Disease background and treatment goals
Asthma involves variable airway narrowing and inflammation. Symptoms can fluctuate, so feeling well between attacks does not necessarily mean airway inflammation has resolved. [W]
How the medicines relate to the condition
Inhaled corticosteroids — Inflammation control
Reduce airway inflammation over time. Technique and continued use matter; a single symptom-free day is not a stopping rule. [C2]
ICS–formoterol combinations — Maintenance / relief in selected plans
Combine an anti-inflammatory medicine with a bronchodilator. Not every combination inhaler is suitable for reliever use. [C1]
Understanding selection and combination treatment
Inhaled corticosteroids address inflammation. Some plans use an inhaled corticosteroid with formoterol for both maintenance and relief; eligibility depends on age, severity and the exact product. A long-acting bronchodilator should not be treated as a stand-alone asthma anti-inflammatory medicine. [C1]
Monitoring, risks and reassessment
Ask a professional to check technique and write an action plan covering worsening symptoms and when to seek urgent help. More symptoms or increasing reliever use should trigger reassessment of control and adherence. [C1]
Questions for a clinician or pharmacist
1. Which inhaler is for maintenance and which is for relief?
2. Is my exact combination licensed for the proposed use locally?
