3M Nexcare Water Proof Bandages (65 x 25mm)

3M Nexcare Water Proof Bandages (65 x 25mm) is an individually wrapped adhesive plaster built from a thin, flexible polyurethane film with a medical-grade adhesive border, and a non-stick absorbent pad set at the centre for direct contact with the skin. The formulation is hypoallergenic and latex-free, and the film runs edge-to-edge around the pad to form a continuous seal rather than relying on a fabric strip with a fabric backing. It is sold over the counter as a general-sale item, without a prescription, in packs of 5 bandages of the 65mm x 25mm size.

Within the wider Nexcare waterproof range, this size sits at the compact end, intended for smaller everyday cuts, grazes, and blisters rather than larger surgical-style dressings, tattoo coverings, or the bigger transparent film formats also sold under the Nexcare name. Each bandage is individually sealed for hygiene until opened, and the product is a plain adhesive dressing with no active pharmaceutical ingredient in either the pad or the adhesive.

The outer layer is a continuous polyurethane film, a type of material that is permeable to water vapour and oxygen but impermeable to liquid water and bacteria — this is what allows the surface of the bandage to stay breathable while still keeping external moisture and contaminants out once it is fully applied. The medical-grade adhesive forms a complete border around the absorbent pad, so pressing the edges down firmly creates a continuous seal rather than leaving gaps at the corners. The pad itself has a non-stick facing designed to reduce fibre transfer and sticking to the skin underneath when the bandage is removed.

Clean and dry the surrounding skin before application, since the adhesive bonds best to a dry surface. Peel away the backing liner without touching the adhesive underside or the central pad, then position the pad directly over the area and press the adhesive edges down firmly, smoothing from the centre outward to remove any air pockets or wrinkles.

Replace the bandage with a fresh one if it lifts at the edges, becomes wet underneath, or is visibly soiled, and follow the wear-time guidance printed on the packaging. To remove, gently lift one corner and peel back slowly and low against the skin, supporting the surrounding skin with your other hand rather than pulling straight upward.

Not applicable — this is a medical device, not a medicine requiring dosing.

Use each bandage before the expiry date printed on the box. An unopened pack kept in suitable storage conditions should remain usable up to that date, but any bandage that has been opened, damaged, or exposed to moisture should not be kept for later use.

Store the pack in a cool, dry place away from direct sunlight and excess humidity, keeping unused bandages in their original individual wrapping until needed. Keep the box out of the reach of children.

• Common: Mild redness or irritation at the site of adhesive contact, particularly with prolonged wear or on sensitive skin.
• Common: Slight skin marking or a temporary imprint from the adhesive border after removal.
• Serious: Signs of an adhesive allergy such as spreading redness, blistering, or itching that extends beyond the contact area should be assessed by a doctor or pharmacist, and the bandage should be removed if this occurs.

• Not for use in anyone with a known allergy or hypersensitivity to acrylic adhesives or polyurethane film.
• Not intended for wounds that already show signs of infection, such as spreading redness, warmth, swelling, or discharge, without prior assessment by a doctor or pharmacist.
• Not suitable for deep puncture wounds, animal or human bites, or cuts that may require stitches — these need professional medical attention.

• Not applicable — this is a topical adhesive dressing applied to intact or minor broken skin, not a medicine that is swallowed or absorbed systemically.
• No interactions with oral or injectable medicines are known or expected from normal use of this product.
• No food interactions apply to this product.

• Dry the surrounding skin thoroughly before applying so the adhesive border bonds properly and doesn’t lift early.
• If trimming a bandage to size, round off the cut corners, as rounded edges lift less than sharp corners during normal movement.
• Keep a mix of bandages on hand for awkward spots like knuckles or heels, where a standard rectangular shape may not sit flat.
• Store the box in a dry cupboard rather than a humid bathroom shelf, as prolonged humidity can affect adhesive performance over time.
• Wipe oily or sweaty skin with a dry cloth immediately before application, since oil on the skin surface can reduce how well the adhesive border seals.
• Always check the expiry date on the box before opening a bandage, and discard any that are past this date.

Precautions: Use in children should be supervised by an adult, and the bandage should be checked periodically for lifting or soiling. Watch for early signs of an adhesive reaction, such as spreading redness or itching beyond the contact area, and remove the bandage if this occurs. Avoid repeated use over skin that is already irritated or broken in more than one small area without first checking with a pharmacist.

When to See a Doctor or Pharmacist: Speak to a doctor or pharmacist if the covered area becomes increasingly painful, swollen, warm, or produces discharge, or if fever develops, as these can be signs that need separate assessment. Also seek advice if the bandage will not stay in place on a wound that needs ongoing protection, or if a wound looks deep, is still bleeding, or was caused by a bite.
