Clinical monograph

How it works

It binds glucocorticoid receptors to suppress the transcription of multiple pro-inflammatory mediators, reducing mucosal and airway inflammation.

Prescribing in practice

  • Inhaled and intranasal corticosteroids are for regular preventive use and do not relieve acute symptoms; abrupt high-dose or prolonged use carries a risk of systemic corticosteroid effects including adrenal suppression.
  • Advise rinsing the mouth after inhaled use to reduce the risk of oral candidiasis and dysphonia.
  • Use the lowest effective dose and review inhaler technique and adherence regularly.

Monitoring

Monitor symptom control and, with prolonged or high-dose use, watch for local candidiasis and signs of systemic corticosteroid exposure, including growth in children.

Counselling the patient

  • Use this every day as a preventer even when you feel well; it will not give instant relief.
  • Rinse your mouth and spit out after each inhaled dose.
  • Do not stop suddenly after long-term use without medical advice.

Evidence & guidelines

Inhaled corticosteroids are an established cornerstone of asthma maintenance therapy in NICE and national asthma guidance.
