If the patient’s eyes, nose and throat are itchy, it is mainly due to allergies, probably because the patient’s nose is the first to have allergy symptoms, and if not treated in time, it will affect the patient’s eyes and throat. Patients can take ketotifen tablets or montelukast sodium tablets orally and use sodium cromoglycate eye drops inside the eyes, which can effectively play an anti-allergic role. The patient’s nose can be sprayed with mometasone furoate nasal spray or nasal spray of azelastine hydrochloride, and the throat can be treated with tablets, such as fatty sea tablets or silver yellow tablets.
