The nasal spray is a very common clinical drug, which has certain side effects: 1. Patients who apply it for a long time are likely to form dependence, and the symptoms of nasal congestion will be relieved after using the drug, and the symptoms of rhinitis will recur immediately after stopping the drug. 2. Some patients keep sneezing continuously after spraying the nasal spray, which means that the patient is not suitable for applying this medicine. Regardless of which of the above is the case, it is recommended that the patient promptly stop the medication and go to the hospital for further consultation and appropriate call for some rhinitis medication.
