Remarks
In severe asthma attack, preferably administer salbutamol by nebulisation, in combination with ipratropium. Use salbutamol metereddose inhaler only if nebuliser solution is not available.
Salbutamol is also used for other conditions associated with bronchoconstriction (e.g. chronic obstructive pulmonary disease, some severe respiratory infections).
Clean the mouthpiece before and after each use.
Do not pierce or incinerate used aerosol containers (risk of explosion).
