Allergic rhinitis/hay fever is caused when the body’s immune system makes an allergy antibody (IgE) to a normal substance such as pollen, house dust mites, pets or moulds (allergens). With people sensitive to these allergens, exposure causes the release of chemicals from cells in the nasal passages airways, and eyes. This results in irritation and inflammation to the lining of the eyes, nose and throat. Grass pollen is the most common allergen, which affects sufferers at the specific times of the year when grass pollen is released (late April–July). However, some people are allergic to tree or weed pollens or mould spores and will therefore be affected at different times of the year (February–June for trees; May - September for weeds; and moulds for much of the year). The patient who is allergic to tree, grass, weed pollens and mould spores may suffer a very prolonged ‘hay fever’ season. The correct term for allergic rhinitis which occurs for part of the year is ‘seasonal allergic rhinitis’. Symptoms that continue all year are ‘perennial allergic rhinitis’ and commonly relate to indoor allergens such as house dust mites, pets and indoor moulds. Symptoms Symptoms include sneezing, itchy, runny nose, and irritation of the roof of the mouth, deep in the ears and in the back of the throat. The subsequent inflammation (swelling and redness) causes a stuffy nose and sinus congestion, which make sleeping difficult and can cause headaches. The eyes may itch and water and become swollen, red and sore (allergic conjunctivitis). Management and Treatment Allergic rhinitis/hay fever is often regarded as a trivial problem but it severely affects many people’s quality of life. It disturbs sleep, and impairs daytime concentration and the ability to carry out everyday activities, including driving. It causes people to miss work or school, can have a detrimental effect on exam results, and ruins people’s social lives. People with allergic rhinitis/hay fever often have asthma or are at increased risk of developing asthma. Inflammation in the nose, which is the first part of the airway, often affects the rest of the airways that lead to the lungs. Asthmatics who also suffer allergic rhinitis/hay fever may have less severe asthma and fewer A&E and hospital admissions if their allergic rhinitis/hay fever is treated effectively. Management - Allergen avoidance Pollens and mould spores are windborne and travel for miles on air currents so are difficult to avoid but some simple measures can help. Avoidance of house dust mite and pet allergen requires dedicated complex measures in the home to reduce symptoms. Treatments Anti-histamines suppress histamine release so give quick relief for mild symptoms. Nonsedating tablets or liquid may be taken daily by mouth but are not as effective as nasal sprays and eye drops, used regularly. Cromoglycate eye drops also help, used several times daily. For more severe eye inflammation, it is essential to see a doctor. For persistent or more severe nasal symptoms, the regular use of an antiinflammatory nasal spray is required. These contain miniscule doses of steroid medication which are effective as they are sprayed directly to the inflamed mucous membrane (lining) of the nose, usually twice daily. These sprays are available from pharmacists or on prescription from your GP. It is essential to use them correctly (see instructions below). For the most effective results for seasonal symptoms (allergic rhinitis/ hay fever) start the treatment before your symptoms normally occur doctors recommend two to four weeks. Anti-histamines or nasal sprays can be used for symptom relief. Newer treatments such as nasal sprays containing anti-histamines and corticosteroids may be prescribed for moderate to severe symptoms. Nasal sprays that contain decongestants may be useful for weddings, flying or exams but should not be used regularly, as they can make symptoms worse if used frequently. How to use a nasal spray correctly: 1. Shake the bottle 2. If nose is blocked, use nasal douche and blow nose 3. Look down, keep chin on chest 4. With bottle in right hand, spray into left nostril away from centre. Sniff GENTLY 5. With bottle in left hand, spray into right nostril away from centre. Sniff GENTLY 6. If two drops needed in each side, repeat as above Allergic Rhinitis/Hay Fever Symptom Checker 1. Do you suffer with some of the following symptoms: sneezing/runny nose/stuffy nose/catarrh/itchy red swollen eyes/itching deep inside ears and throat/itching roof of mouth? Yes/No 2. Do you also suffer with any of the symptoms of asthma, i.e. wheezing/ tight chest/cough/shortness of breath? Yes/No If you have answered ‘No’ to questions 1 and 2 you will not need to answer any further questions. If ‘Yes’ go to Question 3. 3. Do you suffer with several of the following symptoms? Sneezing Runny nose Itchy/watery/red or swollen sore eyes Itching deep inside ears/roof of mouth/throat Stuffy nose/sinusitis Catarrh Cough Wheezing/shortness of breath/tight chest Y/N Y/N Y/N Y/N Y/N Y/N Y/N Y/N 4. Do you experience these symptoms for: Several days a week Y/N 5. Have your symptoms lasted for: More than two consecutive weeks Y/N 6. What time of year do you have symptoms which affect your normal life activities (work/school/ exercise/sleep)? January - March April - August September - December Y/N Y/N Y/N What do your answers mean? Please use this symptom checker as a guide when talking to your doctor. If you have answered ‘Yes’ to Q4 and Q5, you should seek advice from your doctor, as there are treatments that can improve your symptoms and quality of life, and prevent your condition becoming worse. Q6 - If your symptoms occur: • April to August this suggests outdoor allergens such as pollens, weeds and moulds could be a trigger • September to March this suggests indoor allergens such as house dust mite, pets and moulds.
