Description: Allevyn Non-Adhesive Hydrocellular Polyurethane Dressing


  • Unique trilaminate structure
  • Non adherent wound contact layer
  • Highly absorbent central hydrocellular layer
  • Waterproof outer film layer
  • Non adhesive
  • Full range of sizes


Highly absorbent
In-vitro studies and clinical experience both demonstrate that Allevyn non-adherent dressings can stay in place for up to seven days.

This capacity results from a combination of properties:

  • The perforated wound contact layer allows even viscous exudate to pass into the dressing.
  • The hydrocellular core of the dressing absorbs and retains liquid in its microscopic structure.
  • The breathable outer surface of the dressing allows excess moisture to evaporate away from the dressing.

The result is the creation of a wound environment, which allows healing to progress.

Allevyn dressings have a polyurethane wound contact layer which prevents adherence to a full range of wound types.

Helps create and maintain a moist wound environment
The outer, pink layer used on Allevyn dressings is a breathable film layer. This allows the formation and maintenance of a moist wound environment at the wound surface, which helps prevent eschar formation. The pink film is also waterproof and aids in the prevention of bacterial contamination.

Allevyn dressings are non-adhesive and are therefore recommended for wounds surrounded by sensitive skin, such as venous ulcers. The lack of adhesive allows the use of the most suitable retention method, for example, tape onto intact skin, appropriate bandaging or a film dressing such as Opsite®.

Easy to use
Allevyn dressings are conformable and can be cut to suit various wound shapes and locations. As Allevyn dressings absorb exudate, they may swell slightly, but do not leave debris in the wound. Dressing changes are therefore easier for the nurse and less traumatic for the patient; wound irrigation can be kept to a minimum. The progression of exudate through the dressing is visible through the pink top film.

Soft and cushioning
Allevyn dressings are soft and cushioning, providing excellent patient comfort.


  • Allevyn Hydrocellular Foam Dressing is indicated for exudate absorption and the management of partial to full thickness wounds. Some typical wounds are:
             Ulcers (venous, arterial, diabetic)
             Pressure Sores
             Donor Sites
             Surgical Incisions
             Surgical Excisions
             Burns (1st and 2nd degree)
  • Creation and maintenance of a moist wound environment. Moist wound environments have been established as optimal environments for the management of the wound.
  • Provides physical separation between the wound and external environments to assist in preventing bacterial contamination of the wound.


Do not use Allevyn dressings with oxidising agents such as hypochlorite solutions (e.g. Dakins) or hydrogen peroxide, as these can break down the absorbent hydrocellular component of the dressing.

Reddening of the skin around the wound has been reported rarely following the use of Allevyn dressings. In some cases this relates to irritation of fragile skin, in others, wound exudate remaining in contact with normal skin for prolonged periods may be the cause.

Infrequently, cases of sensitivity to the dressing have also been reported.

If reddening or sensitization occur, discontinue use and consult a healthcare professional.

Allevyn Hydrocellular Foam Dressing is not indicated for use on third degree burns.

Step 1

Choose a dressing to leave at least 1/2" margin around the wound. Peel open the paper pouch.

It is always important to sanitize your hands prior to dressing any wound. Sani hands antimicrobial hand wipes are pre-moistened hand wipes that cleanse and sanitize hands when soap and water are not available. The friction of the Sani hands wipe removes soil and bacteria and kills 99.99% of germs that helps reduce the risk of cross-contamination and the spread of infection.

Many of our customers have reported excellent results using Puracyn OTC (formerly named Microcyn OTC). Puracyn OTC is an innovative new approach to wound care promoting faster healing time. It is a non-irritating, pH-balanced wound cleanser for minor cuts, burns, irritations, and superficial abrasions of the skin.

After the wound has closed, proven scar treatments such as Cica-Care, Mepiform, or Kelo-Cote will improve the appearance of scars and prevent abnormal or excessive scar formation. Always consult your physician or wound care specialist before starting any wound care treatment program.

We also carry supplies for compression wrapping such as Comprilan, Elastoplast, and Jobst Cover-Roll.
