Doctor suggested Calomine lotion and clotrmazole dusting powder 1% W/W. and motelukast,bilastine syrup for allergy. itching started by Monday evening. started medication yesterday evening. how long it takes to recover. no fever.if itching is heavy suggested to use atarax lotion. that too given once today.
