Administration Information

Administer ASMANEX HFA only by the orally inhaled route [see Instructions for Use in the Patient Information leaflet]. After each dose, advise patients to rinse their mouth with water and, without swallowing, spit out the contents to help reduce the risk of oropharyngeal candidiasis.

Remove the cap from the mouthpiece of the actuator before using ASMANEX HFA.

Prime ASMANEX HFA before using for the first time by releasing 4 test sprays into the air, away from the face, shaking well before each spray. In cases where the inhaler has not been used for more than 5 days, prime the inhaler again by releasing 4 test sprays into the air, away from the face, shaking well before each spray.

Only use the ASMANEX HFA canister with the ASMANEX HFA actuator. Do not use the ASMANEX HFA actuator with any other inhalation drug product. Do not use actuators from other products with the ASMANEX HFA canister.

Recommended Dosage

Administer ASMANEX HFA as two inhalations twice daily every day (morning and evening) by the orally inhaled route. Shake well prior to each inhalation. If symptoms arise between doses, use an inhaled short-acting beta2-agonist for immediate relief. The maximum benefit may not be achieved for 1 week or longer after beginning treatment. Individual patients may experience a variable time to onset and degree of symptom relief.

Adult and Adolescent Patients Aged 12 Years and Older

For patients 12 years of age and older, the dosage is either 2 inhalations twice daily of ASMANEX HFA 100 mcg or 200 mcg. The starting dosage is based on previous asthma therapy and disease severity, including considerations of the patients' current control of asthma symptoms and risk of future exacerbations. The recommended starting dosage for patients 12 years of age and older who are not on an inhaled corticosteroid is ASMANEX HFA 100 mcg, 2 inhalations twice daily. It is recommended that patients currently receiving chronic oral corticosteroid therapy (e.g., prednisone) begin with ASMANEX HFA 200 mcg (2 inhalations twice daily). For patients who do not respond adequately to the initial dosage after 2 weeks of therapy, increasing the dosage may provide additional asthma control. The maximum daily recommended dose is two inhalations of ASMANEX HFA 200 mcg twice daily (maximum of 800 mcg a day).

After asthma stability has been achieved, it may be desirable to titrate to the lowest effective dosage to reduce the possibility of side effects.

If a dosage regimen of ASMANEX HFA fails to provide adequate control of asthma, re-evaluate the therapeutic regimen and consider additional therapeutic options, e.g., replacing the current strength of ASMANEX HFA with a higher strength, initiating an inhaled corticosteroid and long-acting beta2-agonist combination product, or initiating oral corticosteroids.

Pediatric Patients Aged 5 to Less Than 12 Years

For patients aged 5 to less than 12 years, the dosage is 2 inhalations of ASMANEX HFA 50 mcg twice daily. The maximum daily dosage is 200 mcg.
