About asthma
Asthma is a common chronic respiratory condition affecting around 1 in 13 adults and 1 in 5 children in Ireland (HSE / Asthma Society of Ireland estimates). It involves inflammation, narrowing, and increased mucus production in the airways. Good control with appropriate inhaler therapy is achievable for the vast majority of patients, and significantly reduces both daily symptoms and the risk of severe attacks.
Symptoms and signs
- Wheeze — whistling sound when breathing, especially on exhalation
- Shortness of breath or feeling of tight chest
- Cough — often worse at night, in the early morning, or after exercise
- Symptoms triggered by cold air, exercise, allergens (pollen, dust, animals), respiratory infections, or stress
- Variable symptoms — better at some times, worse at others
Causes and triggers
Asthma typically develops on a background of genetic predisposition (family history, atopy) combined with environmental factors. Common triggers per NICE CKS: viral upper respiratory infections, exercise, cold air, allergens, smoke, occupational exposures, NSAIDs (in some patients), and emotional stress. Identifying and avoiding your specific triggers is a core part of management.
When to seek help — and urgent red flags
An Online Doctor consultation is appropriate for: routine prescription renewal of stable asthma medication, annual review for well-controlled asthma, advice on inhaler technique, or adjustment of preventer dosing. Seek urgent care (999/112 or emergency department) immediately if you have any of: needing reliever inhaler every 4 hours or sooner; unable to speak in full sentences; lips or fingers turning blue; reliever not improving symptoms; peak flow below 50% of your normal best. These are signs of acute severe asthma — a medical emergency.
Treatment options
Treatment per NICE and Irish College of General Practitioners guidance is stepped, based on symptom frequency and control:
- Reliever inhaler — short-acting beta-agonist (e.g. salbutamol/Ventolin) for symptom relief. If needed more than 2–3 times a week, control is inadequate
- Preventer inhaler — low-dose inhaled corticosteroid (ICS) taken daily, usually first-line for any patient using a reliever regularly
- Combination inhaler (MART regimen) — ICS + formoterol used as both preventer and reliever; current NICE-recommended approach for many adults
- Add-on therapy — leukotriene receptor antagonist (montelukast), long-acting beta-agonist (LABA), or higher-dose ICS
- Specialist referral for severe or difficult-to-control asthma — consideration of biologics
Self-care and lifestyle
Every patient with asthma should have a written asthma action plan outlining maintenance dose, when to step up, and when to seek emergency care. Annual flu vaccination is recommended (free under HSE for at-risk groups). Smoking cessation is critical. Identify and avoid personal triggers. Correct inhaler technique is essential — ask your pharmacist or doctor to review. Carry your reliever inhaler at all times.
Frequently asked questions
Can I get my inhaler prescription renewed online?
Yes — for clinically stable asthma where you've had a recent review and your control is good. The Online Doctor will check current symptoms, reliever use frequency, and any recent exacerbations. If asthma is poorly controlled or you haven't had a review in over a year, an in-person assessment may be recommended.
How often should I have an asthma review?
Per HSE and ICGP guidance, every adult and child with asthma should have at least an annual structured review covering symptom control, reliever use, inhaler technique, and adjustments to treatment.
Is asthma a contraindication for pregnancy?
No — well-controlled asthma poses minimal risk in pregnancy. Inhaled corticosteroids and salbutamol are safe in pregnancy. Uncontrolled asthma poses real risks to mother and baby — so continuing inhalers as prescribed is important.
Should I switch to a "greener" inhaler?
HSE and HPRA are encouraging consideration of lower-carbon-footprint dry-powder inhalers (DPIs) where clinically appropriate. Discuss with your Online Doctor — switching is only suitable for some patients and only when control will be maintained.
