Xopenex HFA Dosage

Dosage form: aerosol, metered
Drug class: Adrenergic bronchodilators

Medically reviewed by Last updated on Jan 1, 2024.

Recommended Dosages

The recommended dosage of XOPENEX HFA for adults and children 4 years of age and older is 2 inhalations (90 mcg of levalbuterol free base) repeated every 4 to 6 hours; in some patients, 1 inhalation (45 mcg of levalbuterol free base) 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

For oral inhalation only

  • Shake well before use
  • Avoid spraying in the eyes
  • Prime the inhaler before using for the first time and when the inhaler has not been used for more than 3 days by releasing 4 test sprays into the air, away from the face
  • To maintain proper use of XOPENEX HFA, it is critical to wash the actuator with warm water and air-dry thoroughly at least once a week. The inhaler may cease to deliver levalbuterol tartrate if not properly cleaned and dried thoroughly. Keep the plastic actuator clean to prevent medication build-up and blockage. If the actuator becomes blocked with levalbuterol tartrate, wash the actuator to remove the blockage
  • The canister is fitted with a dose indicator, which indicates how many inhalations remain. The dose indicator display will move after every tenth actuation. When nearing the end of the usable inhalations, the color behind the number in the dose indicator window changes to red. Discard the inhaler when the dose indicator display window shows zero, corresponding to the use of 200 actuations
