How long after you stop using a steroid nasal spray will your immune system go back to normal if it was weakened?

    You added the clause at the end "if it was weakened."  It is not weakened if you don't exceed the dosage.  The daily dosage of the steroid in Nasacort when prescribed for immune suppression is more than 200x the dosage you receive with two squirts of the spray, or roughly 1.5x the total amount in the spray bottle.  The whole point of nasal sprays is to keep the dosage so small that it does not cause immune suppression.   So how long would it take for the immune system to get back to normal?  No more than  a couple of days since the effect on the immune system is almost non-existant even with prolonged use.
