Does Long Term Intake Of Montair FX And Metaspray Cause Any Side Effect?

Before one month I have gone through a nasal surgery. Details of the surgery is as follows:FESS/GA DNE done. Polyp B/L removed. B/L Uncinectomy & MMa done. B/L ethmoidectomy + Sphenoidotomy done. Hemostasis maintained.Now my doctor suggests me to take the tablet MONTAIR FX and Metaspray for another six months. Taking this medicine for a long term will cause any health problem?George ,Kannur
