There are a number of people who experience allergic skin reactions as a result of using adhesive bandages. After wearing an adhesive bandage for a day or two, an itchy red rash appears in the shape of the adhesive bandage on the skin. These reactions are caused by contact dermatitis to the adhesive, latex, or even medication (such as a topical antibiotic cream) placed under the bandage. In addition, as the delivery of topical medications -- such as nicotine patches and birth control patches -- becomes more common, so do the reactions to the transdermal patches. Again, these reactions can be caused by the adhesive, latex, or even the medication itself. Learn more about the causes of adhesive allergy, including the diagnosis and treatment of this increasingly common problem.
