Quick nasal congestion relief

A [Blocked Nose](/symptoms/blocked-nose/) happens when swollen lining or mucus narrows the nasal passages. A cold, [Allergic Rhinitis](/conditions/allergic-rhinitis/), sinus inflammation, or irritants can cause it. Recurrent congestion may be linked to dust-mite allergy or chronic sinusitis. Snoring and restless sleep, especially with pauses in breathing, warrant consideration of obstructive sleep apnoea.

Use a saline spray or rinse with water prepared exactly as the product directs, drink fluids, and add moisture to dry indoor air. Avoid smoke and known allergens; washing bedding regularly may help when dust is a trigger. A pharmacist can advise on [Allergy Medication](/treatments/medical-management/allergy-medication/) if sneezing and itchy eyes accompany congestion. Do not use a decongestant spray longer than its instructions, because overuse can make blockage return. Check oral decongestants carefully if you have high blood pressure, heart disease, or take regular medicines.

Arrange a review if congestion lasts beyond a usual cold, repeatedly affects one side, causes facial pain, or comes with reduced smell that does not recover. Seek urgent help for severe breathing difficulty, swelling around an eye, confusion, a severe headache, or a high fever with marked illness. Nighttime choking or witnessed breathing pauses also need assessment.

Ask whether the pattern suggests allergy, sinusitis, a structural blockage, or another cause; which spray is suitable; and how to use a rinse safely. Mention snoring, mouth breathing, nosebleeds, medication use, and symptoms that are worse in a particular room.
