Short answer
Vashe is an FDA-cleared wound cleansing and irrigation solution formulated with pure hypochlorous acid (HOCl) in a saline base. Regulated as an unclassified medical device under product code FRO, it mechanically cleanses, moistens, and debrides acute and chronic wounds, loosens slough and biofilm, and inhibits microbial contamination without damaging healthy regenerating tissue.
Definition and scope
As described in official regulatory filings on 2026-11-11, Vashe Wound Solution is a non-cytotoxic wound cleanser and irrigation fluid manufactured by Urgo Medical North America (originally developed by PuriCore Inc.). The solution is cleared by the U.S. Food and Drug Administration (FDA) through premarket notification 510(k) clearances, notably K131848 and the updated Vashe Plus Antimicrobial Solution clearance under K253665 (cleared August 11, 2026).
The FDA classifies Vashe under product code FRO (Dressing, Wound, Drug) within the General and Plastic Surgery review panel. In regulatory status, it is an unclassified medical device governed by 21 CFR Part 820 quality management system regulations. Cleared for prescription (Rx) and over-the-counter (OTC) use, Vashe is indicated for cleansing, irrigating, moistening, debridement (slough removal), and clearing foreign material, debris, and microorganisms from acute and chronic wound types. Cleared indications include Stage I through IV pressure injuries, diabetic foot ulcers, venous stasis ulcers, post-surgical wounds, first- and second-degree burns, donor and graft sites, and catheter exit sites, as well as lubricating absorbent dressings prior to removal.
How it works or how it is used in practice
As confirmed by primary laboratory and regulatory documentation on 2026-11-11, Vashe relies on pure hypochlorous acid (HOCl) chemistry combined with mechanical fluid action:
- HOCl Chemical Action: Hypochlorous acid is an endogenous oxidant produced naturally by human neutrophils during phagocytosis. Formulated at an acidic-to-neutral pH (approximately 5.5), neutral HOCl molecules predominate over charged hypochlorite ions (OCl-). Carrying no electrical charge, HOCl penetrates bacterial membranes and extracellular polymeric substance (EPS) matrices of biofilms more readily than charged hypochlorite.
- Preservative Efficacy: Under USP <51> Category 2 testing documented in FDA clearance K253665, the formulation achieved greater than 4.5-log reduction against challenge pathogens (Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus brasiliensis) across a 9-month shelf life and simulated 7-day multi-dispensing clinical use.
- Biofilm Disruption: Sourced evaluations in Plastic and Reconstructive Surgery confirmed that stabilized HOCl solutions disrupt and reduce bacterial and fungal biofilms within 1 to 10 minutes.
- Mechanical Debridement: Unlike traditional antiseptics for wound care that depend on chemical toxicity, Vashe functions mechanically. Fluid motion lifts exudate, cellular debris, and loosened necrotic tissue away from the wound bed.
- Clinical Practice Application: Healthcare staff apply the solution via direct irrigation, pulsed lavage, or by soaking non-woven gauze pads placed on the wound bed for 5 to 10 minutes prior to debridement, or as instillation fluid in negative-pressure wound therapy (NPWT) systems.
Types or related concepts
As evaluated against primary FDA records on 2026-11-11, wound cleansers vary fundamentally by active chemistry, tissue toxicity, and mechanism:
| Solution Class & Product | Active Chemistry | Target pH | Cytotoxicity Profile | Regulatory & Billing Identity |
|---|---|---|---|---|
| Pure Hypochlorous Acid (Vashe, Vashe Plus) |
Pure HOCl in saline base | 5.0 to 6.5 | Non-cytotoxic (ISO 10993-5 Grade ≤ 2; minimal tissue reaction in porcine models) | FDA Code FRO; 510(k) K131848 / K253665; HCPCS A6260 |
| HOCl Preserved Cleanser (Puracyn) |
HOCl / Sodium hypochlorite mix | 6.2 to 7.0 | Non-cytotoxic to fibroblasts | FDA Code FRO; 510(k) K172622; HCPCS A6260 |
| Sodium Hypochlorite (Dakin’s Solution, Anasept) |
Sodium hypochlorite (NaOCl) | Alkaline (9.0 to 11.0) | Dose-dependent cytotoxicity to healthy granulation tissue and fibroblasts | Topical drug antiseptic / 510(k) K073547; HCPCS A6260 |
| Polyhexanide & Betaine (Prontosan) |
0.1% PHMB surfactant + undecylenamidopropyl betaine | 5.5 to 7.0 | Low tissue toxicity; surfactant lowers surface tension to loosen slough | FDA Code FRO; 510(k) K163430; HCPCS A6260 |
| Standard Saline (Normal Saline Solution 0.9%) |
0.9% Sodium Chloride in purified water | 4.5 to 7.0 | Physiologic; non-toxic, but provides no preservative or active biofilm loosening | FDA Code FRO / 21 CFR 880.5440; HCPCS A4216 or A6260 |
Following wound cleansing and debridement, clinicians frequently dress the wound bed with secondary antimicrobial wound dressings or protective barriers according to clinical protocol.
Where it matters for labs, clinics or supply decisions
As confirmed by manufacturer specifications and hospital supply reviews on 2026-11-11, materials management teams manage Vashe across several operational parameters:
- Packaging and Volumes: Vashe and Vashe Plus are packaged in polyethylene terephthalate (PET) containers with polypropylene caps and induction seals. Standard clinical sizes include 118 mL (4 oz), 250 mL (8.5 oz), 475 mL (16 oz), and 1000 mL (33.8 oz) pour bottles.
- Storage Temperature: HOCl stability depends on temperature control. Cleared labeling specifies storage between 5°C and 25°C (41°F to 77°F). The solution must not be frozen and should be kept away from direct sunlight and radiant heat.
- Open-Bottle Multi-Use: USP <51> preservative testing supports multi-use dispensing over 7 days once opened when clean handling is maintained. Facilities should date opened bottles per facility timing rules.
- Hardware Compatibility: Testing under K253665 confirmed compatibility with polyvinyl chloride (PVC) and medical-grade silicone tubing and vented spikes for up to 4 hours of continuous contact without degradation or drop in Available Free Chlorine (AFC).
- Billing and Reimbursement: Under HCPCS, Vashe is billed under code A6260 (Wound cleansers, any type, any size).
Common misunderstandings
As documented in clinical guidelines and FDA review summaries on 2026-11-11, healthcare personnel frequently encounter three key misconceptions:
- Misunderstanding 1: Confusing Pure HOCl with Dilute Bleach. Dakin’s solution consists of alkaline sodium hypochlorite (NaOCl, pH >9.0), producing hypochlorite ions (OCl-) that demonstrate in vitro cytotoxicity to fibroblasts. Conversely, Vashe is pure hypochlorous acid (HOCl) at physiological pH 5.5, which is biocompatible, non-stinging, and non-cytotoxic to healthy tissue.
- Misunderstanding 2: Assuming Vashe Replaces Systemic Antibiotics. Vashe is an FDA-cleared wound cleanser device, not a systemic antimicrobial drug. While HOCl disrupts local wound bioburden, it does not treat invasive systemic infections or cellulitis.
- Misunderstanding 3: Treating Vashe Identically to Normal Saline. While 0.9% saline provides safe irrigation, it lacks antimicrobial preservative properties once unsealed and does not actively loosen biofilm. Vashe actively loosens slough and provides multi-day preservative stability against contamination.
Frequently asked questions
What is Vashe used for?
Vashe is used under healthcare supervision to clean, irrigate, moisten, and debride acute and chronic wounds, including pressure ulcers, diabetic foot ulcers, venous ulcers, surgical wounds, burns, and donor sites, as well as to lubricate dressings for gentle removal.
Does Vashe require rinsing after application?
No. Vashe is a no-rinse solution formulated at skin-neutral pH (approx. 5.5). Because it is non-cytotoxic and biocompatible, it can remain on the wound bed without rinsing before secondary dressings are placed.
What is the active ingredient in Vashe?
The active ingredient is pure hypochlorous acid (HOCl) formulated in an aqueous sodium chloride saline base. HOCl functions as an antimicrobial preservative that prevents microbial growth in the bottle and assists in the physical loosening of slough and biofilm.
What is the HCPCS billing code for Vashe?
Vashe is categorized under HCPCS code A6260 (Wound cleansers, any type, any size) across all container volumes.
What are the storage conditions for Vashe bottles?
Vashe bottles should be stored at controlled room temperature between 5°C and 25°C (41°F to 77°F). Do not freeze, and keep away from prolonged exposure to direct sunlight and high heat sources.
