Nosebleeds: First aid

When to seek emergency help

Seek emergency help if:

  • Nosebleeds involve a greater than expected amount of blood.
  • Nosebleeds last longer than 30 minutes.
  • You feel faint or lightheaded.
  • The nosebleed follows a fall or an accident. Bleeding after a fall or an injury to the head or face could mean that you have broken the nose.
