Benign in the majority of cases, the nosebleed is a common phenomenon. However, it may sometimes constitute a medical emergency, so you should react accordingly.

Nosebleeds: a generally benign phenomenon

A nosebleed can be caused by a lesion in two types of blood vessels.

When small vessels rupture in the front of the nose (half an inch from the entrance to the nostril), the bleeding remains light. They aren’t worrisome and can be stopped easily. In this case, the epistaxis is described as benign.

More rarely, larger vessels can sustain lesions. If a blood vessel (or even an artery) located at the back of the nose starts bleeding, the flow is much more abundant. In this case, we’re talking about severe epistaxis, and it’s necessary to go the emergency room immediately.

Recognizing a benign nosebleed

In the case of benign epistaxis, the bleeding is light, often drop by drop. It occurs only in a single nostril, and your general condition isn’t affected. You just have to stop the effusion either by using an innovative treatment such as Nozohaem or by a traditional method (cold compress, nasal compression…).

When should you be worried?

We’re looking at severe epistaxis when the nosebleed is particularly abundant and affects both nostrils, or even causes significant blood flow in the throat. Generally, the effusion also affects the person’s general condition: pallor, dizziness, etc. In this situation, a visit to the emergency room is essential!

Furthermore, a significant or stubborn nosebleed can also be alarming if the person presents other risk factors, such as arterial hypertension, clotting problems, or kidney problems.

Finally, frequent and unexplained nosebleeds may sometimes mask an underlying disease. In this case, it’s best to see a doctor. Likewise, it should be checked if a serious nosebleed is caused by an injury.


A nosebleed is generally benign and corrects itself quickly. But if it’s too abundant or recurrent, it’s best to consult a doctor. We also suggest discussing this with your pharmacist during a visit to your pharmacy for sound advice.
