 5 to 10 per box depending on size; case quantities range from 20 to 60. Case purchasing provides the best per-dressing value for wound care clinics, home health agencies, and facilities with ongoing antimicrobial dressing programs.
