Hives are generally treated using antihistamines, cortisones, medications that fight inflammation and antibacterial agents such as Dapsone, according to the American Academy of Dermatology. Those who suffer from hives may need an injection of adrenaline, which is also known as epinephrine.
Treatment for hives requires first determining their cause. Avoiding exposure to irritants that are known to cause hives can help stave off future occurrences. Many cases of hives simply go away on their own and require no medications. Cases that last for a long time may require the use of over-the-counter antihistamines, according to WebMD, while cases that persist for a few days should be evaluated by a doctor.
People with chronic hives may need to take a daily antihistamine that keeps hives from forming, according to the American Academy of Dermatology. Dermatologists may order allergy tests, blood work or even skin biopsies to determine the cause of chronic hives. Allergy tests can take the form of skin or blood tests, and a skin biopsy involves removing a small piece of the hives-affected skin to examine it more closely with a microscope.
While hives are generally not serious, the condition can also indicate an internal disease, according to the American Academy of Dermatology. Those with recurrent hives should seek out evaluation by a medical professional.
