When to worry about a runny nose with a common cold

A common cold can irritate the lining of the nose, causing clear or cloudy mucus, sneezing, congestion, and a scratchy throat. Mucus may become thicker as the illness continues; colour alone does not show whether antibiotics are needed. A runny nose should gradually settle as the cold improves. It can also occur with other infections or allergies, so the whole pattern matters.

Rest, drink fluids regularly, and use saline nasal drops or a gentle saline rinse to loosen mucus. Blowing your nose softly can reduce irritation. A humidified room may feel soothing, and avoiding cigarette smoke helps the nasal lining recover. Check with a pharmacist before using a decongestant, especially if you are pregnant or have high blood pressure, heart problems, or other long-term conditions. Do not give children medicines intended for adults.

Arrange medical advice if fever is persistent, symptoms are becoming more severe, facial pain is marked, or the illness improves and then clearly worsens. Seek urgent help for difficult breathing, bluish lips, unusual drowsiness, confusion, inability to keep fluids down, or signs of dehydration such as very little urine. Babies, older adults, and people with weakened immunity or significant lung disease may need earlier assessment.

Could this pattern be an allergy or another infection? Which nasal treatments are suitable for my age and health conditions? What changes should make me contact the clinic again?
