Nosebleeds in patients with colds are mainly caused by rupture of the nasal mucosa. Cold is the most common type of acute upper respiratory tract infection that can cause an acute inflammatory response in the upper respiratory tract, including the nasal cavity, so patients with cold often have symptoms of runny nose because it can lead to congestion and edema in the nasal cavity, so if the congestion and edema are strong, it can lead to rupture of the nasal mucosa and bleeding, causing the symptoms of nosebleed, but most of the symptoms of this kind of nosebleed are relatively mild. The bleeding can be stopped by caulking or can be relieved by antihistamines, such as cetirizine hydrochloride or loratadine. If accompanied by fever and cough, you can choose a combination of cold medications to relieve the symptoms, including meprobamate solution, compound aminoglutethimide, etc.
