Flunisolide is a prescription medication used to treat various conditions.
There are two different flunisolide products:
Aerobid is approved to prevent
asthma attacks, while Nasarel nasal spray is approved to treat a stuffy, irritated, or runny nose due to
allergies.
How Does Flunisolide Work?
Flunisolide is a medication that belongs to a group of drugs called corticosteroids, or steroids for short.
Inhaled steroids (like Aerobid) go directly into the lungs and help to decrease the inflammation of airways that makes asthma attacks more likely. Because flunisolide does not work quickly, it should not be used for treating an
asthma attack. Rather, it is used twice a day in order to prevent asthma attacks.
Steroid nasal sprays (like Nasarel) are sprayed directly onto the nasal surface. They help to reduce inflammation associated with allergies and other conditions.
Because flunisolide is sprayed directly into the lungs or nose, the rest of the body is exposed to lower steroid levels, compared to steroids taken by mouth or injection. This helps reduce or eliminate many of the side effects associated with long-term steroid use.
