Nosebleeds are not usually a sign of anything serious. They're common, particularly in children, and most can be easily treated at home.

Non-urgent advice: See a GP if:

  • a child under 2 years old has had a nosebleed
  • you have regular nosebleeds
  • you have symptoms of anaemia – such as a faster heartbeat (palpitations), shortness of breath and skin that is paler than normal for you
  • you have a nosebleed and you're taking a medicine that helps prevent blood clots, such as warfarin
  • you have a nosebleed and you have a condition that means your blood cannot clot properly, such as haemophilia

The GP might want to test you for haemophilia or for other conditions like anaemia.

Immediate action required: Go to A&E if:

You have a nosebleed and:

  • your nosebleed lasts longer than 10 to 15 minutes
  • the bleeding seems excessive
  • you're swallowing a large amount of blood that makes you vomit
  • the bleeding started after a blow to your head
  • you're feeling weak or dizzy
  • you're having difficulty breathing

If this is not possible, they might pack your nose with ribbon gauze or sponge, to stop the bleeding. You may need to stay in hospital for a day or two.

When your nosebleed stops, a doctor may prescribe an antiseptic cream to use inside your nose. This stops crusting, or scabs forming. Check the cream's ingredients first, as it may not be suitable if you have a peanut or soya allergy.
