first steroid nasal sprays if used properly will not weaken your son's immune system. they are very safe and effective medications for treating allergy symptoms. many steroid nasal sprays are indicated for children as young as two years old. so i am not sure which nasal spray was prescribed for your son or where the information you are reading came from. i would suggest you check with your pharmacist if you are concerned.
the steroid nasal spray for my 6 year old son is for use in children 12 years & older. why did his doctor prescribe it? . will the amount of steroid in the nasal spray weaken his immune system?
