McKesson Calcium Alginate Dressing, 4 x 4¾ inch

McKesson Calcium Alginate Dressing, 4 x 4¾ inch

The McKesson Calcium Alginate Dressing is a highly absorbent, nonocclusive wound dressing designed for wounds that produce moderate to heavy drainage. Made from naturally derived alginate fibers, it's ideal for caregivers, clinicians, and home users managing pressure injuries, surgical wounds, leg ulcers, and other exuding wounds where effective moisture control supports healing.

When this calcium alginate dressing comes into contact with wound fluid, its fibers form a soft, conforming gel that helps maintain a moist wound environment while absorbing moderate to heavy exudate. Its optimal gelling profile helps the dressing avoid sticking to the wound bed and maintain its physical integrity, so it can typically be removed in one piece for gentler dressing changes. The alginate may also help control minor bleeding, and it can be used to fill or pack dead space in deeper wounds.

This dressing measures 4 x 4¾ inches and is sterile, and it may be trimmed to fit your wound dimensions. Because alginate is not self-adhering, a secondary dressing is needed to hold it in place and protect the wound from outside contaminants. It's available in a single unit, a box of 10, or a case of 100—select your preferred option below to order the right quantity for your needs.

Frequently Asked Questions

Q: What type of wounds is this alginate dressing best for?
A: It's designed for wounds with moderate to heavy exudate, such as pressure injuries, leg and diabetic ulcers, surgical wounds, and donor sites. It may also help control minor bleeding.

Q: Do I need a secondary dressing?
A: Yes. Calcium alginate is nonadhesive, so a secondary dressing—such as a foam, film, or gauze cover—is required to hold it in place and protect the wound from contaminants.

Q: Can I cut the dressing to fit my wound?
A: Yes, the dressing may be trimmed to match your wound dimensions, and it can also be used to fill or pack dead space in deeper wounds.

Q: Is this dressing sterile?
A: Yes, the McKesson Calcium Alginate Dressing is sterile and packaged for single use.

Q: How often should the dressing be changed?
A: Change frequency depends on the amount of drainage and your provider's guidance. Alginate dressings are typically changed as they become saturated; follow your healthcare professional's instructions.
