Nosebleed first aid is simple, but it is often done wrongly. Most nosebleeds come from small, fragile vessels at the front of the nose and stop within ten to fifteen minutes with the right technique. The right technique is not tilting the head back. This guide shows the correct method, how to avoid a repeat bleed and which nosebleeds need medical help.
Nosebleed First Aid: 5 Steps
- Sit upright and lean forward. This keeps blood out of the throat and stomach. Do not tip the head back.
- Pinch the soft part of the nose. Squeeze firmly just below the bony bridge, closing both nostrils, and breathe through the mouth.
- Hold for ten minutes without letting go. Use a clock. Releasing early to check restarts the bleeding.
- Spit out any blood collecting in the mouth, and apply a cold pack to the bridge of the nose or the back of the neck if you wish.
- Repeat once. If it is still bleeding, pinch for a further ten minutes. If it continues, seek medical help.
After Nosebleed First Aid: Preventing a Repeat Bleed
Avoid blowing, picking or rubbing the nose for several hours, avoid hot drinks and strenuous exercise, and keep the head higher than the heart when resting. A little petroleum jelly just inside the nostril can protect dry membranes.
When a Nosebleed Needs Medical Help
- Bleeding continues after twenty minutes of correct pressure, or restarts when pressure is released
- It follows a blow to the head or face, or a suspected skull or nose fracture, particularly with clear fluid from the nose
- Heavy bleeding with dizziness, paleness or fainting
- The person takes blood-thinning medication, or has a bleeding disorder or very high blood pressure
- Repeated nosebleeds
After a head injury, follow our guidance on head injuries rather than simply pinching the nose.
Common Causes and Prevention
Dry air, colds, allergies, nose picking, forceful blowing and minor knocks are frequent causes. Humidifying indoor air, treating dry nostrils with an approved saline spray or ointment and trimming children’s fingernails can reduce repeat nosebleeds.
Nosebleed in an Unconscious Person
Place them in the recovery position so blood drains from the nose and mouth, and call an ambulance.
Why Leaning Forward Matters in Nosebleed First Aid
Many people grew up being told to tilt the head back during a nosebleed. This sends blood down the back of the throat, where it can be swallowed, causing nausea and vomiting, or inhaled, which is dangerous for children and people with swallowing difficulties. Leaning forward keeps the airway clear and lets you see how much blood is being lost. The firm pinch applies pressure to the area at the front of the septum where most nosebleeds begin, so the position of the fingers matters more than the position of the head.
Nosebleeds in Children, Older Adults and Pregnancy
Children are prone to nosebleeds because their nasal lining is delicate and they often pick or rub their noses. Reassure them, sit them on your lap leaning forward and use the same ten-minute pinch while distracting them with a story or book. Older adults and people taking aspirin, clopidogrel, warfarin or newer blood thinners can bleed for longer, so allow extra time and seek medical advice if bleeding is heavy. Pregnancy increases blood flow to the nasal lining, making nosebleeds more common, and the same first aid applies.
Nosebleed First Aid: What Not to Do
- Do not pack tissue or cotton wool deep into the nostril.
- Do not lie flat or tilt the head back.
- Do not release pressure early to look.
- Do not blow the nose afterwards for several hours.
Frequently Asked Questions
Should I tilt my head back during a nosebleed?
No. Leaning forward prevents blood running down the throat, which can cause choking or vomiting.
Is a nosebleed in a child serious?
Usually not, and the same technique applies. Seek help if bleeding is prolonged, frequent or follows an injury.
