But when hives are accompanied by other, more frightening symptoms, such as tightness in the throat, wheezing, and shortness of breath, the allergic reaction is an emergency and requires prompt medical attention. The best treatment for all allergic reactions, of course, is prevention. You have a severe case of hives that does not respond to Home Care. Apply calamine lotion to soothe itching. If you're severely allergic to certain substances, ask your doctor if you should carry an allergy kit that contains injectable epinephrine to head off severe and potentially life-threatening reactions that usually begin with hives and shortness of breath.
Cold compresses can help relieve itching.
If you are eating when an outbreak of hives occurs, stop. Chances are, it's some substance in the food that's causing the reaction. Stay away from the substances that you've had an allergic reaction to in the past. Insect venom, shellfish, nuts, certain berries, eggs, milk, antibiotics, and aspirin are common offenders.
