They work by blocking the action of histamine, a chemical that is released by the body in response to an allergic reaction. Antihistamines can reduce itching, swelling, and redness associated with hives. Over-the-counter antihistamines such as diphenhydramine (Benadryl) and loratadine (Claritin) can be taken as needed for mild symptoms. However, for severe reactions, a prescription-strength antihistamine may be necessary.

Some foods and medications can exacerbate the symptoms of cold urticaria. These include aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, and certain antibiotics. Additionally, some foods such as shellfish, nuts, and dairy products can trigger an allergic reaction and symptoms in people with cold urticaria. Avoiding these triggers can help reduce the severity and frequency of symptoms.
