Home remedies for a cold and runny nose

A runny nose is fluid draining from irritated nasal lining. A common cold often brings clear mucus, sneezing, congestion, sore throat, or a mild cough. Allergies can cause repeated watery discharge with itching and sneezing, while influenza and COVID-19 may include stronger whole-body symptoms. A runny nose alone cannot tell you which condition is present.

Mucus may become thicker as irritation continues; colour by itself does not prove that antibiotics are needed. Consider recent contacts, seasonal triggers, and whether symptoms improve away from dust, pets, or other irritants.

Drink regularly and rest. Saline spray can loosen mucus; blow your nose gently, one side at a time, and use soft tissues to limit soreness. A warm drink or a comfortably humid room may ease irritation. Wash hands, cover coughs and sneezes, and avoid sharing cups while you are unwell.

A pharmacist can advise on symptom medicines, especially if you take regular treatment, are pregnant, or care for a child. Avoid combining products with the same active ingredient and do not give children adult preparations. Antibiotics do not treat viral colds.

Get urgent help for trouble breathing, bluish lips, severe dehydration, confusion, or swelling of the face or throat. Seek medical advice for chest pain, a persistent high fever, severe weakness, symptoms that improve then become markedly worse, or a runny nose after a head injury. Consider testing or guidance if COVID-19 or influenza exposure is possible.

Does this pattern fit a cold or allergy? Which symptom medicine is safe with my other medicines? Should I test for COVID-19 or influenza, and when can I return to work or school?
