What Causes Nosebleeds in Children and How Should Parents Manage Them?

Primary Causes Parents Should Know

The most common cause of nosebleeds in children is digital trauma (nose picking), which damages the fragile blood vessels in the front part of the nose. 1 Three out of four children will experience at least one nosebleed, with the average age being 7.5 to 8.5 years. 2, 3

Key causes to explain to parents:

• Nose picking is the leading culprit, causing direct injury to delicate blood vessels in the anterior nasal septum 1, 4
• Dry nasal passages, especially during winter months with indoor heating or in dry climates, make vessels more prone to bleeding 1, 4
• Upper respiratory infections, allergies, or nasal inflammation increase mucosal fragility and bleeding risk 1
• Minor facial trauma from play or sports can trigger bleeding 4

Immediate Management Instructions for Parents

Tell parents to apply firm, sustained compression to the soft lower third of the nose for at least 5 continuous minutes without checking if bleeding has stopped. 1 This is the single most important first-line treatment. 5

Step-by-step instructions:

• Have the child sit upright with head tilted slightly forward (never backward, as this causes blood to flow down the throat and obscures bleeding severity) 5, 1
• Pinch the soft part of the nose firmly for a full 5 minutes by the clock without releasing 1, 6
• If bleeding continues after 5 minutes, maintain compression for a full 15 minutes continuously 1
• Over-the-counter nasal decongestant spray (oxymetazoline/Afrin or phenylephrine) can be applied before compression, which stops bleeding in 65-75% of cases 2, 1

Common pitfalls to warn parents about:

• Do NOT repeatedly check if bleeding has stopped during compression—this prevents clot formation 7
• Do NOT tilt the head backward—this increases aspiration risk 7
• Do NOT insert tissues or cotton into the nostrils—they can be aspirated and removal disrupts clot formation 1, 7

Prevention Strategies

Parents should implement daily nasal moisturization to prevent recurrence, which resolves up to 65% of cases. 8, 6

Specific preventive measures:

• Apply nasal saline gel or spray regularly, especially before bedtime 1, 6
• Use a bedroom humidifier during winter months or in dry climates to maintain adequate indoor humidity 1, 6
• Keep fingernails trimmed short and gently discourage nose picking through positive reinforcement 1
• Teach proper gentle nose blowing during colds rather than forceful blowing 1
• Continue moisturization even after bleeding resolves to prevent recurrence 1

When to Seek Medical Attention

Tell parents to contact a healthcare provider if:

• Nosebleeds occur more than once weekly despite preventive measures 1
• Any single episode lasts longer than 20 minutes despite proper compression 1
• There is unilateral foul-smelling nasal discharge (suggests foreign body) 1
• The child shows signs of significant blood loss (pallor, dizziness, weakness) 5
• There is a family history of bleeding disorders or the child bruises easily 2

What to Expect if Medical Treatment is Needed

If home measures fail, medical providers may use:

• Silver nitrate cautery to the bleeding site (75% concentration is more effective and less painful than 95%) 9
• Topical vasoconstrictors applied directly to the bleeding site 2
• Nasal packing with resorbable materials in rare cases 1

Most pediatric epistaxis cases (93.5%) require only simple anterior treatment when medical intervention is needed, with only 6.9% of children presenting to emergency departments requiring any procedure. 2

Reassurance Points for Parents

• Nosebleeds in children are extremely common and usually benign 2, 8
• The amount of blood often appears more dramatic than the actual volume lost 6
• With proper first aid and prevention, most cases resolve completely 1, 6
• Only 0.16% of all epistaxis cases require hospitalization 2
