General product information from FDA records and the manufacturer’s instructions for use. It is not medical advice; wound care decisions belong to a health care professional.
Short answer
Silverlon is a brand of single-use, non-adherent wound dressings made from knitted nylon plated with silver. Moisture activates the silver, and the dressing is used as a primary dressing for up to seven days. Argentum Medical holds the FDA 510(k) clearances; the FDA lists the product code as “Dressing, Wound, Drug” (FRO), device class unclassified.
Definition and scope
The name covers a product family, not one item. Per the manufacturer’s product page, the range includes contact dressings, island dressings, pads, wraps, negative pressure dressings, IV/catheter dressings, adhesive strips, digit sleeves, burn gloves, torso dressings and a combat medic format. The FDA summary for K241225 describes rectangular, chest/trunk apron, wrap and glove configurations.
The instructions for use (IFU) describe the base material as knitted nylon plated with about 99% elemental silver plus 1% silver oxide. A separate silver gel, Silversept, is sold by the same company; it is a different product and is not covered by the dressing clearances discussed here.
How it is used in practice
The FDA 510(k) summary for K241225 describes a single-layer, non-adherent antimicrobial barrier dressing. Silver ions are activated by moisture and act on bacteria held in the dressing. It is a primary dressing, intended for up to seven days of use.
What are silver impregnated dressings used for in wounds?
For this product, the cleared indications (K241225) are split by label type. Over the counter: local management of superficial wounds, minor burns, abrasions and lacerations. Under prescription, for up to seven days: partial and full thickness wounds including traumatic and surgical wounds (donor and graft sites, incisions), first and second degree burns, dermal ulcers (pressure ulcers stage I to IV, venous stasis, arterial and diabetic ulcers), vascular access and peripheral IV sites, orthopedic external pin sites and wound drain sites. K241225 added decontaminated unroofed mustard-induced vesicant injuries, radiation dermatitis and acute cutaneous radiation injury with moist desquamation. The FDA summary states that K241225 expanded indications only; the product is identical to the one cleared in K221218.
Other silver formats are covered in silver wound care dressings, collagen silver dressings and the calcium alginate versus silver alginate comparison.
Regulatory ledger: Silverlon clearances in openFDA
A search of the openFDA 510(k) database (read 2026-11-07) for the device name Silverlon returns more clearances than are listed here (earlier Argentum Medical submissions from 1998 to 2018 are omitted). The table shows selected clearances only, covering the original contact dressing and strip formats, the island and negative pressure formats, and the 2019 to 2024 submissions.

The FDA classification record for product code FRO lists “Dressing, Wound, Drug”, device class unclassified, with no regulation number. The K241225 summary places it in the General and Plastic Surgery panel. Preclinical data in that summary came from a GLP swine study (40 swine, 640 wounds) with 1% silver sulfadiazine on gauze as the comparator.
Label-reading checklist
- Prescription or over the counter. The IFU carries a federal-law prescription caution, and the 510(k) separates OTC indications from prescription indications.
- Duration. The cleared labeling is for up to seven days.
- Contraindication. The IFU lists sensitivity to silver or nylon as a contraindication.
- Primary dressing. The 510(k) describes it as a primary dressing.
- MR status. The IFU has an MR Conditional section.
- Biocompatibility. The IFU cites ISO 10993 testing for cytotoxicity, sensitization and intracutaneous reactivity.
- Which clearance. Match the product format to its 510(k) number; the negative pressure dressing is under a separate product code.
Where it matters for labs, clinics and supply decisions
The useful distinction for research and supply staff is between brand, format and clearance. The brand name alone does not show which indications or product code apply, so records should capture the exact product name, the 510(k) number and the IFU revision (the contact dressing IFU read for this page is Rev F). See also what a medical dressing is and non-adherent dressings.
Common misunderstandings
- “FDA cleared means FDA approved.” The FDA clearance letter states that substantial equivalence does not mean FDA approval of other requirements.
- “Silver dressing and silver gel are the same.” Silversept gel is a separate product from the Silverlon dressings.
- “Silver has no limits.” The IFU notes that some studies report silver-resistant strains, and lists sensitivity as a contraindication.
