Patients with allergic rhinitis usually do not need to be given an IV unless the symptoms are very serious, such as high edema of the nasal cavity and complete lack of ventilation, and the eyes may also have certain allergic symptoms, including conjunctival congestion and constant tearing, which prevent them from sleeping at night and from working and studying during the day. The main purpose of the drip is to administer hormonal drugs intravenously, commonly used is methylprednisolone injection, which can quickly play an anti-inflammatory and swelling effect, so that nasal ventilation can be improved to reduce the symptoms of discomfort. If there is a significant improvement can be considered oral hormone drugs to continue consolidation treatment for three days, the common clinical use is methylprednisolone tablets, the specific dose of drugs need to be applied under the guidance of a doctor.
