Can I Nebulize My Toddler With A Mix Of Levolin And Budecort For Wheezing From Pollen And Dust Mite Allergies?

Hi, my son is 4years old and has a pollen and dust mite allergy since he was 1 year old, I have tried homeopathy but did not work, I use to nebulise him with levolin .63mg and sometime budecort .5 Mg. However I got his immunology treatment done and it helped in last one year but since last 2 days he has been getting major wheezing due to allergy season, can I nebusize him with a mix of levolin and budecort?
