Flonase Use After Septorhinoplasty?

I am 17 days post op and my doctor gave me Flonase to help suppress the internal swelling that was severely bothering me. I am very healthy with no allergies or other complications. The surgery went very well and I have had almost no bleeding post op. He said I was healing very well. What are the drawbacks to using Flonase this soon after septorhinoplasty and are there any short or long term side effects? Can it impair healing or cause long term damage to my nasal linings?.
