The skin inside your nose is fragile and filled with blood vessels. That's why even a slight injury to your nose sometimes may cause bleeding. Hard nose blowing, dry winter air, colds, and nose-picking can also cause nosebleeds. Some medicines, such as warfarin, aspirin, and other blood thinners, can make it more likely to have a nosebleed that is difficult to stop. Normally, nosebleeds are not a cause for concern. But in some cases, they can signal a more serious health problem. Know when to seek medical care for a nosebleed.

When to go to the emergency room (ER)

Most nosebleeds aren’t a medical emergency. In fact, you often can treat them yourself. But see your healthcare provider if you have nosebleeds often. And seek care right away if you:

  • Have a head injury

  • Have bleeding that lasts more than 15 to 30 minutes or is severe

  • Feel weak or faint

  • Have trouble breathing

What to expect in the ER

  • You will be examined and may have blood tests.

  • You may be given medicated nose drops to stop the nosebleed.

  • The doctor may pack gauze into your nose to put pressure on the vessel and help stop bleeding.

  • The bleeding vessel may be cauterized. During this procedure, the vessel is burned with an electrical device or chemical. Your nose is first numbed so you won’t feel any pain.

  • In rare cases, you may need surgery to control the bleeding.

Home care for a nosebleed

  • Do not blow your nose for 12 hours after the bleeding stops. This will allow a strong blood clot to form. Do not pick your nose. This may restart bleeding.

  • Avoid drinking alcohol and hot liquids for the next 2 days. Alcohol or hot liquids in your mouth can dilate blood vessels in your nose. This can cause bleeding to start again.

  • Do not take ibuprofen, naproxen, or medicines that contain aspirin. These thin the blood and may cause your nose to bleed. You may take acetaminophen for pain, unless another pain medicine was prescribed.

  • If the bleeding starts again, sit up and lean forward to prevent swallowing blood. Pinch your nose tightly on both sides, as shown above, for 10 to 15 minutes. Time yourself. Don’t release the pressure on your nose until 10 minutes is up. If bleeding does not stop, continue to pinch your nose and call your healthcare provider or return to this facility.

  • If you have a cold, allergies, or dry nasal membranes, lubricate the nasal passages. Apply a small amount of petroleum jelly inside the nose with a cotton swab twice a day (morning and night).

  • Avoid overheating your home. This can dry the air and make your condition worse.

  • Put a humidifier in the room where you sleep. This will add moisture to the air.

  • Use a saline nasal spray to keep nasal passages moist.

  • Do not pick your nose. Keep fingernails trimmed to decrease risk of bleeds.

  • Do not smoke.
