Recommended Dosages

For treatment of acute episodes of bronchospasm or prevention of asthmatic symptoms, the usual dosage of XOPENEX HFA for adults and children 4 years of age and older is 2 inhalations (90 mcg) repeated every 4 to 6 hours; in some patients, 1 inhalation every 4 hours may be sufficient. More frequent administration or a larger number of inhalations is not routinely recommended.

If a previously effective dosage regimen fails to provide the usual response, this may be a marker of destabilization of asthma and requires reevaluation of the patient and the treatment regimen, giving special consideration to the possible need for anti-inflammatory treatment, e.g., corticosteroids.

Administration Information


Priming: It is recommended to prime the inhaler before using for the first time and in cases where the inhaler has not been used for more than 3 days by releasing 4 test sprays into the air, away from the face.

Cleaning: To maintain proper use of this product, it is critical that the actuator be washed with warm water and air-dried thoroughly at least once a week. The inhaler may cease to deliver medication if not properly cleaned and dried thoroughly. Keeping the plastic actuator clean is very important to prevent medication build-up and blockage. If the actuator becomes blocked with drug, washing the actuator will remove the blockage.
