Paint has a great impact on people’s health, mainly because paint can stimulate the patient’s nasal mucosa and cause allergic rhinitis, the main smell is formaldehyde benzene and other pollutants emitted, among which formaldehyde is the strongest stimulus for the respiratory tract. It is recommended that patients must avoid prolonged contact with paint, especially if the house has just been renovated, and must be fully ventilated before moving in. For the case of allergic rhinitis, you can spray with mometasone furoate nasal spray, nasal spray of azelaic acid, and if necessary, you need to add oral anti-allergy drugs.
