Urticaria or hives are often associated with itching. Corticosteroid drugs like prednisone when offered may not provide additional relief to emergency patients who suffer from hives than a placebo did, finds a randomized, placebo-controlled, double blind, parallel-group study that is published in the Annals of Emergency Medicine.
"Prednisone is a strong and great drug for certain problems, but it is no better than antihistamine treatment for patients who are itching with hives," said lead study author Caroline Barniol, MD, of the Centre Hospitalier Universitaire in Toulouse, France.
"The antihistamine levocetirizine alone achieved full itching relief within 2 days for 76 percent of patients. With the addition of prednisone, the relief scores were actually worse."
Acute urticaria, or hives, is a fairly common presentation in the emergency department. Itching is frequently associated with hives and can interfere with daily activities and sleep. International guidelines published in 2013 stated that a short course of oral corticosteroids may be helpful to reduce disease duration for acute hives. Prednisone is commonly prescribed in the emergency department to treat them, along with antihistamines.
"Despite the evidence that second-generation H1-antihistamines treat acute urticaria without disturbing side effects, many physicians believe that corticosteroids are still the most effective treatment to obtain rapid symptom relief," said Dr. Barniol. "Our results do not support the addition of corticosteroid to antihistamines as a first-line treatment of uncomplicated acute hives. Even if short-term treatment with corticosteroids does not cause clinically significant toxicity, recurrent or long-term treatment may have deleterious effects."
