Nosebleed That Won't Stop: How to Control It and When to Go to the ER

What is the right way to stop a nosebleed?

Follow these steps in order:

1. Sit upright and lean slightly forward — not backward. This prevents blood from draining down the throat. 2. Pinch the soft, fleshy part of your nose — below the bone — firmly with your thumb and index finger. 3. Hold for 10 to 15 full minutes without releasing to check. Use a clock. Most people check too early and restart the clotting process each time. 4. Breathe through your mouth. 5. Spit out any blood that drains into your mouth — do not swallow it. 6. Apply a cold pack or damp cloth to the bridge of your nose if that is comfortable. 7. After the bleed stops, avoid blowing your nose, bending over, or heavy lifting for several hours.

The American Academy of Otolaryngology–Head and Neck Surgery clinical guideline on epistaxis confirms that firm, sustained anterior compression for 10 to 15 minutes is the first-line intervention for most nosebleeds 1Ref 1Tunkel DE, Anne S, Payne SC, Ishman SL, Rosenfeld RM, et al. (2020).Clinical Practice Guideline: Nosebleed (Epistaxis) Executive Summary.First-line management of epistaxis with sustained anterior compression; indications for urgent/emergency care; posterior vs. anterior distinction.

When should you go to urgent care or the ER for a nosebleed?

Go to urgent care — or the ER if after hours — if:

• Bleeding has not slowed or stopped after 20 to 30 minutes of correct, steady pressure
• This is a second episode today
• You are on blood thinners (warfarin, apixaban, rivaroxaban, dabigatran) and bleeding will not stop
• You have a known bleeding disorder
• You are swallowing large amounts of blood or vomiting blood
• The bleeding started after a blow to the face or head
• You feel very dizzy or lightheaded from blood loss

Urgent care or an ER can pack the nose, cauterize the bleeding vessel, or identify a posterior nosebleed that cannot be controlled by pinching alone 1Ref 1Tunkel DE, Anne S, Payne SC, Ishman SL, Rosenfeld RM, et al. (2020).Clinical Practice Guideline: Nosebleed (Epistaxis) Executive Summary.First-line management of epistaxis with sustained anterior compression; indications for urgent/emergency care; posterior vs. anterior distinction3Ref 3U.S. National Library of Medicine (2023).Nosebleed.Patient-oriented guidance on nosebleed causes, home care steps, and when to call a clinician or seek emergency care; confirms pinch-and-lean technique and anticoagulant risks.

What is the difference between a front and back nosebleed?

Most nosebleeds are anterior — they start at the front of the nose, near the nostrils, where fragile blood vessels lie close to the surface. These respond well to pinching.

A smaller number are posterior — they start deeper in the nasal cavity, toward the back of the throat. Posterior nosebleeds tend to be heavier, harder to control, and more common in older adults and people on blood thinners. Blood flowing heavily down the back of the throat — especially if little or none is coming out the front — may signal a posterior nosebleed. This type usually requires medical treatment rather than home pressure alone 1Ref 1Tunkel DE, Anne S, Payne SC, Ishman SL, Rosenfeld RM, et al. (2020).Clinical Practice Guideline: Nosebleed (Epistaxis) Executive Summary.First-line management of epistaxis with sustained anterior compression; indications for urgent/emergency care; posterior vs. anterior distinction.

What causes nosebleeds, and how can you prevent them?

The most common causes are dry air (especially in winter or dry climates), nose picking, hard nose blowing, a cold or allergy, or a recent facial injury 3Ref 3U.S. National Library of Medicine (2023).Nosebleed.Patient-oriented guidance on nosebleed causes, home care steps, and when to call a clinician or seek emergency care; confirms pinch-and-lean technique and anticoagulant risks. Less commonly, nosebleeds can reflect high blood pressure, a clotting problem, or a medication side effect.

Blood pressure that is elevated — whether from longstanding hypertension or from the stress of the nosebleed itself — can make bleeding harder to control, though high blood pressure rarely causes nosebleeds by itself 2Ref 2Whelton PK, Carey RM, Aronow WS, et al. (2018).2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults.Role of elevated blood pressure in making nosebleeds harder to stop; blood pressure assessment as part of nosebleed evaluation.

To reduce recurrence: - Use a saline nasal spray or a thin layer of petroleum jelly inside the nostrils to keep the lining moist. - Use a humidifier in dry environments. - Avoid picking. - If you take blood thinners and have frequent nosebleeds, speak with your prescribing clinician about whether your medication balance is appropriate.

How do blood thinners change nosebleed management?

Anticoagulant and antiplatelet medications — including warfarin, apixaban, rivaroxaban, clopidogrel, and high-dose aspirin — significantly slow clotting. A nosebleed that would ordinarily stop in five minutes may bleed for an hour or more when these medications are involved 1Ref 1Tunkel DE, Anne S, Payne SC, Ishman SL, Rosenfeld RM, et al. (2020).Clinical Practice Guideline: Nosebleed (Epistaxis) Executive Summary.First-line management of epistaxis with sustained anterior compression; indications for urgent/emergency care; posterior vs. anterior distinction. Always tell urgent care or ER staff which blood thinners you take. Nasal steroid sprays aimed directly at the septum can also cause recurrent small bleeds; directing the spray away from the septum reduces this.
