How is XOPENEX HFA taken?
XOPENEX HFA is administered by the use of a pressurized metered-dose inhaler, which produces a fine mist that can be inhaled. Your healthcare provider will instruct you on the correct use of your metered-dose inhaler and also give you written instructions. The usual dose of XOPENEX HFA is 2 inhalations repeated every 4 to 6 hours. One inhalation every four hours may be sufficient in some patients. It is very important that you use XOPENEX HFA as directed by your healthcare provider.
