Adults and Children: A suitable starting dose of salbutamol by wet inhalation is 2.5 mg, administered 3-4 times daily by nebulization.
However, in domiciliary practice, the benefits of increasing the dose of nebulized salbutamol should be weighed against the risk that a deterioration in the patient's underlying conditions may be masked. In such circumstances, a medical assessment should be considered since alternative therapy may be indicated. Treatment may be repeated four times daily. Salbutamol solution for inhalation is intended to be used undiluted. However, if prolonged delivery time is desirable (more than 10 minutes) dilution using sterile normal saline for injection as a diluent may be required.
Salbutamol solution for inhalation is to be used with a nebulizer, under the direction of a physician. The solution must not be injected. Clinical efficacy of nebulized salbutamol in infants under 18 months is uncertain. As transient hypoxemia may occur, supplemental oxygen therapy should be considered.
