Ventolin Inhaler Dosage/Direction for Use

VENTOLIN has a duration of action of 4 to 6 hours in most patients.
Increasing use of beta₂-agonists may be a sign of worsening asthma. Under these conditions, a reassessment of the patient's therapy plan may be required and concomitant corticosteroid therapy should be considered.
As there may be adverse effects associated with excessive dosing, the dosage or frequency of administration should only be increased on medical advice.
VENTOLIN Inhaler is administered by the oral inhaled route only.
In patients who find coordination of a pressurised metered-dose inhaler difficult, a spacer may be used with VENTOLIN Inhaler.
Babies and young children using the VENTOLIN Inhaler may benefit from the use of a paediatric spacer device with a face mask (for example the BABYHALER) (see Clinical Studies under Actions).
RELIEF OF ACUTE BRONCHOSPASM: Adults: 100 or 200 micrograms. Children: 100 micrograms, the dose may be increased to 200 micrograms if required.
PREVENTION OF ALLERGEN OR EXERCISE-INDUCED BRONCHOSPASM: Adults: 200 micrograms before challenge or exertion. Children: 100 micrograms before challenge or exertion. The dose may be increased to 200 micrograms if required.
CHRONIC THERAPY: Adults: Up to 200 micrograms four times daily. Children: Up to 200 micrograms four times daily.
On demand use of VENTOLIN should not exceed four times daily. Reliance on such supplementary use or sudden increase in dose indicates deteriorating asthma (see Precautions).
