Up to half of the people who use medical plaster will develop an allergic reaction. Skin reactions to plaster can be categorized under allergic contact dermatitis.
Symptoms of Plaster Allergy
An allergic reaction to plaster may cause:
- Skin rash
- Itching
- Hives
- Burning sensation
- Weepy blisters
Rashes related to plaster allergy usually appear in the area of the skin that comes into direct contact with the bandage. The rash is typically red, raised, and itchy.
In severe cases, a plaster allergy rash can resemble a burn or a large, painful blister that can be highly prone to infection.
What Causes Plaster Allergy?
The chemical compounds found in bandage tape can cause allergic reactions in some people.
In particular, the sticky substance found in plaster is usually made from plastic chemicals known as propenoates or acrylates. These compounds are also found in products such as nicotine patches, artificial nails, wood polishes, and glossy paper among others.
Another major allergen responsible for an adverse reaction to plaster is rosin, also known as colophony.
Rosin is also found in the sticky part of the plaster. It is extracted from spruce or pine trees and is used in a wide array of applications for its adhesive qualities.
Rosin or colophony may also come in names such as abietic acid, abietyl alcohol, dertophene 18 or Gum rosin.
Another compound that can cause an allergic reaction is latex. However, many medical plasters no longer use this compound but you might want to check the label if you are using an old box of plasters.
How To Manage Plaster Allergy
If you notice an allergic reaction to a medical adhesive, you should stop usage immediately. The symptoms will usually disappear once you stop using the plaster.
Other alternatives to standard medical plasters include using paper tape or gauze to cover the wound. If you really must use plaster, opt for the hypoallergenic type.
