Question: how many puffs are in a 90 mcg inhaler?
Answer: For bronchospasm associated reversible obstructive airway disease (i.e., asthma). 180 mcg (2 puffs) every 4 to 6 hours as needed. In some patients, 90 mcg (1 puff) every 4 hours may be sufficient. FDA-approved labeling recommends to not exceed 12 puffs/day.
