Nasal spray hormone generally only acts on local nasal cavity and is rarely absorbed throughout the body, which is relatively safe. The correct use of nasal spray hormone is as follows: nasal spray: spray the right nostril with the left hand, spray the left nostril with the right hand, and avoid directly spraying to the nasal septum (cartilage in the middle of the nose). Adults: 2 sprays for each nostril at the beginning, once in the morning and once in the evening. The maximum daily dosage shall not exceed 8 sprays. After symptom relief, spray one time per nostril every day. The usage and dosage for children over 6 years old are the same as those for adults. Clean the nasal cavity with paper towel or flush the nasal cavity with sea salt water before medication; Take out the bottle, put your thumb under the bottom of the bottle, fix the bottle with your index finger and middle finger, and shake the bottle at the same time; After the protective cover is opened, the thin head of the medicine is inserted into the nostril for spraying; Spray the other side of the nose with the other hand; After use, put on the bottle cap. For patients with general allergic rhinitis, it is recommended to use it for 3 months. If it needs more than 3 months, it is recommended to go to the otolaryngology head and neck surgery department for consultation and use it under the guidance of doctors according to the situation of nasal cavity. Nasal spray hormone can also be used indiscriminately without hunger. For example, some patients with nasal fungal infection (try not to use nasal spray hormone because nasal spray hormone has no effect on fungi) may get worse if they do not go to the hospital for treatment.
