A nosebleed is loss of blood from the tissue lining the nose. Bleeding most often occurs in 1 nostril only.

Alternative Names

Bleeding from the nose; Epistaxis


Nosebleeds are very common. Most nosebleeds occur because of minor irritations or colds.

The nose contains many small blood vessels that bleed easily. Air moving through the nose can dry and irritate the membranes lining the inside of the nose. Crusts can form that bleed when irritated. Nosebleeds occur more often in the winter, when cold viruses are common and indoor air tends to be drier.

Most nosebleeds occur on the front of the nasal septum. This is the piece of the tissue that separates the 2 sides of the nose. This type of nosebleed can be easy for a trained professional to stop. Less commonly, nosebleeds may occur higher on the septum or deeper in the nose. Such nosebleeds may be harder to control. However, nosebleeds are rarely life threatening.

Repeated nosebleeds may be a symptom of another disease such as high blood pressure, a bleeding disorder, or a tumor of the nose or sinuses. Blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, may cause or worsen nosebleeds.

Home Care

To stop a nosebleed:

It may help to apply cold compresses or ice across the bridge of the nose. Do not pack the inside of the nose with gauze.

Lying down with a nosebleed is not recommended. You should avoid sniffing or blowing your nose for several hours after a nosebleed. If bleeding persists, a nasal spray decongestant (Afrin, Neo-Synephrine) can sometimes be used to close off small vessels and control bleeding.
