What is nosebleed (epistaxis)?

Having a nosebleed (epistaxis) is common and is usually mild.

More severe cases can occur for people who:

  • are elderly
  • are being treated with blood thinning medication
  • have a known blood disorder.

What causes a nosebleed?

There is a delicate network of blood vessels just inside the nose. This area can spontaneously bleed, or some of the following can cause it to bleed:

  • Picking the nose
  • Colds and blocked stuffy noses, such as with hay fever
  • Blowing the nose
  • Minor injuries to the nose
  • Cocaine use
  • Blood clotting disorders
  • Blood thinning medications (e.g. rivaroxaban, apixaban, aspirin, warfarin)

Some people with high blood pressure (hypertension) or heart failure have a higher risk of having a nosebleed that lasts longer.

Bleeding sometimes comes from other areas further back in the nose. Such bleeds are sometimes due to uncommon disorders of the nose, or to serious injuries to the nose. Bleeding due to these causes, always need to be dealt with in the emergency and or by an ear nose and throat (ENT) specialist.


For most nosebleeds, simple first aid can usually stop the bleeding such as:

  • sitting up and leaning forward
  • blowing your nose, followed by pinching the fleshy end of your nose (closing both nostrils) and applying strong pressure (it should not hurt) for 10-20 minutes
  • if available, using a cold flannel or compress around the nose and front of face can help by closing (constricting) the blood vessels.

If the bleeding stops, avoid blowing or picking of your nose as you may dislodge a clot and the bleeding may recur

In the emergency department some of the following measures may be applied

  • The nose will be sprayed with substances that help to close (constrict) the blood vessels.
  • The nose may be packed for a few hours with watery compresses that are inserted and expand in your nose to apply pressure from the inside out.
  • Sometimes it is possible to see exactly where the nose is bleeding from and to 'burn' (cauterise) the bleeding point. This is a minor, painless procedure which is usually successful in stopping bleeds.

What to expect

Return to the emergency department if you experience any of the following:

  • Heavy bleeding or bleeding that does not stop within 20-30 minutes
  • You are feeling dizzy or lightheaded
  • You feel breathless or have chest pain

Seeking help

In a medical emergency call an ambulance – dial triple zero (000). If you have any concerns, see your local doctor or healthcare professional. If this is not possible return to the emergency department or urgent care centre.
