Adhesive reactions: irritation, allergy or just too tight?
Redness in the exact shape of the dressing is a reaction. Redness spreading beyond it is something else.
Skin reactions to dressings are common and usually manageable once you work out which of three things is happening.
Irritant contact dermatitis
The most common. Redness and itching exactly where the adhesive sat, appearing within a day. Usually caused by adhesive that is too aggressive for that skin, or by repeated removal from the same area.
Allergic contact dermatitis
Less common. A more intense reaction, sometimes with small blisters, and it may extend slightly beyond the adhesive. It develops with repeat exposure and tends to worsen each time.
Skin stripping
Not a reaction at all — shiny, raw patches where the top layer came away with the dressing. This is a technique and adhesive problem.
What to do
- Switch to a silicone adhesive, which is far gentler.
- Rotate the position slightly so the adhesive is not on the same skin each time.
- Remove low and slow, supporting the skin.
- See a pharmacist if the reaction is severe or persists after stopping.
Not a reaction: redness spreading outward from the wound itself, with heat and increasing pain. That is a possible infection.
See a pharmacist, GP or urgent care if a wound will not stop bleeding after ten minutes of firm pressure, is deep or gaping, was caused by something dirty or rusty, contains anything you cannot flush out, or shows spreading redness, heat, swelling, pus or a fever. Get help urgently for animal or human bites, wounds over a joint, and any wound in someone with diabetes or poor circulation.
