When this fails, and urticaria is felt to be due to a food or medication allergy, it is necessary for patients to keep a detailed minute by minute record of all foods and medications along with comments regarding the status of the condition in an attempt to determine the cause. When neither laboratory data, history or the diary of materials taken as medications or as food has not been helpful in finding the cause of chronic urticaria, evaluation by an Allergist is necessary. Any suspected old drugs should be eliminated for several months. It may even be necessary to discontinue all medications. Some measure of immediate relief may be obtained by cool baths and the application of a soothing lotion.
Antihistamines are often helpful.
In some patients, several of these may need to be tried in succession, or two of these may need to be used simultaneously before the best effect is obtained. Although corticosteroids may, on occasion be used in severe, acute attacks they are not advisable for most instances of chronic urticaria. Anytime severe itching persists, a product that is formulated in a soothing, emollient base is Sarna Lotion. Sarna Lotion is an excellent anti- itch lotion that will provide immdediate relief of itchy skin. In those conditions that are characterized by chronic and recurrent itchy skin, Sarna Lotion provides the relief to calm the irritating and antagonizing symptom of itch.
