Hay Fever

Every summer, up to 1 in 5 people in Britain are affected by hay fever. Also known as seasonal allergic rhinitis, hay fever is caused by an allergy to pollen and fungal spores. The allergy typically occurs in the mucous membranes of the nasal passages and eyes, explaining the occurrence of the symptoms described below such as sneezing, itchy eyes and a blocked or runny nose.

Pollen affects a hay fever sufferer because their body’s immune system over-reacts to it, as if it were a toxic substance. The symptoms of hay fever usually start to occur when the pollen count, the number of pollen grains per cubic metre of air, exceeds 50. As a result, the weather can affect how severely a sufferer experiences symptoms – sun can raise the pollen count, wind can spread pollen and rain can lower the count.

For many, the symptoms of hay fever are irritating in every sense. Different people react in different ways, but the most common symptoms are:

• Watery or itchy eyes
• Sneezing
• Runny or blocked nose
• Coughing
• Itchy feeling in the throat
• Wheezing

As hay fever is a chronic condition, there is no ‘cure’. In most people the symptoms of hay fever will ease, to some extent, as they get older. In up to 20% of people they can disappear completely.

As mild to moderate hay fever can usually be effectively controlled with over-the-counter medicines and advice from the pharmacy, no formal diagnosis is usually necessary. As long as treatment is effective and symptoms are well-controlled, there is no need to see a doctor.

However, if symptoms are severe, they occur indoors or during winter or cause other complications, a formal diagnosis and further investigations by a doctor may be required. Allergy testing by either a skin prick test or a blood test can help to reveal the cause of the allergy and help to form a management plan.

Hay fever is more common in people with eczema and other skin conditions, those who suffer with asthma, have a family history of hay fever and in those subjected to tobacco smoke at a young age.

Hay fever treatment can be very individual and depends very much on the type and severity of symptoms you experience. For mild to moderate hay fever symptoms, over-the-counter hay fever tablets, eye drops and nasal sprays may be enough to keep symptoms contolled. Patients who experience more severe hay fever symptoms that have a significant impact on their daily life may wish to seek prescription hay fever treatment.

Hay Fever Tablets (antihistamines)

Hay fever symptoms are caused by histamine. Histamine is released in response to allergens such as pollen from grass and trees. Hay fever tablets contain drugs such as loratadine and cetirizine, which are antihistamines that block the release of histamine. By regularly taking antihistamines, hay fever tablets you can block your body’s reaction to pollen and prevent symptoms from occurring and ease current symptoms.

Hay fever tablets are the most popular hay fever treatment, as they are usually taken once daily with few side effects. Tablets usually help with a broad range of hay fever symptoms and can be enough to keep you symptom free without additional treatment.

The prescription hay fever tablets that are available from The Independent Pharmacy are Telfast, containing fexofenadine, and Xyzal, which contains levocetirizine. We are also able to offer over-the-counter hay fever tablets containing the well-known antihistamines including cetirizine, loratadine, and chlorphenamine. Common over-the-counter brands of hay fever tablets include Benadryl, Clarityn, Piriton and Zirtek as well as the generic treatments.

Hay Fever Nasal Sprays (corticosteroids & antihistamines)

Nasal symptoms of hay fever such as sneezing, and a blocked or runny nose occur very frequently in hay fever sufferers. In some people, hay fever tablets will be enough to treat these symptoms, however if symptoms are more severe the addition of a hay fever nasal spray may be necessary. These nasal symptoms occur due to the swelling and inflammation of the lining of the nasal passages in response to histamine release. Nasal sprays for hay fever can be used on their own or in addition to hay fever tablets and eye drops.

Hay fever nasal sprays usually contain a corticosteroid (steroid), which helps to reduce inflammation and calm the irritation in the nasal lining. As hay fever steroid nasal sprays are applied to the area of action, they can be administered in very low doses and still be extremely effective. This means that they are unlikely to cause any side effects and still provide relief from the nasal symptoms of hay fever.

Steroid hay fever nasal sprays include one of the steroids; budesonide, fluticasone, mometasone or beclometasone. The prescription steroid hay fever nasal sprays available from The Independent Pharmacy include Dymista, Flixonase, Nasonex, and Rhinocort. Dymista nasal spray contains a combination of a steroid and an antihistamine for dual relief of symptoms. We are also available to offer over-the-counter hay fever nasal sprays containing the steroids beclometasone or fluticasone. Common over the counter brands of hay fever nasal sprays include Beconase and Pirinase as well as the generic treatments.

Antihistamine hay fever nasal sprays, such as Rhinolast, contain the antihistamine azelastine. Azelastine works in a similar way to antihistamine tablets to prevent histamine release and the subsequent allergy caused by it. However, it is applied directly to the nasal passages from the nasal spray so can be administered in much lower doses and works in the area where it is needed.

Hay Fever Eye Drops (antihistamines)

For people who experience the symptoms of hay fever mainly in their eyes, as running and/or itching, hay fever eye drops may be the most appropriate treatment. Hay fever eye drops such as Opticrom, Optilast and Rapitil all prevent the release of histamine in response to pollen and other allergies and thus help to both relieve and prevent symptoms.

The hay fever eye drops contain the drugs sodium cromoglicate (Opticrom), azelastine (Optilast) and nedocromil sodium (Rapitil). They are each used up to four times daily in each eye depending on response and severity of symptoms. Opticrom, Optilast or Rapitil can be used in combination with hay fever tablets and nasal sprays to help fully control symptoms.

Identify the allergen

Hay fever is typically caused by airborne allergens that enter the body through the air we breathe and trigger a severe response from the immune system. If it is highly seasonal, pollen grains and mould spores are the likeliest culprits. By careful observation, or by taking patch tests with the help of a doctor, it is possible to pinpoint the allergen. It will help you take precautions to prevent future attacks.

Reduce exposure

If you know the specific allergen, it is easier to reduce exposure. Otherwise, noticing whether you are getting it when certain flowers are in bloom or when grass has been freshly cut, if it is getting worse at a particular time of the day or during a specific activity, can help you avoid those situations.

Stay indoors when pollen counts are high

There is daily as well as seasonal fluctuation in pollen and mould counts in the air. Most weather shows broadcast the counts. Make it a point to listen to these reports, and avoid outings on particularly bad days. As a rule, pollen counts are high during the mornings and subside by afternoon. Plan your day accordingly. If you need to go outside when there is a high pollen count, ensure you take medication to help your allergies and wear sunglasses to prevent pollen getting in your eyes. Remember, a pollen count of over 50 may worsen hay fever symptoms.

Change and shower when you come inside

Avoid bringing outside allergens into the house as much as possible. Our clothes and hair are good carriers of these particles. Change outdoor clothes immediately on reaching the home, and take shower to wash off any pollen grains sticking to the body.

Change bed covers frequently

Since we spend a lot of time sleeping, pillow covers and bed covers should be kept as free of allergens as possible. Doctors advise those with severe allergies to cover the bedding with a hypoallergenic, non-permeable barrier and change the bedcovers every day.

Avoid other irritants

Common airway irritants like dust and smoke, especially tobacco smoke, may put your body in high alert towards allergens and make a hay fever attack more likely. Avoid exposure to these where possible.

Get efficient air purifiers

Install a high-efficiency particulate arresting filter (HEPA) into your air-purifier for better protection. The filter device itself can become a breeding ground for mould spores that can undermine the very purpose. Keep it in prime condition with regular servicing.

Delegate cleaning jobs to others

Indoor and outdoor cleaning jobs that typically throw allergens into the air should not be attempted by a person prone to hay fever. Cleaning the carpets, dusting the furniture, raking leaves, turning compost etc. should be delegated to other members of family or to outside help.

Dry clothes inside with the windows closed

As previously stated, pollen sticks to clothes so do not hang your laundry up to dry outside. Instead, keep it indoors at all times and ensure the windows are closed to prevent pollen coming into the house.

Keep allergy medication handy

Anyone with a history of hay fever should carry either over-the-counter anti-allergy medications or those prescribed by the doctor at all times. Regular once daily antihistamines, such as cetirizine or loratidine, should be taken daily throughout the pollen season to prevent hay fever symptoms – they are less effective if used as-and-when.

Depending on your symptoms, antihistamine tablets can be supplemented safely with a nasal spray and/or eye drops to keep your condition under control and allow you to enjoy the warmer weather.

Wear sunglasses

Sunglasses help to prevent pollen getting in the eyes and causing symptoms such as itching, swelling, red and runny eyes.
