Side Effect: Runny Nose (Rhinorrhea)

A runny nose, also known as rhinorrhea, is a common symptom characterized by an excess production and discharge of mucus from the nasal passages.

• The discharge from a runny nose may be clear and watery, thick and yellow or green, or bloody.
• When it is clear and watery, it may be due to a viral infection, allergies, or simply from moving between warm and col environments.
• In some cases, the discharge may be thick and either green or brownish, which may indicate a bacterial infection.

• A runny nose can be caused by various factors, including allergies, infections, or irritants such as smoke or pollution.
• Patients with cancer can develop a runny nose as a result of several factors:
  • Chemotherapy drugs can cause irritation and inflammation of the nasal passages, leading to a runny nose
  • Radiation therapy can also cause inflammation and damage to the nasal tissues.
  • Additionally, certain types of cancer, such as nasal or sinus cancers, can cause a runny nose as a symptom.

Preventing a runny nose can be challenging; however, some strategies may help reduce the severity of symptoms:

• Avoiding irritants such as cigarette smoke, dust, and pollen can help prevent nasal irritation and inflammation.
• Using a humidifier or saline nasal spray may help moisturize the nasal passages and reduce dryness.
• Maintaining good hygiene practices such as washing hands frequently and avoiding contact with individuals who are sick can help avoid illnesses.

Treatment for a runny nose depends upon the underlying cause.

• If the runny nose is due to an infection, antibiotics may be prescribed if it is believed to be a bacterial infection and not a viral infection.
• Antihistamines or decongestants may also be used to reduce inflammation and congestion.
• In some cases, nasal corticosteroids may be recommended to reduce inflammation.
