What the FDA labels say
From the Fluticasone and salmeterol (Fluticasone Propionate and Salmeterol) label · effective 2025-08-21
In this situation, the patient requires immediate reevaluation with reassessment of the treatment regimen, giving special consideration to the possible need for replacing the current strength of Fluticasone Propionate/Salmeterol MDPI with a higher strength, adding additional inhaled corticosteroid, or initiating systemic corticosteroids.
Three (3) trials included adult and adolescent subjects aged 12 years and older: 1 trial compared budesonide/formoterol to budesonide, 1 trial compared fluticasone propionate/salmeterol inhalation powder to fluticasone propionate inhalation powder, and 1 trial compared mometasone furoate/formoterol to mometasone furoate.
Cases of serious eosinophilic conditions have also been reported with other inhaled corticosteroids in this clinical setting.
From the Mometasone (ASMANEX HFA) label · effective 2026-07-07
Lung function (FEV 1 or PEF), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of oral or other systemic corticosteroids.
In a 2-year double-blind study in 103 male and female asthma patients 18 to 50 years of age previously maintained on bronchodilator therapy (Baseline FEV 1 85%-88% predicted), treatment with mometasone furoate dry powder inhaler 200 mcg twice daily resulted in significant reductions in lumbar spine (LS) BMD at the end of the treatment period compared to placebo.
In clinical trials, concurrent administration of ASMANEX HFA and other drugs, such as short-acting beta 2 -agonist and intranasal corticosteroids have not resulted in an increased frequency of adverse drug reactions.
An inhaled, short-acting beta 2 -agonist, not ASMANEX HFA, should be used to relieve acute symptoms such as shortness of breath.
When prescribing ASMANEX HFA, the physician must also provide the patient with an inhaled, short-acting beta 2 -agonist (e.g., albuterol) for treatment of acute symptoms, despite regular twice-daily (morning and evening) use of ASMANEX HFA.
