When to Worry (And Not Worry) About Nosebleeds

David Cuthbertson, MD


Nosebleeds seem to come at the worst times. No one wants to bleed — especially in public. And when a nosebleed strikes, it can be frustrating to manage. Maybe your nice dinner is abruptly interrupted with a nosebleed. You can’t get it to stop — and now there’s blood everywhere. If you’re lucky enough to make it to a bathroom, it still creates a mess.

Even a short or light nose bleed is frustrating. It ruins clothes, stains sheets, and always requires clean-up.

Nosebleeds are often harmless, but if they happen frequently, you may need to see a doctor. When is it time to worry about nosebleeds — and when is it just an inconvenience?

Here’s how to tell:

What Happens During A Nosebleed

Epistaxis, the medical term for nosebleeds, most often begins from the tissue in the anterior (front) of the nose. Usually, the bleeding comes from the center wall of the nose called the septum.

Multiple arteries intersect at a specific point on the septum called the Kiesselbach’s Plexus. This creates a high concentration of blood supply in one small area. If this area dries out, causing the skin to become chapped and cracked, it can bleed profusely.

Most of us have experienced something similar on our lips. If they’re too dry, our lips crack and bleed. But in this part of the nose, there’s a much higher blood supply, making it bleed much more heavily.

Typically, it happens like this: The skin dries out. The patient rubs, picks, or blows their nose and then, GUSH, nosebleed.

In very rare cases, nosebleeds are posterior. This type of nosebleed comes from the large artery in the back of the nose. These will not stop with at-home management techniques (described below). Posterior nosebleeds only stop when a medical professional inserts packing. In some cases, we opt for surgery to cauterize the vessel or we use embolization — where we block the blood vessels from the inside to stop bleeding.

What Causes Nosebleeds

While the reason for a nosebleed is simple (fragile skin was irritated and bled), certain factors definitely increase the likelihood of a nosebleed. In fact, when a nosebleed occurs, you can typically blame one of these five factors:


A dry climate wreaks havoc on the skin. Out in west Texas, we’re no strangers to nosebleeds caused by the climate. Dry air in general, however, can irritate the nose. Even turning the heat on in the winter can make the problem worse.

Digital Manipulation

Picking the nose obviously triggers nosebleeds, but even blowing or wiping the nose due to allergies or a cold can irate the area and initiate a nosebleed.

Nasal Steroid Sprays (and other allergy medications)

Flonase and other steroid sprays list nosebleeds as a potential side effect because these medications dry out the nose. To a milder extent, oral antihistamines (like Claritin, Zyrtec, or Allegra) can also contribute to nosebleeds.

Blood Thinners

Patients taking blood thinners can’t readily form a clot in their blood. This means the nosebleed won’t stop quickly.


An injury to the nose, particularly in this area of blood vessels, can easily trigger a nosebleed.

How To Stop a Nosebleed

If your nose begins to bleed, don’t panic. It’s a common occurrence that’s typically solved through a reliable sequence of steps. Here’s what you need to do:

1. Do NOT lean your head back.

Despite what you’ve heard, don’t tilt the head backward. You’ll swallow the blood as it drains back, which can make you throw up.

2. Lean your head forward.

Crane the neck forward as if you’re about to sniff.

3. Pinch the nose.

Using your fingers, pinch the soft part of the nose, squeezing the nostrils together. Most often, that’s where the bleeding is coming from. Use enough pressure to barely turn your fingernails white.

4. Hold the nose (constantly) for five minutes.

Don’t release the pressure. Watch the clock. It can feel like a long time but resist the urge to stop and check before your five minutes is up.

5. If it’s still bleeding, use decongestant spray.

Use Afrin or over-the-counter decongestant spray if the nose is still bleeding after five minutes of consistent pressure. Spray the decongestant directly in the nose, or soak a cotton ball with the medicine and insert the cotton ball into the nose.

Do not use Afrin preventatively. Only use it during an actual nosebleed.

6. Pinch the nose again.

Hold pressure for another five minutes.

You can repeat this 1-2 times if necessary.

In most cases, the nose stops bleeding by this point. However, if it’s still bleeding after several rounds of this process, it’s time to visit the emergency room.

What Won’t Stop a Nosebleed

When you’re dealing with nosebleeds, people try all sorts of quick treatments. But several are completely ineffective.

As you treat your nosebleed, avoid these common mistakes:

  • Pressure on the nasal bones
  • Ice pack on the neck (but an ice pack on the face could help!)
  • Leaning your head back

How to Prevent Nosebleeds in the Future

Ideally, people would choose to prevent nosebleeds from occurring altogether. While there’s no sure fix, these simple habits can help you prevent nosebleeds from occurring.

  1. Run a humidifier every night. It doesn’t matter if it’s cold or hot — you just need more moisture in the air. Hydration is key.
  2. Use saline spray 2-3 times per day. You can even use a saline gel spray if it’s more convenient.
  3. Trim your fingernails. Sharp nails irritate the skin if they touch this sensitive area.
  4. Resist picking, scratching, or rubbing your nose.
  5. Do not pick scabs. If you have a scab in the nose, apply saline until it naturally comes off. (We’ve actually seen patients pick holes through their septum!)
  6. Keep blood pressure under control.
  7. Avoid too much aspirin/ibuprofen. These mild blood thinners make it much more difficult for the blood to clot.

When To Worry About Nosebleeds

It’s difficult to distinguish between the inconvenience of a nosebleed — and an actual medical issue. And there’s no perfect answer to knowing it’s time to visit a medical professional to treat your nosebleed.

However, if nosebleeds progress to a point where they regularly disrupt your life, see your doctor. They’ll talk you through the options for treatment and prevention to get your nosebleeds under control.
