Bronchospasms can also occur in people with chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema.
In the United States, this medication is no longer available. Sales were halted due to concerns about chlorofluorocarbons (CFCs), chemicals that may deplete the ozone layer.
