Nosebleed usually can stop bleeding after compression, no medication is needed; if the bleeding does not stop, drugs such as phenol sulfonyl ethylamine can be chosen to stop bleeding, if there is a combination of hemophilia, vitamin K-dependent coagulation factor deficiency and so on, oral vitamin K can be chosen to carry on the treatment. Generally speaking, nosebleeds can be stopped by the activation of their own coagulation mechanism, and there is no need to take oral medication. If the amount of bleeding is large, or repeated bleeding occurs, it may be due to the thicker blood vessels or the existence of ulcers in the nasal mucosa, etc., and the bleeding can be stopped by oral phenol sulfonyl ethylamine and other hemostatic drugs. However, it should be noted that allergy is prohibited. For those with abnormal coagulation function, along with the above hemostatic drugs, vitamin K1 and other drugs can be taken orally to treat vitamin K-dependent coagulation factor deficiency. The treatment of hemophilia is usually intravenous infusion of clotting factors, and oral medication is less common. It is recommended to go to the hospital if you have more than one nosebleed.
