Xopenex HFA is an effective short-acting rescue inhaler for the treatment of asthma in children, adolescents, and adults
Xopenex HFA (pronounced zō-pen-eks) is a kind of medication known as a rescue bronchodilator, which is a quick-relief treatment option to relieve symptoms during an asthma attack. The medicine, taken via inhaler, works by relaxing tightened muscles around the airway passages, helping to relieve coughing, wheezing, shortness of breath and chest tightness caused by asthma.
Xopenex works within minutes to relieve symptoms (around 5.5–10.2 minutes in adults and adolescents, and 4.5 minutes in children 4–11 years old).

Always use Xopenex HFA exactly as your doctor has instructed you. Xopenex HFA is for oral inhalation use only. Keep Xopenex HFA and all medicines out of the reach of children.
Canister: The canister fits into the actuator. Do not place the canister under water to find out the amount of medicine left in the canister.
Actuator: The actuator holds the canister. Do not use the Xopenex HFA actuator with a canister of medicine from any other inhaler.
Dose Indicator: The dose indicator display window will show you how many sprays of medicine you have left in your inhaler. Each canister of Xopenex HFA contains enough medicine for you to spray your medicine 200 times. When the dose indicator display window shows a red zone, approximately 20 inhalations are left, and a refill is required.
