What is Fasenra?
Fasenra is a prescription medicine used with other asthma medicines for the maintenance treatment of asthma in people 12 years and older whose asthma is not controlled with their current asthma medicines. Fasenra helps prevent severe asthma attacks (exacerbations) and may improve your breathing. Medicines such as Fasenra reduce blood eosinophils. Eosinophils are a type of white blood cell that may contribute to your asthma.
- Fasenra is not used to treat other problems caused by eosinophils.
- Fasenra is not used to treat sudden breathing problems. Tell your healthcare provider if your asthma does not get better or if it gets worse after you start treatment with Fasenra.
It is not known if Fasenra is safe and effective in children under 12 years of age.
