What should you know about severe eosinophilic asthma?

Eosinophils are immune cells that can contribute to inflammation in the airways. People with this asthma pattern may have recurring wheezing, cough, chest tightness, and breathlessness despite regular treatment. Symptoms can coexist with Allergic Rhinitis or House Dust Mite Allergy, but eosinophilic asthma is identified through the overall clinical picture and tests rather than symptoms alone. A clinician may review lung function, blood results, previous attacks, inhaler use, and exposure triggers.

Use preventer and reliever inhalers exactly as prescribed, and check your inhaler technique with a clinician or pharmacist. Keep an agreed asthma action plan, record changes in symptoms, and reduce known irritants such as smoke and dust where practical. Specialist treatment may include medicines that target airway inflammation; the choice depends on your history and test results. A Nebuliser Treatment may be used in urgent settings, but it is not a substitute for an individual plan.

Call emergency services if you are struggling to breathe, cannot speak comfortably, become drowsy or confused, develop blue or grey lips, or do not improve with your prescribed reliever. Seek prompt review after an attack, when reliever use is increasing, or when night symptoms and activity limits are returning. Do not wait for a routine appointment if breathing is rapidly deteriorating.

What tests support an eosinophilic pattern? Is my inhaler technique effective? When should I use urgent care? Would specialist treatment be appropriate for my symptom pattern?
