This is a compounded product?

1mg/ml..? Crikies!

The typical nasal steroids manufactured are in the microgram range.

I think your spray would leave alot SWALLOWED and hence become systemic.

I have never seen anyone with a compounded spray like this so strong!
No wonder you are having systemic effects. Not only would this affect
fusion, but also osteoporosis, and low potassium levels.

I found an interesting paper on the net..that discusses the fact that the nasal steroids do not get high enough into the nose, to really help some people.

What type of sprayer was provided? If the fancy shmancy devices do not work, I wonder if yours worked at all? If it sprayed just the nasal passages, you would swallow most of it. Lying on the bed with your head hanging back for a while might have allowed more local actions. (this is discussed in the article above) But I think the dose of this spray is really "out there" therapeutically.

Steroids, smoking and NSAIDs are the 3 known fusion blockers.
