MicroLyte® Matrix is composed primarily of polyvinyl alcohol with a polymeric surface coating containing ionic and metallic silver and is indicated for management of all wounds.
• Absorbs wound fluid and transforms into a soft 100% bioresorbable gel that intimately contours to the underlying wound bed
• Maintains a physiologically moist microenvironment
• Low residual toxicity compared to other antimicrobial matrices
• Contains antimicrobial silver which kills bacteria in contact with the matrix
• Does not require pre-wetting prior to application
MicroLyte® Matrix is indicated for use on partial- and full-thickness wounds including pressure ulcers, venous stasis ulcers, diabetic foot ulcers, surgical wounds including donor sites, over debrided and grafted partial-thickness wounds, post-Mohs surgery, post-laser surgery, podiatry and wound dehiscence. Can also be used on traumatic wounds including first- and second-degree burns, abrasions, lacerations and skin tears.
Do not use on individuals who are sensitive to silver or who have had an allergic reaction to MicroLyte® Matrix or one of its components.
Warning: Frequent or prolonged use of this product may result in permanent discoloration of skin.
Warning: Avoid use with iodophor containing products that may reduce the effectiveness of silver in the dressing.
The wound should be inspected during cover dressing changes. Consult a health care professional if you see (a) signs of infection (increased pain, increased redness, wound drainage), (b) bleeding, (c) a change in wound color and/or odor, (d) irritation (increased redness and/or inflammation), (e) maceration (skin whitening), (f) hypergranulation (excessive tissue formation), (g) sensitivity (allergic reaction), (h) no signs of healing.
Secondary cover dressings should be used as stated in the "Directions for Use" section.
MicroLyte® Matrix should not be used with other wound care products other than those listed in the "Directions for Use" section without first consulting a health care professional.
This product contains <0.5 mg/in2 polyethylene glycol (400 Da)
For pressure ulcers, venous stasis ulcers, diabetic ulcers, first- and second-degree burns, donor sites, skin grafts and surgical wounds:
• Treatment of wounds listed above should be under the supervision of a health care professional.
• Appropriate supportive measures should be taken where indicated. For example, use of granulated compression in the management of venous leg ulcers, or pressure relief measures in the management of pressure ulcers, systemic antibiotics and frequent monitoring in the treatment of wound infection, control of blood glucose for diabetic ulcers, etc.
Store at room temperature (15°C-30°C, 59°F-86°F). Keep dry.

Clean the wound area using sterile saline solution. If the wound is dry, moisten it with sterile saline and remove excess saline with sterile gauze. Avoid contact with wet surfaces until placed on a moist wound bed. Cut MicroLyte® Matrix to size slightly larger than the wound. Multiple sheets can be used to tile the entire wound area. Apply MicroLyte® Matrix directly to wound bed. When placed on a moist wound bed, the dressing forms a soft conforming sheet. MicroLyte® Matrix should be used with a secondary cover dressing. Cover with a moisture retentive dressing, such as a film dressing, foam dressing, wet-to-dry gauze or other appropriate dressing. See individual cover dressing package inserts for complete instructions for use. All dressing site areas should be inspected daily.
Reapply MicroLyte® Matrix daily or up to every three days, depending on the wound and the healing progression, or when clinically indicated (e.g., leakage, excessive bleeding, increased pain).To reapply, carefully remove the secondary cover dressing. Gently irrigate wound with sterile saline to remove necrotic tissue. It is not necessary to remove any residual MicroLyte® Matrix observed during secondary cover dressing changes. Change the secondary cover dressing as needed or when MicroLyte® Matrix is re-applied. Duration of treatment depends on wound type and healing conditions.
