I’m receiving chemotherapy and now have a nosebleed—how should I manage it and when is emergency evaluation required?

Management of Nosebleed During Chemotherapy

If you develop a nosebleed during chemotherapy, immediately apply firm, continuous pressure to the soft lower third of your nose for a full 10-15 minutes without checking if bleeding has stopped, and seek emergency evaluation if bleeding persists beyond 15 minutes, you develop signs of hemodynamic instability, or you have evidence of significant blood loss. 1

Immediate Self-Management Steps

Apply direct nasal compression as first-line treatment:

• Pinch the soft lower third of your nose firmly and continuously for 10-15 minutes without releasing to check if bleeding has stopped 1
• Sit upright with your head tilted slightly forward to prevent blood from flowing into your airway or stomach 1
• Breathe through your mouth and spit out blood rather than swallowing it 1
• This compression technique alone resolves the vast majority of anterior nosebleeds 1

If bleeding continues after 15 minutes of proper compression:

• Apply 2 sprays of over-the-counter oxymetazoline (Afrin) or phenylephrine into the bleeding nostril 1
• Resume firm compression for another 5-10 minutes after applying the vasoconstrictor 1
• Topical vasoconstrictors stop bleeding in 65-75% of emergency department cases 1

When to Seek Emergency Evaluation

Go to the emergency department immediately if any of the following occur:

• Bleeding persists after 15 minutes of continuous proper compression 1
• Total bleeding duration exceeds 30 minutes within a 24-hour period 1
• You develop signs of hemodynamic instability: tachycardia, syncope, lightheadedness, or orthostatic hypotension 1, 2
• Bleeding comes from both nostrils or you taste blood in the back of your throat (suggests posterior source) 2
• You develop airway compromise from blood in the oropharynx 1

Chemotherapy patients are at particularly high risk because:

• Chemotherapy commonly causes thrombocytopenia (low platelet counts), which impairs normal clotting mechanisms
• Many chemotherapy regimens damage nasal mucosa, making it more fragile and prone to bleeding
• The combination of mucosal injury and platelet dysfunction creates a higher risk of severe, difficult-to-control epistaxis

Hospital-Based Management

If you present to the emergency department, expect the following evaluation and treatment:

Initial Assessment

• Healthcare providers will measure your blood pressure, as approximately 33% of epistaxis patients have underlying hypertension 1
• They will assess for hemodynamic stability and check your platelet count and coagulation studies
• Documentation should include your chemotherapy regimen, recent platelet counts, and any history of bleeding disorders 3

Escalating Interventions

If compression and vasoconstrictors fail:

• Nasal endoscopy will be performed to identify the bleeding source, which localizes the site in 87-93% of cases 1, 2
• If a focal bleeding point is identified, cauterization may be performed after topical anesthesia 1
• Electrocautery is more effective than chemical cauterization, with recurrence rates of 14.5% versus 35.1% 1

If bleeding continues despite cautery:

• Nasal packing will be placed using only resorbable/absorbable materials (Nasopore, Surgicel, Floseal) 1
• This is critical in chemotherapy patients with thrombocytopenia, as non-resorbable packing can cause trauma during removal 1
• Nasal packing is indicated when bleeding persists after 15-30 minutes of proper compression with vasoconstrictors, for life-threatening bleeding, or when a posterior source is suspected 1

For refractory bleeding:

• Topical tranexamic acid applied to the nasal mucosa shortens time to hemostasis (average 6.7 minutes versus 11.5 minutes) and lowers recurrence rates (6% versus 20%) 1
• If packing fails, evaluation for surgical arterial ligation or endovascular embolization should be considered 1
• Endoscopic sphenopalatine artery ligation has a 97% success rate compared to 62% for conventional packing 1
• Endovascular embolization has an 80% success rate with recurrence rates less than 10% compared to 50% for nasal packing 1

Prevention After Bleeding Stops

Once hemostasis is achieved, implement these preventive measures:

• Apply petroleum jelly or nasal saline gel to the anterior nasal mucosa 2-3 times daily to maintain moisture and reduce recurrence 1, 4
• Use saline nasal sprays frequently throughout the day to keep nasal mucosa moist 1
• Use a humidifier in your bedroom, as dry heat creates fragile, hyperemic nasal mucosa that bleeds easily 1, 5
• Avoid nose blowing, strenuous activity, and nasal manipulation for at least 7-10 days 1

A study of 74 anticoagulated patients with recurrent anterior epistaxis found that nasal saline gel as monotherapy achieved cessation of bleeding in 93.2% at 3 months, demonstrating the effectiveness of simple mucosal moisturization in preventing recurrence. 4

Critical Pitfalls to Avoid

Do not prematurely release compression:

• The most common cause of treatment failure is checking if bleeding has stopped before completing the full 10-15 minutes of continuous pressure 1

Do not use topical vasoconstrictors repeatedly:

• Prolonged use can cause rhinitis medicamentosa, loss of efficacy, and worsening nasal obstruction 1

Do not delay seeking care if bleeding persists:

• Chemotherapy-induced thrombocytopenia means your blood will not clot normally, and bleeding that would be self-limited in others may become life-threatening in your case
• The 30-day all-cause mortality rate for posterior epistaxis is 3.4%, highlighting the potential severity 6

Special Considerations for Chemotherapy Patients

Coordinate with your oncology team:

• Your oncologist should be notified of any significant bleeding episode, as this may affect timing of future chemotherapy cycles
• Platelet transfusion may be considered if your platelet count is critically low (typically <10,000-20,000/μL) and bleeding is severe
• Your chemotherapy regimen may need dose adjustment or delay if recurrent severe epistaxis occurs

Follow-up is mandatory:

• Routine follow-up within 30 days is recommended for patients who have undergone invasive treatments to assess for complications and recurrent bleeding 1
• Document outcomes to improve individual patient care and identify patterns that may require chemotherapy modification 3
