The first-line treatment for an ordinary nosebleed is sustained pressure on the soft part of the nose while sitting upright and leaning forward. The nose should be pinched just above the nostrils, where the soft tissue can be compressed against the septum, for 10 to 15 minutes without repeatedly releasing the pressure to check whether bleeding has stopped. The person should breathe through the mouth. Leaning forward is important because it allows blood to leave through the nose rather than flowing backwards into the throat, where it may be swallowed and potentially cause nausea or vomiting. This simple compression technique stops most uncomplicated anterior nosebleeds.
Sitting upright and leaning forward also helps maintain a safe airway and makes it easier to assess ongoing bleeding. Lying flat or tilting the head backwards is generally discouraged because blood can run down the throat and be swallowed or aspirated. The traditional instruction to "tilt your head back" is therefore counterproductive for routine first aid. The key mechanical principle is direct compression of the bleeding vessels for long enough to allow stable clot formation. Releasing pressure after only a minute or two is a common reason for apparent treatment failure because the developing clot can be disrupted before it has stabilised.
A cold pack placed over the bridge or upper part of the nose may sometimes be used as an additional measure, although the NHS notes that evidence for its effectiveness is not strong. It should never replace correct compression. Ice should not be applied directly to skin because prolonged direct exposure can cause cold injury. Similarly, inserting tissues, cotton wool or other material deeply into the nose is not a substitute for compression and can disturb the clot when removed. The essential treatment remains sustained pressure applied correctly to the soft nose.
Once the nosebleed has stopped, the recently injured vessel needs time to stabilise. For about 24 hours, the NHS advises avoiding nose blowing, nose picking, hot drinks, alcohol, heavy lifting, strenuous exercise and picking at scabs. These activities can increase nasal blood flow or mechanically disrupt the developing clot. Keeping the nasal lining protected from further trauma reduces the chance of immediate rebleeding. A person who experiences repeated bleeding should not simply continue treating every episode indefinitely at home without investigating why the episodes are occurring.
If a doctor can identify the bleeding point, treatment may involve cautery, in which a chemical or other method is used to seal the responsible vessel. If bleeding cannot be controlled this way or is coming from a deeper location, nasal packing may be used. Packing physically compresses the nasal tissues and vessels to control haemorrhage and may require hospital observation. The appropriate intervention depends on the source and severity of bleeding, whether the bleeding can be visualised and controlled, and whether the person has risk factors such as anticoagulant treatment or a bleeding disorder.
Medical assessment is appropriate for recurrent nosebleeds, a nosebleed in a child under two, bleeding in someone taking anticoagulants, or bleeding in someone known to have a disorder affecting coagulation. Clinicians may investigate for anaemia, coagulation abnormalities or local nasal causes when episodes are frequent. Persistent dryness or crusting may sometimes be managed with an appropriate nasal treatment recommended by a clinician or pharmacist. The purpose is not merely to stop each episode but to reduce recurrence and identify any underlying contributor.
Emergency care is required when the nosebleed lasts longer than 10 to 15 minutes despite correct compression, the bleeding appears excessive, a large amount of blood is being swallowed and causes vomiting, the person becomes weak or dizzy, breathing becomes difficult, or the bleeding began after a significant blow to the head. Such features can indicate substantial blood loss, a posterior bleed or significant trauma. In an emergency, 999 should be called rather than attempting to drive an unstable person to hospital.
Nosebleed treatment should not include attempts to straighten a potentially broken nose, forcefully blow out clots, repeatedly probe the nasal cavity or insert objects into the nose. A broken nose should be assessed separately when deformity, significant swelling, persistent obstruction or other concerning features are present. Most simple nosebleeds are successfully treated with correct compression, but treatment failure should prompt reassessment of the diagnosis or bleeding source rather than increasingly aggressive home manipulation. The distinction between simple anterior epistaxis and significant or posterior bleeding is central to safe management.
