Hayfever helpers

As hayfever season returns, how can pharmacy teams advise customers to manage their symptoms effectively?

Around 49 per cent of people report suffering with hayfever symptoms, according to recent research from Allergy UK

Hayfever is caused by an allergy to the pollen produced by plants and trees and can affect people in different ways – with symptoms including sneezing, coughing, a runny or blocked nose, itchy, red or watery eyes, issues in the upper respiratory tract, and there are a variety of triggers that can make the condition worse.

Increased exposure to airborne irritants such as cigarette smoke can exacerbate hayfever, as can moving house, job or school to a more plant-rich area. Stress can also worsen hayfever as it undermines immune function, and anyone who already has sensitive eyes is more likely to react to pollen in the atmosphere, as their eyes are already inflamed and reactive. 

While there is no conclusive answer as to why some people have hayfever and others don’t, evidence suggests allergies may be inherited. 

"If your parents suffer from allergies, you will be 30-50 per cent more likely to have allergic reactions," says Hallam Wilshire, pharmacist at John Bell & Croyden. "And there are other risk factors such as additional atopic conditions – having asthma and/or eczema can increase your risk of developing hayfever."

Climate impact

In the UK, pollen exposure is most common in the spring and summer months, but different species of plants pollinate at different times of year, so some people may experience symptoms at specific times and none at others – and climate change is also aggravating the effects of allergies.

“For those that do suffer, it’s likely that the hayfever season will be longer and more intense this summer,” says community pharmacist, Sultan Dajani from GoldenEye. “A US study found the pollen season increased by 20 days and the pollen concentration by 21 per cent between 1990 and 2018, and this change is attributed to climate change and warmer temperatures.”

OTC options


The most common class of medicines used to treat hayfever are antihistamines – in tablet form, but also as eye drops and creams – which block the effects of histamine, a substance usually released when the body sees itself as under attack from a foreign allergen. 

"Under normal circumstances, the body produces histamines to help keep the sufferer alert, attentive and awake", explains Max Wiseberg, creator of HayMax Allergen Barrier Balm, "but hayfever sufferers respond to the presence of allergens by over-producing histamine because their bodies mistakenly identify the allergen as a threat, and too much histamine in the body produces those symptoms all too familiar to hayfever sufferers".

Antihistamines are classified in two ways: the first-generation antihistamines, such as chlorphenamine, work over four to six hours and can often cause drowsiness, with several doses required throughout the day. Second-generation antihistamines, such as cetirizine, loratadine, and fexofenadine, work over 24 hours and are less likely to cause drowsiness and only require once daily dosing. 

"In tablet form antihistamines will tackle most allergy symptoms including sneezing, itching, and watery eyes but may not help with congestion," says Hallam. "So tablets, sprays and drops can be taken individually or in combination to help combat other symptoms, depending on which the customer is experiencing and how severe they are."

Eye drops

With the pollen season lengthening and intensifying, hayfever sufferers can expect an upsurge in eye inflammation and eye infections, but there are a variety of products that can help.

"Sodium cromoglicate is an ingredient found in many allergy eye drops which is a mast cell modulator and helps reduce the release of histamine in the body," explains Hallam. "These drops need to be applied four times a day to each eye and continued throughout allergy exposure to maintain their effect."

Antiseptic eye drops can be useful in cases of allergic red, sore eyes. "They can help to prevent bacteria multiplying on the surface of the eye and causing an infection", says Sultan, "and if an infection does occur, there is an antibiotic eye ointment available OTC which can be recommended, but it is only for acute bacterial conjunctivitis from allergy related eye infections". 

"Some eye drops can also provide a protective barrier to the eye itself, whilst providing helpful lubrication through ingredients such as hyaluronic acid, and soothing qualities through ingredients such as the herb, chamomile," says Dr Richard Middleton, pharmacist and director of the British Herbal Medicines Association. "Look for products that are preservative-free for an additional benefit to those with inflamed, over-sensitive eyes."

Nasal sprays

Nasal sprays are a convenient OTC treatment whose popularity is on the rise, according to Cathy Crossthwaite, Numark’s OTC business development executive. "Over the last five years, the nasal spray category has increased from a 16 per cent share of space in 2017 to a 19 per cent share in 2021." 

Antihistamine sprays work by blocking the effect of histamine inside the nose, thereby reducing the allergic reaction, while steroid nasal sprays – which include drugs such as beclomethasone, fluticasone, mometasone, and budesonide – work by fighting inflammation and mucus production, reducing the allergic reaction of the nasal tissues to the inhaled allergen.

"Nasal steroid sprays are most effective at supressing nasal symptoms such as sneezing and congestion but may also relieve other hayfever symptoms like watery eyes", says Hallam, "but they need a week or so to become effective so need to be started ideally before allergy season starts and used regularly to maintain the effect".

Hallam also recommends nasal decongestants such as pseudoephedrine, which are available in tablet and nasal spray form. "These are particularly worthwhile when used in combination with antihistamines to work together to treat all allergy symptoms including congestion", he says, "but should not be used for longer than seven days except on the advice of a doctor".

Drug-free options

Many customers prefer natural or drug-free options to tackle allergy symptoms such as allergen barrier balms, immune boosting wellness formulae, air filters and air purifiers, acupressure hayfever bands, nasal filters and natural antihistamines such as quercetin and butterbur, available in capsules and tablets.

"This opens up a pharmacy’s offering to a wider customer base", adds Cathy, "as having a drug-free option in place allows pharmacies to support customers who are nervous around medication and whose prescription medication could be impacted by non-natural remedies – and also provides opportunities to showcase other natural remedies to customers, increasing total basket spend".

Pharmacy teams should also keep in mind that for first time sufferers, it can take several attempts to find the remedy which suits their symptoms. 

Antiseptic eye drops can be useful in cases of allergic red, sore eyes.

Animal allergies

People who suffer from hayfever and allergic asthma are often also allergic to animals, including those with fur, feathers or even scales. 

"Although the perception is that it’s animal hair that causes the problem for allergy sufferers, it is actually proteins in the saliva and dander of cats and dogs that trigger reactions for many people," says Alison Cullen, A.Vogel education manager.

"For most people symptoms only show when they encounter two or more things that they are allergic to at the same time," says Tracy Wright, physiotherapist and founder of CleanMyBed, a medical-grade chemical-free allergen removal system. "This is called 'symptom threshold' so, for example, if you are allergic to dogs, dust mites and pollen you may experience no hayfever symptoms until you are breathing in multiple allergic triggers at the same time."

Tracy advises the following strategies to help reduce pet dander allergy symptoms:

  • Restrict pets from furniture, carpeted areas, the bedroom and bed as far as possible
  • Wash and brush pets regularly (this should ideally be done by someone who is not allergic)
  • Wash pet bedding frequently
  • Wipe smooth surfaces in the home regularly
  • Use high-efficiency particle arresting (HEPA) filters and vacuum cleaners to regularly clean mattresses properly, removing both dust mites and pet dander.

Self care advice 

"The best way to treat an allergy is to avoid the allergen entirely, but this may be easier said than done," says Hallam. This means self care advice is an area where pharmacy staff can offer a whole host of simple tips that can make a big difference to customers’ symptoms: 

  • Dust regularly and vacuum often, ideally using a machine with a high-efficiency particle arresting (HEPA) filter
  • Avoid drying clothes outside. When washing is hung on the line, pollen will collect in it which is then brought into the house
  • Avoid cutting grass, playing or walking in grassy areas
  • Keep car windows closed and buy a pollen filter for car air vents
  • Don’t keep fresh flowers in the house
  • Don’t smoke or let others smoke in the house as smoke irritates the lining of the nose, eyes, throat and airways making symptoms worse
  • Wear glasses instead of contact lenses or wear daily disposable lenses to reduce the build-up of allergens on lenses
  • Wear wrap-around style sunglasses, which can reduce the amount of pollen entering the eyes by deflecting air currents carrying pollen
  • Remove pollen grains that enter the eyes by bathing with clean water, or artificial tears
  • Tie up long hair and wear a cap, hat or other head cover when outside to prevent pollen particles being caught in the hair
  • Thinly coat the skin around the nostrils and the bones of the eyes with liquid petroleum jelly or an organic, drug-free allergen barrier balm in the morning, throughout the day and at night to trap pollen
  • Cut back on dairy, which can be mucus-promoting in some people
  • Increase fresh fruit and vegetable intake as these are full of vitamin C, which is known to boost the immune system
  • There is some evidence that antioxidants can reduce the severity of allergy symptoms so swap to green tea for antioxidant support
  • Avoid alcohol as it may have an inflammatory effect
  • Shower at night to remove pollen particles from the hair and body
  • If hayfever is disrupting sleep, OTC herbal remedies containing valerian, hops, lemon balm or Passiflora can help, without the side-effects associated with conventional sleep medicines
  • Keep up with the pollen forecast via apps or the Met Office pollen forecast.

"Pharmacy staff should also advise customers to keep a diary of when symptoms appear, monitoring the severity", says Lucy Morris, Numark patient services manager, "to enable [staff] to provide bespoke one-to-one guidance on the best medication for the individual. For those who want further support, private allergy tests are available in some pharmacies, as well as pharmacy teams being able to advise patients on when they should seek additional support from their GP".
