Hello, Welcome to Chat Doctor, As you are daughter has known allergic to dust, she should be very careful otherwise it may be dangerous to the life. I would suggest her to undergo absolute eosinophil count (AEC) which will be raised in the allergic condition. For the present symptoms you can give her Tab Monte LC which helps to control the symptoms, but it is temporary. She needs to avoid these dust allergens to protect herself from getting these allergy symptoms. I would suggest her to undergo skin prick test (SPT) to identify the type of dust causing these symptoms and can prevent herself from exposing to this dust. Otherwise, you can prefer immunotherapy either with subcutaneous immunotherapy (SUIT) or sublingual immunotherapy (SLIT). Thank you.
