ICS + LABA combination inhaler

Beclometasone with formoterol

Brand names: Fostair

Used in: Asthma

This is a combination inhaler of the inhaled corticosteroid beclometasone with the long-acting beta-2 agonist formoterol, used for maintenance treatment of asthma and COPD and, in some products, as combined maintenance and reliever therapy in asthma.

Dosing — being independently re-sourced

ClinCalc Pro is rebuilding its dose data from primary open sources — the manufacturer SmPC (eMC), the WHO Model Formulary and other official references — under clinician review. This drug's structured dose is not yet published here. Confirm all doses against the product SmPC and your local formulary before prescribing.

Clinical monograph

How it works

Beclometasone suppresses airway inflammation via glucocorticoid receptors while formoterol provides rapid-onset, long-acting bronchodilation through beta-2 adrenoceptor stimulation.

Prescribing in practice

  • Most important: in asthma a long-acting beta-2 agonist must always be combined with an inhaled corticosteroid, so this fixed inhaler should replace, not supplement, any separate LABA and steroid adherence is essential.
  • Where licensed for maintenance-and-reliever therapy, ensure the patient understands the single-inhaler regimen and does not also use a separate LABA reliever.
  • Prescribe by brand and device, as extra-fine formulations are not dose-equivalent to other combinations.

Monitoring

Monitor asthma or COPD control, inhaler technique, oral candidiasis, and growth in children on long-term inhaled corticosteroid.

Counselling the patient

  • Rinse the mouth after dosing to lower the risk of oral thrush.
  • Follow the prescribed regimen exactly, particularly if this inhaler is also your reliever.
