Helping your patients manage asthma in allergy season

As allergy season approaches, many patients find that their asthma symptoms worsen.1 Although these two conditions aren’t the same, epidemiological studies have consistently shown that asthma and allergic rhinitis often coexist in the same patients.2,3 We have compiled some tips to help both you and your patients manage their asthma during this period.

Allergy season typically runs from March to September and is a result of the increase in pollen, causing allergic rhinitis in sufferers.1,4 One of the most common hay fever triggers is grass pollen, which mainly affects sufferers between May and July.4,5 Seasonal allergic rhinitis affects around 25.7% of the adult population in the USA.6 Many people find that their asthma symptoms worsen or can be triggered by allergies, with more frequent emergency hospital admissions noted.2 Studies have shown that the prevalence of asthma is more than six times higher in those suffering with allergic rhinitis who are exposed to pollen than those without.7

Typical symptoms of allergic rhinitis include sneezing, itchy nose and throat, blocked nose and itching eyes, which occur on contact with an allergen (pollen, dander, dust mites).1,8 Asthma symptoms include wheezing, chest tightness, and difficulty breathing.9 Successful control of allergies, alongside effective asthma management, could help improve symptoms and reduce asthma flare ups, according to UK charity Asthma+Lung.10

Urge patients to take antihistamines and intranasal steroid sprays

Antihistamines are a common treatment for allergy symptoms and can be taken two to four weeks before the patient usually gets symptoms during allergy season.11,12 This can help protect against pollen allergies.12

Intranasal corticosteroid sprays have been shown to relieve allergic rhinitis symptoms.13 Interestingly, they have also been shown to be moderately effective with asthma, which may lead to reducing asthma exacerbations and hospitalisations.2

Encourage patients to take their preventer inhaler as prescribed, and carry their reliever inhaler with them

Educating patients on taking their asthma medication as prescribed is crucial.10,15 This is significant year-round to control asthma, however, if patients suffer with allergy-induced asthma, it can be especially important to make sure that they are taking their preventer inhalers as prescribed.10 It is also vital in this period that patients keep their reliever inhalers on them in case of a flare up of symptoms.10

Consider performing a FeNO test on patients to help manage their asthma.16 In the clinic, FeNO testing can help ensure that patients are taking medications correctly, as a study showed that approximately 50% of adult patients on long-term therapy are non-adherent to their medication.16,17 FeNO testing can help guide treatment options through dose titration, checking inhaler technique, and monitoring asthma management at point-of-care.18,19

Manage the sneezing and the wheezing

Overall, it is important to manage both allergy and asthma symptoms to improve outcomes.22,23 As suggested by the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines, patients with persistent allergic rhinitis should be evaluated for asthma, and patients with asthma should be evaluated for rhinitis.24 Costs for asthma are significantly increased in patients with allergic rhinitis, so effective treatment of both may help to reduce these alongside improving patient outcomes.25,26 We hope that you can use the information in this article to help your patients manage their symptoms better during this season.
