In the United States, it is indicated as an add-on maintenance treatment for severe asthma with an eosinophilic phenotype in patients aged 6 years and older, CRSwNP in adults, and inadequately controlled chronic obstructive pulmonary disease (COPD) with an eosinophilic phenotype in adults.

Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration).

Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
