First Aid for a Nosebleed (Epistaxis)

Published: October 19, 2026Updated: October 19, 2026

A nosebleed occurs when fragile blood vessels lining the inside of your nasal passages break and bleed. Most episodes are harmless and can be managed rapidly at home using direct pressure and proper posture. Following the correct first aid steps stops the bleeding and prevents complications like choking or nausea.

Quick Summary

Sit upright, lean slightly forward, and pinch the soft part of your nose continuously for 10 to 15 minutes while breathing through your mouth.

Step-by-Step Guide

1

Sit Upright and Lean Forward

Sit down comfortably and lean your head and upper body slightly forward. This position lowers venous pressure in your nose and prevents blood from running down the back of your throat. Swallowing blood can irritate your stomach lining and trigger nausea or vomiting.

Important: Do not tilt your head back or lie down flat, as this can cause blood to drain into your airway or stomach.

2

Pinch the Soft Part of the Nose

Use your thumb and index finger to firmly pinch both nostrils closed against the central nasal septum. Compress the soft, fleshy portion of the nose directly below the hard nasal bone. Applying pressure here compresses Kiesselbach's plexus, the network of blood vessels where most nosebleeds originate.

3

Maintain Continuous Pressure for 10 to 15 Minutes

Breathe gently through your mouth and hold continuous, firm pressure for at least 10 to 15 minutes timed with a clock. Resist releasing your grip early to check whether the bleeding has stopped. Removing pressure too soon can disrupt the delicate blood clot that is trying to form.

4

Apply a Cold Compress

Place an ice pack or a cold, damp cloth over the bridge of your nose or across the back of your neck while maintaining pressure. Cold temperatures stimulate vasoconstriction, which narrows local blood vessels and reduces blood flow. Always wrap ice packs in a thin towel to avoid freezing the skin.

5

Release Gently and Rest

After 15 minutes of uninterrupted pressure, slowly release your nostrils to verify that bleeding has resolved. Remain sitting quietly upright and refrain from bending over or straining for the next few hours. Do not blow, pick, or rub your nose, as these actions can easily dislodge the newly formed clot.

Important: Do not pack the inside of your nose with tissues, paper towels, or cotton balls, as removing them can re-tear the healing blood vessels.

6

Reapply Pressure or Seek Medical Care if Unresolved

If bleeding continues after the first 15 minutes, reapply firm pressure for another 10 to 15 minutes. If bleeding persists beyond 20 to 30 minutes despite continuous pressure, seek immediate emergency medical care. Professional treatment may require nasal packing, cautery, or prescription intervention.

Important: Seek emergency medical help immediately if you feel dizzy or faint, have difficulty breathing, or if the bleed was triggered by major facial trauma.

Frequently Asked Questions

Why shouldn't you tilt your head back during a nosebleed?
Tilting your head back allows blood to pool down the throat and into the stomach or airway. This can cause coughing, choking, or vomiting, and makes it impossible to monitor how much blood you are losing.
Can I use an over-the-counter nasal decongestant spray to stop bleeding?
Yes, a decongestant spray containing oxymetazoline can be sprayed into the bleeding nostril just before pinching to constrict the blood vessels. However, this should only be used as a temporary emergency measure, not as a frequent routine treatment.
When should I go to the emergency room for a nosebleed?
Go to the emergency department if bleeding lasts longer than 20 to 30 minutes despite direct pressure, if the bleeding is exceptionally heavy, if you feel lightheaded or short of breath, or if you take prescription blood thinners.
How can I prevent recurrent nosebleeds?
Prevent nosebleeds by keeping the nasal passages hydrated with saline nasal sprays or a thin layer of petroleum jelly, using a cool-mist room humidifier, and avoiding vigorous nose blowing or picking.
