   Treatment of cold urticaria involves avoiding the cold, when possible, and taking antihistamines. The antihistamines are best taken before exposure to cold temperatures to block some of the histamine release. Many of the over-the-counter antihistamines interfere with learning. I recommend a nonsedating drug, such as loratadine (Claritin) or cetirizine (Zyrtec).
   Sometimes cold urticaria is a symptom of another problem, such as cryofibrinogenemia, cryoglobulinemia, or syphilis. Even when it is not, you can develop cold urticaria after receiving a blood transfusion from someone who has it. Most people don't know that allergies can be transmitted in transfusions, but they can (Nelson Textbook of Pediatrics, WB Saunders, 2000)! For some people, cold urticaria is a lifelong condition; for others, it is temporary -- only during and after an infection, such as mycoplasma or mononucleosis.
   Both mononucleosis and mycoplasma infections can produce another type of cold allergy in the blood. Following these and a variety of other viral infections, exposure to the cold can cause anemia from allergic bursting of some of the red blood cells.
