Frequent nosebleeds are usually better in clinical practice with oral vitamin C pills and vitamin B complex tablets. Nosebleeds are most commonly caused by local causes in the nasal cavity, mainly due to dryness of the nasal mucosa, or bleeding caused by rupture of the arteries or venous plexus vessels in the nasal mucosa nasal septum Littoral area. Therefore, it is best to treat the nasal cavity topically while taking the above drugs orally. The nasal cavity can be treated with topical vitamin AD drops or Bevosol gel twice a day, and the usual course of topical application is one week. When the amount of nasal bleeding is small, treatment by medication is sufficient. If the amount of nasal bleeding is larger and more acute, usually oral medication and topical medication cannot relieve the bleeding, it is necessary to go to the hospital for laser treatment of the nasal mucosa. Usually after laser treatment, arterial or venous bleeding points in the nasal mucosa can be stopped.
