A nosebleed is bleeding from tissues inside the nose (nasal mucus membranes) caused by a broken blood vessel. The medical word for nosebleed is epistaxis. Most nosebleeds in children occur in the front part of the nose close to the nostrils. This part of the nose has many tiny blood vessels. These can be damaged easily. A nosebleed can look scary, but is usually not a serious problem. Nosebleeds are common in children. They happen more often in dry climates. They also happen more during the winter. That’s when dry heat in homes and buildings can cause drying, cracking, and crusting inside the nose. Many children outgrow nosebleeds during their teen years.

What are the symptoms of a nosebleed in a child?

The main symptom of a nosebleed is blood dripping or running from the nose. Bleeding from the mucus membranes in the front of the nose comes from only one nostril. Bleeding higher up in the nasal cavity may come from both nostrils. It may be painless. Or your child may have pain caused by an injury or an area of sore tissue inside the nose.

How is a nosebleed diagnosed in a child?

The healthcare provider will ask about your child’s symptoms and health history. He or she may also ask about any recent accidents or injuries. He or she will give your child a physical exam.

How is a nosebleed treated in a child?

• Calm and comfort your child.

• Have your child sit up and lean forward slightly. Don’t have your child lie down. This is to prevent him or her from swallowing blood. Swallowing blood may make your child vomit. Don’t have your child put his or her head between the knees. This can make bleeding worse.

• Tell your child to breathe out of his or her mouth. Gently pinch the nostrils closed for 5 to 10 minutes. Don’t stop pinching to check if bleeding has stopped.

• Apply a cold compress to the bridge of the nose. Don’t put tissues or gauze in your child’s nose.

• If bleeding does not stop, repeat the above steps again.

• Once the bleeding stops, tell your child not to rub, pick, or blow his or her nose for 2 to 3 days. This will let the broken blood vessel heal.

If your child’s nose doesn’t stop bleeding, take him or her to see the healthcare provider. In some cases a provider may apply heat to close a blood vessel. This is called cauterization. It is a quick procedure. Talk with your child’s healthcare providers about the risks, benefits, and possible side effects of all treatments.

How can I help prevent a nosebleed in my child?

If your child has nosebleeds often, you can help prevent them in these ways:

• Run a cool mist humidifier in your child’s room at night, if the air in your home is dry. Clean the humidifier regularly so germs and mold don’t grow in it.

• Teach your child not to pick his or her nose or blow it too hard.

• Put petroleum jelly inside your child’s nostrils several times a day. This is to help protect the mucus membranes.

• Use saltwater (saline) nose drops or spray as directed by your child’s healthcare provider.

• Talk with your child’s healthcare provider if your child has allergies that may lead to nosebleeds.

• Don’t smoke in the home or around your child.
