Most nosebleeds are minor and can be stopped if you apply
direct pressure by pinching your nostrils shut for 10 minutes. See how to stop a nosebleed. Bleeding in the back of the nose (posterior
epistaxis) may cause a heavy nosebleed that continues after 10 to 20 minutes of
home treatment. This type of nosebleed is less common and usually requires
medical treatment to stop the bleeding.
Moderate to large amounts of blood flowing
continuously from the nose or down the throat despite 10 minutes of direct,
continuous pressure to the nose
Bleeding that continues despite 20
minutes of direct, continuous pressure (2 times for 10 minutes each)
If severe bleeding occurs with signs of
shock, call911or other emergency services immediately.
