If the nose is too dry and bleeds easily, consider using medications that lubricate the nasal mucosa, such as compound menthol nasal drops to drip the nose 1-2 drops/time, 3 times/day. You can also apply Befixin to the inside of the nasal cavity, especially the mucous membrane of the nasal septum, 3 times/day. You can also rinse the nasal cavity with physiological sea saline 1-2 times/day, or you can go to a medical equipment store and buy a nasal rinse and some saline for nasal rinsing. In the case of children, sometimes there is a dryness and bleeding of the mucous membrane of the nasal cavity due to frequent picky eating, which causes nutritional imbalance. Therefore, it is also necessary to pay attention to the nutritional balance of the child. If necessary, oral vitamins can be taken. Both adults and children must not pick their noses or rub their noses during the medication period, otherwise the mucosal bleeding symptoms will not recover easily.
