What should you know about medicine for a stuffy nose from allergies?

Allergic nasal congestion often comes with sneezing, an itchy nose, clear discharge, or watery and itchy eyes. Symptoms may flare after contact with dust, pollen, mould, animals, or another personal trigger. Congestion with fever, body aches, thick discharge, or facial pain may point to an infection instead, although symptoms can overlap.

Different medicines target different symptoms. Some reduce the body's allergy response, while nasal treatments can reduce inflammation inside the nose. A medicine that helped someone else may not suit you, especially with pregnancy, high blood pressure, glaucoma, or other conditions.

Ask a pharmacist or clinician to help choose an option and check the label for age restrictions, drowsiness, interactions, and correct technique. Nasal sprays work best when used exactly as directed; aim the nozzle slightly away from the centre wall of the nose and avoid sharing it. Saline spray or rinse can remove irritants and may complement allergy treatment when used safely.

Reduce exposure by keeping the bedroom clean, washing after outdoor exposure, and avoiding known triggers where practical. If symptoms recur, write down the setting and timing so the pattern can be reviewed.

Seek urgent help for swelling of the lips or tongue, trouble breathing, faintness, or a rapidly spreading allergic reaction. Arrange medical review for severe facial pain, eye swelling, vision changes, repeated nosebleeds, persistent one-sided blockage, or symptoms that remain troublesome despite correct treatment.

Ask which medicine fits your symptoms and other medicines, how long to try it, how to use a nasal spray, and whether recurring congestion needs allergy assessment or a different diagnosis.
