McKesson Unna Boot 4 or 3 Inches x 10 Yards w/ Zinc (Optional Calamine)

Who Wears a McKesson Unna Boot? Patients with chronic lower limb wounds such as venous ulcers or diabetic foot wounds use this gauze bandage to apply supportive compression therapy.

Why They Love It: It protects venous ulcers and diabetic foot wounds so that individuals can walk and participate in normal daily activities. The 10-yard roll creates adequate coverage and a custom fit by layering the gauze from the foot to the knee. The gauze naturally contours, providing low-level compression without fraying or sticking to the wound. Wearing the customized Unna boot provides support and comfort, and above all, it accelerates the healing process.¹

Wearing a McKesson Unna Boot is a simple way to manage chronic lower limb wounds such as diabetic or venous ulcers and promote healing so patients can get back on their feet. The inelastic gauze bandage is impregnated with nonhardening zinc oxide for compression therapy that encourages venous return and promotes healing. Other options include zinc oxide and soothing calamine to relieve itching as the wound heals. The 10-yard roll of gauze is stiff yet conformable to support muscles in the feet. This bandage with zinc oxide is known for its healing properties. It helps to keep bacteria out of the wound and maintains a moist wound bed. McKesson recommends a secondary cohesive bandage if additional compression or adhesion is needed.  

The Unna boot gauze is impregnated with a Zinc Oxide (ZnO) nonhardening paste to provide a soft bandage with healing properties. Zinc Oxide offers antimicrobial, anti-inflammatory, and antiseptic properties.² This addition encourages cell rejuvenation for wounds to heal and thrive in a healthy environment. ZnO also maintains a moist wound environment for another layer of supportive healing.

As the wound heals, itching is a typical sign of recovery. Calamine is another ingredient option for patients who want to boost the gauze's therapeutic properties with an anti-itch medication to help ease that itching discomfort associated with healing.

How often is an Unna Boot changed?
How often it's changed depends on how much the venous ulcer drains. Typically it is changed weekly or twice a week if there is a lot of exudate drainage.

How much compression does the Unna Boot bandage provide?
The Unna Boot gauze bandage provides approximately 18 to 24 mmHg of pressure.
Can you walk with an Unna boot?
Yes, walking and normal activities are allowed while wearing the Unna boot.

Are Unna boots helpful for treating other conditions than venous ulcers?
Yes. In addition to the conditions found in the indications section, the bandage infused with calamine is also helpful to prevent itching when the skin is inflamed from exposure to poison oak, poison ivy, or sumac. 

What are the contraindications?
Patients who are nonambulatory as well as those who have an allergy to zinc oxide or calamine.
