Advair Side Effects

I have used Advair for about a year and quit because of severe dry mouth. I have been off Advair about a month. I no longer have sever dry mouth but my mout is still some what dry. Nothing like when I was still using Advair. I also suffer from cronic (chronic) sinusitis and asthma. How long can the dry mouth side effects of Advair persist after discontinuing? Thanks for your time.

This is not a common side effect from Advair. A sinus infection is another possible cause of this symptom.  I would suggest speaking to your physician about this.
