Nasacort Allergy Relief

Nasacort is a once-daily corticosteroid nasal spray formulated to relieve the symptoms of hay fever and allergic rhinitis, including sneezing, itchy nose, blocked nose and runny nose. The active ingredient, triamcinolone acetonide, works by reducing inflammation inside the nasal passages, offering long-lasting relief for adults and children experiencing seasonal or year-round allergies.

What is Nasacort?

Nasacort contains triamcinolone acetonide, a corticosteroid designed for localised use inside the nose. Unlike oral antihistamines, which work systemically, Nasacort acts directly at the nasal lining — the area where allergy symptoms begin. It can be used for:

• Seasonal allergic rhinitis (hay fever caused by pollen).
• Perennial allergic rhinitis (dust mites, pet allergens, mould).
• Persistent congestion not adequately controlled with oral antihistamines alone.

On Welzo, Nasacort is part of our wider allergic-rhinitis treatment range alongside hay fever & allergy, hay fever nasal sprays, and sore throat relief collections, helping you build a complete care plan during peak allergy seasons.

Benefits and features of Nasacort

• 24-hour relief from sneezing, blocked nose, itchy nose and runny nose.
• Anti-inflammatory action reduces swelling inside the nasal passages.
• Non-drowsy formula suitable for daytime use.
• Once-daily dosing for simplicity and adherence.
• Suitable for adults and children aged 2+ (depending on product strength).
• Works well alongside other supportive products from our allergy eye drops and children’s hay fever relief collections.

Why effective nasal allergy relief matters

Nasal allergies can significantly affect wellbeing by disrupting sleep, concentration, productivity and daily comfort. When the nasal lining becomes inflamed through exposure to allergens, symptoms such as congestion, sneezing and dripping can become persistent or severe. If untreated, this can worsen fatigue, irritability and sinus discomfort.

Nasacort helps manage inflammation at the source, providing 24-hour control during high-pollen periods or exposure to indoor triggers. It is commonly used when oral antihistamines alone are not sufficient or cause unwanted drowsiness.

How to use Nasacort safely

Always follow the instructions provided in the patient information leaflet. General guidance includes:

• Shake the bottle well before use and prime the spray as instructed.
• Insert the nozzle into one nostril, keeping your head upright, and spray while gently breathing in.
• Adults and children 12+ typically use two sprays per nostril once daily during initial treatment.
• Once symptoms improve, the dose may be reduced to one spray per nostril daily.
• Children aged 2–5 should only use children's formulations with professional guidance.
• Do not exceed the stated daily dose.
• Use regularly for best effect — corticosteroid sprays work cumulatively, not instantly.

If symptoms persist after 14 days of use, consult a doctor or pharmacist for further evaluation. Consider exploring additional options from our hay fever tablets range if combination therapy is appropriate.

Trust, quality and responsible use

Corticosteroid nasal sprays are safe and effective when used at the recommended dose. However, long-term or excessive use can increase the risk of nasal irritation, dryness or minor nosebleeds. They should not be used for sudden severe symptoms without medical advice.

Seek urgent help if you experience facial swelling, breathing difficulty, worsening sinus pain, persistent fever, or symptoms that do not improve after the recommended treatment period.
