A hives fever is manifested by itchy wheals, as in contact with stinging nettles. The reddened skin swellings migrate within minutes to hours to different parts of the body. The itching is usually intensified by scratching.
A distinction is made between acute urticaria (<6 weeks) and chronic urticaria (>6 weeks) according to the duration of the urticaria.
Acute urticaria is often triggered by an infection but can also occur as a symptom of allergy. This usually lasts a few hours to days and usually does not require clarification. The trigger of chronic urticaria is often difficult to determine, allergies are rarely the cause. Mechanical (pressure, scratching) or physical stimuli (heat, cold) often play a role. Urticaria can also be further exacerbated by physical or psychological stress. In the case of chronic urticaria, it makes sense to consult a specialist. Often, however, no cause is found.
Therapy of urticaria
Antihistamines are the basis of the therapy. Some of these must be taken in high doses for weeks to months. In the case of severe forms of urticaria which respond insufficiently to antihistamines, therapy with the IgE antibody Omalizumab (Xolair) may be considered.
The form of therapy and dosage must be determined individually with each patient and adapted if necessary. The Dermanence dermatology team is there for you. Together we will select the optimal therapy for you.
