Nosebleed (Epistaxis)

Epistaxis, or a nosebleed, is when you lose blood from the tissue that lines the inside of your nose. A combination of dry air and tiny blood vessels that line the inner surface of your nose often cause nosebleeds. There are simple steps you can take to treat and prevent them. Although annoying, nosebleeds usually aren’t a cause for concern.


What is epistaxis?

“Epistaxis” is the medical term for a nosebleed. A nosebleed, meaning a loss of blood from the tissue that lines the inside of your nose, can occur in one or both nostrils. Usually, it only affects one nostril.

Your nose has many tiny blood vessels in it. These vessels help warm and moisten the air you breathe. But they lie close to the inner surface of your nose. When air moves through your nose, it can dry and irritate your blood vessels. This makes them very easy to injure or break, causing a nosebleed.

Although bothersome, most nosebleeds aren’t serious.

How common is epistaxis?

Epistaxis is common. About 60% of people will have at least one nosebleed in their lifetime. Only about 10% of cases are severe enough to require medical treatment.

Who gets epistaxis?

Anyone can get epistaxis. Most people will have at least one case in their lifetime. However, some people are more likely to have a nosebleed. They include:

  • Children between the ages of two and 10: Dry air, colds, allergies and sticking fingers and objects into their noses make children more prone to nosebleeds.
  • Adults between the ages of 45 and 80: Blood may take longer to clot in mid-life and in older adults. These adults are also more likely to have high blood pressure, atherosclerosis (hardening of the walls of arteries) or a bleeding disorder.
  • Pregnant people: Blood vessels in your nose expand while you’re pregnant, which puts more pressure on the delicate blood vessels in the lining of your nose.
  • People taking blood-thinning medications: These drugs include aspirin and warfarin.
  • People who have blood clotting disorders: These include hemophilia and von Willebrand disease.

Types of nosebleeds

There are two main types of nosebleeds. Healthcare providers describe epistaxis by the site of the bleeding.

Anterior nosebleed

An anterior nosebleed starts in the front of your nose on the lower part of the wall that separates the two sides of your nose (septum). Capillaries and small blood vessels in this front area of your nose are fragile and can easily break and bleed. This is the most common type of epistaxis and usually isn’t serious. These nosebleeds are more common in children. You can usually treat these nosebleeds at home.

Posterior nosebleed

A posterior nosebleed occurs deep inside your nose. A bleed in larger blood vessels in the back part of your nose near your throat causes this type. It can result in heavy bleeding, which may flow down the back of your throat. You may need medical attention right away for this type of nosebleed. This type is more common in adults.

Symptoms and Causes

Nosebleeds have many causes, including dry air, allergies and recreational drug use.
A nosebleed, or epistaxis, is the loss of blood from the tissue that lines the inside of your nose.

What are the symptoms of a nosebleed?

Most often, you won’t have any symptoms other than blood coming from your nose. If you have a posterior nosebleed, some blood may drain down the back of your throat into your stomach. This can cause a bad taste in the back of your throat and make you feel nauseated.

If you have additional symptoms, it may be a sign of a medical condition.


What causes a nosebleed in one nostril?

Most nosebleeds only affect one nostril, but they can affect both at the same time. Epistaxis has many causes. Fortunately, most aren’t serious.

The most common cause of nosebleeds is dry air. Hot, low-humidity climates or heated indoor air cause dry air. Both environments cause your nasal membrane (the delicate tissue inside your nose) to dry out and become crusty or cracked. This makes it more likely to bleed when rubbed or picked or when blowing your nose. You may also experience epistaxis after inserting an object in your nose or injuring your nose and/or face.

Other nosebleed causes may include:

  • Infections: Colds (upper respiratory infections) and sinusitis, especially episodes that cause repeated sneezing, coughing and nose blowing.
  • Allergies: Allergic and nonallergic rhinitis (inflammation of your nasal lining).
  • Blood-thinning medications: Drugs such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), warfarin and others.
  • Recreational drugs: Cocaine and other drugs you inhale through your nose.
  • Chemical irritants: Chemicals in cleaning supplies, chemical fumes at workplaces and other strong odors.
  • High altitudes: The air is thinner (lack of oxygen) and drier as the altitude increases.
  • Deviated septum: An abnormal shape of the wall that separates the two sides of your nose.
  • Nasal sprays: Frequent use of nasal sprays and medications to treat an itchy, stuffy or runny nose. These medications — antihistamines and decongestants — can dry out your nasal membranes.

Other less common causes of nosebleeds include:

Diagnosis and Tests

What should I expect when I go to my provider about epistaxis?

A healthcare provider will ask you questions about your nosebleed, including:

  • Length (in minutes) of your nosebleed.
  • Approximate amount of blood that was lost.
  • How often you get them.
  • If the bleed involved one or both nostrils.

They’ll also ask about:

  • Medications you’re taking, including over-the-counter blood-thinning medications such as aspirin, and drugs for colds and allergies.
  • Your family history, including any history of blood disorders.
  • Your use of alcohol and/or any recreational drugs in which you sniffed the drug up your nose.

Next, your provider will examine your nose to determine the source of the bleeding and what may have caused it. They’ll use a small speculum to hold your nostril open and use various light sources or an endoscope (lighted scope) to see inside your nasal passages.

Your provider may use topical medications to numb (anesthetize) the lining of your nose and to narrow blood vessels. Your provider may remove clots and crusts from inside your nose. This can be unpleasant but isn’t painful.

Occasionally, they may order X-rays, a CT scan or blood tests to check for bleeding disorders, blood vessel abnormalities or nasal tumors.


Management and Treatment

How to stop a nosebleed

Use the following steps to stop a nosebleed at home.

  • Sit upright and lean your body and your head slightly forward. This will keep the blood from running down your throat, which can cause nausea, vomiting and diarrhea. (Don’t lay flat or put your head between your legs.)
  • Breathe through your mouth.
  • Use a tissue or damp washcloth to catch the blood.
  • Use your thumb and index finger to pinch together the soft part of your nose. Make sure to pinch the soft part of the nose against the hard bony ridge that forms the bridge of your nose. Squeezing at or above the bony part of your nose won’t put pressure where it can help stop the bleeding.
  • Keep pinching your nose continuously for at least five minutes before checking if the bleeding has stopped. If your nose is still bleeding, continue squeezing your nose for another 10 minutes.
  • If you’d like, apply an ice pack to the bridge of your nose to further help narrow blood vessels (which will slow the bleeding) and provide comfort. This isn’t a necessary step, but you can try it.
  • You can spray an over-the-counter decongestant spray, such as oxymetazoline (Afrin®, Dristan®, Neo-Synephrine® or Vicks Sinex®) into the bleeding side of your nose and then apply pressure to your nose. You shouldn’t use these topical decongestant sprays over a long period. Doing so can cause an increase in the chance of a nosebleed.
  • After the bleeding stops, don’t bend over, strain and/or lift anything heavy. Don’t blow or rub your nose for several days.

When should I see my healthcare provider about epistaxis?

Call your healthcare provider if:

  • You get epistaxis often.
  • You have symptoms of anemia (feeling weak, faint, tired, cold or short of breath or having pale skin).
  • You have a child under age 2 who has had a nosebleed.
  • You’re taking blood-thinning medications (such as aspirin or warfarin) or have a blood-clotting disorder and the bleeding won’t stop.
  • You get a nosebleed that seems to have occurred with the start of a new medication.
  • You get epistaxis, as well as notice unusual bruising all over your body. This combination may indicate a more serious condition such as a blood-clotting disorder (hemophilia or von Willebrand disease), leukemia or a nasal tumor.

What are the treatments for epistaxis?

Nosebleed treatment depends on the cause of the bleeding. Epistaxis treatment may include:

  • Nasal packing: Your healthcare provider will insert gauze, special nasal sponges or foam, or an inflatable latex balloon into your nose to create pressure at the site of the bleed. Your provider may want to leave the material in place for 24 to 48 hours before removing it.
  • Cauterization: This procedure involves applying a chemical substance (silver nitrate) or heat energy (electrocautery) to seal the bleeding blood vessel. Your provider will spray a local anesthetic in your nostril first to numb the inside of your nose.
  • Medication adjustments/new prescriptions: Reducing or stopping the amount of blood-thinning medications can be helpful. In addition, medications for controlling blood pressure may be necessary. Your provider may prescribe Tranexamic (Lystedaâ®), a medication to help blood clot.
  • Foreign body removal: If the cause of the nosebleed is a foreign object, your provider will remove it.
  • Surgery: Surgical repair of a broken nose or correction of a deviated septum (septoplasty) if this is the cause of the nosebleed.
  • Ligation: In this procedure, your provider will tie off the culprit blood vessel to stop the bleeding.


What can I do to prevent nosebleeds?

  • Use a saline nasal spray or saline nose drops two to three times a day in each nostril to keep your nasal passages moist. You can purchase these products over-the-counter or you can make them at home. To make the saline solution at home, mix 1 teaspoon of salt into 1 quart of tap water. Boil water for 20 minutes, and let cool until lukewarm.
  • Add a humidifier to your furnace or run a humidifier in your bedroom at night to add moisture to the air.
  • Spread water-soluble nasal gels or ointments in your nostrils with a cotton swab. Bacitracin®, Vaseline® or Ayr Gel® are examples of over-the-counter ointments you can use. Be sure not to insert the swab more than 1/4 inch into your nose. You can purchase these gels and ointments in most pharmacies.
  • Avoid blowing your nose too forcefully.
  • Sneeze through an open mouth. Always sneeze into a tissue or your elbow.
  • Avoid putting anything solid into your nose, including your fingers.
  • Limit your use of medications that can increase bleeding, such as aspirin and ibuprofen. Remember that any medication adjustment, especially prescribed medication such as warfarin (Coumadin®) and nonsteroidal anti-inflammatory drugs (NSAIDs), should only be done under your healthcare provider’s supervision.
  • See your provider if you can’t easily control your nasal allergy symptoms with over-the-counter or prescription medications. Make sure you closely follow the directions when using over-the-counter products. Overusing them can cause nosebleeds.
  • Quit smoking. Smoking dries out your nose and irritates it.
  • Wear protective headgear if involved in activities that could result in an injury to your face and nose.
  • Keep your child’s fingernails short.

If you have any questions or concerns, don’t hesitate to call your healthcare provider.

Outlook / Prognosis

When to worry about a nosebleed

Although seeing blood coming out of your nose can be alarming, most nosebleeds aren’t serious. You can usually manage them at home. However, you should have some cases of epistaxis checked by a healthcare provider. For instance, if you have frequent nosebleeds, see a provider. This could be an early sign of another medical issue that they’ll want to look into.

Some nosebleeds can start in the back of your nose. These cases of epistaxis usually involve large blood vessels resulting in heavy bleeding and can be dangerous. You’ll need medical attention for this type of bleed, especially if the bleeding occurs after an injury and the bleeding hasn’t stopped after 20 minutes of applying direct pressure to your nose.

Can you die from a nosebleed?

Nosebleeds that occur higher on your septum or deeper in your nose may be harder to control. However, nosebleeds are rarely fatal. They account for 4 out of every 2.4 million deaths in the United States.

Living With

Why do I get frequent nosebleeds in one nostril?

There are many non-serious reasons you may be getting frequent nosebleeds. They can affect one or both nostrils. The most common causes are:

  • Frequent use of nasal sprays for the treatment of allergy symptoms or colds/congestion. You may need to stop using these drugs for a short period or may need to stop them altogether. Talk with your provider if you use these products.
  • Living in dry air conditions.
  • Snorting drugs into your nose.

In rare cases, repeated epistaxis could be a sign of a bleeding disorder or other more serious conditions. If you have frequent nosebleeds, see a healthcare provider.

What causes nosebleeds while sleeping?

The reasons for nosebleeds during sleep are the same as the reasons why they occur during the daytime — dried nasal membranes caused by dry air, allergies and upper respiratory infections that damage the delicate nasal membrane lining your nose. Sleeping with your head to the side may also put direct pressure on your nasal cavity and may be another reason for epistaxis at night.

Can I drink water after a nosebleed?

Yes, you should drink plenty of fluids after a nosebleed. Good options include water, juice and other non-caffeinated liquids. After you experience epistaxis, some blood may drain down the back of your throat into your stomach. This may give you a bad taste in the back of your throat or make you feel nauseated. But drinking water won’t affect a nosebleed.

When should I go to the emergency room if I have a nosebleed?

Call your healthcare provider immediately, have someone drive you to the nearest emergency room or call 911 if:

  • You can’t stop the bleeding after more than 15 to 20 minutes of applying direct pressure on your nose as described in the steps above.
  • The bleeding is rapid or the blood loss is large (more than 1 cup).
  • You’re having difficulty breathing.
  • You’ve vomited because you’ve swallowed a large amount of blood.
  • Your nosebleed has followed a blow to your head or a serious injury (fall, car accident or a smash to your face or nose).

Additional Common Questions

Is it normal to have blood clots in a nosebleed?

Yes. Blood clots are clumps of blood that form in reaction to an injured blood vessel. Blood clotting prevents excessive bleeding when a blood vessel is damaged. When you pinch your nose to stop a nosebleed, the blood will begin to clot. It’ll normally remain there until you remove it or gently blow your nose.

Why do I have a headache and a nosebleed?

Many factors can lead to headaches and nosebleeds. A common cause of both symptoms is a deviated septum (a shifted wall in your nose). One study found that epistaxis may be a precursor to migraines. Other common causes of headaches and nosebleeds may include:

  • Allergies.
  • Weather changes.
  • Severe injuries.
  • Other medical conditions.
