How to actually stop a nosebleed: firm pressure on the soft part for five minutes

The evidence-based way to stop a typical nosebleed is unglamorous and specific: apply firm, sustained pressure to the lower third of the nose — the soft part, not the bony bridge — and hold it for five minutes or longer. That is the first-line treatment for active bleeding in the American Academy of Otolaryngology–Head and Neck Surgery's 2020 nosebleed guideline [s1]. Most nosebleeds are minor and settle with simple measures like this; a Cochrane review notes that even in children, most cases are self-limiting or stop with something as basic as pinching the nose [s2].

Common, and mostly harmless

Nosebleed, or epistaxis, is close to universal: it happens at some point to at least 60% of people in the United States [s1]. The overwhelming majority never trouble a clinician. About 6% of people who get nosebleeds seek medical attention, epistaxis accounts for roughly 0.5% of all emergency department visits and up to a third of otolaryngology-related emergency encounters, and inpatient hospitalisation for aggressive treatment of a severe nosebleed is reported in just 0.2% of people who have them [s1]. The everyday nosebleed is, statistically, a nuisance rather than an emergency.

The technique the guideline actually endorses

The guideline's key action on a bleed in progress is precise about where and how long. It directs firm, sustained compression to the lower third of the nose, with or without help from the patient or a caregiver, for five minutes or longer [s1]. The two details that matter are the location and the clock. The lower third is the soft, compressible part; squeezing the hard bridge higher up does not press the bleeding vessels together. And five minutes is a floor, not an average — releasing early to check whether it has stopped is the most common way to restart a bleed that was about to clot.

If bleeding continues and a source can be seen, the guideline lists the next-line options a clinician may use: topical vasoconstrictors to shrink the vessels, chemical or electrical cautery of the bleeding point, and moisturising or lubricating agents [s1]. Only when compression fails to reveal or control a source does it move to nasal packing, and further still to cautery under direct vision or, rarely, procedures to tie off or block the feeding artery [s1]. The ladder is deliberately ordered so that the simplest thing is tried first, because for most people the simplest thing works.

Where the evidence for "more" gets thin

What is striking is how little high-quality evidence supports the treatments people escalate to once simple pressure has been tried. The Cochrane review of recurrent nosebleeds in children — the group most likely to be brought in for repeated bleeds — found only three eligible studies, 256 participants in all [s2]. They compared an antiseptic cream against no treatment, petroleum jelly against no treatment, and antiseptic cream against silver nitrate cautery [s2]. The results were inconclusive, with no statistically significant difference between the compared treatments, and the review concluded that the optimal management of recurrent childhood nosebleeds is simply unknown [s2]. Notably, no serious adverse effects were reported, though children who had silver nitrate cautery described it as painful even with local anaesthetic [s2].

That is not evidence that these treatments do nothing. It is evidence that the trials needed to rank them have not been done, which is a different and more honest statement than the confidence with which creams and cautery are sometimes offered.

When a nosebleed needs a doctor

Simple pressure handles the ordinary case; a nosebleed becomes a reason for medical help when it does not. The guideline frames prompt management around bleeding that is severe, persistent despite pressure, or recurrent, and it flags that repeated or bilateral bleeds, a personal or family history of bleeding disorders, and the use of anticoagulant or antiplatelet medication all raise the stakes and change what a clinician should do [s1]. Which intervention is right for a bleed that will not stop — and for anyone on blood thinners — is a clinical judgement this article does not attempt to make.
