What should you know about drugs for runny nose?

Clear discharge with sneezing, itchy eyes, or symptoms after contact with pollen, pets, or dust can fit an allergic pattern. A cold, influenza, or COVID-19 may bring a runny nose alongside sore throat, cough, fever, or tiredness. Facial pressure, reduced smell, and thick discharge can occur with sinusitis. A symptom alone does not identify the cause.

Antihistamines can reduce allergy-related dripping and sneezing. Saline rinses or sprays may help clear mucus. Decongestant products are not suitable for everyone and some nasal sprays should not be used beyond the period on the label, because congestion can rebound.

Drink normally, rest, and use tissues gently to protect sore skin. A saline spray or rinse may provide comfort; use clean water prepared as directed for any rinse. Ask a pharmacist before using an antihistamine or decongestant if you are pregnant, have high blood pressure, glaucoma, heart problems, or take regular medicines.

Check active ingredients in combination cold remedies to avoid taking the same ingredient twice. Consider an allergy consultation if symptoms recur around a pet or dusty room, and test for an infection when advised by local guidance or a clinician.

Seek prompt assessment for trouble breathing, swelling of the lips or tongue, severe facial pain, confusion, dehydration, or a high fever with marked illness. Arrange medical advice if discharge is bloody or one-sided after an injury, symptoms persist or worsen, or you have breathing disease that is becoming harder to control.

Ask what pattern best fits your symptoms, whether an antihistamine or nasal treatment is appropriate, and how long to use it. Check whether your regular medicines or health conditions change the choice, and ask which symptoms require testing or review.
