Allergy symptoms:
Causes and management

It doesn’t matter whether allergy symptoms are mild or severe, seasonal or constant, they can make day-to-day life difficult.5 Here’s everything you need to know about allergies and keeping them in check.

What are allergies and allergens?

The technical term for nasal allergies is ‘allergic rhinitis’, but we’re all probably more familiar with the term ‘hayfever’. Hayfever is caused by specific environmental triggers called allergens. These often include:6


Dust mites


Grass or tree pollen




Mould spores

Depending on the allergen, your symptoms might occur seasonally or all year round.6


Allergy symptoms

Hayfever mainly affects the eyes and nose, with symptoms often including:6


Nasal congestion




A runny nose


Itchy or watery eyes


An itchy nose


Symptoms can range from mild to severe and, if not managed properly, can also lead to:


Disrupted sleep




Daytime fatigue


An inability to concentrate




What is the difference between an allergy or a cold?

Hayfever or allergies share many of their symptoms with the common cold, which can cause some confusion – but there are some key differences.7


Bear in mind that allergy symptoms also tend to continue until they’re treated properly. So, where your average cold tends to last between 3 and 14 days, allergies can persist for weeks at a time and even entire seasons.7

Managing allergies

Limiting contact with your trigger can be an effective way to minimise allergic reactions.9

Treatment options

While allergy minimisation strategies may help in relieving mild allergy symptoms, moderate to severe or frequent symptoms may need managing with medications or other therapies.6

Intranasal corticosteroid nasal sprays (INCS), like Nasonex®  Allergy, are powerful allergy treatments and prevention sprays. They work at the source to relieve the nasal inflammation caused by hayfever allergens and are recommended as a first-line treatment option for moderate to severe allergies.6,10

Other over-the-counter treatments available include:6

Antihistamine tablets for daily relief of mild allergies.

Decongestant sprays and tablets for short-term relief of nasal congestion.

Non-medicated products, such as saline nasal sprays, to help cleanse the nasal passage.
