Nosebleed first aid
Informed by recognized medical guidance
Overview
A nosebleed (also called epistaxis) is bleeding from the inside of your nose. It can look scary but is usually not serious and often stops on its own with simple first aid.
Key facts
- Most nosebleeds stop on their own or with simple first aid like sitting forward and pinching the nose.
- Never tilt your head back during a nosebleed — it can cause blood to flow down your throat.
- Dry air, nose picking, and allergies are common triggers.
Yes, nosebleeds are very common. Most people will have at least one in their lifetime.
Anyone can get a nosebleed, but they are more common in children aged 2 to 10 and adults over 50.
Symptoms
- Bleeding that does not stop after 20 minutes of firm, continuous pressure
- You feel dizzy, lightheaded, or faint
- Heavy bleeding after a serious injury to the nose or head
- You are coughing up or vomiting large amounts of blood
- ⚠Frequent nosebleeds without a clear cause
- ⚠You take medications that thin the blood (like warfarin or aspirin)
- ⚠The bleeding stops but comes back quickly after you release pressure
Common symptoms
- Bleeding from one or both nostrils
- Blood dripping down the back of the throat
Symptoms in children
- Same as in adults, but children may be more frightened and need reassurance
Symptoms in older adults
- Older adults may have more frequent or longer-lasting nosebleeds due to thinner blood vessels or use of blood-thinning medications
Causes
Main causes
- Dry air (from heating or air conditioning) that dries out the inside of the nose
- Picking or rubbing the nose
- A minor injury to the nose
- Allergies, colds, or sinus infections that cause nasal irritation
- High blood pressure (though this is less common)
Risk factors
- Living in a dry climate or using indoor heating
- Taking blood-thinning medications or aspirin
- Using nasal sprays for allergies or colds
- Having a blood clotting disorder
- Being older, as blood vessels become more fragile
When to see a doctor
See a doctor urgently if:
- You have a nosebleed and also have difficulty breathing
- Bleeding does not stop after 20 minutes of applying pressure
- You lose a large amount of blood (more than a cup)
Book a routine appointment if:
- You get frequent nosebleeds (more than once a week)
- You have a nosebleed after a head injury, even if it stops
- You are taking blood-thinning medication and get a nosebleed that takes more than 10 minutes to stop
Diagnosis
A doctor will ask about your health and examine your nose with a light. They may check your blood pressure and ask about any medications you take.
Tests that may be done
- A blood pressure check
- Blood tests to check for clotting problems if nosebleeds are frequent or severe
- Sometimes a thin, flexible tube with a camera (nasal endoscopy) to look inside the nose
What to expect at your appointment
The doctor will look for the source of the bleeding, often a small blood vessel on the wall between the nostrils (the septum). The exam is usually quick and not painful.
Treatment
Treatment focuses on stopping the current bleed and preventing future ones. Most nosebleeds can be managed at home with simple first aid.
Self-care at home
- Sit forward and pinch the soft part of your nose (just below the bone) for 10 to 15 minutes
- Breathe through your mouth
- Place an ice pack wrapped in a cloth on the bridge of your nose
- Do not tilt your head back — this can make blood flow into your throat
Medical treatments
If first aid does not work, a doctor may place a special packing inside your nose to stop the bleeding. They may also use a chemical or electrical tool to seal off the bleeding blood vessel (cautery). These procedures are safe and effective.
When is surgery considered?
In rare cases, if bleeding cannot be controlled with packing or cautery, a minor surgical procedure to tie off or block the bleeding vessel may be needed. This is very uncommon.
Living with this condition
If you have frequent nosebleeds, keep the inside of your nose moist. Use a saline (salt water) spray or a light layer of petroleum jelly inside each nostril, especially in dry weather.
Lifestyle tips
- Avoid picking your nose
- Avoid heavy lifting or straining during bowel movements
- Use a humidifier in your bedroom to add moisture to the air
- Try not to blow your nose forcefully for 24 hours after a nosebleed
Diet and exercise
Stay well hydrated by drinking enough water. There are no specific restrictions on exercise, but avoid activities that might cause injury to the nose for a day or two after a bleed.
Mental health and emotional wellbeing
Frequent nosebleeds can be worrisome or embarrassing. If you feel anxious about nosebleeds, talk to your doctor. They can help find the cause and offer treatments to reduce their frequency.
Prevention
You can reduce your risk of nosebleeds by keeping the inside of your nose moist, not picking your nose, and using a humidifier in dry environments.
Vaccines
Not applicable
Screening programmes
Not routine; if you have frequent nosebleeds, your doctor may check your blood pressure and do simple blood tests to look for underlying causes.
Complications
If left untreated
- Rarely, heavy bleeding can lead to significant blood loss and anemia (low red blood cells)
- Blood can be inhaled into the lungs, though this is very uncommon
- Frequent nosebleeds can be uncomfortable and may interfere with daily life
Long-term outlook
The outlook is excellent. Almost all nosebleeds stop with simple first aid. For those that do not, medical treatment is highly effective. With proper care, most people have no long-term problems.
