Generic name: pirbuterol acetate
Dosage form: Inhalation Aerosol
This dosage information does not include all the information needed to use Maxair safely and effectively. See full prescribing information for Maxair.
The information at Drugs.com is not a substitute for medical advice. ALWAYS consult your doctor or pharmacist.
The usual dose for adults and children 12 years and older is two inhalations (400 mcg) repeated every 4-6 hours. One inhalation (200 mcg) repeated every 4-6 hours may be sufficient for some patients.
A total daily dose of 12 inhalations should not be exceeded. If a previously effective dosage regimen fails to provide the usual relief, medical advice should be sought immediately as this is often a sign of seriously worsening asthma which would require reassessment of therapy.
As with all aerosol medications, it is recommended to prime (test) MAXAIR Inhaler before using for the first time and in cases where the inhaler has not been used for more than 2 weeks. Prime by releasing three “test sprays” into the air away from yourself and other people.
