What is Cinqair?

Cinqair is a prescription medicine used with other asthma medicines for the maintenance treatment of asthma in people aged 18 years of age and older whose asthma is not controlled with the current asthma medicines. When added to other medicines for asthma, Cinqair helps prevent severe asthma attacks (exacerbations) and can improve your breathing. Medicines such as Cinqair reduce blood eosinophils. Eosinophils are a type of white blood cell that may contribute to your asthma.

  • Cinqair is not used to treat other problems caused by eosinophils.
  • Cinqair is not used to treat sudden breathing problems.

It is not known if Cinqair is safe and effective in children less than 18 years of age.
