McKesson Cotton Unna Boot with Zinc Oxide — 4" x 10 Yards, Non-Hardening Paste, Preservative-Free

Non-hardening zinc oxide paste. Thread-locked cotton gauze. Stays moist to support healing throughout the full wear period. The McKesson Cotton Unna Boot (#2067) is a clinical-grade compression bandage of 100% cotton gauze evenly impregnated with a non-hardening zinc oxide paste — delivering sustained venous ulcer compression therapy for actively ambulatory patients. The zinc oxide paste maintains a consistent moist, semi-solid consistency throughout the wear period, keeping the wound environment conducive to healing without the hardening or caking that compromises traditional gelatin-based formulations. Non-raveling, thread-locked gauze construction prevents loose threads from entering the wound, and the preservative-free formula reduces the risk of chemical sensitivity in patients receiving ongoing Unna boot therapy. Latex-free. Single-use. Individually packaged in an easy-to-open vacuum-sealed pouch. Sold each or by the case of 12.

✔ Non-Hardening Zinc Oxide Paste — Stays Moist, Flexible & Comfortable ✔ Thread-Locked Cotton Gauze — No Raveling, No Wound Entanglement ✔ Preservative-Free — Reduced Sensitivity Risk ✔ Latex-Free ✔ Vacuum-Sealed Pouch — Moisture Preserved Until Use

Product Details

Features & Benefits

• Non-Hardening Zinc Oxide Paste — McKesson's Unna Boot is impregnated with a non-hardening zinc oxide paste that stays moist and pliable throughout the full wear period — typically 5 to 7 days. Unlike traditional Unna boots made with gelatin-based paste that can harden and cake with body heat and movement, the McKesson zinc oxide formulation remains flexible and comfortable against the skin, allowing natural ambulatory movement without the rigid cast-like structure that can cause patient discomfort and pressure injury over bony prominences
• Zinc Oxide — Wound-Supportive Properties — Zinc oxide is the active impregnation agent, providing a moist wound environment that supports healing, helps manage exudate, and delivers mild anti-inflammatory and skin-barrier properties at the wound surface. Zinc oxide also helps dry the oozing and weeping associated with conditions such as venous ulcers, eczema of the leg, poison ivy, poison oak, and poison sumac
• Thread-Locked Non-Raveling Gauze — The cotton gauze uses a thread-locked weave that prevents individual threads from raveling or pulling away from the bandage fabric during application, wear, and removal. This eliminates the risk of loose gauze fibers becoming embedded in wound tissue or adhering to granulating wound beds — a clinically significant concern with standard gauze in Unna boot applications
• Preservative-Free — No preservatives in the zinc oxide paste reduces the risk of contact sensitivity or chemical irritation reactions in patients receiving repeated or long-duration Unna boot therapy — particularly important for patients with chronic venous disease who require ongoing weekly compression dressing changes
• Latex-Free — Not made with natural rubber latex — safe for patients and clinicians with latex sensitivity or allergy, and appropriate for latex-free clinical protocols
• Vacuum-Sealed Pouch — Each roll is individually packaged in an easy-to-open vacuum-sealed pouch that preserves paste moisture content from manufacture to the point of use — ensuring the bandage performs as expected at the time of application, with no drying or paste degradation in storage
• Single Use — Designed for single-use disposal — supports infection control protocols and prevents cross-contamination between patients

Clinical Indications

• Venous stasis leg ulcers — ambulatory compression therapy
• Lymphatic edema of the lower extremity
• Thrombophlebitis — supportive compression
• Eczema of the leg and chronic lower extremity dermatitis
• Varicose ulcers requiring protection and support
• Minor sprains, strains, and fractures of the foot and ankle
• Skin grafts on burn wounds — protective compression
• Poison ivy, poison oak, and poison sumac — oozing and weeping

Contraindications: Do not use in patients with known hypersensitivity to zinc oxide or product components. Unna boots are not intended for non-ambulatory patients. Assess arterial circulation before application — do not apply to patients with significant arterial insufficiency. Application and change schedule must be directed by a qualified clinician.

McKesson Unna Boot vs. Primer Unna Boot — Which Is Right for You?

Bottom line: Both deliver the same core non-hardening zinc oxide compression therapy. The Primer adds a finished edge and wetness indicator — useful in high-volume wound care clinics where those features streamline clinical workflow. McKesson 2067 is the straightforward, high-quality standard choice for venous compression management across clinical and home health settings.

Application Overview

1. Cleanse and prepare the wound and periwound skin per facility or clinician protocol
2. Beginning at the base of the toes, apply the Unna Boot in a spiral or figure-eight wrap, working up the leg to just below the knee
3. Apply with even, moderate tension — overlap each layer by approximately 50% for consistent paste distribution and compression
4. Cover the Unna Boot with a secondary cohesive or short-stretch bandage to secure the boot and complete the compression layer
5. Change per clinician order — typically once or twice per week, or sooner if the dressing becomes saturated, loose, or if the patient reports increased pain or discomfort

Important: Unna boot therapy requires clinical assessment before application. Application and change frequency must be directed by a qualified wound care clinician or healthcare professional.
