Repeated episodes of skin rashes that last only for short time for few hrs and reappear again is very typical in urticaria. There are many allergens including certain food items , dust etc. that trigger rashes. Getting eosinophil count done helps to guide treatment duration and tests like ELISA are available to identify allergens. Treatment should be on long term basis to improve resistance in addition to avoiding the trigger rather than taking cetrizine on day to day basis. Take care.
