I'm currently using avamys fluticasone furoate nasal spray. Is there a side effect from using this n how long can I use it safely?

Steroid nasal spray. Nasal sprays containing small doses of corticosteroids are a mainstay of allergy treatment and are generally very safe when used as directed. The most frequent side effects are nasal irritation and nosebleeds. The latter are suspected to occur with nasal yeast infections. These are not usually serious and improve with taking a break in medication use and with using salt water sprays; irrigation.
