When spraying medicine into the nasal cavity, the medicine mist will be distributed to the nasal septum, and it doesn't matter if it is sprayed. Just don't deliberately spray the nozzle on a place of the nasal septum for a long time, which may cause mucosal erosion and bleeding of the nasal septum, and in rare cases, perforation of the nasal septum may occur.
