How do Wound dressing, Bandage compare side by side?
The table below compares Wound dressing, Bandage across 10 procurement-relevant dimensions, from what fda says it is through source.
Side-by-side comparison
| Dimension | Wound dressing | Bandage |
|---|---|---|
| What FDA says it is | Hydrophilic wound dressing: "a sterile or non-sterile device intended to cover a wound and to absorb exudate" (21 CFR 878.4018). Occlusive wound dressing: a device "intended to cover a wound, to provide or support a moist wound environment, and to allow the exchange of gases" (21 CFR 878.4020). | Elastic bandage: "a long flat strip or a tube of elasticized material that is used to support and compress a part of a patient's body" (21 CFR 880.5075). |
| Main job in the definition | Cover the wound; absorb exudate (hydrophilic) or support a moist wound environment with gas exchange (occlusive). | Support and compress a body part (elastic bandage). |
| Materials named | Hydrophilic: nonresorbable materials such as cotton, cotton derivatives, alginates, dextran and rayon. Occlusive: synthetic polymer such as polyurethane, with or without an adhesive backing. | Elastic bandage: elasticized material, as a flat strip or a tube. Adhesive bandage: a strip of fabric or plastic coated on one side with an adhesive. |
| Sterility wording in the definition | Both dressing definitions read "sterile or non-sterile". | The elastic-bandage and adhesive-bandage definitions do not state sterility. The liquid bandage definition does: "a sterile device". |
| FDA classification | Class I (general controls) for both. | Class I (general controls) for elastic, adhesive and liquid bandages. |
| Premarket notification | Exempt from 510(k), subject to the limitations in 21 CFR 878.9. The sections exclude dressings with added drugs such as antimicrobial agents, added biologics such as growth factors, or animal-derived materials. | Elastic and adhesive bandages are exempt, subject to the limitations in 21 CFR 880.9. A liquid bandage is exempt only when used solely as a skin protectant. |
| Where the two words overlap | An adhesive bandage "may include a pad of surgical dressing without a disinfectant" (21 CFR 880.5240), so one product can contain a dressing. | The same section describes the adhesive bandage as a device used "to cover and protect wounds". A liquid bandage is defined as covering an opening in the skin or serving "as a dressing for burns" (21 CFR 880.5090). |
| Does it need the other one? | The regulations read here do not say a dressing must be paired with a bandage. A dressing with an adhesive backing (21 CFR 878.4020) carries its own attachment. | An adhesive bandage can include its own dressing pad (21 CFR 880.5240), so it does not need a separate dressing. |
| When this is the word you need | Use "dressing" when you mean the material that covers the wound and absorbs exudate or supports a moist wound environment. | Use "bandage" when you mean a strip or tube that supports or compresses a body part, or an adhesive strip that may carry a dressing pad. |

Common questions
Common questions about Wound dressing vs Bandage
Is a bandage the same as a dressing?
+
No. FDA defines a hydrophilic wound dressing as a device intended to cover a wound and absorb exudate (21 CFR 878.4018), and an elastic bandage as a strip or tube used to support and compress a body part (21 CFR 880.5075). The terms overlap in products such as the adhesive bandage, which may include a pad of surgical dressing (21 CFR 880.5240).
Is a Band-Aid a dressing or a bandage?
+
FDA's adhesive bandage definition (21 CFR 880.5240) describes a strip of fabric or plastic coated on one side with an adhesive that may include a pad of surgical dressing, so a product of that type combines a bandage strip and a dressing pad.
Does a dressing need a bandage?
+
The regulations read here do not say so. An occlusive wound dressing can have an adhesive backing (21 CFR 878.4020), and an adhesive bandage can include its own dressing pad (21 CFR 880.5240). This is general product information, not medical advice; follow the product's instructions for use and a clinician's guidance.
Are dressings and bandages regulated differently by FDA?
+
Each product type has its own section. Hydrophilic and occlusive wound dressings, elastic bandages and adhesive bandages are all Class I and exempt from 510(k) subject to the stated limitations; a liquid bandage is exempt only when used solely as a skin protectant.
