Most nosebleeds are mild and do not last long. Nosebleeds also known as epistaxis are common in children and older people with medical conditions but can also occur after an injury or cold.
If a nose bleed is very heavy and does not stop after 15 minutes of non-stop pressure, you need to go to your nearest emergency department. It may be necessary for a doctor or nurse to pack your nose with dressings to stop the bleeding.
While most nosebleeds settle easily with simple first aid measures, some can be serious. Severe nosebleeds, especially those coming from the area at the back of the nose, may require nasal packing with gauze or a special type of inflatable latex balloon. Alternatively, nasal cautery (where the bleeding vessel in the nose is sealed by applying a special solution or an electrical or heating device) may be performed. You must consult your doctor if you have continuous nose bleeding which is a sign of an underlying medical emergency.
