The trigger is often obvious and the condition disappears, or is easily treated. Antihistamines make the hives less itchy, though they may not make them disappear any faster. Many antihistamines, such as Benadryl and Chlor-Trimeton are easily obtained without a prescription. The newer, less-sedating medications require a prescription. Dosage is adjusted until symptoms are controlled, then the antihistamine is gradually tapered and discontinued.
Hives can be an uncomfortable and annoying problem.
Fortunately most cases clear up with simple management. However, a case of chronic hives should be evaluated. It could indicate a significant underlying medical condition.
