First Aid for Nosebleeds (Epistaxis)

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

A nosebleed occurs when the fragile blood vessels lining your nasal passages break and bleed. While most nosebleeds are harmless and resolve with simple first aid, proper technique is essential to prevent swallowing blood or causing rebleeding. Follow these clinically guided steps to safely stop a nosebleed at home and recognize when to seek medical help.

Quick Summary

Sit upright, lean slightly forward, and firmly pinch the soft lower 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

Keep your head elevated above the level of your heart to reduce venous pressure in your nasal vessels. Lean slightly forward from the waist so blood drains out through your nostrils rather than down the back of your throat.

Important: Do not tilt your head back or lie flat; swallowing blood can irritate the stomach lining, cause nausea or vomiting, and increase the risk of choking.

2

Clear any loose clots gently

If clots have formed and are partially obstructing your breathing, you may gently blow your nose once to expel them. This step is optional and should be done very softly to avoid aggravating delicate blood vessels.

Important: Do not aggressively blow or probe inside the nose, as this can dislodge forming clots and significantly worsen the hemorrhage.

3

Pinch the soft portion of your nose

Use your thumb and index finger to compress both nostrils firmly against the central cartilage (the nasal septum), just below the bony bridge. Breathe calmly through your mouth while maintaining constant, uninterrupted pressure for a full 10 to 15 minutes.

Important: Resist the urge to release pressure early to check if bleeding has stopped, as interrupting compression restarts the clotting process.

4

Apply a cold compress

Place an ice pack or a cold, damp cloth wrapped in a towel across the bridge of your nose and cheeks. The cold temperature promotes vasoconstriction, which narrows local blood vessels and helps slow blood flow.

5

Assess and repeat pressure if needed

After 15 minutes of continuous pinching, gently release your fingers to see if the bleeding has ceased. If bleeding continues, apply an over-the-counter decongestant spray containing oxymetazoline to the bleeding side if available, and pinch firmly for an additional 10 to 15 minutes.

Important: Decongestant nasal sprays should only be used as a short-term emergency measure and not continuously for more than 3 days without a doctor's advice.

6

Protect the nasal lining after clotting

Once the bleeding stops, rest quietly with your head elevated and avoid touching your nose. Do not blow your nose, bend over, or lift heavy objects for at least 12 to 24 hours to prevent disrupting the fragile clot.

7

Seek emergency medical evaluation when indicated

Go to an urgent care center or emergency department if bleeding persists beyond 20 to 30 minutes of continuous pressure, if you experience dizziness or faintness, or if the bleeding is exceptionally rapid. Immediate care is also required if the nosebleed was triggered by severe facial trauma.

Important: If you are taking prescription anticoagulants (blood thinners) and bleeding does not stop after 15 to 20 minutes, seek urgent medical attention.

Frequently Asked Questions

Why shouldn't I tilt my head back during a nosebleed?
Tilting your head back allows blood to run down the pharynx into your esophagus and stomach. Swallowed blood is an emetic that frequently triggers vomiting, and blood in the airway poses an aspiration hazard.
Should I pack cotton balls or tissue into my nostrils?
No. Packing dry tissues or cotton into the nostril can adhere to the raw vessel. When you pull the material out later, it usually tears the newly formed scab off, restarting the bleed. Direct external compression is far safer and more effective.
What are the most common causes of frequent nosebleeds?
The most frequent triggers are dry indoor air, cold weather, nose picking, allergic rhinitis, and frequent use of steroid or antihistamine nasal sprays. Less commonly, high blood pressure, bleeding disorders, or blood-thinning medications contribute.
How can I prevent nosebleeds from recurring in dry weather?
Keep the nasal mucosa hydrated by running a cool-mist humidifier in your bedroom, applying a thin layer of petroleum jelly or saline nasal gel just inside each nostril, and using gentle over-the-counter saline sprays daily.
