Skin rash with wheals for allergies

A skin rash with wheals (urticaria) can be caused by an allergic reaction. This is a so-called type I allergy. After contact with the allergen, substances such as histamine and other inflammatory mediators are released in the body, which lead to the typical symptoms of the allergic reaction.

These include not only skin rashes and itching, but also shortness of breath, circulatory problems, nausea and oedema. In the case of an allergic skin rash with wheals, antihistamines are used therapeutically to stop the itching.In addition, tablets containing corticosteroids, such as dexamethasone or prednisolone, are administered. If accompanying circulatory reactions, shortness of breath or even oedema of the eyelids, lips or tongue occur, immediate therapy is initiated via the vein.
