Medicine for a runny nose and congestion

A runny nose releases thin mucus when the nasal lining reacts to a virus, allergen, smoke, or another irritant. The common cold may also bring a sore throat and cough. Allergic rhinitis often causes repeated sneezing, itchy eyes, and symptoms linked to pollen, dust, or animals.

Sinusitis may cause facial pressure, reduced smell, or thicker discharge. Influenza and COVID-19 can include nasal symptoms along with fever, aches, cough, or fatigue. The symptom pattern and timing matter more than mucus colour alone.

Saline spray or a correctly prepared saline rinse can clear mucus and moisturise the nose. Rest, fluids, and avoiding smoke may also help. A pharmacist can advise about an antihistamine when allergy is likely, or a short course of a decongestant when congestion is the main problem.

Read combination cold-product labels so you do not duplicate ingredients. Ask before using decongestants if you have high blood pressure, heart disease, glaucoma, prostate symptoms, are pregnant, or take regular medicines. A nasal steroid may be considered for recurring allergy symptoms, but it should be used as directed and is not an instant fix.

Seek urgent help for severe breathing difficulty, swelling of the face or lips, blue lips, confusion, or extreme drowsiness. Arrange prompt medical advice for severe facial pain, swelling near an eye, persistent high fever, dehydration, or symptoms that worsen sharply after initial improvement.

Book a review when symptoms last longer than expected, recur without an obvious trigger, affect only one side, or repeatedly disrupt sleep. Testing for a respiratory infection may be advised when the wider symptoms suggest influenza or COVID-19.

Ask whether your symptoms fit an infection or allergy, which product is safe with your health history, and how long to use it before arranging a review.
